Underfloor heating, gas boiler, aerothermal… What is the best heating system?

With the arrival of the cold and the heaters running at full capacityIt is time to check if the installation we have at home is really efficient without excessively damaging our economy.

Heating systems have evolved significantly in recent years, pursuing a double objective: be more effective at the time of obtaining higher energy performance that contributes to caring for the environment and, incidentally, your pocketbook.

Most used heating systems: pros and cons

Among the systems that require prior installation there are several. The most used in recent decades have been those that demand a certain fuel as an energy source (natural gas, propane or diesel) and those that use electricity as a raw material basic.

In the first group stands out, as a valid system for almost any home, the one made up of one of the current condensing boilers, to which are added the necessary radiators that air-condition the house. Many of these boilers use natural gas to reach the ideal temperature in the home and provide hot water.

The Organization of Consumers and Users (OCU @consumers) highlights of these teams their high calorific efficiency, its low pollutant level and its energy efficiency. Natural gas is a good option (as long as there is a supply in your place of residence), although its main drawback is the cost of the boiler and the periodic reviews that it must undergo (generally once a year) to guarantee its optimal operation.

The heating by diesel works similarly, but requires a deposit that you will have to fill every so often to have fuel. It is usually used in large houses, country houses or farms, since the tank occupies a considerable space.

Radiators can also be heated by propane, a gas channeled in some areas, but that can also be supplied in tanks or in cylinders similar to those of butane.

Radiant wire heating system

The evolution of underfloor heating

It is another heating system that is back on trend, since in the past it was considered an inefficient and rather expensive air conditioning method. The underfloor heating that is installed today has little to do with that of the nineties. The system consists of place under the pavement a series of fine pipes that will be responsible for heating up and emitting heat to the point of exceeding the floor itself, thus heating up any room.

Years ago it was the own heating cables or wire, suitably covered, which were fixed to the ground for the transmission of heat, but now what is installed are fine pipes through which water circulates, in the same way that it happens in radiators. It is the hot water that is responsible for generating the necessary heat for air conditioning. What’s more, your power supply may not just be electricity, but any other system that allows heating the circuit (gas boiler, heat pump, biomass boiler, solar energy …).

This heating it is perfect for houses not too big in which the radiators occupy a specific space. In addition, the current system is very effective since, as indicated by the Association of Manufacturers of Generators and Heat Emitters (FEGECA), the underfloor heating provides maximum comfort, because it can be installed on the floor or walls in a uniform way, achieving a homogeneous temperature. Furthermore, it is efficient because the temperature that the water has to reach to heat is lower than that required by traditional radiators. Also serves as a cooling system, if what circulates through the pipes is cold water.

Aerothermal heating system

Heat pumps and aerothermal

We are before two of the newest methods air conditioning in homes. Heat pumps are a system of duct heating and cooling, which require an outdoor unit and an indoor unit (there can be two depending on the surface). They serve to give heat in winter and fresh air in summer and work by connection to the electrical network.

The current equipment allows a significant energy savings, although its efficiency varies from one model to another. In general, they are advisable for homes that are not located in regions of extreme cold. In addition, it is important to choose a model that has a good Energy Rating (TO).

As an innovative system, still little known in our country, we must speak of the aerothermal heating. Simply explained, this technology allows capture the energy contained in the air around us and be able to take advantage of it to heat or cool a home. Although it sounds a bit strange, there are many who suggest that this could be the heating of the future.

How it works requires an outdoor unit, something bigger than that of an air conditioner, which “traps” the energy; a thermodynamic circuit or heat pump, and a output system of that energy, which can be radiators or underfloor heating, for example. The success of the system lies in its ability to capture much more energy than it consumes. As a drawback, the installation of this equipment, for now, supposes a high financial outlayBut, without a doubt, the idea of ​​harnessing the energy of the air itself sounds good.
