View Full Version : 2005 sprinter [not Webasto] Eberspacher Heater

Can any one tell me if there is a way to get my Webasto Heater to fire off without running the engine. It would seam it is only there to help boost the heat to the van. But it would be awsome to have it work with van off. If not is there a way to make my van run at high idle to not hurt the things, charge faster, and run the Webasto?

theres a number of threads to do this with espar's (thanks vic, --dick, et al) - scroll down thru the T1N sections, you'll find em.

Here is the write up I did.
This is for the stock heater booster (Espar) and running on a ‘house’ battery.

I’m not sure if that is what you are trying to do.

If it truly is a Webasto brand heater I don't believe that it would be a MB OEM installation.

If it is a aftermarket Webasto it probably just needs to be connected to a always hot 12 VDC source.
