That is a gross mis interpretation of what I wrote: it is a luxury
good because of its price-demand  and people like looking at a flaming
fire. Because it is chopped up and delivered in small quantities it
works out  far more expensive than the "normal" fuels which in London
are likely to be gas and elctricity. In the circumstance of a
centrally heated dwelling who use an open fire the fire is likely to
eject more heat from the room up the chimney than it puts into the
room (largely by radiation).

It's a good point, capital cost verses reduced running costs, and my
gas boiler (a non condensing type) is over 20 years old, a replacement
should convert more of the energy in the gas to heat for the wet
system but would take about 15 years to recoup and I very much doubt a
modern boiler will last that long.
