happybuy diesel air heater

Some have used the heaters on kero with no issues for a few year from their reports. Some use a mix of diesel and kero,some add a tablespoon of at to their tank.A few have had issues, many have not. Yrmv.
Maybe kero is slightly different in UK or Europe. I am amazed at the number of these heaters in use there. Just camping or are hundreds living in vehicles tiny homes???

Thousands actually. When we were in Ireland in 2003 there were people in Camper Vans and small RV's all over the place and they call them Travelers. They can park anywhere they want with some places having day limits but most do not. They all use those heaters there.

wondered. Was hesitant to ask on site in case I worded it incorrectly or they took it the wrong way.

Just don't mix any waste/used engine oil in with the diesel! The FB group is saying that if you do, it will definitely wear out the pump, and it will clog the burner's mesh screen. No bueno.

A couple have done it with "success", but I'm skeptical. A guy just tried it after warning not a good idea due to accelerated ash build up and sure enough it plugged rather quickly. I was actually surprised he shared his results.

John, specifically I was referring to the Eiberspacher installed by MCI in the '96 DL but have no doubt the Webasto and other years are all very similar. Don't know about the CDH units that run flat out all the time if they have any throttling mechanism. Could be different. Stands to reason they would get carried away with electronics and add PWM controls or some such just because they could. Newer is not always better.

On the contrary about the CDHs running flat out all the time. The led control & mother board controls the rate of burn from what is set on the controller. The fuel pump delivers a metered amount of fuel per stroke, the hotter the setting the quicker the fuel pump strokes. Once cabin temps are comfy the user dials back the controller to get a very slow & silent burn - this is when the diesel air heaters stands different that LP fired furnaces. They are truly awesome little units that are extremely simple by design and as efficient and HOT.

OK well that's an advantage over the OEM burners then since they are either off or on. OTOH, they use the coolant as a buffer. I think they can be pretty efficient also once set up properly to heat just the coach. Haven't thought of any practical way yet to use the exhaust heat though, since they are positioned behind the axles. Main advantages are that they are already in place and tapped into the main fuel tank.

Exhaust heat from a Espar or Webasto is going to hard to throttle they exhaust from 500 to 650 degrees lol I saw plastic hub caps on cars melted when people parked to close to the exhaust on Webasto running.There is no way you can compare the little heaters to a Espar or Webasto,they are just a cheaper alternative for people.Jim you can add electric elements to build you system with instead of running the Espar all the time,I use my system 70% of the time on electric.I see the boondockers in Quartzsite using their existing propane water heater with 2 pumps and heat exchangers heating their trailer or RV

I was contemplating on setting one of the following units (attached link) next to each CDH mainly for the remote fuel tank. Our son who is a firefighter suggested it after inspecting all the works. Just thought I'd share the info.

My Warmtoo aluminum jacketed CDH just arrived and I'll hopefully be installing it this week sometime. The names on these things are kind of humorous. I plan to use a marine type plastic gas tank for the diesel tank in lieu of the cheap tank that it comes with. It'll be nice to have some heat in the bus while doing the conversion. I only plan on installing one at this point, as I will also be installing an LP unit as well. It's nice to have diversified sources of heat.

I thought it would be beneficial to mention it wise not to wire a CDH to a distribution panel so the power to the operational heater can't be inadvertently disconnected (catastrophic results) during operation. Our CDHs are wired directly with in line fuse to the battery bank. Fwiw

chessie4905 · December 17, 2021, 07:11:09 PM

Also with disconnect switch in case of temp sensor failure draining batteries because fan won't stop running.

dtcerrato · December 17, 2021, 07:21:29 PM

10-4 on a disconnect. I'd pull the fuse.

Very good to know. I'm sure it would not be a good idea to have it shut off without it having first gone through its shutdown sequences. Thanks!
