This is another example of what a reconditioned or very good working Eberspacher D2 should work like.
These are one of the most popular heaters in use today, but when buying one of these. You really need to know it runs like this one!
So, ask your seller why it is for sale and does it smoke or pop at all?
A tiny bit of smoke on start can be normal, but should dissapear within a few seconds. Continued smoke will be of concern or a popping sound from the exhaust. Sometimes it may just be the glow plug screen and requires a decoke that may not be as easy as it sounds!
Heaters that have not been serviced for years, often have seized screws that hold the flame tube in place. Their heads strip very easily and leave you with a big problem that can take hours to get over even if they don't damage the casing threads.
A replacement heat exchanger and burner costs nearly £300 new!
So take care when buying a second hand heater.
