	Why would anyone put a "refrigerant coil" in a "Hot Water" heater? Could you share your application --- we won't tell anyone we promise.

	Use a UK domestic copper immersion cylinder with a coil for an external heat source like a central heating boiler, and pass a cold utility fluid through the coil. B&Q or Wickes keep them in stock <usual disclaimer>. Beware the pressure rating of <0.5barg on the cylinder. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	No The new heat pumps use a scroll pump and variable speed DC motor. The mini-split systems divide the house into zones and pump only what is needed. the hot water heater is a zone, cutting the electricity needed by up to 70%. I still need a name __________________ Archers arrows

	Coils in tanks are so inefficient,a brazed plate heat exchanger with water one side and the other acting as the condenser would be far better.
