Heating: the 6 ways to lower the note with use.

Heating devours an ever increasing share of the family budget. On its own, it accounts for about 65% of all energy costs in the home. What can be done to reduce your heating bill? With simple gestures and improvements, you can limit your energy consumption without losing comfort. There is also competition between energy suppliers.

We spend about 6 months a year with the heating on. This is the heating period. A moment that many apprehend so much the bill that follows is heavy. To limit the soaring of the heating note, we can adopt good behavior: to maintain the installation, close the shutters, program the heating room by room ... On the other hand, if we aim for a significant reduction of the bill, it will be necessary to go through improvement work, including insulation.

1. Insulate the house to reduce the heating bill

A well insulated home retains the heat. Heating needs are decreasing and comfort is increasing. As the heat escapes first through the roof, then through the walls, one will isolate in this order of priority. The implementation of roof insulation varies according to the use of the attic. For lost roof spaces, floor insulation is the most effective. For converted attics, different insulators exist in semi-rigid panels, rolls or even in bulk. Always be careful to ensure proper ventilation of the cover.

To insulate the walls you can proceed from the inside or the outside. Outdoor insulation is the most efficient, it greatly improves the overall thermal performance of the building. Additional benefits: there is no loss of surface and you do not have to move during the work. On the other hand, it is more expensive.

Do not hesitate to invest in insulation, you get for this public aid: VAT to 5.5%, the tax credit for energy transition and eco-PTZ.

2. Changing the boiler or replacing old convectors lowers the heating rate

For many years, boiler and radiator manufacturers have focused on energy efficiency. The equipment has become ultra-efficient. If your boiler is over 15 years old, ask yourself about its replacement. For example, switching to condensation results in a saving of between 15 and 20% in energy consumption. Public aid is there to facilitate investment.

On the side of electric radiators, here too, the technical evolution has been considerable. Do not hesitate to replace your old toasters with radiators with inertia. They are equipped with a "heating core" (ceramic, cast iron, coolant) which accumulates heat and restores it. With such radiators, equipped with programmers, the economy can reach up to 45% of the amount of the electricity bill. You will also notice a radical change in comfort, the heat is soft, homogeneous and stable.

3. Heating circuit maintenance saves money

You have a well insulated house and your equipment is relatively new. Do not overlook the regular maintenance of the heating circuit, it is a significant source of savings. Every year, have the maintenance visit of the boiler to dust it and check the state of wear of the parts.

Every 5 years, outside the heating period, ask your professional to disembowel the heated floor or rinse the water radiators. The mud acts as insulation and degrades the performance of the systems. It is also the cause of thermal discomfort as it reduces the flow of water.

You can, yourself, adopt good reflexes when warming up: dust off your radiators, check that they heat homogeneously (without cold zone) and that they do not leak. If you notice a cold zone, purge your radiators to vent the circuit. It is a simple manipulation but take precautions because the water is very hot. The radiator is properly purged when the stream of water that flows is regular. Then remember to put water in the circuit at the boiler.

4. No heating economy without thermostat

The big provider of savings is the thermostat. Instead of heating continuously, all day, you will adapt the heating to your needs, thanks to the regulation. ADEME estimates that good management saves around 10% on the energy bill.

Start by installing a room thermostat. Place it in the living room and program scenarios according to your needs: day, night, weekend. Some thermostats are remotely controllable via smartphone or tablet and provide you with accurate dashboards of your consumptions. Very interesting if you want to be a player in its energy consumption. For a high-performance thermostat, allow between € 200 and € 300 excluding installation, this type of equipment is eligible for the energy premium and benefits from the 5.5% VAT.

Then, for room-by-room control, install thermostatic heads on your radiators. Finally, the outdoor sensor is also a good option if you are in a detached house. For example, it allows the temperature of the hot water to be adjusted according to the outside temperature. In the heart of summer, you do not necessarily need or want a hot water.

5. Good reflexes to not pay too much heating

Simple but effective actions will help you not to consume too much energy. Check that the window seals are in good condition, otherwise replace them. In winter, close shutters as soon as it is dark. Close the radiators when you ventilate the house. Check that the cold air does not pass under the landing door, otherwise install a door sill or a broom. Put the house in winter outfit with carpets and thick curtains. Finally, clear the radiators so that the heat diffuses into the room.

Do not overheat. The recommendations of the ADEME are 19 ° C in living rooms and 16 ° C in bedrooms. 1 ° C more, it's 7% more energy consumption. If, however, you feel the cold at these temperature levels, it may be that the house is wet. Moisture accentuates the sensation of cold. Avoid drying clothes in the living area and, if necessary, equip with moisture absorbers, they are very effective. A tip if you are absent: if your absence is less than 48h, lower the temperature to 16 ° C, if you leave more than 48h, switch to frost protection mode.

6. Buy your energy cheaper

The price of energy is the heart of the problem. The energy consumption of the French does not increase, it is the price of energy that gallops. Despite the liberalization of the energy market, very few households have opted for alternative suppliers. They are 17% for gas and just 10% for electricity. Can we really talk about a competitive market?

However, in this area as in others, we must not hesitate to play the competition. You are free to change your energy provider at any time without penalty. Do not rely on highly touted but limited promotional offers, always compare a total price including tax (including subscription and consumption). To help you, you can use online comparators.

Group purchasing is changing the game in terms of energy purchase, as the UFC-Que Choisir's "Less expensive gas" campaign launched in 2014 and renewed in 2015. 60,000 households benefited, in early 2015, from a contract negotiated by the association, realizing on average 13% savings on their purchases of gas.

To master them well, learn about your energy expenses. How much energy do you consume per year, in kWh? If your bill increases, is your consumption increasing or only a price effect? What is the share of heating in your energy expenditure? With these indicators, you will more easily make the right decisions.
