Isolate hot water tank from engine coolant?

[Sulaire]

Hi

Our hot water tank is right under our bunk, and as such when we motor anywhere, the heat build up in the cabin is significant. We cruise in hot climates anyway so this extra radiated heat is not welcome.

I have lagged the heater with foam to try and keep the radiated heat down, but not enough.

Has anyone fitted a simple stop valve in their engine coolant pipe that feeds the water heater, to stop the coolant from ever getting to the hot water tank? This way we can control if we want hot water or not!

I cannot think of any problems, but just incase.....

Thanks in advance

Three re are no issues with that idea as the cylinder is usually In parallel to the existing engine circuit
