<p>Doesn't all the heat used for cooking go into the living space
anyway (aside from any that gets stored chemically by the cooking
process)?</p>
<p>No doubt the difference is relevant for calculating the
performance of individual parts of the system, but does it make
any practical difference overall, if cooking is always done when
there is also a need for space heating?</p>
<p>But if the stove is ever used for cooking when there is no need
for space heating, wouldn't the inefficiency arising from that
fact alone far outweigh the inefficiencies in the "cooking" part
of the system?</p>
<p>Similar to what happens when you add a USB electric output to a
cooking stove, if people then start running the stove purely to
charge their devices.</p>

exchanger so whatever the cooking efficiency is (depends
on the power setting) that is subtracted from the space
heating efficiency. </div>
