Ooh. 2 chinese heaters would get about that for £300 quid, different quality no doubt Though fizzy.I wish they did a bigger one. Eberspacher do a proper 8kw one. For about £3000

Well i have had over 5000 hours out of a cheap Chinese one so can't complain. Current 2 we use have been running 8 hours a day for 2 years now. Save me about £400 a month in electricity.

I've been using a military tent heater for a few months now. I changed the flue from the original to a 6" because thats where alot of heat gets wasted. I altered the burner settings to allow the burner to run on a lower setting. It uses about 25l of kerosene a week at 60p a ltr. Thats on tickover, I turn it up when I go in. My shed is 75m with lots of machines. It helps stop the rust. I ran it continuously for a month and then took the burner to bits. There was very little soot build up.

Yes I can definately see the benefit, first year I built my workshop I had 2 x 3 kw heaters running, £2 per hour, they had practically no effect at all when it’s freezing, a big heater to blast the area, then a couple of these wee eberspacher clones is the way to go in a larger area.
Especially when building control have insisted that so many air vents are required that I may as well be standing outside in the gale force winds, fecking tossers.

I’m paying almost double what you quoted for kerosine, but that’s filling a 25L container, I’m guessing you have an oil burner for your home heating, small volumes at least in Scotland is very expensive, no cheaper than pump diesel.
Scottish are rip off merchants. Rural garages in Wales charge around 85p a litre. Still too expensive.
You could buy an empty IBC for around £50 and order 1000L at a time.

yet they still havent learnt there lessonI wish they did a bigger one. Eberspacher do a proper 8kw one. For about £3000
otherwise we would be seeing eberspacher heaters within loads of sheds instead of the chinese ones we are installing now
Every British ambulance is fitted with an Eberspacher or Webasto. Every lorry. These people don't care about paying £1500 for something. Not their money.
I know a lot of money went into the design. But that was many moons ago. And no doubt they cost a bit more to make. But the markup they make is obscene.
Just spotted a Chinese one on Amazon for £60
I suspect it is a bare bones one but perfect as a spare.

As fizzy said, their markety isnt people sheds.
Its The OE manufacuters, fleet convertors, train builders etc. All these people need and demand engineering design and support/back up. And they give it. (been there, got that t-shirt)
The chinese manufacturers will give none of that, no (real) certification, no evidence of supply chain quality control, no ISO9001, 14001 etc, etc, etc. Their product is completely useless to those organisations i refer to above.
Eberspacher and webasto have no concern beyond each other. No lesson to be learnt.

No we use gas and woodburner in the hoose. Kero is from local fuel merchants who deliver my ovoids. They have a metered kerosene pump, you just bring your barrels or pay a deposit for theirs. At first I just got a couple of jerry cans and was surprised at the price. Then got 10, 25ltr barrels to get filled.

This thread inspired me to do some googling for indirect heaters other than cab heaters. I have no connection or experience with the company, but I think this would suit me quite well, and it looks reasonably priced. I would install the unit outside my workshop and duct in the hot air. This avoids having the fire risk and messy diesel inside the workshop and the complication of running multiple cab heaters.

If you don't want to leave a diesel/kero heater running unattended then put it outside. Significantly reduces the risk. The combustion intake and combustion exhaust should go outside, so you'd only need to route an intake for the heating air and then the heating air exhaust through the wall. Plenty of people have done this building little boxes on the side of the garage wall. You could even run two of 8kw ones o (iirc 5kw actual) on a bigger shared fuel tank.

I think my comment was more on heating capacity and that indirect 20kw heater are available and relatively cheap. The heater I currently have, regardless of whether it is a 5 or 8.5kw, only raises the temperature in my workshop by 5-7 degrees. This could be improved by installing some insulation, but having 20kw should make a big difference and would be more convenient for my usage case. I obviously have no idea how good these IDE20 are and if they are actually 20kw. I know many people enjoy homebrewing low-cost solutions, but for me, it is purely about convenience. If you only operate the heater for a few hours a week, the fuel cost is not really a significant consideration for me. Everyone has different circumstances, and the best type of heating varies depending on those unique circumstances.

I have done a deal on the large indirect Arcotherm heater in post #1. I know it's the proper job long term especially for my planned garage extension. It's rated output into the space is 30kw thereabouts so equal to 6x China heaters at full tilt. Of course I'll use thermostats, maybe even smart WiFi heating controls to operate the heater properly.
Planning to collect it tomorrow after work.
It'll burn alot of fuel but then again I suspect the rapid rate of getting proper heat up when it's required will still not be much worse consumption wise than a China heater running full tilt all day burning a gallon and still not making a proper dent in the temperatures.

This would be best installed outside in a small weather proof enclosure and pipe the heat output through the masonry wall and onto a louvre?
Only concern as such would be bringing in external atmosphere humidity (At certain times in winter / spring) to condense on the cars but maybe any vapours like that would go out the exhaust so no issue?
Having one pipe in does also have the advantage of positive input ventilation as such so would help counteract any small incoming draughts in use.

Buy an oil tank and get it delivered as if you have an oil boiler!
