Hi Dazclare, I would be interested to know more about the Eco fan... We too, would like to find a way of getting some of the heat from our fire to the other end of the boat, without running the batteries down in the process.

been told computer fans spread about boat will suck and spread the hot air around sounds a cheaper way to go but still using battery power where ecofan don't!!!!!!but think it's what we are going to do is get computer fans for now it's trial and error all the way haha

I had a look at the Ecofans... They seem very expensive for something that doesn't do a lot. ( other peoples comments on them were not very favourable either, although one chap thought it was great to watch it go round.. ;D ) I think the computer fans sound interesting and they use very little battery power too. I will carry on looking for other alternatives ... Any one else out there got any Ideas...

We had thought of buying an ECOFAN but in the meantime tried ducting heat from the back of our wood burner with a lot of 4inch ally tumble drier ducting with a 12v brushless fan (ex steam age computer) in line below the cabin floor.........It didn't work as there was to much heat loss on route and needed INSULATED ducting. That may have worked. Still learning. N.B. computer fan i used draws only 0.08A. not that thirsty!

Hi , Pity it didn't work Shedman, heat loss through the ducting is a problem. I did give that idea some thought myself but at the time I had nothing to use for the ducting. My boat is 44ft.long, a long way for the heat to travel to get down the back. I gave up trying to find a way in the end and have now fitted another multi-fuel fire in the back cabin. It's great, better than central heating, the whole boat is now as warm as toast.

i fitted a back boiler to my wood burner and have 3 radiators running through the boat.
ive been using it for over 9 years now without problems.
it runs on a self circulating system as i dident want to have to rely on a fan.
ill try and do a drawing of how it runs soon, if it would be of any help.

I originally fitted a stove with a back boiler with the intention of fitting radiators, But I couldn't find a pump with a low enough draw on the battery, keeping in mind that it would have to run 24/7 . I have heard of running radiators on a self circulating system but I could not find any information on the subject and I looked everywhere. As I was not sure of the details of how to do it, I gave the idea up and changed the fire for one without a back boiler instead. SO! Jill, although it's a bit late now for me, I for one would love to see a diagram of how it works. I'm sure it would be very useful for others thinking of fitting one.

Hi Roy this may be a bit late in the day but have a chat with Manko for a pump that i Think uses about 0.1A by kubola (spelling prob wrong) and similar that are available. We spent some time looking into this for those lucky ones with back boilers. This level of current drain IMHO is acceptable for comfort and replacable with solar even during the winterwith the right panels and controllers. Having said that Jill's system works rearly well from what I can remember and relies on the wonders of gravity and heat rising......Lucky girl.

Thanks for the info. Colin I couldn't find a pump as low as 0.1 A at that time, something like that would of done for what I wanted. Never mind.
