Heat from heating pipe?
is it possible to derivate the heat of the heating pipe of an heater to make a water circle (with a pump) to create ones own heater?
Because i feel the heating pipe is extremely hot and it's heat for free, so why not using it?
The idea is to build something like a water cooling system for the PC but just without the cooling.
Can i wrap a cooper pipe around the heating pipe and let water circle with a pump, so the hot water passes through the "new heater". I dont know what to use as heating object but there will be a way.
Any ideas? Is it even possible?
Thank you and sorry for my English :D
