Not being specialised in this field, I can't give you a technical answer. However>>> If you look at the rated output of a Diesel Bubble stove with back boiler (My Bubble back boiler is 3.5KW output, the fire around 5.5KW I think), and runs 2 rads and the calorifier coil),I have a small wtare element to make and fit to warm up my toilet and I have a Eperspacher fan heater to fit in the rear cabin. I think the fire is able to handle all this for me in due course. Alternatively, look at a Morso "Squirrel" stove with back boiler, then read off the manufacturer's rated output, you will get some idea from this info. I know boaters with 58' 0" and 62' 0" boats with these items fitted and their boats are too warm, on a low setting in the coldest of weathers. The boats are Spray Foam Insulated.
You should be able to draw a pretty good conlusion from the above. Regards, ~Allan~ --- In [email protected], "rb999sb" <s...@...> wrote: > > Will 10,000btu boiler heat two double radiators plus a calorifier. How > do I work out what size we need? > Sue >
