What is the best type of heating to improve my DPE note?

You can change the windows, isolate your ceiling, put a new coating … but if you miss your heating system, Your note DPE will remain scarce. Often it is this technical detail that attenuates the ambitious renovations. And the question that returns to a cycle is always the same: What is the best type of heating to improve my DPE?

DPE: Why does heating weigh so much?

The diagnosis of energy performance is based on two pillars: annual consumption of energy energy and greenhouse emissions. Now this is the heating which is the greatest collaborator. A scarcely sized radiator, a dilapidated boiler or a system that consumes energy and find yourself in class F also g, with all the consequences that this implies.

The impact is double. First on Resale value : Poorly classified accommodation. So on renovation aid: some subsidies become inaccessible if the DPE gain is not enough. That’s why the choice of the right thermal equipment is not just a matter of comfort, but Energy efficiency overall homes.

It is not a simple technical decision. It is a strategic lever. And it’s exactly where everything takes place.

The system that really changes the situation

All professionals will tell you: The heat pump is today the most efficient system To improve a DPE. His yield, called Cop, often exceeds 4. This means that with 1 kWh of electricity, it produces 4 in heat. Result? Consumption that collapses and CO₂ emissions close to zero, especially if you have green energy.

This choice remains expensive for the installation, but is enormously supported by the state. And above all, it can make you Win two to three classes On your PC. It is one of the few solutions that really transforms the energy profile of accommodation. However, this is not a universal response.

Other solutions, such as pellet boiler or sun heating, can be more suitable for certain configurations, especially in rural areas or old houses. It all depends on yours Energy auditthe surface to be heated and the level of thermal insulation already in place.

The systems to avoid if you keep your DPE

The myth of «Alla Electric» has left traces. Many accommodations from the 80s to 2000 are still equipped with convection radiators. These famous «toaster» show enormous consumption for uncomfortable heat. They literally lead the DPE and place your property in the category of thermal coffers.

Another trap: fioul boilers. Same efficient on paper, are massively sanctioned by the new DPE grids due to theirs High carbon emissions. At the time of energy transitionContinuing to invest in this type of equipment imported to throw money from the windows. Do not hesitate to compare the citations before starting.

Even condensing gas boilers, however effective in consumption, undergo a carbon penalty. They remain a wisdom, often installed for lack of better, especially for budget reasons. But they do not offer a real exclusive movement at the environmental level.

The choice depends (also) on what you have already done

A heating, however efficient, will not make a miracle in a thermal colander. Before thinking about the heat pump or granules, ask only one question: Is your accommodation correctly isolated? This is often where thousands of euros in scarcely targeted renovation.

A coherent project always begins with a Renewal of global energywith a priority on the envelope of the building. Once the isolation of the attic, the walls and the floor made, the change of heating takes on its full meaning. It is this duo that triggers the most spectacular DPE gains.

In some cases, the addition of a double -flow VMC or an intelligent regulation system opens even the final score. A DPE is not a frozen test. Reflects the harmony between the different positions of the accommodation. And it is this harmony that makes the difference between a simple update and a real increase.

My opinion: not to be confused for the priority

You undoubtedly felt this sentence: «» The best heating for the DPE is the one that consumes the minimum «». It is true … and totally insufficient. The ideal heating is what It integrates into a coherent energy strategyDesigned for several years and not as an energy painting blow before selling.

Because only changing the boiler without thinking about isolation, it’s like putting a judicial proceeding on a soaked floor. You will have spent without really improving. And you will miss real help, real earnings and true comfort.
