I am going to build my house with the new RT2012 standards. The heating system will be a PAC Atlantic air / water 6kw. My builder announces a heating consumption of 100 euros per year. I am a little skeptical. Thank you for your reply

There is theory and reality. It is true that a house built in compliance with the criteria of RT 2012 requires very low heating requirements and that a CAP can be very economical. But we must also take into account the way of life. Few people get warm at 19° C, the reference temperature for consumption calculations. The ventilation mode of housing (often open windows or not?), Also affects consumption. It is also necessary to add the domestic hot water consumption, which can exceed the heating costs in a house RT 2012. Starting from 300 to 400 euros per year, including domestic hot water, seems already more realistic.
