Just fitted an Eberspacher D4 cos others in the marina have D4's and love em. Can speak highly enough of it at the moment.
I have a D5LC hot air heater on a live-aboard boat. The blower motor consumed its brushes after about 7,000 hours (3 years). However you can't buy replacement brushes (which would be expensive at €10.00) because Eberspacher designed the hing backwards with the bruses at the end of the motor that you can't access. I had to buy a whole new blower unit at €600.00. This works out at over €200 per year in spare parts (when you also allow for a new glow plug etc) compared to an annual diesel fuel of €450.00. Eberspacher's ony response (given very politely) was that it was out of warranty, so it was my problem.
Apart from that I am very pleased with it. However if the blower motor fails again within the next 10 years I will look very closely at alternative makes.
I to have this problem with my eberspacher model d7L a1992 year model after taking it off and giving it to a eberspacher dealer to repair i was told it had a fualty heat senser and because of its age this part is no longer availableI bought a secondhand D1LCc on Ebay and fitted it at the start of a very cold winter week aboard.
Everyone appears to have their own opinion on diesel fired blown air heaters (usually based on their own experience). In that respect and after 4 years of faultless service I have joined the ranks of those totally sold on Eberspacher.
It's not true that you need an Eberspacher dealer to reset your unit, but you need to be responsible about it because it will have locked you out for a reason. The cause needs to be fixed before the unit is going to operate safely and reliably.
If you want to read about someone elses experience of fitting one of these (together with technical info) you may find this helpful:-

Unfortunately, it's a bit long winded but there's plenty of info there.
Eberspachers are fine - as long as they've been properly installed. That doesn't mean "professionally" installed, it just means installed according to the Eberspacher instructions. Almost all problems blamed on Eberspachers can be traced to poor installation.
Same thing here in the depths of winter: the saloon gets really toasty and the for'd cabin is a little chilly to put it mildly. Only really an issue when there's ice on the pontoon, but it may be worth figuring out how to restrict the main outlet. The only caveat on that is that if you get it wrong and put too much resistance in, the unit will overheat and shut itself down...Only real issue I have is that the owners stateroom is far away from the unit (in the laz) that the air goes the easy route first and warms up the after end spaces leaving the for'd cabin a bit short........a solution I'm told is to throttle the main saloon vent a bit, so to force more air for'd. Not done this as not really an big issue for me.
