Just wondered whether to put water permanently through my fogwash, or have any of you put a shut off valve to divert water away from your heater when its not needed?
Any descriptions and products used would be appreciated.

It's quite simple, before the heater (after pump, DI) insert a 13mm y piece, after the y piece two valves. One end of hose goes to the heater, back out of the heater and back into a y piece. The other hose from the first y piece joins up to this. Close one valve, open the other and you have hot and vice versa for cold. A picture says a thousand words, but I don't have one handy.
