Cheap Amazon Diesel heater recommendations?

[smritte]

That's what I'm trying this weekend. I wasn't successful when I tried it before but its possible I did it wrong. I had read the difference between the 2.5k and 5k was that setting. A 2k would actually be ideal for my set up.

@smritte The only issue with the HZ setting is the heater runs all the time, but at a constant flow rate. I know mine runs at about 1-2 amps once it is warmed up depending on the setting

This is the best video I found on changing settings, it covers the 3 most common controllers How to Change Your Chinese Diesel Heater From Hz to Celsius - Three Most Common Controllers - Bing video

An additional note the combustion air intake has a cheap silencer rather than and actual air filter. Cheap ATV/small motorcycle filters have been used for fliters.

Still looking for a good option for the "furnace" air intake. I f Ican find a 3d printable snorkel hood, I can add an actived carbon filter.

Would something like this work?

@Shahn I would think so if it is dry - just remember as few bends as possible on the furnace intake airline and exhaust

That's funny. I was actually in Granger catalog looking at those but didn't find one in 3 inch. Good job

Good to know that these would work, was curious if the flow resistance is to high or not.

@smritte As for possibly filtering the furnace air intake Pipercross has nice foam filters that apparently filter silt dust but now personal experience, and yes the silicone hose is definitely pricey but the best solution and will last a long time

So I checked the current draw during heat up today and the power draw in watts, watts is a little bit higher because of the loss of the power supply, even though that might not be to much.

The highest current I saw during start up sequence when the pump was pulsing was 9,2A and something around 150W.
Didn't take pictures from everything...
Current was max. 2,5A while running on H6 normal heating operation, using about 50W (I assume it's not very precise here...)

 

[smritte]

Just to make sure I got this.
Peak current with glow plug on was 9.2A
Running on high fan was 2.5A

Your controller is the same one I have. What heater do you have and are you able to change the HZ for the fuel pump?

Yes you got that.
You are talking about some advanced settings? Like changing the ratio Fan speed / pump frequency? If so, no idea didn't try that.
The Vevor 5kw aio has the same controler than this one but this is a generic unit I got from a ebay seller with local stock.

@MazeVX Take a look at eth video below it shows how to switch to hrz

I'm quite sure that this is the other controller, they look almost identical but are completely different.
This video describes the controler I have on both heaters

 

[rgallant]

@MazeVX that is wild that they have different functionality

Yep, I was really close to a nervous breakdown when I found the video I posted... But then eventually everything made sense and miraculously started working

 

[smritte]

From what I've read, there's several versions that look like the ones you posted. Number of fan blades, color of temp readout. What's even better, some of them are not completely compatible with the heater their supplied with. You could look up your controller and not get certain functions. From what I read on that aussy's site, (the one who makes the nice controllers) the heaters are almost all the same, the internal control boards are not. He shows eight or ten diffrent control boards with two or three compatible with his controller.

I recently built one of the Amazon diesel heaters and installed it into an apache 4800 case and I'm truly impressed with the heat output. Still figuring out all the settings.

I thought I'd share my exhaust setup, I don't believe anybody has tried this. I installed one of the new muffler/silencers into the case and cut the backside of case out. I built an exhaust pan out of aluminum to incase it in and it worked out nicely and no heat issues at all.

Now to create some duct work in my rooftop tent.

 

[smritte]

That muffler cut out is great. An issue I've had with mine is a small breeze kept changing direction and blowing the exhaust back to my intake. I'm going to elevate the intake and put a small filter on it to keep powder dirt out.
Nothing like diesel smell in the morning to get your heart started.

I used one of these on the combustion intake, it is a hair big but a 1 inch copper coupler and some duct tape sorted it out. Still looking for a solution for the cold air intake.

[smritte]

Not the combustion intake, the fresh air intake. The filter will have a three inch opening. Out here we get powder silt blowing around. I also occasionally have the breeze blow the exhaust back towards the same.

@smritte that one I am struggling with - I am looking at 3d printing a snorkel hood and adding a filter that way. The filter is the issue so far.

 

[rgallant]

@smritte I am going to try this one
It should work ok, I need to pop my RTT and heat it so I can give it a good test as far as code throwing.
