Hi Peter

My "shed" is a "detached' double garage (no cars of course) and it is freezing in the winter months. I have tried fan heaters etc and like you found them pretty useless (unless you are in the direct hot air path). Thus, I am very grateful that you have posted the information here, and its an ideal time to by one for Santa to deliver. You mention silencers, but I haven't found one on the internet yet, do you have a link to where one might get a silencer for the unit.

Best wishes

Tim

Hi Tim. Tried to do a link but it didn’t work - go to Banggood.com and type in “diesel heater silencer” and you will find it comes together with a better air filter and tubes. Regards Peter

This looks like a good option if you only want the workspace heated whilst you're in it, the technology has been around for years in fact Saab used the same sort of thing to pre heat the cabin in the 9-5. If you need the space heated full time then it doesn't appear to work out that cheap; the heater consumes 0.2 litre per hour, red diesel costs 99p per litre, surely over 24hrs it's cheaper to run an electric, oil filled radiator?

Supertigrefan has a point. Fuel use of .2 litre an hour has no reference, to heat a rabbit hutch by y degrees above ambient, or the Albert hall. Or is it the maximum burn rate of the burner.

Just looking at this thread. I built my wooden shed about 17 years ago. It is from tongue and groove then a dpm and with 1" foam insulation and white faced hardboard. 5m x 3m x 2.5m at the apex. I originally heated it with a Calor gas fire but this only worked whist it was on of course and did not protect my glues and paints etc. The cost of the gas is now eye watering so I got an oil filled radiator instead and this can be left on all the time at a frost free setting for little cost overnight. I bought another smaller one as well and the shed can now be heated to a working temperature in about 10 mins. Compared with the cost of building models and heating the house this is minimal.

Hi all. Diesel heater Comes on at first and kicks out a whopping 5kW of fast moving hot air and as soon as the inside temperature at the heater inlet reaches your set temperature you put into the controller it reduces in fan speed and fuel consumption right down to a miser rate. That’s what I wanted - to be able to work in the shed in comfort for a few hours - with electric it just didn’t happen and it was too long in the cold and by the time it warmed up it was time to pack up. Electric never worked for me and now the wife has seen what it does I have had to order one for her craft cabin because she had exactly the same issue - but being a woman she turned the heater on about an hour before she went up there so that was about 46p down the pan before she even got in there. This diesel heater heats up your space very quick by hitting it hard with heat - no condensation just a nice warm environment to work. I just wish I had found out sooner. Regards Peter

Hi Martin - I tried a Calor portable fire in the shed but used it only twice because after finding my bench vice dripping with water I realised that one of the combustion products is water - and loads of it. I now have it for sale with an almost full gas bottle for £45 but don’t use it in your shed as your models will get mildew!

If diesel costs 99p / litre and consumption is 0.2 litres per hour, the cost for 24 hours will be 0.99 x 0.2 x 24 = £4.75.

Electricity cost about 15p per kWh. To compare eggs with eggs, you need to assume that you are using a 5KW heater. 5kW for 24 hours would be 5 x 24 x 0.15 = £18.

Even a more typical 2KW electric heater would cost 2 x 24 x 0.15 = £7.20.

I have assumed that both types of heater would be running at full 5kW output for the full 24 hours. In practice, both heaters would be thermostatically controlled, so the cost of both types would be much lower.

The diesel heater looks to be the cheapest option to me - by a factor of about 4.

P.S. Specs of the diesel heater linked at the top of page 2 of this thread say 0.1 litres / hour - not sure where your 0.2 litres / hour is from. It doesn't state what average output power this is delivering though, so I'd take all the figures with a pinch of salt.

Hi Gary. I was not too worried about the running costs myself as I just wanted something that would hit my shed hard with a lot of heat initially so I could work up there and the diesel heater fits that bill. I ordered up one for my friend Dave who now has his running and is also over the moon with his as he had the same problem that the electric just took too long. Wife came into my shed and demanded she should have one as well and I can assure you all the little lady is only concerned about results not running costs. And just to cap it all I can’t run a 5kW fan heater in my shed as the cables might be heating up as much as the fan heater... regards Peter

0.2 l/ph came from here:

So is it 0.1, 0.2 or none of them?

Who knows, but I'm willing to take the chance. That's my Christmas present to myself sorted.

Also ordered THIS silencer to go with it.

Hi all - recon once mine is up to temperature and the units ticking over at around 2+kW output at a guess the consumption is about .2 of a ltr an hour - either way I have been up my shed loads and only topped it up today with around 4 ltrs. I hope you (and my wife) get the heater before Christmas. Regards Peter

In my shed I have a oil heater running as an anti frost device. Keep the shed (13x8) dry. This is set to its lowest setting (no1 of 3) with the thermostat set as low as it can go. When its really cold, I have a 3 bar 1.8kw halogen radiant heater sat on the bench. I very rarely have more than one bar on. The fact is, my shed is far warmer and easier to keep warm that my brick garage that is attached to the house.

Hi Tim. Good luck to you for getting it at Christmas but remember that there has been a hell of a run of these this year. Most of the suppliers it seems take your money but can’t supply by the delivery date they give so you get a refund and start again which is why I went to Amazon in the end but that was my bad luck as many others got theirs with no problem so I do wish you good luck. Regards Peter

Some sellers on eBay are stating that it may arrive after Christmas however if they are stating a UK supply and taking your money knowing they have no stock I'd be tempted to use the "Report Item" facility.

I have a 5x8 metre timber framed shed fully insulated with 60mm Celotex in the walls and 100mm in the flat roof, floor is double layered 18mm treated board with a thin sandwich of radiator insulation.

I use a small oil filled radiator which is connected to my Hive network via a smart plug with various timer settings. For example during a weekday I have it come on for short periods just to keep the temp topped up.

With the remote access via the Hive app I can turn the rad on or off if my plans change. For a bit of fun I've put smart bulbs and a motion sensor in so all my shed lighting is fully automatic now.

I've got a decent size flat screen TV in the shed and once I'm in there between me, the TV and the kettle we generate enough heat to to overide the oil radiator.

Hi Devcon. Sounds like a great set up I have a very small TV in my shed which is very rarely used because while working there I don’t get a lot of time to look up but I do have the radio on good old Radio 4 almost all the time. My heating requirements were different to yours as I can’t plan a time so I grab anything from a couple of hours to an afternoon so as it’s all unplanned the only option for me is to either keep the heating on low all the time with a boost when I go in - which works out expensive or the solution I have posted here - hit it hard with heat so I can work within around 15 minutes at around 16c and climbing fast when it’s 6.8c outside... Different solution for same problems. Regards Peter

I had a ship-lapped 10X12ft wooden shed at my previous house which was freezing in the winter until I insulated it with celotex like Devcon1 has his. It made a remarkable difference and just a small electric convector heater was enough to make it warm and cosy. Well worth the time and investment.
