Eberspascher and fitting

[Guest]

Interested in ideas from anyone who's fitted or has a small single outlet Eber fitted to their Centaur, Sunrider, Colvic similar boat of 25 - 26 ft.
Where do you have the heater unit fitted, air intake and where do you have warm outlet.
There are 2 of us looking this question to fit systems to our boats and we have pondered all sorts of ideas etc. - but haven't solved the intake / outlet locations and how .....

Getting soft nigel?
You could probably mount one in your engine compartment with the intake from a locker. The exhaust is another hole in the boat on stern area on yours. A short pipe and 3" hole under the steps will heat the boat nicely.

Hang-on ..... I asked those with small boats !!!

HR 42's have a lot space to fit lifes luxurys ..... my modest offering is already cramped !!!!

Actually the question is based on Jim's Centaur ..... and my wish to sail to baltic. He's just got hold of one and works a treat - just now trying to figure out the fitting of it. Once he's gone through the trials etc. - then I may go with it also !!

Re: Hang-on ..... I asked those with small boats !!!

Sorry mate - only trying to help - I had a small boat too for a long time. A lot smaller than (both) yours. In fact a wooden caprice was my pride and joy for a long time.

Only joking mate .... I\'m back mid april .....

Ian .... I was joking - honest no problem !!!!!

Jim and I are hoping that a similar boat to ours will have fitted one and then we can crib of it ....

BTW - once I figure out where to put the diode on the alternator - I will reconnect the split diode thingy ..... cheers !!

You could just replace the battery switch with it.

I have a dual outlet on my canoe sterned 26ft Victoria. Its in the starboard cockpit locker high up on the hull side. The exhaust is at the rear but the inlet is inside the locker, which a surveyor has mentioned could be a problem but it would be a simple matter to put an extension tube on it and lead it into the cockpit or somewhere else. One outlet is in the main cabin and the 2nd is in the forecabin. The control is below the bridgedeck just inside the hatch. Hope this helps.

Diode splitter ....

Problem is alternator is machine sensed and it failed to charge sufficiently. So I have to cheat the alternator by causing a small voltage drop across the back of it before it goes out to charge system. That way - I don't need to change alternator etc. I'm told that the diode to fit across alternator terminals is only a simple low power job ..... so will try when I get back - obviously in consultation with matey at the repair shop you directed me to !!!

Cheers

Hi,

Can you clarify a couple of things for me.

Firstly. Did your surveyor clarify why having the combustion air intake from within the locker could be a problem. I plan to do this myself.

Secondly. Where are you drawing in the air to be warmed. (sorry if I've missed the point)

Now you've got me thinking!!! I have dug out the survey and quote' the main criticism is that the heater's flue was on the hull side, just opposite the locker lid which formed the only vent for not only the combustion but also the heating air. It would be possible for fumes to recirculate into the cockpit locker and thence into the accommodation, with potentially lethal results'. Recommendation: relocate the flue, or trunk the fresh air from a point where it cannot possibly be contaminated. Hope this helps.. This was for the first Vic 800 I looked at that had a generally lousy survey. I didn't buy it but found a better one, and the installation was identical, as fitted when the boat was first built. The boat I now own was a boat show model and was DTI coded as a charter vessel (!) a tax dodge methinks...
It's possible to have the warming air trunked in form the cockpit direct I was told but I have'nt bothered. My problem is that with a 75 AH battery the Eber will only run when the engines running...Ok to warm up the boat but not to leave it on all night..

You can get a manual from www.espar.com which does give some good instalation tips.
Just as your engine needs a good suply of fresh air, so does the eberspacher. Ebers. have very sensitive safety cut-outs and if you do not install properly then you will get the problems which you read about on the forum.
My intake (which has to be balanced..the same length as the exhaust) is in a cockpit locker with the end just next to an airgrill.

My eber. is in the engine compartment and the hot air comes through a 2 foot long duct straight into the cabin. I would not try to install any more sophisticated ducting as it involves cutting loads of large holes. The hot air circulates throughout my 30 ft boat no problem. The air to be heated comes from a cokpit locker that has a space in the bulkhead through to the cabin so in effect the air comes out of the cabin and is recirculated. If I want to let more fresh air in I lift the locker lid and trap a fender rope in it to leave sufficient gap for air flow.
My Eber. has only ever started at the second attempt but has given excellent service over 2 years (it was ex-GPO van) and I do run it throughout the night on low heat perhaps a couple of times a year. I have 2 110amp domestic and a seperate starter battery and even though I am on a swinging mooring battery useage (contrary to some opinions) is not an issue.

I fitted my own airtronic heater to my 26ft Albin Cirrus 3 years ago. I fitted the burner in the cockpit locker with fresh air intake in cubby hole space in cockpit. The hot air out let is at the base of companionway steps pointing forwards. It is the best thing I fitted to my boat and a joy to sail the cold Summers of the West coast of scotland with.

Hot toe's to you all

Hi
My boat is a CW 26 I fitted an ebersplasher last year. the boat has an open wheel house I fitted the heater unit in the port wheelhouse locker. The exhaust goes out thru the port side (I take care to position fenders accordingly) the hot air outlet emerges at ankle level under the saloon settee (on port side). The second hand unit I bought had a smaller additional outlet which I have ducted up to the windscreen on the port side. The heater air intake is from within the saloon the burner air intake is from wihin the locker which is vented into the open wheel house. Hope this helps.

Mine is mounted in the port cockpit locker. Exhaust has a short run out the post side with a swanneck.
The locker has a large open vent. The heating air and combustion air is taken directly from the the locker.
The control is on the port bulkhead just inside the companion way.
1m of hot air ducting, coming out at ankle hieght under the rear dinette bench, with an adjustable vent.
All wiring is very short about 1m .
Works a treat. Soon drys the dog and oilies....
The only time it stopped working was on low volts. 3 days of wet cold weather not moving. (Aug last year)
