    Posted: 02 January 2020 at 08:55
Hello everyone and a Happy New Year.

I am a 385 2014 owner.

I am thinking of installing a Vebasto Heating system. Although I have lots of extras when I ordered my yacht never thought that a heating system would be useful.

So I have a couple of questions to anyone who might know a couple of things.

A) Is there any other brand apart of Vebasto? Model details in order to search price etc online?

B) Is it possible to install a heating system after purchase? I have heard that it is but more opinions are always helpful

C) How much roughly could it cost in case someone installed it after yacht't purchase?

Thank you very much again for your time and interest!

Haha.  I didn't specify heating either.  I planned a year in the Baltic before heading south.  5 years later and I'm planning to visit Scotland next summer!
There are several other premium brands, notably Eberspacher, however I have heard good things about Planar with I think might be Polish.  Lots of Chinese alternatives on eBay too.
I fitted an Eberspacher myself in my last boat.  Filling the heater itself wasn't too difficult but harder to run the ducts.
I think it should be easy enough to get something through from the starboard locker (where I imagine that the heater will be fitted) via the galley cupboards and into the settee base.
Let me know how you get on.

Thank you so much for your instant reply.

You are pretty straightforward regarding brands.

Two more questions based on what you wrote me back

A) What do you mean by saying "running the ducts"?

B) Place it on "the starboard locker via the galley cupboards and into the settee base" meaning it will be installed where? 

Thank you very much once again!

The system comprises the heater itself which needs to be fitted near the stern to allow fitting the exhaust skin fitting which would usually go on the transom.  There also needs to be a fuel line to the diesel tank.  The heater has its own fuel.pump.
The heater also requires an air feed (input) and of course the hot air outlet.  These are usually quite large pipes (ducts), maybe as big as 90mm.
I have the single aft cabin version so the starboard locker would be a good location for the heater.  If you have the double aft cabin layout you might need to put it in the void behind the cabin, but it is a pretty confined space to work in.
The hot air pipes (ducts) are the only difficult item to fit.  I would suggest looking at a way of getting these from the starboard locker/cabin into the galley cupboards just above the floor.  There maybe a passageway behind the fridge but I think you would need to make a hole in the panel between the fridge and the settee base to see if this is suitable.
Once into the settee area, it should be easy to get forward into the main cabin too

I can comment on the 418 (which let's face it is very similar) and an installation I did on my previous boat.
To be honest it's pretty easy to retro fit. I've just lagged all my ducting on the 418, which was arguably harder than it would have been to retro fit the actual duct!
 
My heater is in the aftmost cockpit locker with exhaust going out the port qtr. The supply and control cables run from that lkr under the port aftcabin bunk, behind the locker in that cabin, behind the heads lockers and up to the main electrical panel, with the heater controller at the chart table.
 
The ducting runs under the bunk in the stbd aftcabin, where it veers to port for the port aftcabin (via the engine bay, behind the saildrive) and then on to the heads. The main run continues from the stbd aftcabin, behind the locker, the behind the galley, alongside the water tank under the stbd saloon berth where it exits into the saloon and also branches off to the forecabin. You probably appreciate the ducting size steps down as you get to the outlets furthest away from the heater (eg the forecabin, heads and two aft cabins. Well worth adding the insulation to the ducting as you go (in my opinion).
 
If you have the locker under the oven then you may find a trim panel at the back of that locker that is easily removed (couple of screws). This makes routing the duct from the aftcabin and behind the galley pretty simple. You will need a decent set of hole saws if Hanse didn't pre-cut the duct holes. If you don't insulate the duct, then I would at least insulate the part under the galley as this is where the fridge compressor is. Good luck

I did a heater retrofit on my last Jeanneau. On my current Hanse I ordered iright away:  Here are my 2cts:
1) You can buy either a Webasto system or Eberspächer. Both are fitted by reputable truck and van manufacturers as a standard. You are able to get spares virtually all over Europe. Planar is made in Russia and it is dirt cheap. There is a new German manufacturer Aeroheat as well.
2) When selecting the heater location, you have to  consider:
- routing a fresh air duct to the heater unit
- routing an exhaust pipe from the heater unit, this MUST be well insulated by heat resistant glass or a stainless cover as it gets VERY hot. make sure that no other "cargo" in the compartment can touch it.
- routing initially a 90 mm airduct from the heater
- routing an ample sized 12 Volt supply from the battery to the heater ( take rather 6mm2 than 4 mm2) as this is critical for the start up process
-routing the mutli wire cable to the in cabin control unit ( select one which aslo displays any elctronic fault codes
- routing a suction pipe from the diesel tank, which does not reach to the bottom of the tank
- routing a cable to the heater diesel pump, mounted close to the tank outlet
 Depending on your boat this needs a careful planning before starting 

3) Routing the heater ducts. This is a clear PITA job. For a 385 route a 90 mm duct directlly to a non closeable outlet in the main cabin under the companionway. Presumably you pass this through the engine compartment. This pipe needs a aluminium covered glass wool insulation.

4) For the other cabins you can reduce the air ducts to 75 mm dia. Buy a good hole saw tool before and check wether this fits attached fits.  Thewre should be ducts to the aft cabin(s), toilet and to the forecabin. All the vents should be closeable. Take off any panels possible and check the space available for the ducts and your hole saw. For the front cabin it is advisable to mount a small computer fan with a switch just in front of the outlet. 
All pipes should have a thermal insulation fitted before installatio.

Besides raising the comfort level during bad weather teh heater also delivers dry air to dry your wet foul weather gear!

Good luck

If you look at these pictures of the unassembled Hanse 370, you may get an idea of where to place the heater.

I spent some time recently researching the available diesel heaters. You may find it worth looking up the Chinese Diesel Heater group on Facebook to gain some insight into the cheap end of the market. Not trying to convince anyone, however the price v value v quality is worth evaluating for yourself. 

Also, if you are in a hurry for a solution this winter then install the heater and leave the ducting until later. You can run a temporary main duct hose into the cabin quite effectively. Try a silicon hose rather than the plastic concertina type.

Hi Knick,

in end of 2015 if have had the opportunity to visit the shipyard of Hanse . Because I am an owner of H385  #407   I took some photo shots of a 385-type under construction. In some shots you can see how  the hoses for the heated air are placed and located. Especially you can see the openings where the hoses are put through.

If you like you can send me your email address to: edelphant@gmx.de and I will send you a link for download the shots.

yours, MAGNUM
