What you need to know about oil boilers

Compared with older installations, conventional (very) low temperature boilers offer the advantage of controlled operation depending on the outside temperature.

While old boilers must always be operated at a constantly high boiler water temperature (max 90 ° C), the boiler water temperature is regulated according to the outdoor temperature on Viessmann oil boilers.

A very low temperature boiler stops as soon as it is no longer necessary to produce heat.

A condensation:

The condensing boiler is a very high efficiency boiler, which allows energy recovery at the flue gas. The condensing boiler is a gas or oil boiler whose efficiency conforms to the condensation level according to Directive 92/42 EEC.

The fumes are cooled through an exchange, by the return of the heating water. The water vapor condenses and its latent heat of condensation is transferred to the return water, adding to the heat of combustion.

In addition, the flue gas temperature is reduced, which makes us achieve efficiencies greater than 100%

Gas boiler

A gas boiler is a boiler using gas as fuel, natural gas, propane or even butane. Depending on their layout, there will be gas boilers on the ground with a higher heat output than wall boilers, most of which are installed in kitchens or bathrooms.

The gas boiler is called single or double service depending on the case where the boiler produces heating or heating and hot water.

The most economical gas boiler is the gas condensing boiler.

The recovery of the energy of the fumes, allows the gas boiler to reach yields up to 107%. The lower the hot water temperature (<50 °), the higher the efficiency of the condensing gas boiler.

Boiler heat pump

(Thermodynamic water heaters)

A thermodynamic boiler can be installed in both new construction and renovation projects. Using heat (free) from the air - ambient or outside air - the unit can heat X liters of water and store them in an enameled steel tank.

Even when the outside temperature reaches -7 ° C, the unit does its job without problems and heats the water up to 60 ° C, without additional heating system.

Heat pump

Free energy of the environment

A heat pump uses the free heat that exists in nature. The heat pump is a reverse cycle refrigerator.

A heat pump operates according to a cyclical process in which low temperature heat (= free in the air) evaporates a liquid (= refrigerant) after compression of the gas by the compressor.

As a result, the pressure and temperature increase. Once at the indoor unit, the hot gas is condensed and releases heat to air or water.

The new houses are ideal for the integration of these heat pumps with dual functionality. In renovation projects, a thorough analysis of the situation is required, but there are few arguments against the heat pump

Hot water accumulator

The hot water accumulator is a reservoir of X liter of water that once at the requested temperature supplied the house with hot water.

The accumulator can be heated by electric current or by a boiler.

Floor heating

The advantages of underfloor heating

The underfloor heating is a system used both in renovation and new construction, are pipes placed in a screed on a given surface.

The water temperature varies from 21 ° to 35 ° + - (low temperature) and this heat discharged into the screed is deployed uniformly throughout the room concerned

Solar panels

The solar thermal panel is a device recovering the energy of sunlight to transform it into heat, transmitted to a coolant.

Description of a solar thermal panel

Panels or tubes under vacuum in which circulates a heat transfer fluid, this passing is heated by the rays of the sun.

Using the solar thermal panel

Water thermal panels can be used to heat sanitary water or as auxiliary heating.

The low temperature boiler

In comparison with a conventional gas boiler, low temperature boilers offer a more pleasant thermal environment and can save around 12 to 15%.

The main advantage of low temperature gas boilers lies in their ability to use water at a much lower temperature than traditional gas boilers, down to 40 °.

Modern, its internal components are of high quality, so that its technology protects it from corrosion. It is therefore intended for a better life expectancy than its predecessors.

This type of gas boiler regulates the temperature according to the actual energy demand.

Therefore, heating adjusts its intensity according to the heating needs of each building, considering many factors such as heat loss, location or orientation of the building.

Low temperature boiler: how does it work?

If the outside temperature is cold, the heat generated by the boiler will be high. If, on the other hand, the outside temperature increases, it will decrease until the minimum limit is reached.

As its technology allows it to adjust to the outside temperature, it does not need to be constantly running.

The heat produced is then used to the maximum and the losses, greenhouse gas emissions and consumption are considerably reduced.

Low temperature boiler: what are the advantages?

·        It can generate savings of more than 12% compared to a conventional gas boiler.

·        It regulates its temperature according to the energy demand.

·        It is preserved from corrosion.

·        It can be an intermediate solution between conventional gas boilers and condensing boilers.

Low temperature boiler: what are the disadvantages?

·        The prices of a low temperature gas boiler far exceed those of a conventional gas boiler and can range from 3,000 to 7,000 €.

·        The energy requirements set by the European Eco-design Directive of 2015 aiming at eliminating harmful environmental heating systems from the market set a minimum efficiency of 86% for boilers. Not only are the aids for replacing your current boiler with a low temperature boiler are obsolete, but some low temperature boilers are no longer allowed for individual homes. We understand that low temperature gas boilers have an unsurprising future...

·        In order to maximize energy efficiency and efficiency, the low temperature boiler must be connected to low temperature radiators. Its installation may therefore involve the replacement of the entire heating system.

·        Unlike a pellet boiler that uses wood for fuel, the gas boiler burns a fossil fuel that is destined to disappear and whose costs fluctuate very unpredictably.
