perhaps he talked to the rong retard.

you seem to be doubting established physics, my good man. it isn't hard
to concoct an example to prove you wrong. if the house conductance is
1000 btu/h-f, 50k btu/h will make it 60 f inside when it's 10 f outside,
and 49k btu/h will make it 59. add a 307.7 pound standard ashrae cow or
25.497 standard bunnies, and we are back to 60 f.

this comment was also directed to you, not him. "comfort," eg "warmth"
is quite real to some ahsrae folk.
