Captain John Price x F! Royalty Reader

Summary: Y/N is part of the British Royal Family & is kidnapped by terrorists. John Price & Task Force 141 are given the responsibility of rescuing her before the ransom deadline

Warnings: mentions of torture, abuse, kidnapping, anxiety

Captain John Price was ready to kick his feet up & relax for the rest of the weekend. He had already cracked open a beer. With one click of the tv remote he knew his weekend would be anything other than relaxing.

“This just in her royal highness the Duchess of Windsor Y/N L/N has just been ambushed & is considered missing. The young Duchess was leaving a gala when armed men ambushed her vehicle & were able to successfully kidnap her. Her whereabouts are unknown at the moment & London is currently on lockdown near Buckingham Palace.” The news anchor on the television reported. A groan escaped his lips knowing this mission would come across his desk.

“Fuckin hell, “ He cursed to himself & looked up at the ceiling. “Lord I wanted one weekend, one fucking weekend is that too much to ask for?”

Right on cue his phone started to vibrate. Laswell in big letters flashed across his screen.

“Don’t even elaborate where do we need to be?” He asked rubbing his temples.

“Well hello to you too, meet me at headquarters as soon as possible.” She stated. He stood up & stretched before sending a message out to the rest of his team. He walked into his bedroom & pulled out his combat pants, combat thermal, & two pairs of socks. Price got dressed & laced up boots. The thought of the Duchess started to creep into his mind. He couldn’t even imagine what she was experiencing. The absolute fear of being at the mercy of international terrorists has to have terrifying.

Price made his way to his car & started it. He started to drive to the post & when he got to the gate he scanned his ID. The soldier saluted him & the gate arm lifted. He pulled up of the offices & started to walk into the building. Ghost, Gaz, Soap, & Alejandro were already sitting in the briefing room waiting for him. Laswell was already at the front of the room with the screen behind her turned on.

“Ah Captain Price! Good to see you! Sit down so we can start.” Laswell said. “Colonel Vargas & his team will be conducting this operation with us due to the severity of the situation.” Price sat down, & Laswell started her briefing. “So while we don’t know how the Duchess was able to be taken, we were able to pin her location. Seems like our terrorists didn’t do a good job at giving their location. They released a video with a list of their demands, & hefty ransom. It is disturbing I’ll admit. They’ve beaten this poor woman to hell & back already.” Laswell pressed a key on the laptop in front of her & the video started.

There sat the Duchess tied to a chair with smudged mascara & a black eye. She was trying her hardest to stay awake. The once beautiful pink gown she had on was covered in blood & dirt. Pure anger ran through Price’s veins seeing her in that state. Each of the terrorists had black balaclavas on & stood on either side of her.

“To the Royal Family & the United Kingdom, we are taking revenge. One by one each Royal family of each Western nation will start going missing if you do not fulfill our wishes. If you wan to see her again, let alone alive you will fulfill our wishes. The cost of her safe return is 500 million dollars. You have until midnight.” One of the Balaclava clad men demanded. He gripped her chin roughly & she protested at his grip. “You little cunt. You will respect me.” He lifted the hand that held a Glock in it & used the back of the gun to slap her across the face. A loud cracking noise happening & the video paused.

“Steamin’ Jesus,” Soap said. “Who are we dealing with?”

“The usual suspects.” Laswell replied. “We pinned their location & we have to act accordingly because it’s very clear their intentions will result in more violence. They’ve taken her to a warehouse in Romania, & we have their governments full permission to go in. So let’s get going, we lift off at 20:00.” She closed the laptop & everyone got up from their respective seats. Everyone started to funnel out of the conference room & started down to the air strip.

There was a heaviness in the air, they knew the weight on their shoulders. Not just the weight of the United Kingdom was on their shoulders but the entire western world. Alejandro’s team already had their gear laid out ready for inspection & he walked off to make sure they had everything.

“Alrighty lads lay out your gear for inspection.” Price shouted. One by one he went through each of their gear & made sure it was ready for use. Thankfully no one was missing anything. Two Blackhawk helicopters sat on the air strip waiting to take them over the border into Romania. 20:00 came faster then they had anticipated & both teams boarded the helicopters.

The usually chatty Task Force 141 sat in silence. They looked around at each other solemnly, & praying that the Duchess would be still alive. Price couldn’t get the image of her being brutalized. The men were familiar with her philanthropic efforts, & they were infuriated someone would go out their way to hurt her. Y/N had spent time overseas in incredibly dangerous countries delivering medicine herself, & showcasing what children in those countries go through. She was a saint in the public eye & overall was a incredibly kind woman.

“We are over the border gentlemen & in Romania. Fifteen minutes away from target.” The pilot had stated. They were all filled with pure adrenaline by this point eager to get on the ground. “Target located gentlemen.” The pilot. “Gods speed.” The warehouse was below them, & the fast ropes dropped. One by one both teams dropped men. Alejandro’s team took the ground & Task Force 141 took the roof. These terrorists clearly weren’t smart enough to plant guards on the roof.

Ghost kicked in the door the lead to the stairs. He threw in a grenade & then started to use the light on his rifle to lead the team in. They walked past bodies of the men hit by the grenade & started all the way down to the loading docks of the warehouse. Price could tell the warehouse hadn’t been used in years. Rust & mold were all over the metal of the building. Once they made it to the bottom of the stairs, they were greeted with the gun fire. Both Ghost & Price easily eliminated those threats.

Price could hear Alejandro’s team outside, the sound of the gun fire echoed through the building. The lights were completely knocked out but they were able to eliminate any & all targets.

“Captain!” Ghost yelled over the radio alerting Price. “Found her.” He ran over to the room were Ghost was. There she was, Y/N Windsor the Duchess of Windsor. Her ballgown was completely destroyed & was covered in wounds. Some deeper than others. She was entirely unconscious, poor thing couldn’t respond to Ghost’s questions. Thankfully she still had a pulse but it was evident she was hanging by a thread. Price picked her up & she was limp. “Ghost we need to get back to the helicopter.” He said. Over the radio Ghost had alerted Alejandro they had located the Duchess. Price held her close to his body, & tried to apply pressure to the more intense wounds. On the helicopter she was able to open her eyes, & saw the Union Jack on Price’s plate carrier. Still in his arms, she weakly lifted her arm up & pointed to the flag.

“Please don’t let me die,” she mustered out.

“Don’t worry darling, I won’t.” He replied. She then passed out again afterwards.

Finally they were able to get on board the helicopter & out of Romania. Once they had landed base on the air strip on base a ambulance was waiting for them. Price & Laswell sat in the back of the ambulance as a liaison for the Royals. Once at the hospital the staff took her & brought her immediately into surgery. Still covered in the Duchesses blood & sweat Price sat there in the waiting room his leg shaking out of anxiety. Laswell rubbed his back gently in an attempt to comfort him.

Eight hours of surgery later, the surgeon exited the operating room with good news. The Duchess was going to make a full recovery. A wave of relief washed over him. The news outlets were updated almost instantly by Buckingham Palace Officials. Price went everyday to the hospital to visit her. Although she was asleep & he still spoke to her. She infiltrated every single thought he had every waking moment. Soap had teased him a little bit about it only to be met with a death stare.

About a week later, she awoke to the sound of a deep British accent talking to her. The same one that had been in her dreams. She awoke to bright lights & the beeping of the heart monitor. Her moved around violently as she tried to take in her surroundings.

“Love, you’re alright you’re in the hospital.” The voice said as a hand started to pet her hair. She looked over & saw a man with full beard. He looked a little bit older than her. His blue eyes were amplified by the florescent hospital lighting. There was just so comforting about his presence. Two nurses came in & started to check on her vitals. She was able to answer as many questions as they threw at her. The mysterious man with the blue eyes still stood beside her. Once the two nurses left she turned to him.

“Who are you?” She asked. Her voice was meek & was cracking.

“Captain John Price your highness.” He replied. “I had helped lead the effort with my team to rescue you.” A flood of memories came back. She remembered the pain, & the blood stained Union Jack flag on his chest.

“I’m a man of my word love,” He replied & grabbed her hand.

“What?” She replied clearly the fog of amnesia still had it’s effect on her.

“I didn’t let you die love.” He replied. “I kept my promise.” His thumb brushed over her knuckles delicately. She gave him a soft smile in return.

“Thank you Captain Price,” she replied. Little did either one of them knew that this rescue would lead to the Royal Wedding of the decade.

SI Derived Units: Energy, Work, Heat, and the Joule

The SI derived unit of energy was officially adopted as the joule, after James Prescott Joule, in 1889, only months before Joule's death. It is defined a number of ways, including as "the amount of work done when a force of one newton displaces a mass through a distance of one metre in the direction of that force" and is equivalent to a number of other units. Work and heat are two specific types of energy and therefore also use the joule in SI units.

Mathematically, the joule is represented by a capital J; energy is represented by any number of letters and symbols depending on the usage of the term (energy on its own is often capital E; work capital W, and heat capital Q, but U is often used for internal energy, K for kinetic energy, etc.). The joule is equal to one newton meter, or one watt second, or one coulomb volt, but in base units is one kg m^2 s^-2. Equivalent energy units in other systems are too numerous to give in detail, but include the following: the erg, the kilowatt-hour, the calorie, the British thermal unit or BTU, the electronvolt, and the foot-pound-force.

The OIAR's very well funded response team headcanon (I havebbeen watching Torchwood too much)

Now, we know that Mr Bonzo is On His Way to deal with anyone the OIAR sics him on, but there is only one Mr Bonzo. What happens when one needs to catch a group of people in a building with a door they can all just leave through once Mr Bonzo arrives? Clearly, the OIAR needs their Response part to complement the Assessment.

The OIAR has terrible funding, just like the magnus institute, and so I'm guessing that any kind of response element would also be badly funded. Presumably the assault rifle carrying crazies who showed up at the hilltop road charity shop and proceeded to shoot everything and then firebomb it were an external organisation, associated with another Entity maybe. Thus we should base our OIAR crack hit squad on an even less well equipped group: The british police force.

We already have section 31, so the police clearly have some knowledge of paranormal activity and respond to it. The OIAR does not need to manage the entire country, in that case. So the team directly associated with them would be fairly small and deployed when the target is not going to be moving off anytime soon. Isolated avatars and creatures, and localised cults are unlikely to get wind that they are about to be attacked by a sleep deprived paramilitary who have to travel by train so this probably isn't much of an issue.

The equipment of this group would probably be based on british police equipment, though obviously with some modifications for dealing with possible paranormal activity. British armed police generally carry pistols and have taken up using rifles recently too. However, let us think. Does it seem likely that an eldritch touched being is likely to buy body armour. Not really. If a weak bullet doesn't stop it long enough to be dealt with a rifle bullet probably won't either, and given the cost constraints it would probably make sense that this response unit has pistols all around and perhaps a sniper rifle. Some kind of night vision or thermal imaging may also be useful in the case of entities messing around with the time of day, which does seem to happen rather a lot. To round out the actually reasonable equipment, a flashbang might help. It's hard to concentrate on using your mystical powers of death and destruction when your ears are bleeding.

Now we move to the more silly equipment (:3). Rope! Rope is great for when you are nervous about losing your way or climbing into a pitch dark hole. Maybe string would help too, come to think of it. Glowsticks should also be useful for testing the aforementioned pitch dark holes, or to make sure nothing is creeping around behind you (would leave a shadow). For that matter stick a torch on the guns. Some kind of analogue recording device would probably be nice as entities seem to be able to wreak havoc with any kind of electronics, so paper and pen basically. Motion sensors are quite cheap and easy to set up, so we can give them some of those too. Pepper spray is terribly boring but I think it might be useful.

The most important part of these people is obviously going to be their esoteric knowledge of entities and ability to keep a clear and logical head when everything goes pear-shaped and their friends get turned into pineapples or something. Ideally they should understand the broad strokes of meditation exercises, be able to get past contradictory sensual input and have experience being a part of at least one paranormal group (so that they understand the modus operandi of this type of thing). Additional helpful tricks might be being able to shoot very accurately, some kind of self hypnosis to force oneself to snap out of delusions of fear or literally being an avatar themselves.

The Eye runs the OIAR as it ran the Magnus Archives and I think we can all agree on this. The Eye is probably also very interested in the prospect of being able to subsume allll the knowledge that this response team manages to nick from the people they black bag and drive off in trucks with. So on some level the response team is just as much a branch of the Eye as the assessment people. I'm thinking mmm unusually keen eyed (miraculous recovery from needing glasses), people becoming compliant when interrogated, maybe a compulsion to be extra thorough when turning the target's house upside down for secret books, but only when there is one to be found (the Eye is good at secrets). Obviously the Hunt is going to be involved somewhere too but likely to a lesser extent than the Eye.

I did consider having them drive around in the alcoholic equivalent of a clown car but honestly this would probably get them found out rather easily. Instead, it's more likely that they would take the train with some kind of identification to allow them to travel with weapons (or the Eye just helps them not be noticed when they are on it). And THEN they get into the clown car, which is actually a "requisitioned" unmarked police van. Of course, not everywhere they go has these to spare. In fact, they seem to magically get misplaced as soon as the Voyeurs (nickname for how they sometimes get caught nose deep in filing cabinets) show up. In which case, it's time for walkies

TLDR: Group of understaffed paramilitary kick in your cult's front door and somehow know precisely where all your EVIL TOMES are kept. And then when you try to cast an incantation upon these poltroons they throw rocks at you. An alternative interpretation is if someone was to be going around making people think they're falling out of the sky, deploying a bunch of people of whom some have actually fallen out of the sky will probably help them keep it together.

once again it is time to post the LLNL energy consumption sankey diagram because i have seen at least three people this week making the error of thinking residential use and personal choice contributes any more than 12% of the energy budget

if residential energy use was 0%, if no one ever consumed any energy at home, we would still lose 67 quadrillion british thermal units to waste heat. the largest gains to be had by far are in recapturing lost energy, a topic that curiously no one discusses. fully two thirds of the energy we produce does not power anything

every discussion we have on this topic that is focused on residential use and personal choice amounts to obsessing over 8 quads of the budget to the exclusion of the other 92 of them. (if you look closely, residential use is twice as efficient as overall loss to waste. i almost got that wrong, and assumed residential use also loses two thirds to waste.) if all residential use was perfectly efficient, with no loss to waste, we would regain 4 quads. if overall usage was 6% more efficient... again, we would regain 4 quads!

if you want to talk about cars that's a different story, but this diagram does not separate out personal cars from industrial and commercial trucks, which makes it a bit less useful for that context. here's a pie chart from 2009 about it

cars also use 8 quads of the budget (29% of 27.5), but note that that includes commercial use like cabs and deliveries, and note that your commute is a cost you incur, when your commute emissions really ought to be your employer's responsiblity, since you wouldn't be driving there every day if they hadn't hired you. this is one of the only ways to turn a profit: abdicating responsibility for waste

i know everyone knows this and i've seen it said many times, that individual and personal choices will always pale vastly in comparison to industrial use, but the specific ratio by which commercial, industrial, and transportation use, and loss to waste, outnumber anything you do at home... is 12:1

please, please focus with me on the problems of scale instead of repeating the useful idiot dialogue that has been scripted for us

Waiting breathlessly for the apologia for the British Thermal Unit, the Cooling Ton, and the Brake Horsepower

I know that—objectively—this is bullshit, but I have chosen to believe that the reason the US hasn't formally changed to the metric system is for the poets. When the going gets tough you can still claw your way forward inch by inch, but centimeter by centimeter just doesn't quite carry you. You're in love/excited/nervous/scared and your heart is beating a hundred miles per hour, whoa that sounds fast and dangerous! But a hundred kph? I've been passed by people going faster than that coming out of downtown on capital boulevard. The pound of flesh they take from you is raw and bloody and full of pain, the kilogram of flesh is impersonal and excised in laboratory conditions under strict observation. Liters are okay tho, if only because they sound like meter and a meter is used to measure things, so the measure of a man can be siphoned (as a byproduct of the kilogram) into a bottle with a screw cap lid and stored in a dark cool room until he is found wanting. A gallon would be wasteful, a quart too unserious, and a cup not enough to keep him from withering in the desert sands under 100 degree faeghreignheit sun. ...Okay maybe celsius gets a pass too.

Why Small Air Conditioning Units Are Perfect for Compact Spaces

In today's world, urban living often means smaller living spaces. From studio apartments to tiny homes, the demand for efficient cooling solutions tailored to compact environments has never been higher. Small air conditioning units have emerged as a practical and effective option for those looking to maintain a comfortable indoor atmosphere without compromising valuable space. At Andrews Sykes Climate Rental, a leader in HVAC solutions across the Middle East, these units are designed to deliver optimal performance while fitting seamlessly into smaller areas.

The Rise of Compact Living

As cities continue to expand, more people are opting for smaller living arrangements. The trend towards minimalism and efficient use of space has led to the need for air conditioning solutions that do not take up excessive room. Traditional, bulky air conditioning systems can be impractical in compact spaces, often leading to cramped living conditions. In contrast, small air conditioning units provide the perfect balance of cooling power and spatial efficiency, making them an ideal choice for urban dwellers.

Understanding Small Air Conditioning Units

Small air conditioning units come in various types, including portable air conditioners, window units, and split systems. Each type has distinct advantages that cater to different needs. Portable units offer mobility, allowing users to move them from room to room, while window units are designed to fit snugly into window frames, maximizing floor space. Split systems are ideal for those seeking a more permanent solution without compromising wall space.

1. Space Efficiency

One of the primary benefits of small air conditioning units is their compact design. Unlike traditional systems that require extensive installation and space, these units are designed to fit into smaller areas without overwhelming the room's aesthetics. For instance, portable air conditioners can be easily tucked away when not in use, while window units blend seamlessly into the architecture of the building. This space-saving design allows residents to enjoy a comfortable living environment without sacrificing style or functionality.

2. Energy Efficiency

In addition to their compact size, small air conditioning units are often more energy-efficient than larger systems. Many models are equipped with advanced technology that optimizes performance while consuming less power. This is particularly beneficial for individuals living in smaller spaces, as energy costs can add up quickly. By utilizing a small air conditioning unit, residents can maintain a comfortable indoor climate without incurring exorbitant utility bills.

3. Targeted Cooling Solutions

Small air conditioning units provide the flexibility to cool specific areas rather than an entire building. This targeted approach is especially advantageous in compact living situations where only one or two rooms need cooling. For example, a portable air conditioner can be placed in the living room during the day and moved to the bedroom at night, ensuring comfort where it is needed most. This versatility allows residents to customize their cooling experience based on their daily activities and preferences.

Choosing the Right Small Air Conditioning Unit

Selecting the right small air conditioning unit involves considering various factors to ensure that it meets specific needs. Andrews Sykes Climate Rental offers a range of options, each designed to cater to different environments and cooling requirements. Here are some key considerations when choosing a small air conditioning unit:

1. Room Size

Understanding the size of the room where the unit will be used is crucial. Small air conditioning units are rated according to their cooling capacity, measured in British Thermal Units (BTUs). It is essential to select a unit with an appropriate BTU rating for the space to ensure efficient cooling. Andrews Sykes provides guidance on selecting the right unit based on room dimensions and cooling requirements.

2. Type of Unit

As mentioned earlier, small air conditioning units come in various types. Portable air conditioners are ideal for those seeking flexibility, while window units are perfect for permanent installations. Split systems offer a balance of both, providing powerful cooling without taking up valuable floor space. Evaluating the specific needs and preferences of the user will help determine the most suitable type of unit.

3. Energy Efficiency Ratings

When selecting a small air conditioning unit, it is essential to consider energy efficiency ratings. Units with higher Energy Efficiency Ratio (EER) scores consume less electricity while providing effective cooling. This not only helps reduce energy costs but also contributes to a more sustainable lifestyle. Andrews Sykes offers an array of energy-efficient models, ensuring that clients can make environmentally conscious choices.

Installation and Maintenance of Small Air Conditioning Units

Proper installation and maintenance are vital for the optimal performance of small air conditioning units. At Andrews Sykes, clients can benefit from professional installation services that ensure the unit is set up correctly and functions efficiently.

Installation Considerations

For window units, ensuring a proper fit in the window frame is crucial to prevent air leaks and maintain efficiency. Portable units require minimal installation, often needing only a power outlet and a window for exhaust. For split systems, professional installation is recommended to ensure that both the indoor and outdoor units are correctly positioned and connected.

Maintenance Tips

Regular maintenance is essential to keep small air conditioning units running smoothly. Here are some key maintenance tips:

Clean or Replace Filters: Clogged filters can significantly reduce the unit's efficiency. Regularly cleaning or replacing filters ensures optimal airflow and cooling performance.

Check for Leaks: Inspect the unit for any signs of refrigerant leaks, as this can affect cooling efficiency and may require professional service.

Keep Coils Clean: Dust and debris can accumulate on the coils, hindering the unit's ability to cool effectively. Regular cleaning of the coils is essential for maintaining performance.

Seasonal Start-Up and Shut-Down

At the beginning of the cooling season, it's essential to check the unit's functionality and perform any necessary maintenance tasks. Similarly, before shutting down the unit for winter, it’s advisable to clean it thoroughly and store it properly to extend its lifespan.

Features of a Commercial Air Conditioning Unit

Commercial air conditioning units must have a higher capacity than residential ones to cool large business spaces like offices or malls. They also come with features that optimize building efficiency.

For example, a centralized system uses ducts to distribute cooled air throughout the entire building. This allows temperature control for each zone.

Modularity

Modular air conditioning unit commercial systems allow varying levels of customization and performance. This makes them a suitable option for complex or unique environments. This level of customization also allows for easy maintenance. For example, if one unit breaks down, the others can pick up the slack to ensure that heating and cooling are still delivered.

In contrast, compact units are more standardized and provide an affordable solution for many applications. However, they may lack the scalability and flexibility that modular systems offer.

Property owners often struggle to economically modify their buildings to accommodate changing tenant requirements. A space that begins as a tradesman’s shop might suddenly be required to handle heavy computer usage, for instance. With a modular HVAC system, the owner can simply purchase additional modules to meet these new requirements without the cost of replacing the entire system. This approach also makes repairing and upgrading components easier, as they are less impacted by age or usage.

Noise

Many commercial AC units are loud enough to disrupt workplace productivity and even trigger health concerns for building occupants. However, noise levels are subjective and can differ across different industries and people. There are also regulations regarding sound levels inside city limits, so you should always consult an acoustic engineer or an expert to help you find practical solutions that minimize the amount of noise your AC produces.

When your air conditioning makes unusual sounds, it’s important to address the issue promptly to avoid costly repairs and downtime. For example, rattling noises may indicate loose panels that can be tightened with simple tools. A squealing sound can signify a motor that needs lubrication or, in more severe cases, replacement.

Other noises like whistling can occur when machines are too close to vents or if there’s excess dirt and debris in your ductwork. These issues can restrict airflow and cause the system to work harder, leading to increased noise production.

Energy Efficiency

Choosing energy-efficient commercial HVAC models is important for business owners who want to minimize operational costs while improving sustainability. Energy-efficient systems use less power to produce the same amount of cooling, reducing operating expenses and environmental impact.

Understanding SEER and EER ratings can help business owners select the most efficient air conditioning commercial system for their needs. Both ratings measure a system's efficiency by comparing its output in British Thermal Units (BTU) to its electricity usage in KiloWatt Hours under strict laboratory conditions.

Implementing energy-efficient strategies can further improve the efficiency of commercial air conditioning units. For example, sealing leaks in ductwork prevents heat transfer and reduces the workload of an air conditioning system. Also, routine maintenance helps keep systems running at peak performance. These measures may reduce energy consumption by up to 30%, saving money and cutting emissions. Energy efficiency is also important because it aligns with broader sustainability goals that many companies now adopt.

Maintenance

Commercial HVAC systems require regular maintenance to keep occupants comfortable and productive. This maintenance can include cleaning or replacing air filters, inspecting for leaks and lubricating parts. It also includes testing of the system’s performance to ensure it meets its energy efficiency goals and is operating at peak capacity.

Coil cleaning should be on every commercial AC unit maintenance plan. A dirty coil starves the system of air and can cause it to freeze up, resulting in costly repairs.

Drainage is another important area for commercial AC maintenance. Residential units drain into a small pan, but a commercial AC system needs more complex drainage systems to prevent overflows. Technicians inspect these systems for clogs and add drain tablets or pan treatments to prevent sludge buildup.

Routine inspections help catch problems before they become major commercial AC repair issues, like a broken compressor or a blown fuse. These inspections include looking at belts, filters and electrical connections. They can also check for signs of moisture or mold growth.

Finding the Right Fit: How to Size Your Electric Fireplace for Any Room

Electric fireplaces have grown in popularity, adding warmth, ambiance, and style to any room. But selecting the right size for your space is key to making it both functional and aesthetically pleasing. This guide will walk you through the steps of choosing the ideal electric fireplace size for various room types, taking into account factors like room dimensions, heating capacity, and design considerations.

Why Size Matters in Electric Fireplaces

Electric fireplaces come in many shapes and sizes, each suited for specific room dimensions. Choosing the right size helps ensure efficient heating and prevents a mismatch between the fireplace’s appearance and the room’s aesthetic.

Step 1: Measure Your Room

To get started, measure the length, width, and height of your room. Room size influences the heating capacity needed from your fireplace. For instance, electric fireplaces with 1,500-watt heating can typically heat up to 400 square feet, making them suitable for medium-sized rooms.

For accurate placement, measure the wall area where you plan to install or place your fireplace. Consider adding a few extra inches around the unit for an unobstructed view and ease of use.

Step 2: Understand Heat Output and Room Coverage

Electric fireplaces are rated by British Thermal Units (BTUs), which measure heating output. Here’s a basic guide to matching BTU output to room size:

Small Rooms (up to 150 sq. ft.): A unit with approximately 2,500 BTUs works well.

Medium Rooms (150–400 sq. ft.): Look for models with about 4,000 to 5,000 BTUs, which is ideal for bedrooms and smaller living rooms.

Large Rooms (over 400 sq. ft.): Select a fireplace with 5,000 BTUs or more to ensure sufficient warmth.

It’s important to keep in mind that electric fireplaces function as supplementary heaters, so if you have a large space or live in a particularly cold climate, you may need additional heating support.

Step 3: Choose the Right Size by Room Type

Different rooms require different fireplace sizes, both in terms of heat output and design. Here’s a breakdown of ideal sizing by room type.

Living Room

The living room is often the largest space in the home and a central gathering place, so consider a statement fireplace that complements the room’s dimensions and layout. Wall-mounted or built-in electric fireplaces work well here, as they can be large and become the focal point of the room.

For a standard living room:

Recommended Size: 50 to 60 inches wide

BTU Output: Around 4,000–5,000 BTUs

English Units

English units were the units of measure used in England until the 1820s. From these units were derived the imperial unit system, still in use in the United Kingdom and Canada, although both these countries officially recognize the metric system as their unit of measure today. US customary units were also derived from English units and is still the official unit system in the United States, though many industries in the country, including the automobile industry, tend to use the metric system.

Both the imperial unit system and US customary units use inches, feet, yards, and miles as units of length, although the definition of these units was different until standardization in 1960. Liquid volumes use units of gallons, pints, and ounces, again differing between the two systems. Pounds are used for weight, pound force for forces, horsepower for power, and British thermal units (BTUs) for energy, among countless other units.
