<span style="color:red">Dear Sir,
I am a happy customer of Eberspächer hot air Diesel heaters as are many in the UK leisure boating industry. Boat heating has now almost become the first on the list of upgrades made to yachts and power boats in the UK allowing us to extend our sailing season through the bleak winter months.
Herein lies a few problems, the heaters are left turned off for up to seven months during the summer months, although this is a massive over estimate judging by the summer season we have just left.
Although thus far I have either been lucky and come September / October my 1DLC has powered up and warmed the boat up with no problems. I am a regular contributor to a leisure boat forum and occasionally Usenet group. You may be surprised how often certain questions arise concerning Eberspächer heaters and how little is known by the thousands of users. Information regarding these heaters is often gleaned from the few dealers in the UK, who when busy do not have the time to stand and answer a multitude of queries. I hope you can answer a few common questions for me that I may take to the forum I use, or pass this email to the relevant department who may be able to help me. </span>
<span style="color:blue">1. The 1DLC is very popular on smaller boats as it can be obtained regularly 2nd hand from the truck / van industry. With regards the 1DLC and the usual marine Eberspächer heaters that you provide, would you explain the 10 strikes and you are out safety feature, i.e. After an unknown number of false starts the unit locks and must be reset by a dealer.
a. How many false starts is it, is it different for different heaters?
b. Is it possible for a DIY reset without calling a dealer? Many on boats are unable to physically get a dealer and the heater in the same place.
c. Is the counter reset when the heater fires up? For example after two false starts the heater finally jumps into action after the battery is charged, does the false start counter reset to zero or remain at two?</span>
Dear Mr DogWatch,
Re. Eberspacher Heaters used in the Marine Industry.
Your email was forwarded to Eberspacher UK Ltd by our dealer Espar. Please find my response to your questions as follows ;
1) Only the Eberspacher D1LC and some early D1LC " Compact" heaters produced between 1990-1998 have the "lock out" in the event of 5 unsuccessful physical start attempts (each attempt means two automatic starts to give the 10 starts before "lock out"). Should the heater start during these attempts then it cancels all previous non start fault codes.
Five new attempts are now available the next time the heater is operated.
However should the D1LC heater "lock out" after these five unsuccessful physical start attempts then you can unlock the control unit manually but this will only allow one more physical attempt at starting the heater. Should it then fail again, we recommend that you seek the services of the recognised Eberspacher dealer.
A visual indication is available to show the non start "lock out" or when an operational malfunction has occurred. This is by means of a flashing diagnostic code signal which is sent from the control unit. This signal is shown on the operating switch "LED" and consists of a series of flashes with varying lengths over a period of 8 seconds. The flash code signal is repeated until the heater is switched off with the operating switch.
The diagnostic flash code signals and one manual unlock attempt are obtained by switching on the heater and bridging between pin 4 and pin 6 on the operating switch. (round rheostat switch or square modulator)) or between Pin B9 and B11 on the electronic control unit. Remove the bridge after 2 seconds. Wait a few seconds until the error code is shown on the LED in the operating switch.
The flash code signal is deleted when the heater is switched off. It is therefore important to carefully check and note the flashing code signal that is shown before contacting an Eberspacher dealer to verify the diagnostic codes. Heaters after 1998 production and also the new Airtronic 2/4 do not have this "lock out" system.
<span style="color:blue">2. How important is the balanced flue? Is there a tolerance, if the exhaust is 1m does the air pipe into the chamber have to be 1m or is there a little leeway? </span>
2) The D1LC heater does not require a balanced flue. The maximum length of the exhaust pipe is 2 metres, with a minimum length of 0.2 metres This is in 24mm internal diameter exhaust piping (and includes in this length any silencer that may be installed). Likewise the maximum / minimum length of the combustion air inlet pipe is 2 metres and 0.2 metres respectively (again this includes any silencer that may be installed in this length).
The balanced flue was a requirement on very early Eberspacher produced heaters up to year 1990 and did not include the D1LC heater range.
<span style="color:blue">3. How hot does the exhaust get in general use? </span>
3) The maximum temperature of the exhaust pipe is 280 C measured 100 mm (4”) from the heater. Therefore it is important that the exhaust system is insulated with approved Eberspacher insulation material.
<span style="color:blue"> 4. Is there much the owner can do to provide long life to the heater, is there an annual servicing schedule, how often should glow plugs, fuel filters be changed? I realise as a company it might be your recommendation that units are returned to the dealer network for service, but I hope you will appreciate that this is not always an option for a boat owner due to location and more often than not, cost!
</span>
4) The owner can do much to provide a long life to the heater such as to check the following basic service schedule,
- All electrical connections
- Electrical cables with regard to damage caused by short circuiting
- Inlet and outlet ducting is not damaged or obstructed
- All fuel lines and fuel connections with regard to leakage
- Change fuel filter, which is integrated in the inlet of the fuel metering pump
- Check fuses
- Run the heater once a month during the summer period
A service schedule is attached for your assistance.
One area that does get overlooked until either the heater fails or the engine does not start is the actual fuel. It is essential that boat owners operate "good house keeping" where fuel is concerned. This is especially by keeping the fuel tank clean and clear of the dreaded fuel bug and any residue or water build up that can occur.
Eberspacher UK Ltd. are aware that there are fuel additives on the market that can be used to eliminate and assist in keeping the fuel clear and clean. Although some of these additives are acceptable for the operation of the diesel engine, unfortunately they can have an adverse effect on the operation of the Eberspacher heater.
Three liquid additives and one fuel line unit that we know will not effect the heater operation but can assist in arresting the fuel problem are as follows;
Liquid Additives.
a) 'Fuel set' Supplied by Liquid Engineering (UK) Ltd. Romsey Road, Whiteparish, Wiltshire. SP5 2SD. Contact. Gerry Yeatman.
Tel.01794 884963
b) 'Fortron' Supplied by Fortron Marketing & Distr. Ltd. 77/78 London Road, Dunstable, Beds. LU8 3DT. Contact. Graeme Campbell.
Tel 01582 475585.
c) 'Impala' Supplied by Impala Business Solutions Ltd. Unit 7, Gurnos Ind. Est. Bethel Road, Ystalyfera, Swansea. Contact. David White.
Tel 01639 841256.
Fuel line Unit.
d) 'Fuel Cat' Supplied by Fuel Cat Ltd. Park Royal Business Centre, 9-17 Park Royal Road, London NW10 7LQ.
Contact. Philip Brodie. Tel 020 8 933 2213
As commented on above, whilst these are acceptable for the heater we do advise the boat owners to contact his diesel engine manufacturer to ensure acceptance of any of the above before using them in your fuel system.

<span style="color:blue">5. Will the units run on paraffin?</span>
5) All Eberspacher heaters will run satisfactorily on paraffin fuel, there may be a very slight heat difference (lower) using this fuel. We would advise that you check for any regulations that may concern the use / carriage of this fuel on boats.
As with any manufacturer, we recommend that boat heater operators contact their nearest Eberspacher dealer for assistance when a heater fault occurs. Eberspacher UK Ltd can not be held responsible for any damage or accidents that may occur when the boat owner attempts unauthorised repairs to the heater themselves.
We have endeavoured to answer your questions and hope the above is of assistance.
