Reply To: Hot water system

I too sort to minimalise the amount of gás systems on board. I put in a completely new set up for the cooker. In the gás locker is fitted with a bubble leak Checker and also a automatic bottle change over valve which switches to the full bottle when the 'in use' bottle is emptied. Also fitted a gás alarm with sensors both under the floor in the galley and in the forward water tank cupboard between the galley and gas locker. Alarm has solinoid in the locker to suit off supply if alarm is activated. Manual shut off valve at the cooker for belts and braces.
I would think it would be difficult to use a balancing pipe for tanks as they are lower than the saloon floor and forward deck lockers too. I chose the route of a three way valve in the heads and jualsowitch from one tank to the other as needed, also helps with keeping tabs on how much is left ;).. The water pump also is fitted in the heads with calorifier, the engines on the HT are too small to give off enough got water to make use of in the calorifier, went for this option as if needed i could add a small eberspacher water heater like found on a lot of vehicles as an deisel option later if required. So far the electric option has worked great we do on occation use the inverter to heat a tank of water at sew while running the engine to keep the batteries topped up. Electrical system is a whole other thread :).
