Wooden house heat fireplace of auxiliary pump

Wooden house, heat, fireplace of auxiliary pump. There is more than the electric car to Marguerite Bouvier to fill all the boxes of the Grenelle of the environment. A year after his move to Poltrot in Yvelines, this ex-Parisienne has not regrets his choice. "Our energy bill is the same for 200 m2 today as our former Parisian apartment of 70 m 2, which was heated gas", tells the designer.

Gas, electricity and fuel are still dominant in homes, the French move to cleaner modes of heating. According to the latest figures from the Ministry of ecology and energy, about a third of the individuals who received permission to build a single House in 2007 have opted for a heating using renewable energy sources: geothermal energy, photovoltaic, heat pumps, wood heating.

Since then, the trend is confirmed. Sales of heat pumps, taking the calories in the air, exploded from 51,000 to 133.000 between 2007 and 2008. This year, the market should fall back to some 80,000 machines. "It is the result of a phenomenon of clearance, but also a sign that the market becomes mature," said David Bonnet, Vice-President of the Union professional APMA and commercial Director of Technibel France.

Wood, continues its renaissance. This year, it should sell about 500,000 heating wood (fireplace, insert, stove, boiler), or as much as the year last and 200,000 more than in 2004, according to the Union of renewable energy. "Heating pleasure gave way to a mode of heating, economic, efficient and clean", explained Frédéric Coirier, President of Poujoulat, chimney ducts specialist.

Economic benefit of gas

These heaters are important fiscal aid. But these sectors coming to maturity, they declined. Under the Act of finance 2010, heat pump tax credit must be reduced from 40 to 25. For an investment of 8,000 to 24,000 euros depending on the model, it counts. Ditto for the wood stove, which can range from 500 to 10,000 euros.

So far, this development has not too embarrassed Affairs of EDF. Electricity remains a mode of heating very appreciated by France. About one-third of homes are equipped with in and, in 2007, nearly half of new owners of houses still made that choice. The campaign "Vivrélec", launched by EDF more than ten years ago to promote electric heating in France, is still bearing fruit.

Gas, energy market leader, plays on his side on his economic advantage to defend its position, as the fuel. "The carbon tax will have an impact, but heating with gas remain cheaper, says Henri Ducré, in charge of the energy France in GDF Suez branch." For an existing individual House 110 m2, heating and hot water gas is approximately 1,000 euros TTC per year, against about 1,500 euros TTC for electricity.

For Greenpeace, the electron is little better than gas. Based on the work of the bureau to study ICE, the ecological Organization estimates that the average content of electric heating in France carbon dioxide rises to 226 grams of CO2/kWh, against 205 g for gas heating. Why Because it involves ways to production strongly emitters of greenhouse gases, like coal, to meet the needs of advanced in winter. Emilie Johann, of Greenpeace, to focus on the insulation and energy efficiency.
