I know you chime in about your perfect Espar system often. It is appreciated.
What you need to understand is that you aren't helping by making us feel like we are crazy, wrong, or unlucky. I've had my system gone through a half dozen times at this point.
It isn't like 1% of us with constant issues with these units. It is much higher than that. My contact said closer to 1/3 of folks with Transits with this system are dealing with the issues that seem to have no instant solution.
I've gotten comments from people enough that I park away from folks and with the exhaust pointed away so no one else needs to hear it.
Sorry for chuckling... I know you're not crazy or wrong; you and others have done the installs as well as anyone else.
I appreciate the feedback. I don't doubt the problems AT ALL. I'd say we just got lucky - meaning unlucky for you and others, I guess? I've read the threads of some of the problem installs and it's clear there's something wrong. I sure don't know squat about how to install these; I'm not even sure we did a good job following the instructions.
I'm curious which issues you're having: loud exhaust? That seems normal - ours is loud as well. The loud pump? I just don't hear ours but I'm curious if that's a "lucky" pump as well? But the cases where they just don't work... that is seriously troubling. Altitude or otherwise. The cases where the stand-pipe didn't resolve issues? Or the cases where the stock gas line works fine at altitude? So weird.
FWIW, if we had issues, I'd go with one of the cheap Chinese diesel units since there's more possible resolutions there. In theory, these units are all nearly identical and I think the down-side to the Espar and Webasto units at this point is they don't have the huge user-support-base that the cheap ones have. There have been altitude adjustments and fuel-metering and external control and SO many other great options for these for years. I just wish there was a gasoline version that worked with the Afterburner controller.
Heat is essential for our usage. I'd have removed the Espar and replaced it with /something/ or our van would be useless half the year or more.
Man... a third of the installs? That would be insane if true: the most expensive air-heater is far more failure-prone than a $100 Chinese diesel unit? That would /really/ suck. Heck, I'd install two of those thing if that were my only option. It's the diesel tank install that sucks, not installing the units.
