how to replace your gas boiler in an apartment?

As with any device related to your thermal comfort, such as air conditioning, ventilation or a water heater, it is important to think about changing your boiler. It is better not to be sentimental and to know how to part with it before it shows signs of an imminent definitive breakdown. The question then arises, what equipment to choose for those who live in a building ? Through his Podcast Chaleur Humaine, The world tried to provide some answers.

Our colleagues first remind us that before thinking about changing your heating method, it is advisable to undertake energy renovation work and to properly insulate your home. The goal: to consume less energy, therefore reducing your greenhouse gas emissions – and, ultimately, reduce your bills. Once you have made progress on this ground, you can ask yourself the question of the heating method. In individual houses, the simplest is often to switch to a heat pump, an expensive investment but which has advantages: the energy consumption of the heat pump is low and the greenhouse gas emissions are very low.

Obtain the agreement of the co-ownership

In condominium buildings, if the heating is central, it is sometimes possible to get connected to a heating network, emitting few greenhouse gases. But not all cities have them, and this requires work as well as the agreement of the co-ownership. Installing a heat pump in an individual home is certainly possible but poses major technical difficulties. For example, the structure of old buildings is not very suitable for the deployment of this technology. What is more, here too, you must have the agreement of the co-ownership, which is far from being a given.

Finally, the final option consists of investing in electric inertia radiators and a hot water tank to return to electricity, but be careful, the work is often expensive. You must be careful to choose energy-efficient radiators and not old “toasters”, which consume a lot. If none of these options work, Ademe then recommends opting for a high energy performance gas boiler, which can save money. 20% to 30% energy.
