happybuy diesel air heater

I think Espar generally refers to the controller. Not the same company as Eiberspacher who makes the burner I don't think. Maybe one is German and the other is Canadian? Something like that anyway.

could you put heat exhaust wrap around the length of the exhaust pipe and muffler to make it a little more safe like we do on our exhaust pipes in the bus to let the engine compartments cool a little?

We're totally reclaiming the exhaust heat by keeping a warm main engine fuel tank and warm wet tank compartment bottom utilizing the heat from exhaust so no insulation wanted here! Toasty in the cold morning after a night run...

I plan to buy this one in January. I cannot find any information or reviews at all so I will be the guinea pug I guess. I would have bought it already but I am waiting for free shipping for the 12 volt model. If anyone has experience with them please let me know. I have an old Wanderlodge with factory heat exchangers so it should be an easy install.

It's interesting how the add (from the link above) states "Webasto type" unit. Seems like an proprietary advertising legal issue! I plan to see if I can't fix my original bus Webasto water exchange unit. It probably hasn't run for several years (it didn't work when I bought the bus). At any rate, I still plan to pick up 2 of the CD air heaters.

WoW, you can't buy the control box for a Webasto for what these peeps are selling an entire boiler!

The world continues to be a most fascinating place...!

Happy coaching!

They've gotten carried away with their control boxes. Right now I have mine hooked up to a simple $10 thermostatic switch that I bought online. That's fine for house heat. Not the best solution for engine preheat, but a toggle switch or a timer will do for that. As for maintaining coolant heat on those cold winter runs, again a cheap thermostatic switch will work. No real need for those overly digitalized $500 control boxes.

does that allow for proper cool down of the components?

[dtcerrato]

We just ordered a control with remote for CDHs for $16 straight from China a little over a week ago. Ebay said it should deliver before Christmas. I received it a couple days ago! Airmail straight into our mail box free shipping! How the heck can you beat that? I'm a patriot and dislike communism but I gotta say some of the best world class shopping is straight from China - we did it to our selves... Rant over - carry on.

There are actually international postal agreements at play here, and the Chinese vendors have learned to use them to their advantage. It's actually cheaper to ship items from China straight to your mailbox than to ship the same thing from me to you. For whatever reason no administrations have seen fit to fix this in spite of cries from US vendors for years, and it was part of why I decided to shut down my wood shop a few years ago. They were able to sell competing products to my customers and ship them to their doors for less than I could buy the raw materials. Didn't make sense to turn the lights on any more. Doing my part to help you rant.

Here is a great video showing fuel pump cutaway and how it works. Gent is showing his idea of reducing pump clicking when operating.

Control boards are easy to repair on name brand heaters I never paid over 10 bucks, parts are usally 50 cents to a $1.50 where they get the price for new boards is beyond me. Just about any kid that got a Heath kit for Christmas can repair a board unless the chip is bad   

[richard5933]

Isn't a Webasto control box just an electronically controlled bunch of relays? I'm seeing people online doing custom control boxes from Arduino boards and relays. Not much magical about them.

[luvrbus]

There nothing magic,I know the gent that started Dinosuar he repairs about any type of control box for me,he repaired my Coleman AC controls (3) Coleman wanted wanted $185.00 ea for, he repaired mine and found the weak link the price was $45.00 plus $15.00 shipping lol and he wasn't happy about the $15.00 shipping fee

Oh for the love of...
It's a two wire on/off control. A simple toggle switch is all that's required to run it, not even that. You could use a paper clip or clothes pin to stick the bare wires together.

OEM was more complicated because it needed a timer to preheat the main engine. Do you need that? Not really, you can time it yourself. Your phone has a timer with a beep.

So any cheap thermostat will do just fine. Like I said, ten bucks or so off ebay. Or one from a yard sale for a dollar. Doesn't have to be fancy. What exactly is it you are paying for with that extra hundreds of dollars? Programmability so you don't have to turn the heat down at night and up in the morning? What else do you have to do that you can't spare 5 seconds out of your busy day?

I've read that kerosene will shorten the service life of the fuel pump as it doesn't get lubed as well with the thinner viscosity. They were designed with diesel #2 fwiw.

[chessie4905]

Jim, you're  not talking about the Chineese furnaces are you with just an on off switch?
