Espar heater

They make a pick up tube that has a tee fitting, that connects to your vent line. No drilling into the fuel tank

You are supposed to drill the tank, but I found this is on ebay;

Pretty simple, but unreliable. I got 2 units, used and almost new. When I was tired to fix used unit I managed to swap them. "New' unit was in working conditions just about a month then it fails again - error 52 'no flame detect'. Countless glow pin screen exchanges, cleaning, etc. - no results. The unit is still in non working condition.
I hope brand new units are working better, but as for now I can say just one word - complete disappointment.

 

Used holiday pause to dismount and complete disassemble the unit. There is one (or two) gasket you will destroy during disassemble ($15). Clean everything, rinse with paint thinner. Works again but time loss is irreversible.

 

We have a mix of Espar and Webasto and we absolutely love them. I have had one for 6 years and just like anything else there is regular maintainence that needs to be done.

 

Nicely engineered device does not need service every 3 weeks. Especially that dumb diesel furnace.

 

I just installed a wabasco and there didn't seem to be an option to t into the fuel line without buying your own fittings. I just used there pick up in an empty hole. Espar might be different. The hardest part for me was drilling the holes through the bottom of the truck and then bolting it on with a drive shaft and air tanks in the way. Also the wire for the fuel pump was to short for mine. I needed to make my own. Espar may have a longer wire, idk. It was a pretty simple install though. I'm no mechanic and I figured it out. Wabasco are generally a few bucks cheaper on fleabay.

 

thats the gasket you will destroy inevitably.

 

Mine doesnt need service every 3 weeks.
