Default Diesel Sprinter conversion air heater options and maintenance

I'm researching the Espar D2 and Webasto 2000 air heater options for our diesel NCV3 conversion, and I'm concerned about the hefty price tags and the annual maintenance that needs to be done.

1. What does the maintenance involve?

2. Are there cheaper but reasonably reliable options aside from Espar and Webasto? (Snugger, Happybuy, ?)

Depending on how or how much you use an Espar, the yearly maintenance involves replacing a $7 glowpin fuel screen which takes less than an hour to do.

Really? There's no need for cleaning other components or disassembling / reassembling parts?

Are those stories from folks who used the D2 at high altitude without the needed kit?

If anyone is interested, I have a very good connection with a dealer in Canada for the S2. About $800 delivered. PM me if you're interested.

2+ years of operating my D2 up to 8000 ft elevation and no maintenance required. Friends have similar experience.

Really.

You'll need to make or buy a 12mm 6pt deep socket with a slot in it to remove the glow pin. It has a wire permanently attached that needs to hang out that slot while you spin the socket. Be sure to install the heater in a location you can access occasionally without too much pain.

I managed to go 3 winters before needing to replace the screen. As it gets sooted up, the D2 will gradually begin to have trouble igniting: it will sound like a normal start-up but then abruptly shut off before trying to start again several times, usually succeeding on the 2nd try, and eventually the 3rd or 4th.

If at any point it just stops trying you'll have to pull the fuse to reset it. That failed starting behavior should give you plenty of warning that the screen needs to be replaced. I carry a spare screen in my glovebox alongside extra fuses (it's smaller than a grape).

Winter is coming.. just buy the damn heater. It was the single best thing I installed for comfort and livability- the fridge was a close second.

That sets my mind at ease. Thank you and OrioN for taking the time to share this information.

Also you need a 7mm tap to remove the screen. If you are careful, you can remove the screen, burn it out with a torch, and reinstall.

I agree, the D2 is the best, cold beer/fridge is second, and a hot shower are my top three.
