Having read the glowing review of these and having not been very impressed with the electic space heater alternatives, I've hit buy on one of the 5kw units and a silencer from an ebay seller, which is promised to be delivered this week.

I'm assuming that I have to arrange for the exhaust to exit the building and don;t really want to drill a 25mm hole through the stone work, but could take it out through the perspex glazed side frame of a door. I thought I'd replace one panel with timber with a neat hole and fill the gap with something fireproof/heat resistant. Any guidance on suitable materials from those who have installed these exhausts through shed walls and the like?

Mine exits through concrete so insulation wasn't a problem for me but the heat is significant. I used a 22mm Yorkshire elbow to turn it outside for the silencer to lay along the wall and it melted the solder in it.

Been following theses for a while and now it's cold decided this year to try one, order placed so hopefully this week, my question is weather anyone has installed this outside and pipe the warm air in to the shed? Clearly it would need to go in a weather proof box but would the cold effect it?

Temperature regulation might be a problem - they appear to measure the inlet air temperature to sense when to switch to low output.

The exhaust pipe does get really hot so drilling a hole through the brick would be your best and safest option removing any worry of damage to door frame or possible fire . You can buy extra lengths of exhaust tubing quite cheaply.

A good sealant for any joins or filling in around pipe and brickwork would be car exhaust putty that sets hard when heated.

If I had the room I would run the exhaust through an old radiator that would act as a silencer and give extra heating that would otherwise go to waste .

Looking at Peter's videos he is running the exhaust out through the wall of a timber shed, with some sort of hear resistant lagging around the exhaust pipe. I'm guessing that when these are used inside vehicles the exhaust must exit somewhere?

My workshop is stone, rather than brick, with very thick walls, so drilling an 25mm diameter hole through there is something to be avoided if at all possible. I doubt that there is 25mm clearance in the mortar between the stones.

Great idea on the exhaust heat recovery. I've got some heater matrices that'll be just the job for that.

As long as they aren't soft soldered - exhaust temperatures are high enough to melt joints...don't forget the importance of gas tightness - there's the possibility of carbon monoxide poisoning to consider.

Just suppose you direct your exhaust gas via a heater matrix and forget to turn you heater off or run it against a high heat load (very cold outside), just how hot will the matrix get?

Not as per manufacturers instructions, no over temperature protection and your shed burns down....I think it will be a very one way conversation with the house insurers.

Anyone considered why the exhaust gas gets that hot? I would expect its for a reason of the manufacturer would be using that heat to improve the efficiency of the unit.

Using the water coil around the exhaust and pumping that. I'm not brave enough to run exhaust gases back into the shed.

Could you use Kerosene in these heaters, i think it would burn cleaner, and be more readily available, i used to buy it for me turbines from the petrol stations when i lived in Cyprus, i suppose its the same here ????

Still haven't seen a decent alternative for getting the exhaust out to the outside without drilling a tricky hole through a >2 foot thick stone wall. I'd hoped to be able to take a single pane out of the glazed door and replace it with something similar to the no-longer-available heat-resistant and non-conductive asbestos sheet that used to be readily available. Haven;t seen anything of that sort for years and the local Wickes had nothing remotely suitable.

Are you planning to use a lead acid battery for the diesel heater, or a mains power supply? It will need to be 12v/20A. I tried using an old car battery but it couldn't supply the amps so the heater auto shut down. I use a power supply now.

The exhaust on mine simply goes through the hardboard lining, polystyrene insulation and the wooden outer. No problems.

Wow. i ordered my heater on the 14th December and was told delivery would be on the 20th January

But it turned up today, how good is that, so now im waiting for the power supply to arrive

Im going to run mine on kerosene as i think it will burn cleaner

SR 71 - Yes, Kerosine is a better choice than Red Diesel if you have access to it.

Do you think that there is a price advantage over red diesel? I could only buy this localish for 99p/l. When I had a turbine I had to travel a long way to get kerosine but cannot remember the price. My heater works just fine on diesel at 125p/l.
