Reply To: Hot water system

Dave, You can use a gas water heater just to heat water, but there are regulations about sealing any places where pipes come through any bulkheads. Also regs about venting any CO2 out of the boat (for safety reasons).

As Salty says you can use a calorifier run off the engine, but that usually is fresh water cooled variety, not raw water as yours is. You could fairly simply put in a tank with an immersion heater and a pressurised pump system to pump it to the heads and galley. Are you going to use it mostly in marinas on 240v or will it need to be 12v? Loads of choices and prices to choose from.
