Using hydrogen for domestic heating is a very bad idea

Using hydrogen for domestic heating is a very bad idea. It is much more efficient to heat houses with heat pumps compared to heating with hydrogen. Don't you believe?

With heat pumps, you can heat six houses instead of one house heated with green hydrogen when the same amount of renewable electricity is used. For heat pumps, a coefficient of performance (COP) = ~3 is assumed. The COP value of 3 means that you get ~3 kWh of heat output for every 1 kWh of electricity used to run the pump. The result can be seen in the picture below.
