This is exactly what I want to try,
My electric element will heat the water up to a certain temp( 25-30 degrees c, and the boiler takes it up to 60-70 degrees c, thus reducing oil usage.
Thanks Zoobie,
Another way of asking my question is:
If i heat a temp transfer liquid eg oil and run this through a exchanger to heat water, will it take less energy to heat the water in this way than to heat the water directly.
My heat source is 300watt DC elements,supplied from a wind...
I want to build a heat exchanger for use in a house.
My source of heat is quiet low, my aim. is to try to come up with a heat exchange to heat the water in the heating system.
What liquid could I use to bring the water up to a decent temp in a heat exchanger.
Is this possible or am i mad?
