Off brand diesel coolant heaters

Does anyone know ANYTHING about these guys (retailer or manufacturer)? This is a 12K (41k BTU) diesel coolant heater. for $550. Name brands are double that. Kinda nervous about buying from something that looks so shady. Would rather order from something that looks more like a store front but was told Alibada is legit at least.

For sure there is a lot less info out there about the off brand coolant heaters vs the air heaters... People are installing the air heaters in everything from skoolies and boats to pickups and vans to garages and cottages. I saw an initial review video of a combo air+water heater the other day but you can't really compare a 5KW air+water unit to a 12KW water one.

Alibaba is a legit marketplace just like Amazon is a legit marketplace... but that doesn't imply anything about the quality of the product you're buying. I'm not aware of anyone with a coolant heater that isn't a name brand unit.

Looks similar to a webasto unit I just fixed for a guy. I'm sure it's just a stolen design that some place in china is mass producing, screwing over a legitimate company.

The one I fixed had a control unit in the cab that operates the heater, so make sure it has that or it's no more then a paper weight.

I've been using a 5kw unit for about two months and it has worked like a champ! I think that I paid around $130 for mine.

Mine is not being used for living space heating, but is being used to warm my FLA house battery. I had been having problems with capacity due to the cold weather. Problem solved!

Also, it is very efficient on fuel usage.

$130 is either one hell of a used deal or air.

I recently picked up an air heater for $110 with all the accessories.. but it's an air heater, not a coolant heater. They're a dime a dozen.

Yeah, before I went this route I figured the coolant would be 2x the air. So much for that idea.

Sounds like what you describe is a diesel AIR heater. This thread is about diesel COOLANT heater. Huge price difference between the 2.

Water Heater

Ive been looking at one of these also but I was planning on using it in conjunction with a marine style water heater. Use the diesel heater to heat up the water heater tank. Eliminate the on demand unit i have installed. The goal would be to try to only need one fuel.

Next would be a Wallas or Wabesto diesel cook top.

For the air heaters, yes. For the name brand coolant heater, yes. For the knock off coolant heaters, NO.

And hard to make suitable for HWS-only in summer.

But redundancy is good, all the diesel ones really like running flat out not throttled down.

My desire to fuel with gasoline is an even bigger challenge

Yeah, I'll probably do a smaller loop for that.

My Corvair had a gasoline heater.

The gas heater on Ricky Nelsons C-47 airplane killed him.

I don't know about the knock offs. My genuine Espar has four heat levels. The knock off looks exactly like it.
