Oxygen boilers – making condensing boilers more efficient
A condensing boiler is more efficient because it recovers some of the latent heat from the hot water vapour in the flue gas. However, no domestic condensing boiler manages to condense all the water…

Yup, here is the efficiency curve (maximum theoretical) for condensing v non-condensing

I did a thing - which illustrates how useful AI can be in creating small models, in this case, the theoretical maximum COP for a heat pump:

bio oils sold for heating are an uncontrolled market: rife with possibilities for adulteration with cheaper fossil oil. No chain of custody or reliable certification process. The mere fact that the program exists will tempt some not to replace their oil heating with a heat pump, which would be Bad.

Is it finally going to address the biomethane leak monitoring issue? Or the designed-in CH4 emissions in the separation stage?

Hydrogen is now extremely dead, as the Government reveals in the modelling annex it has not even bothered to model it. /7

That is an extremely long, extremely confused article. I cant even work out what it is in favour of, and what it is arguing against. Can you point me to a clear summary?
