Will diesel heater skin fitting be below water line when heeling?

3m. seems a very long cockpit for a relatively small yacht? Even on yachts much longer than yours the established practice is to install the heater aft with an exhaust discharging through the transom. It is neither difficult or expensive to add additional insulation to a duct though the losses through aluminium ducting are not that great and can have benefits.
If what you are planning was considered better do you not think that lots of folk would already be doing it? The problem with gas poisoning is that you can be dead before you are aware of it, it is not somewhere to cut corners.

I wouldn't mind moving heater it's simple enough
Its just it's then a 3m run to cabin and air much colder by the time it gets there.

If you insulate the ducting, there'll be minimal loss of temperature. The installation on my boat has around 6 metres of ducting between the heater and the main cabin vent, and the air is still very hot!
 
3 metres is the length the duct run would be if i was to mount heater at transom
I guess I could try heater at transom and test it and make sure it heats the boat okay before drilling the exhaust
I'm not saying it's better. Just an option. It would seem people already are doing it this way.
I'm not sure what the risk is of gas poisoning is with heater going out the side of the boat to be honest.

Cheers Pvb I'll give it a shot with the longer duct and insulate it and see how it goes
Is yours a 2 or 5kw out of interest ?
 
I has similiar questions when i installed my 5kw chinaspacher. I decided to go for fitting the heater in the lazarette, leaving a 3m+ run for the ducting. I have 3 outlets and insulated the ducting. I've not had artic conditions by any means but the boat heats up really well and slows to a low setting quite quickly. I think its only using its 5kw (actually about 4 European kw I reckon) for a short time. Your 2kw should be good but may run on maximum noisy level for longer.
Are you sure you have a 2kw? There seems to be alot of re-badged 5kw heaters around if facebook moaners are to be believed (They complain as 2kw is smaller and plenty for most motor caravans)

Fitted in my 31' Westerly, apparently best thing I ever added to the boat says the admiral
 
Hi tzu yes mine is the 2kw - I went for a planar not one of the Chinese ones but it seems like they are much the same (except the price!)
Yeah they are great aren't they. We were at Crinan for a week Just recently and we wouldn't have stayed the whole time if it wasn't for the heater. At the moment mine is fitted at the forward part of the cockpit locker so the duct into the cabin is short and it heats the boat really well. When I tried it with a longer bit of ducting I thought there was a lot of heat loss which would mean I'd probably need to have the heater on full blast if I moved it to near the transom so it wouldnt be as efficient. But then again I had not insulated the duct. At the moment I just use it with the exhaust into the cockpit locker secured on a couple of pipeclips so it's only temporary - but knowing me it might stay like that for a while ! Only thing is I need to have the cockpit locker open to use it !
Cheers
 
Hi Crinan 12 Interested in fitting a diesel heater in my Centaur and wondered how you got on with the Planar over the last few years.

I was going for a 2kw but reading some of the replies you had it seems a 5 kw may be a better option.
 
2kw plenty for my boat, makes it nice and warm even when it's pretty cold outside. Rarely have it on max either - well just to begin with then tend to turn it down and it's still plenty
Cheers
 
Thanks for that. A few times early last year we spent nights in marinas purely because of the cold.Not as tough as we were 40 years ago!
 
We keep the boat in Cardiff Usually spend the summer down in Pembrokeshire .Have gone across to Southern Ireland in the past and look forward to going again .

Are you in Scotland I guess from the name?
