Installing a Webasto diesel heater on SO 36i

[allegria]

Hello all,

I am looking into installing a Webasto diesel heater in my 2010 SO 36i.
I believe there was a factory option for this.

Has anyone on the forum got a factory fitted one? If yes, could you provide pics and location of:
1) Heater unit
2) Exhaust
3) Vents

If anyone has a dealer fitted option, the same questions apply.

I am aware of the Hints and Tips from Trevor in his 42DS that you can find here

Cheers,
Allegria

Hi 
I cannot give you advise on installing a Webasto heater as my SO 32 was factory installed and a different model. What I would recommend if at all possible is to route the heating pipes and vent to the toilet/shower. I wish mine was. There is nothing worse than getting up in the morning to a nice warm cabin and going to the toilet in a fridge. Just a thought!

Hi, mine is factory installer on a 2011 36i. The heater is installer in the space behind the rear cabin on starboard side, with exhaust directly out on the same side.

Vents and pipes installed:

- Rear cabins on the rearmost divider
- Shower/head below the sink blowing towards the head
- Saloon, below the seat in the compartmen for the hot water unit, blowing towards the chart table
- Cabin in the front of the boat, low down on starboard side blowing in parallell with cabin door.

The control panel for the heater is located just above the 220V plug starboard side in the galley.

Some bad english phrases here, but can add pictures next time I'm in the boat (this week).

Regards,
Dag Ragnar

Hi Allegria,

I found it to be quite a substantial project actually, with a lot of facets requiring consideration. I was lucky to get the original diagram from the factory. Either it was obtained from the factory or someone on this forum had it (I cannot remember now) but it was very helpful in outlining what was included in the factory installation. It was simply a plan view of the hull with the location of where the ducts ran. Perhaps you could approach the factory for the same diagram. Sometimes they are very accommodating.

I am sure on the SO36i the 90mm ducting is already installed behind the galley as that seems to be standard practice for Jeanneau.  I also used to look for photos online of my model boat hoping to find shots that revealed the exact location of the outlets so I could make mine the same.

Great project and it works really well. The Admiral feels the cold very badly and it has made quite a difference to her boating life (and consequently that has made a difference to mine ).

Regards,

Trevor

Thank you all for your replies.


Ken, I agree, a vent in the head would make sense.

Dag, This is very helpful. I assume you have a 3 cabins from your response. Mine is a 2 cabins, which makes access a bit easier and I suspect the heater unit would go into the lazarette.
If you could send/post the pics, that would be great.
In particular, I would like to see the exhaust from the outside to check the position and height from the water line.

Trevor, I agree with all your comments. I have seen the diagram for the 42DS and I will try to contact the factory for the 36i.

Thanks again,
Cheers,
Allegria

I have a SO 36i with a system installed as part of commission in 2012. 3 cabin version.

It is much the same as described by dagern with the exception of the control panel. Mine is located under the main DC control panel (port side). From memory the cutouts for all the pipe work were in place from the factory.

The location of the heater is starboard in the space aft of the cabin at about the level of the aft cabin shelf. The main duct from the unit runs forwards under the aft cabin shelf, with a spur running in the aft space to go to the port aft cabin and heads.

Hi,
I had a wabasto fitted by dealer from new on a SO33i. Its mounted right aft just to port of the centre line on a stainless L bracket bolted to a frame running fore and aft under the bathing platform the hot air to the cabins runs down the port side with a T off to the aft bulkhead of the aft cabin then through the lower locker of the heads and into the saloon under the port seats with a T off for the saloon with it terminating in the ford cabin at the bottom of the port cupboard.
The exhaust comes out on the stern port side about 3ft up from the bottom of the bathing platform. 
The only things for my need I would have done different if doing again. Is having the exhaust coming out on the side as it gets pretty warm and if you store a dinghy on its side on the bathing platform you have to be inventive to keep it clear of the exhaust. Also I wish I had a timer control fitted as would make a good heater even better. Also managed to strike a deal when buying it to get them to throw in insulation for the ducting which worth having.

I installed an Eberspacher D4 Plus when I bought my 2010'36i a couple of years ago. I'm very happy I did install it, very helpful also,to,reduce humidity. 

Heater unit is in the comoartment aft of the starboard cabin, close to the fuel tank. 5 vents: one fixed in the dinette, the other ones can be closed: 1 per cabin and one in the heads. If we only use the bow cabin, I close the vents in the cabins (as well as the doors) and heating the boat is even faster. Control unit is on the starboard side, on the small vertical panel left of the kitchen's cabinet - just left of the refrigerator. 

Only small complaint with Eberspacher choice is that its control dispoay  is probably a bit less intuitive than Webasto, even if you can programm up to 3 scheduled start once you get used to the interface.


As I said, very happy with it feel free to ask more details if needed!

I was forgetting THE real problem I'm still suffering. In order to install heater you need an additional fuel inlet (outlet?) from the tank. They installed one in the central hole that was available. But it appears impossible to properly seal it and its screws. Every time the tank i superfull... It leaks oil... Very bad! I'm still struggling with fixing it after two years... ((

In the SO42DS kit the outlets are all able to be closed apart from the large 90mm (or 80mm?) outlet in the saloon. My understanding is it is important not to create too much back pressure for the Webasto unit and a way of not accidentally being able to do that is to have the saloon outlet constantly open.

Hi Trevor,

Thanks for that comment. I am planning to stretch the Air Top 2000 ST with 4 vents.
1 always open in the saloon, 1 in the heads closable and 1 in each cabins (2), closable also.

Dear all,

Back on this project... And after lots of reading, looking now at a Belief diesel heater 2.2KW.
A lot cheaper than the big brand name... And yes, I know where it is made...
Has anyone had any experience with the same?

Also looking at installing only one vent in the saloon to start with...

Cheers,
Allegria

Hello Allegria,

Where are you standing on the heater install? I am also thinking of fitting my 349 with a Webasto but I am afraid the retrofit complexity is going to make the installation a lot more expensive than the factory install. I like Webasto's Top Air 2000STC but this being the smallest model, I am afraid it may be a bit undersized for my boat. From Webasto's selection tool, looks like a EVO 40 or 50 model would be more appropriate but those are also much more expensive than the 2000STC.

Best,
