Each year, as the cold season approaches, you find yourself torn between your environmental concerns and the need to properly heat your home.
On the one hand, you want to preserve the planet's natural resources and on the other, you want your home to remain a cozy nest in which to live, so that your whole family feels comfortable.
To reconcile the two while reducing your electricity bill, you can opt for an ecological heating system!
We offer four less energy-consuming solutions.
Wood pellets limit CO2
Provided it comes from forests that are managed in an eco-responsible way, wood can be used to heat your home while having a limited impact on the environment thanks to its carbon neutrality and its naturally renewable nature.
Among the most efficient wood-based heating systems, we find in particular the pellet or pellet stove.
Derived from unused sawmill residues, such as dust and shavings, the latter are more economical than fuel oil, gas or electricity and are considered even cleaner than logs, due to their more complete combustion.
As for the performance of the device itself, it is on average between 80 and 95% and this, by rejecting a minimum of particles in the outside air.
By opting for this mode of heating, you can finally hope to reduce your energy bill by up to 30%.
Geothermal energy, heat from the earth
Clean, reliable, emitting practically no greenhouse gases and relatively inexpensive, geothermal energy draws the calories naturally contained in the ground or underground water in order to produce the energy necessary for heating, cooling and the production of electricity. domestic hot water. This system works thanks to a water-water or ground-water heat pump in horizontal or vertical collection, coupled with buried sensors. The heat is then diffused in the house thanks to a heated floor or low temperature radiators.
If geothermal energy is today one of the most used energy sources in France, it is because in addition to being renewable, in the same way as wind or solar power, it does not depend on meteorological conditions, which allows it to generate heat and electricity available almost permanently, without producing waste.
Moreover, despite a fairly large initial investment (€20,000 on average installation included), its installation makes it possible to divide household energy bills by three, and thus save almost €2,300 per year.
It is therefore quickly profitable, especially if you take advantage of aid such as MaPrimeRenov' and energy bonuses.
Aerothermy in tune with the times
Drawing the calories contained in the outside air to heat the interior of dwellings, aerothermal air-air or air-water heat pumps are however the most widespread in France because of their multiple advantages: reversibility, profitability, performance and low environmental impact.
Their implementation is much easier and less expensive than that of geothermal heat pumps.
On the other hand, they are less efficient and often require additional heating during very cold periods (below 3°C), especially if you live in a region where the winters are particularly harsh.
Good to know: their installation is also eligible for aid such as MaPrimeRénov' and energy bonuses.
Solar, the sustainable choice
Source of natural heat if there is one, solar energy is the ideal solution for heating in an ecological way.
In addition to the photovoltaic panels on the roof, which can be coupled with a thermodynamic water heater, there are also specific bay windows which help to better retransmit the heat of the sun's rays in winter, especially if they face south.
If you are lucky enough to live in a region with a high rate of sunshine, it will be particularly advantageous to take advantage of this free and non-polluting source of energy!
