banggood same heater: www.banggood.com/12V-5KW-Diesel-Air-Heater-4-Holes-All-In-1-LCD-Thermostat-for-Trailer-Truck-Car-p-1368620.html?rmmds=search&cur_warehouse=CNI looked at those heaters recently after doubleboost on youtube reviewed one for his machine shop. One thing to note though, I'd treat their power / fuel figures with a large pinch of salt. They claim that it uses at max 0.24 litre of fuel per hour, and given that diesel has an energy density of around 38MJ per litre, or about 10.5 kW per litre, I make it only 2.5 kW per 0.24 litre of fuel. Unless they are doing some magic to get twice the energy out of the fuel than it contains it's either only 2500w, or it uses 0.5 litres of fuel per hour They cover their rrrr'ses by putting 1-5kw on the side 😂 . It's a bit difficult these days with kilowatts,it was much easier with horsepower as the Oriental horses are a lot smaller, do less work and eat less. That quoted fuel consumption is probably on the lowest setting. That said though, it's not drinking it like it's an open bar and there is no tomorrow....

Am very interested in one of those heaters, do you have a link you can post & any idea of how hot the flue getts? I ask as my garage is timber frame construction with celotex insulated walls clad with cementatious panels external and ply/ plasterboard internally. The exhaust gets hot enough to burn your hand on. You can get fittings designed to go through boat cabins that are double insulated for want of a better description. Have a look on EBay, type in Planar Heater. Thank you very much for the reply and for the link too. I foresee a small project in my future. Would I be correct in thinking that the power supply on the cabinet is what powers the heater?

^^ Yes,you need a 12v source,either a battery or a powersupply. Once running,the draw is negligible,but on startup when it's heating up the glow plug,it's pulling about 10A. If you go down the power supply route,you need 12v 15A to give it a bit of headroom. I am running a 30A psu,but only because I had it...
Had it running last night for about an hour,full tilt some of the time as I was using it to dry some parts I had in the ultrasonic cleaner,( and it was -5c outside) . Kept turning it down between batches as it was getting too hot in the garage. Was very impressed with how little go go juice it used 😁

I know where I want to put the heater when I get it but I need to find a home for the motorcycle engine currently residing in that space............ Garages, never big enough are they!

Seen some good reviews & installations on you tube - got a couple more questions as a result. Did you drill another hole for the combustion air intake and have you installed a muffler on the exhaust? I really only have one possible location for the heater and the exhaust would be facing the flank wall of my neighbours house albeit screened by a 6ft fence, hence my concern about noise. I can walk between the side of the garage and the fence so I don’t believe I have any issues in regards to fumes and external combustion air intake if it is necessary to install the latter.
Have you played with the remote yet?

I've had a Chinese heater in the back of my Volvo for ages now, just set the timer and the car is toasty warm when I'm ready to go

Have you played with the remote yet? A silencer does make a difference. To be honest, they’re so cheap it’d be daft not to fit one. Personally, I’d have the combustion air intake from outside too, but I don’t think it’s vital provided you have adequate ventilation. Don’t forget the CO monitor.

Have you played with the remote yet? Yes I have added a silencer. They are about £13 so a bit of a no brainier to use it. It also comes with more 28mm exhaust pipe,which is a bonus. The exhaust gas is hot,I would suggest putting a heat shield up against the fence. At the moment I am drawing air from inside. I need to change a couple of things outside the garage before I can put the air inlet outside. Only time you smell kerosene is on start up,after that it's clean. Mine is the povo spec one, no remote 😂😂

Was very impressed with how little go go juice it used 😁 I use a 2.5 KW electric heater for a double (tandem garage) was single but I put a 5m x 3.5 m extension on the back The garage is well insulated (plaster boarded roof with 5 inches of loft insulation between the joists) and loft space is floored out on top Has a roller shutter door with insulated slats and both side access door and window are double glazed and half the garage shares a wall with the house and next doors garage It's always 6 deg warmer than outside temp in the winter and 6 deg cooler that outside temp in summer however it takes a good hour of running before the temp in the garage is comfortable in the winter ie 15-18 deg C I'm very interested in how effective you find this heater - I had considered fitting a large rad from the house circuit (benefits of a shared wall) but I didn't think it would bring it up to temp fast enough

Ian, in terms of space to be heated, I would say we are probably on par. In terms of insulation,you are better off than me. I have a double up and over steel door that is a heat sink of note. However,that said,when it's sunny,even in winter,you can feel the heat radiating off it. At the expense of a couple of sunny days in winter,I really should insulate it,as it tends to make the place like an oven in summer. I have the self adhesive insulation to go on it,have washed all the crud off one side,but it took ages to dry. Next job is to do the other side. Will be markedly quicker with the dehumidifier and heater running..😊 Without heating the garage might be marginally warmer than outside,but not a lot in it.
As for the diesel heater. Early days yet,but it's a huge improvement.It chucks out the heat. Filled the tank up with kerosene on Thursday. Bearing in mind this is probably the coldest spell we have had this winter,with ice and snow on frozen ground. Was in the garage Thursday evening for about an hour,Friday night for about two hours,Saturday and Sunday probably 4-5 hours. Heater running on full. It's used just on half a tank,so about 2,5 litres. If I hadn't been using it to dry parts,the chances are I would have switched it off Saturday Sunday after about an hour and a half. It's got a connector in front that you can attach four roughly 50mm pipes to. Originally I thought it abit gimmicky,but can see why it's on there. It does come with two bits of pipe. Got them facing opposite directions to each other normally running,at 90 and 180 degrees to the other pipes. It works well at spreading the heat about. I would be tempted to duct some of the air further around the workshop.The ducting also comes in handy for heating things up to dry or pre warm them for painting.
It's still early days yet,but am very happy. I actually look forward to going into the garage 😊 Again, it can be improved on. One thing that's very noticeable is the amount of heat wasted on the exhaust. It uses a convoluted 28mm stainless steel flexible pipe as an exhaust,that has already discoloured from the heat. It's hot enough to burn you after about ten minutes. If you buy the silencer separately,you get another length of this pipe. You need to try and keep the bends to a minimum,and as gentle as possible. I have purposely kept as much of this pipe in the garage,as this radiates a lot of heat too. Ultimately I will make a little heat exchanger for the exhaust and put a small radiator on the wall. It seems a waste of energy not too.
All in all, you cannot go wrong for the price. It warms the place up quickly and efficiently. I like the all in one construction of the one I bought,with the integral tank. It's a very compact unit. Quite remarkable..Running costs I have heard bandied about is that it costs about a third of what comparable electric heating would cost to run. Just need to find somebody that has oil fired heating that I can get oil at the 35p/l mark....😁

Another similar install - really impressed with the output / fuel used Is that a doorframe next to it? Whilst I can understand why you wanted to mount the heater up and out of the way,you are fighting thermal dynamics all the way with that install 😂 The top of your workspace must be toasty warm. 😁 Unfortunately the majority of your body is in the lower half of the building. Unless you have fans up in the eaves blowing all the hot air back down,you have a very inefficient set up there. Get a longer bit of pipe and duct the outlet right down to the floor where all the cold air is lurking,and you will be even more impressed with how it works 😁

Longer exhaust and silencer can just be seen here. Octopus arms good for drying duties 😂😂

We used to run our old diesel VW T4 on veg oil - when the local cash and carry was doing 20l for £15 and diesel was over £1.40/l at the pumps it made it very economical. Do you reckon these little heaters will run on veg (or a veg/petrol mix like I used to use in cold weather). Taking that thought further, can you legally run these on red diesel?

Yes,you can run them on red diesel. I think they will burn pretty much anything, diesel/ oil like. Only problem you may run into is the whole thing sooting up. Nothing a screwdriver and a bit of time cannot overcome. 😂 For the minimal amounts it uses, Kerosene is good enough for me,as it supposedly burns cleaner than diesel.

Like you the wasted heat from the exhaust bugs me. Loving what you do by the way, one of my must read threads

Red diesel is for all intensive purposes the exact same as clear just with a DNA marker and the dye, the only other real difference is that red diesels tend to burn cleaner due to the fact that the vehicles and engines that use them are also used indoors unlike petrol, from memory they have less sulphur content and at less than half the price whats not to like.

Being in the Midlands, red diesel is easily available at a lot of canal wharves as it's used on barges and as is said, about half the price of "pump" (we were using it for a generator - just had to sign a HMRC declaration at the shop that we wouldn't be using it in a road vehicle, as a one-time buyer).
Don't think there's many canals in East Sussex though - maybe boatyards?

Plenty of places to buy if you know where, Jonnys not far away from the River Medway, There are boat yards where I'm thinking of, Or go to Eastbourne its sold on a general forecourt just off the seafront
