Mine run on a 15A power supply, no issues what so ever.They pull about 10A with the glow plug on, so 15A gives enough head room

Made some progress over the last few days (excluding yesterday, of course!).
Made up an L-shaped bracket out of aluminium to hold the diesel filter and pump, as well as the power supply. I wasn't sure how to fit it as I wanted to be able to get it out relatively easily in case there's any problems, especially with the fuel connectors, so I ended up making wooden hangers for it that are drilled to take thin rebar - that way it's just a minute to pull out and reinsert the bars.
Not had the guts to drill a 30mm hole in the garage wall for the exhaust yet (plus I don't have a 30mm SDS drill so need to knock my neighbour's door to see whether he has one...).
Fuel tank is fitted but not yet plumbed to the heater.
I'll take it off again and get some pics of the brackets

Yeah - that's a recent "mod" as well! Previously, the press sat outside the shelf, face-on, but then I decided that was where the heater was going so it needed to get under the shelf. One multipurpose tool and a bit of bracing later...First pic. Ain't it a bugger when something's just a gnat's too tall to slide under your bench.

Hmmm... you think?
Suppose it would be a bit ironic (and fiery) if the heater melted the tank...
Good thought re copper pipe - I've certainly got plenty of it. Presumably there's no reason that the tank couldn't be 6-8 feet away?
No reason at all ,, they are that far in a lorry , and the ones in my boat were twenty five feet fron the tanks ,,, be an awful shame if all the heat from the heater was in the first three mins and the next two hours was from the workshop burning down ,,, Id also add a fire extinguisher by the door again jic , way easier looking at it than looking for it.Hmmm... you think?

Sold. I'll move it - cheers.
Doing surprisingly well for fire extinguishers! You'll just see the top of one to the left of the first pic and there's another one at the garage door.

Question for the experienced masses...
The exhaust is 25mm diameter and it's going to go through 250mm thick breeze block. I have a 25mm SDS bit so was going to wrap the exhaust with exhaust heatwrap up to the brick, but now I'm starting to wonder whether the brick will be ok with the ~300-400F exhaust going through it.
The alternative is to splurge £36 on a 30mm bit that I'll never use again and poke it through the brick with heatwrap all the way.
Any thoughts on whether the breeze block will cope with that kind of heat?

drill it in a clover leaf chip out the other bits and sleeve the hole , then put the exhaust through with some asbestos type packing to stop draughts ,,, probably not actually needed but its good practice.
I also tend to drill holes like that at a downwards angle too , if you can . Then if anything does go wrong unburned fuel runs out side and not inside , again probably not needed , but its as easy to drill at an angle as not. and it stops water running in from outside on wet days too.

Yep - had already planned to drill it down (inside to outside) to keep the rain at bay, but that point about unburned fuel ((shudder)) is also a good one

Had mine through the wall with a 25mm hole for 3 years with no problem at all.

Cheers for the advice re the exhaust.
I'm now thinking that it might be counter-productive to wrap it all the way to the wall, as that will just keep the exhaust super-toasty until it leaves the building. Instead I'm now thinking to wrap the first ~8" simply to protect everything else in close proximity to the heater itself, and then leave it naked for the rest of the run - partly for free heat as jsf said, and partly that at least some of that heat will get dissipated before it hits the wall...

Personally I'd insulate it to prevent condensate build-up due to rapid cooling, also have a bit of a drop on it to the outside for the same reason. Eventually the condensate will corrode the exhaust tube, letting combustion gases out in the wall or before it, a CO detector will help but you'll be getting unexplained headaches well before the detector is activated.

Look at previous posts regarding exauust a Lot of wasted heat, we vented it into a 150mm dia pipe I think it was 40 close to htr 6mts down pipe still 20, why waste it you paid for! it pipe wants to slope down to outside for condensation reason as mentioned
