I have it on good authority that you can only leave radiatior central heating ON (all night) on a boat, stupid question but I know how warm air heating works but how does central heating work, and more importantley, keep working on a boat, boiler?

Is it safe, what about ventilation for the "boiler"? and the other thing that bothers me, what about the space and weight that this lot takes up, or can you use flexi pipe and compression joints?

I've got warm air heating, but the water heaters I have seen are basically the same as the warm air heaters, but with different heat exchanger arrangements. I can't see any reason why you should have to leave a water heated system ON all night (unless you're in danger of -20deg C temperatures). But then, I may be missing something. I know that Webasto have good brochures which should explain that. Look them up on google. Also Mikuni? Artic? Not sure if Eberspacher make a water version.

Yes, you can use flexible pipes and compression couiplings. I did. Do a search on KABOLA and you will find a number of posts on heating. Mind you: Webasto, Ebersprächer or Mikuni are not for permanent use. I think they are fine for occasional heating, but certainly not for more serious work.

They all do hot air and hot water systems. What you choose depends on many things, boat size in the first place. If you choose your radiators carefully they need not be bulky or heavy at all.

send a PM if you need specific info.

Consider a Dickinson

Paul

See my post on "Paraffin heaters" further down the page. We have a Dickinson diesel heater with a chimney and a pipe to waft air around elsewhere. It's cheap to run, virtually silent and has a wonderful cheery glow through its glass door. We wouldn't have found room for radiators - never regretted this purchase - wander into the saloon/galley for coffee without getting dressed in December - brilliant !

You might be interested that I am fitting to the 60ft schooner I am building -a combi boiler and radiators -just like home!!The diferences being that it will be a 24 volt, diesel fired (from the main tank) unit with it's own dedicated batteries (of course,re-charged automaticallly from the genny). A pressurepump/tank unit will maintain the pressure. The radiators will be finned pipes running around the perimeters of the cabins,etc where practible,tucked into receding plinth areas -just like your kitchen units!)should be nice and cosy.Small fan units (individually controlled) will be placed behind the finned pipes to aid distribution of the warm air.The a/c air will be piped through these.
