Eberspacher recommend an annual service (2000 hours of use), or every 2 years for occasional use.
They recommend running the heater once a month to prevent the fuel gumming up the pump and pipes.
It may be better to service older generation heaters like D1L, D2L, D3L etc only when needed.
Eberspacher heaters are marketed as Espar in America and Canada.

DIY servicing costs
Servicing it yourself will be a lot cheaper, our pages show you how but only do it if you have the ability to do it safely.
Dealers obviously charge more, you are paying for their expertise, wages, equipment & premises etc plus they have to make a profit.
Our pages specifically cover Airtronic D2 D4 D5, D1LC, D1LCC, D3LCC, D5LC, D1L, D3. Other air models should be very similar to these.
Water heaters Hydronic D4WSC, D5WSC, D4WS, D5WS, D4WSZ, D5WSZ, D10 are also covered.
Service parts for the D2 on ebay 2016 cost about £11, plus £5 if you also replace the blower gasket.
Service parts for the D1LC, D1LCC cost about £30, plus £20 if you replace the glowpin.
Service parts for a Hydronic are about £37
You also may need to buy cleaning products eg Caustic soda. (Health and safety is extremely important with any cleaning product)
Take care when dismounting the Eberspacher, galvanic corrosion of the alloy ports can make removal of the pipes difficult and it can weaken the ports. Details of diy repair methods are on the Port repair page.
Annual Eberspacher maintenance can prevent many heater problems, typically failing to start when you most need it.
I can only give servicing details of models we have serviced ourselves or ones where people have sent us photographs and descriptions. Servicing of other Eberspacher heaters should be similar enough to these to enable you use them as general guides.
Please send us your photographs so I can expand the models covered and help others.
I provide this information service completely free but would welcome donations that I can use to buy additional models to improve the range covered, details are on the introduction page.
Eberspacher cease manufacturing spare parts after 10 years, thereafter parts will be available only while they still have old stock.
You use any information and advice I give entirely at your own risk.
If you do not accept this do not use this site, go to an Eberspacher dealer.
I have tried to make it as accurate as I can but accept no liability for errors or problems caused by following our pages.
Some of the information is only suitable for people with a good aptitude for mechanical and electrical repairs.
Any DIY involves some risk of accidents and you must decide if you are capable and can do it safely before carrying out any work.
You should also ensure your DIY is done to a professional standard in order to avoid creating potential hazards and insurance invalidation. Boat installations must strictly comply with Marine regulations.
