Hullo,
Our boat came with an Alde 2928 boiler - from reading the forums, they're terribly inefficient, very expensive and prone to breakdowns. Never mind all that, ours doesn't even turn on, so we'll rip it out and replace it with an alternative setup.
Before I go and spend a few £££ on a replacement system I thought it'd be best to run it past some people who know a thing or two - for hot water I'm thinking an immersion heater (we'll be on shoreline 95% of the time), and for heating I'd install a hobbit stove, with a back boiler. There's a radiator system installed at the mo , but they're not gravity fed and I've read enough warnings about exploding hot water to know it'll be a bit more complicated than just connecting the two together. Will just one gravity-fed rad work as a heatsink, or will they all have to be replaced? Or could we get away with no radiators at all? I've been seeing this thing called an 'ecofan' mentioned, apparently they're very good indeed...
Cheers
Jacob
