Thanks Finny,

The heaters that I am referring to are mostly ex BT vans or ambulances and all 12 volt.
Mine looked almost brand new EXTERNALLY and does not smoke at all at any time.
If it lasts 2 winters I'll be happy.

The 24 volt versions sell much slower on ebay and do not achieve the same price as 12 volt units.

All I previously knew on fuel is that Bio-diesel is not recommended. I know nothing on this subject but seem to remember something about it being less pure and clogging the unit up??

Anyway, I must get off this addictive forum and finally do some work.

Hi finny,
Yes thanks for that.
All I can say is that our unit seems to be working fine with no ill effects evident.
During the recent very cold snap it was kept on all day and only shut down when we went to bed.
I won't leave it on when we are asleep however, even after I have replaced the rubber fuel joints mentioned earlier.
I know various auto shutdown safeguards are built into the design of these heaters (and very efficient they are too) but relying on them whilst I am unconscious in my bunk requires a leap of faith that I am not prepared to make.

Having it start up automatically about 15 minutes before I fall out of my bunk in the morning is sheer luxury though.

That looks very much like a JGM Madeira 27, which is the boat I own (mine is on the River Great Ouse).

I have been thinking of getting an Eberspacher for mine to replace the gas heaters. At the boat show I was quoted £1000 for the unit and £450 for fitting. I don't mind buying the unit new, but the fitting seems a little steep!

How did you connect the fuel line to the tank?
How have you routed the warm air pipes to both cabins?
Could you have also put an outlet into the cockpit?

I also have lots of questions about the Madeira.

Hi Cattleya,
I answered your PM about Madeira's before seeing your post here.

The fuel is taken from the main diesel tank using an Eberspacher metal stand pipe (you can buy these on Ebay).
I have cut the length to prevent the heater from using any more fuel when the tank is down to one quarter full.
At present I have no fuel filter in the line. This is something that I am considering but all I have seen so far is PLASTIC cased filters for the 2mm i/d tubing (I'm sure that would be another BSS failure point, if fitted). I will post a picture of the tank take-off after I next visit the boat.

CABIN OUTLETS:-
I have fitted 3 (forward saloon / cockpit / aft cabin).
This really is the absolute maximum number if you are going to have them all open at the same time.
In the recent very cold snap, I just had the cockpit one open and it was bliss (No more need for hot water bottle laying on feet to prevent toe freeze up while at helm, and outlet is on opposite side to helm!)
In warmer conditions we need 1 outlet fully open and a second at least slightly open to prevent overheat shut down after about 1 hrs operation - the ducting used over the years has slowly been reduced in size (remember the old Webasto's that used massive ducting).
I think that it has now reached it's smallest size to allow enough air through the heater. Maybe siting the heater in the engine compartment is also a factor here, but it is a minor consideration to remember cracking open a 2nd outlet slightly.

continued in next post..

For Madeira owners:-

Outlet in cockpit is under seat on port side and very easy to feed ducting to.

Outlet in aft cabin is shown in previous pic.
Ducting runs under port bunk inboard at top (I will be boxing this in under the bunk and surrounding the duct in glassfibre insulation - inside the boxed section). This takes up a small amount of storage space but at the very top and out of sight. Again ducting easy to run through engine compartment bulkhead under the heater, high enough to clear the exhaust pipe (again see previous pic.)

In Forward Saloon it would be easy to lay ducting behind units on port side and fit outlet under port side seating. Eberspacher advise to prevent air outlet from being very close to legs - can be quite hot.
We opted to have under stairs. This is fine in the cabin, but I am still not happy with partial obstruction to starter battery access. Clipping duct round to this location also tricky - ours only temporary supported at present.

Eberspacher suppy insulating jackets that you can put over your ducting.
I believe they call it "Maxi-Therm."

It comes in lengths of approx. 0.75 metres and in 2 types:-

One is a flat sheet with clips along the edge that you simply wrap around the duct and clip together.

The other is is tube form and slides onto the ducting.

cost about £9 something per length

On all such instalations one vent should be incapable of being closed (often the one in the Saloon) that way you cannot overheat the system

If we were ever to sell the boat, I would fit the spare non closable vent that we have on board, in the main saloon.
As it is, we prefer the flexibility that the current set up provides - it allows for a strong blast in the cockpit during very severe winter conditions.
Don't know whether we may be forced to do this permanently (under BSS requirements).

If anyone does buy one of these 2nd hand heaters, send me a PM with the model number on the casing (25 #### ## ## ##) and I can give some useful info.

One thing to note is that the ex BT van units come with a separate 1 hour timer which can be discarded BUT.....

CERTAIN VERSIONS of the "D1LC compact" require an external relay in circuit (to take the current supplied to the glow plug on start up and fuel pump during operation).
Without it, the current would be routed through the contacts on the control device (standard rheostat or 7 day timer etc.)and cause damage.
The 1 hour timer includes this relay.
Later versions do not route the heavy current via the user's control device and therefore do not need to retain a relay in circuit if you remove the timer.

My heater DOES NOT need the external relay and is Cat. No. :-
