In one hour the hot exhaust gases from a 2.4hp petrol engine coupled to a 1kva generator raised the temperature of 20litres of water in a steel gerry can from cool to touch to warm. The gerry can was placed about 30mm from the exhaust, narrow side on, with an insulating rectangle of thick cardboard between the ground and the gerry can. I realize there will be variables according to volumes and ground and air temperatures. Happy Days.

Oldbaz, I picture the 240v outlet taken up with a surge protected power board passing current to a battery charger or other electrical creature comforts and lights. When the gennie is shut down in consideration of others peace and quiet the battery can be used to power the 12v shower pump and inverter powered lights and entertainment. While you are sitting back yakking annd snacking and the battery is being recharged, your bath water is being warmed by waste heat from the gennie exhaust. Happy Days.

My old LWB Holden powered Landrover Series 1 had a 20 litre hot water tank that was heated by a copper heat exchanger that the exhaust passed through. I t circulated by convection and at the end of the day supplied hot water for all purposes.

guy007, would not surprise me to see this system reappear in the next generation of true offroaders, now that you have brought the idea to the fore. Happy Days.
