The message
from The Natural Philosopher contains these words:
Also bolers are more effcient at lower temps I THINK. Not sure ..
They should be. You can't transfer energy so easily into a warm body
from a hot one as you can into a cool body from a hot one.
Also with lower return temps a condensing boiler should be able to
recover more of the latent heat of vaporisation, getting ever closer to
the gross energy content of the gas burnt.
