hot water flowing into expansion tank
Posted by mick o driscoll on October 01, 19100 at 07:47:33:
I have a pumped hot water system,and when the boiler and pump are on the hot water flows out the expansion pipe into the tank.IE.the tank, which is the highest part of the installation, seems to be behaving like a radiator.Also the water in the expansion tank gets very hot through the feed pipe from it to the heating system.Please help.
