Ex Machina 384 Posted January 29, 2023 Share Posted January 29, 2023 I’ve been Looking at ducted exhaust LPG water heaters like the suburban and camec style etc . Anyone here got one of these ? And do you have the tankless or tank version ? The fitting options seem more flexible than a classic style califont and probably easier to meet certification criteria too.

Bad Kitty 287 Posted January 30, 2023 Share Posted January 30, 2023 Have you looked at Eberspacher diesel ones? They also do a tank version or one that uses a normal type water cylinder. Quote Link to post Share on other sites

The boat has a heat exchanger type tank that’s only configured for shore power so could be plumbed in to a diesel heater I think . Quote Link to post Share on other sites
Bad Kitty 287 Posted January 30, 2023 Share Posted January 30, 2023 Our one is like that, 20 ltr cylinder that will run off the genset or shore power using the element, and with the Eberspacher pumping hot glycol thru cylinder like an engine heat exchanger.

LBD 170 Posted February 6, 2023 Share Posted February 6, 2023 Just had a survey completed.... inboard gas califont was not viewed favorably and the insurer wants it gone. Will replace it with an engine coolant heated 30L cylinder Quote Link to post Share on other sites
strath 4 Posted February 6, 2023 Share Posted February 6, 2023 Where can you buy a 10L engine coolant heated marine cylinder? without the electronics. Quote Link to post Share on other sites
ballystick 79 Posted February 7, 2023 Share Posted February 7, 2023 Fridgetech have a slimline 16 litre hot water cylinderhttps://www.fridgetech.co.nz/collections/isotemp-water-heaters/products/slim-square-16 Quote Link to post Share on other sites
CarpeDiem 510 Posted February 7, 2023 Share Posted February 7, 2023 The thought of a leak of coolant into the fresh water inside the cylinder really scares me. Coolant is lethal in small doses, 80mls and you're done for. Perhaps I am over thinking it as I have never heard of this happening - but it's not like I have never heard of corrosion on a boat happening!!! Hence the over thinking We used to have a cylinder that was heated off the salt water circuit, but that was with a raw water cooled engine. I am not sure if the salt water side of modern engines with coolant/raw heat exchangers would get warm enough? I still have the cylinder if anyone wants it, it was "made by" Volvo Penta and was part of the 2003 series engine kits. I disconnected/removed it from the boat when we repowered the engine as I didn't want to risk any residual salt water getting into the new ethylene coolant circuit.

strath 4 Posted February 14, 2023 Share Posted February 14, 2023 Hi CarpeDiem I would like to have alook at the cyinder for heating water, is it possible to post a picture of it. Thanks Strath Quote Link to post Share on other sites
