I want to convert a Water Heater to a holding tank and use my boiler hot water tank to make the hot water. I have been told some companies make an exchange tube to insert into the Water Heater. I think this is to prevent back flow into the cold water side of the tank. Can this be possible or is this all hot water

Thx

Danny,  
A good number of boiler mfg. make heat exchangers for their boilers, to make the domestic hot water. Check with your boiler mfg. first.
