Thanks for reading.
I have two questions related to heat transfer.
a) How does heat loss work. For example, is it inverse square law, like
RF losses. Or linear, or what ?
b) I have a two boilers. One is 10 times bigger than the other. Do I
simply need 10 times the power (kilowatts) *to raise the water to the
same temperature ?*
