The installation of new boilers emitting more than 300 g of CO2 per kilowatt hour has been prohibited since Friday July 1. Oil-fired boilers still equip one house in six. Their owners will be able to continue to use them but in the event of an unrepairable breakdown, the heating mode will have to be changed, except in very exceptional cases. The government would like these domestic fuel oil (or coal, for that matter) boilers to be replaced by less polluting appliances by 2030 because the figures are clear: heating a 100 m2 house for one year with a heating oil corresponds to 50 000 kilometers in a thermal car in terms of CO2 emissions. While one year of gas heating (which remains a fossil fuel) corresponds rather to 30 000 or 35,000 kilometers.

The alternatives for those who will have to replace their oil boiler are four in number: gas, biofuel (which contains 30% of rapeseed oil derivative), wood heating and heat pump. But for the Negawatt association, if we want to invest in a virtuous and sustainable way in favor of the environment, we should rather choose between a heat pump and wood heating. The heat pump indeed emits seven times less CO2 than a gas boiler explains Olivier Sidler, one of Negawatt’s spokespersons (compared to fuel oil, it’s ten times less, it’s 5,000 kilometers by car instead of 50 000) and wood or wood pellet heating emits nine times less CO2 than gas heating.
The impact on a household’s budget is substantial. Changing the boiler is an investment because installing a heat pump, for example, costs around 10 000 euros is twice as expensive as installing an oil-fired boiler, but there are aids such as Ma Prime Rénov’. And moreover, the savings are then made on the heating bill, in the long term, especially if the insulation of the accommodation is reinforced. Over the year, fuel oil costs at least two to three times more than the other heating methods that we have just mentioned.
