Insulation Insulation Insulation , Has to be dealt with first . Country wide overview not sufficient to evaluate actual efficiency . "In the real world" need to understand heat loss (and air leakage )and implications on heating system and costs .
As always, hydrogen in heating is never going to happen. It's intrinsically unsafe in a domestic property environment. Can you also explain how any gas boiler is 99% efficient? That's simply impossible surely. Where do those numbers come from?
