Boat Water Heater

[johnkelly1]

I have a Seaward F600 Water Heater fitted in my boat and a pressurised system.
The water is heated via the engine calorifier and after a 2 hr trip hot water is being discharged into the bilge via the T&P valve.
Has anyone any idea on what may be causig this?

The water will expand as it gets hot, that's what the pressure relief valve is for.

the only fix I've come up with for this si to fit a Jabsco accumulator tank AFTER the hot water tank.

The pressure relief valve may have got crudded up, give it a twist and see if it will reset, but I doubt it.

Think you'll need a new one.

Many thanks. I will give it a go.
I actually purcgased the 2 Thermostats then realised they will only operate when using the electrical element !!
