Hi All,
I'm thinking through a winter project to add hot water to my boat and your collective thoughts on a system are appreciated.
I'm a day sailer/marina hopper, come weekend bolthole type of sailor. I don't need off multiple redundant offshore independent systems. I just want a small hot water system to feed the galley sink for washing up the tea cups, the heads sink for lick and a promise before the pub and a cockpit shower on those (very) occasional summer swim days.
My boat has a Yanmar 1GM10 engine and as it's directly sea water cooled it's not really suitable for setting up a calorifier. I know there are kits for fresh water cooling a 1GM10 but they are a bit over the top for my needs.
I'm really happy to have a small, shore power only 1KW or so, immersion heater tank of around 16 litres such as the Isotemp Slim Square. However, it's a bit expensive and complicated given I'm not going to use the engine water calorifier connections (I'm imagining just tapping them off if necessary). I don't want an instant electric water heater as it won't store any warm water on passage. As such, does anyone know of a small, simple, immersion type heater tank for the marine environment? A custom tank producer?
Is there a better, off the shelf product or solution that I'm missing out on?
Many thanks
