I was in a new well insulated shop to lock at an air compressor for my brother. The building was 30X50 feet with a 14 ceiling and he heated it with two of those heaters he purchased on Amazon!

Yes he was using coloured diesel. The heaters would run about eight hours on a tankful. If I remember the tank held a litre of fuel, one tank on each heater. I think the only issue was noise out of the exhaust. He had them vented out of a window and he had to use a larger pipe, maybe 3 inch to make it quieter.

Hmm. Impressive. If you do a lot of your own oil changes you essentially could have almost free heat.

Sure, it's illegal to run it on waste oil in GB, but do you think people will care if they are freezing? Not likely.

 With the situation in Europe this winter I think a lot of people will be using unconventional fuels for heating. Years ago I had a garage heater that used engine oil. It worked well but was a pain to clean. 

Would it be possible to blend waste oil with diesel? Or would it simply gravity separate out?

Has anyone checked to see if its legal in your province? You may want to check with your insurance company before going too far.

So these little heaters are more or less what trucks have been using while parked for years now?

Like a Wabasto heater?

Pretty much. I watched a few videos on using waste oil and it looks like it can be a bit problematic to run with it straight however dilution with diesel or gas helps. I will likely just run it on diesel for the first little while.

 Bought one for the boat in Jordan River and I luv it!!! Just sips the fuel. Got the 8kw which is an overkill for the area in the boat. Tiny bit of smell when it first starts up but that might be because my exhaust is near a cabin window. Ended up buying mine out of Vevor for cheaper and they are base out of Richmond in Vancouver. Think it was 207.00 all in.       Tough Equipment & Tools, Pay Less (vevor.ca)

 

Just so you know: these wont shut off once temp setting is reached...they just go into a maintain low setting. So they are always running,but they come with a remote so you can shut it down by turning it off with the remote. Not the twin..mine came with remote on/off

I finally got my heater installed in my approx 10x20 home workshop. There was already a sturdy shelf/platform on the south wall so that's where I decided to place the heater. All I had to do was cut an access hole to allow the intake and exhaust hoses to pass through. If you install one of these ensure you allow ample clearance for the exhaust pipe. It gets quite hot and could cause a fire if it comes in contact with anything flammable. 

Here you can see the area below the shelf. The black hose is the intake for the burner. The metal pipe is for the exhaust:

 

For the exhaust I opted to splurge for a stainless through-the-wall exhaust isolator that's typically used for boat heaters.

The downside to these heaters is the instructions. They have to be the worst example of translation from Chinese I've ever seen! Thankfully there are Youtube videos that explain how to use the controller. The first step is to prime the fuel line by selecting a key sequence on the controller (Thanks Youtube!) to run the pump only without starting the burner. One primed you are good to go. There's a duct pipe you attach to the front blower output which must be attached since the ambient temp sensor is on the control unit. If you don't attach the duct warm air exiting the heater will skew the sensor readings

Right now the display screen is set to show one of 6 heat settings. H6 is the highest. After taking these photos I found a Youtube video explaining how to switch to temperature settings. it was 8c in the workshop when I took the photo. 

A wireless remote was included. Time well tell how well it performs and if it's as efficent on fuel as folks say. Right now I'm using a 12 volt power supply to operate the heater however if I like the performance of the heater I may invest in a decent solar panel and deep cycle battery to run it.

There's a fellow in Australia selling aftermarket controllers for these heaters that allow you much more precise control of the heater as well as controlling it with your cell phone via wi-fi and Bluetooth. With this aftermarket controller (called "Afterburner") you can fire up the heater and shut it down from anywhere in the world, set timers to automatically start and shut down, monitor fuel use etc.

 

 

 

 

 

My hope now that I'll have heat is to start organizing the place so that I have room to work. I want to put some steel on the walls and floor in one corner so I have a place to weld without burning the place down.
Maybe some day I'll insulate it!

Are they quiet enough that you won't need hearing protection long term? I mean just for comfort sake. I see some are mounting the unit outside the heated space.
