Hi all

I am thinking about fitting a eberspacher diesel heater into our Westerly Centaur but not sure where to actually install the heater if we do.
I know we will need to feed the exhaust to the stern but looking for ideas on where to fit.
We have a B Layout Centaur and so have any other Centaur owners out there fitted one and if so where about did you fit it please?

Thanks

Kev

Hi Kev, I can't answer your question directly but suggest you might get advice on the Westerly Owner's website. Plenty active posters there and probably some will have done just what you are proposing.
All the best,

From what has been said on here in the past, the Planar-branded version is well regarded. Look at the relevant threads before deciding with a view to saving money over the cost of an Eber
Care is needed when buying Planar heaters. The name is not registered and thus can and is used by Chinese advertisers. Planar changed their name to Autoterm to overcome this confusion.

Fit it as far to stern as you can. I know it means longer hot air ducts, but you want the exhaust outlet as far astern as possible or the exhaust fumes will be a nuisance, and you dont want any longer run than necessary of hot exhaust pipe or you have a less manageable fire hazard.

So sadly one of your cockpit lockers is the logical best compromise unless you can somehow fit it in the engine ebay

I know you really want Centaur specific advice but have you studied the Eberspacher marine installation guide? On a different boat, I followed this guide when I fitted mine and it has been trouble free for 10 years so far.

As I posted I am facing same question ... where to install.
It may seem obvious but :

Location needs to be so the exhaust is short and complies with the installation manual.
If in a locker - the unit and its pipework - especially exhaust needs to be partitioned to protect the other use of locker and the unit itself.
Location needs to have good access to install hot air piping for cabin
Easy access to fuel tank or sensible piping from main tank with stop valve
Reasonable location to site control panel (and thermostat if fitted).

Obviously every boat is different, but on our OC320 it is located in the cockpit locker against the bulkhead to the heads. The exhaust has no silencer and goes straight out thru the hull side, maybe 18” long. Despite not having a silencer, it is not particularly loud especially once warmed up. The hot air pipe feeds thru the bulkhead thru the sink cabinetry and into the cabin. Protecting locker contents from coming into contact with anything hot isn’t too difficult. Now of course, the lockers on a centaur are likely to be a bit smaller than ours but it might give you some ideas.

My recollection is cockpit lockers on a centaur are limited to one stern one behind tiller . If you don’t put there then I suspect under the wooden grating and grp floor hatch as far back as possible for a short exhaust pipe run to exit port on stern. As said WOA might help or you might send a private message to Concerto being a fund of Westerly info.he has posted on utube as well .

Just a comment re. Eberspacher, Chinaspacher & Autoterm/Planar. I’ve had all three. Ebers are fine but not worth the expense in my view. China good for a replacement for a clapped out Eber because you can use all the old fittings - those that come with the Chinas are not suitable for marine use, so you have significant additional expense. I fitted a Planar/Autoterm to my current boat, but as Vyv points out, beware eBay sellers branding Chinas as ‘Planar’. The Autoterms are more expensive but well built with marine quality fittings and they work well. The smallest version would suit a Centaur and keep you toasty wam.

One thing that was pointed out to me in discussion with a yard fitter .... exhaust outlet best placed centre high up transom ... so that when sailboat heels - the outlet is not under water ... which can happen if put to side or near outer edge.

I looked at on with the heater mounted in the toilet compartment with the exhaust existing from the cabin roof.
The engine compartment is very large on the centaur with easy access to mount the heater and run the ducting. The exhaust could then easily exit via the transom. This seems the easiest and least work.

My LPG system has deck exhaust outlet ahead of mast on stbd side. When not used - its not used by me - it has a 'top hat' to stop water entering.

Checking the Diesel heater installation manual - it says not to do similar .... basically exhaust to be horizontal.

When I got mine fitted on a Renown, the fitter put it in the engine compartment and led the exhaust by the shortest distance to an outlet on the port side at the level of the go-faster strip near the rubbing strip. Not the ideal position on a Renown as that puts it alongside the middle of the central cockpit. I assume that leading the pipe through the after cabin would have been too much hassle.
