Eberspacher questions

[stefan_r]

Have just got a D2 installed and got some questions:

-1- I have an exhaust silencer but still find it a bit noisy...any ideas? It's not the air noise whooshing about but more the mechanicals

-2- I have been told you can get an intake air silencer...are these any good? It is primarily the intake air that is noisy and I think the noise from that is echoing down the tubes. The unit is installed in the engine bay and is about 6 metres from the cabin.

-3- What suggestions for servicing and spares to carry on board?

Cheers!!

Ebers are a bit of a hobby/ beer money thing for me these days.
I test them in my workshop/shed I always have an exhaust silencer to pop on and they do make a big difference as you would expect. I was very suprised, though at the reduction of noise when I pop on an intake silencer. They are well recommended and can be bought on EBay (not me !!) for around £15.
Spares are expensive, dont bother but make sure your fuel is clean, power supply good etc.
If you really need your heater then the best spare could be a second hand unit from ebay ( c£150), test it so you are sure it works then wrap it in cotton wool as a spare!!
You can then be assured that your unit will never fail you!!.... Oh..but the pump is then sure to fail!!

You can silence the intakes by plumbing the air from a locker or by creating a baffled structure with plywood and noise insulation material

You can get combustion air inlet silencers, exhaust silencers and heated air inlet and outlet silencers, they all help reduce noise. I recently moved my heated air inlet from a cockpit locker to the aft of the cockpit ( so it now faces the companionway), to draw in fresh air and it is now much noisier, so I am going to fit a silencer to the heated air intake.

To prevent the need for much servicing:

1. Use road diesel, not red marine diesel; it's a better grade. It's not an old wives tale, they are different stuff and the burner in a diesel heater is less tolerant of it than a diesel engine is.

2. Use it on a high setting for a least an hour at least once a month, even high summer -the problem is that in mild weather it's tempting to just use it on a low setting at night and over time this contributes to the burner coking up.

Re servicing.
Heres a link to the technical manual, not much to them really.

What's every ones view on where to draw thw air to be heated?

I have been recycling air for my D1LC which I am currently refitting as I was never happy with my initial installation. (it ended up rather untidy)

The unit always cut out a bit too often... and I am tempted to draw in fresh air.


If I go for fresh air I'll need some sort of fitting to draw air from the cockpit in to the aft locker... any suggestions.

The heater, if it's like my DL1Cc senses the intake air temperature or has a remote temp sensor. If you don't have the remote temp sensor and draw external cold air the the heater will always run at full speed. If you draw air from the heated area then as the temp rises to the set level then the motor backs off and reduces its output. If you draw air from an external source you really need to have a remote temp sensor fitted.

Does anyone know if I can upgrade from a D3L to a D4 and retain the original control unit, pump, etc? It would be nice to get the extra heat, from eBay purchase, without having to buy the extras. Any ideas?
