Webasto coolant heater question

Regardless of webasto or espar, can you fire one up on a really cold engine and start it after a couple hours? Just curious what the good and bad are of the heaters, worth the money? Thanks

I have had both, espar gave me less problems, and the espar can be serviced without removal ( see video on YouTube). They don’t like bio diesel, you will have less trouble with a separate tank for kerosene, mine lasted 2 years. I would recommend a a bigger hydronic unit, like a DBW 2010 webasto, or proheat x-45, with a heat exchanger, as they don’t care what kind of fuel you use, and they can be plumbed into your fuel tank heater, and hydraulic tank, makes it like parking inside a heated shop. I get 12 hours of solid run time, on 4 batteries, and still have enough voltage to start the engine.

They tell you 2 hours to heat your engine with a webasto TSL-17 , but I found 1 hour in -10 with no wind would do it. My proheat x-45 only needs 30 minutes to start the engine, even at -20, but it’s 45,000 btu vs 7,000 btu output.

The smaller coolant heater will only provide enough heat to start the engine, it will not provide heat to the cabin, so you will need a separate heater for that, like a webasto airtop 2000, or espar D-2, so you will end up buying two heaters, One for the engine and one for the cabin. If you go with a bigger unit, you will need a low amp draw heat exchanger for the sleeper, otherwise your batteries will go dead rapidly.

I use switches for the tsl 17 instead of timers and the guys turn both on when stopping for the night. My thoughts is that it's easier to keep an engine warm than to try and heat it up. been running them like that for over 20 years.
