Diesel Heater for Garage/Workshop

Silver-Fox said:
You could put one in the garage of a Moho 😊
With a bit of exhaust pipe to the outside.

Wonder how much noise it makes 🤔😊

The normal ones that go in a motorhome are designed so that the connections for exhaust and air intake for combustion are out side the van, they sell turret kits to achieve that safety factor when fitting to thicker wooden insulated floors heater is sealed by a gasket . The cheapest thing to run all these heaters on is heating oil or kerosene according to the feed back on the Chinese heater pages these burn cleaner

Oh it works, just finished 20l drum of 28s kerosene from Rye oils. It suppose to burn very clean, and help with soot build up prevention. I’m back on diesel until next delivery.

I go to Rye oils as Mum lives in Rye. Get kero on pump for 65p a litre.
Runs well as you say.

Thanks, would they smell inside do you think and do they need 230v power as well?
My workshop really needs some decent heat.

Install the fuel tank outside your workshop and make sure the fuel line connection to the heater has a good tight seal, and you will get no smell of diesel.
With the exhaust venting outside of your workshop, again you will get no smell.
The heaters are designed to run on 12v other than a few which have a 240v option, and the easiest way is to hook them up to an old 12v car battery being charged with a cheap 240v battery charger.

That's interesting we often go through Rye MIL & BIL live in Lydd.
I looked on their website after Raul mentioned them, a 20 Lt container was over £28.

When I was a 15 year old we would put our overalls in the Trichoetholean tank, great dry cleaning fluid, then spin them in the swarf spinner.

Aye.... but of course we 'ad it tough..............
 
Fitted one of the “all in one” ones in my three car garage as the blast oil heater I used is both noisy and sore on heating oil. Have to say I have been a bit disappointed with the heat output from it but maybe just expected too much. The garage isn’t insulated and would easily be the same internal size as 4 Motorhomes, and with 2 cars in it acting as big heat sinks, it’s probably doing as good as could be expected. For £100 was worth doing, like someone said previously, I run it off an old car battery connected to an old charger but just not an absolute winner.

The Chinese 5Kw diesel heaters are a theoretical 5Kw but testing proves with loses that the output at full blast to be around the 4Kw, and expecting 4Kw (13,650 BTU) to heat a three car garage
I would have thought was more than a tad ambitious. :giggle:

Hi Lenny HB only just seen your post and a bit late I installed this off EBay.

Thanks John, I bought the one that can be powered from 12/24 & 240v. Arrived yesterday afternoon impressive bit of kit for 99 quid. Not got time to try it at the moment busy with another project for a couple of days.
 
For anyone fitting one of these that are not familiar. There is 2 air intakes and 2 exhausts.

The burner intake and exhaust must both be outside. This is where it pulls in air into the burn chamber then exhausts it out,
The heater intake and exhaust should both be inside, although with care you can have the heater intake outside as well but I don't know why you would want to. This air intake is sent around the metal body with fins on it and then exhausted into the van. If you this air intake coming from outside you run the risk of exhaust fumes coming back into the vehicle plus you are heating cold air and pumping it into the vehicle rather than adding heat to existing warm air that is already inside.

If you have the burner intake indoors, there is a chance of a backfire firing crap into the inside of your van/workshop, or when switching off you can get fumes coming back in. Also there is concern with strong winds blowing back in via the exhaust although not sure about that one.

These heaters operate similar to a balanced flue for safety reason.

I hope that all makes sense?
 
My air intake and exhaust exited my garage wall side by side and the products of combustion could be recycled into the air intake making incomplete combustion, so I bent a piece of 22mm copper pipe and fitted this to the exhaust and fitted the silencer to the end of the pipe.I also put a slightly downward bend on the air intake so that any rainwater would just run off.
I fitted the complete unit in about 1 1/2 hours.
John.

One thing to take into consideration is that the law on the use of red diesel is changing this April, whilst it can still be used for non-commercial heating and power, it's going to get harder to get as less service stations will stock it, so you might be running it on white in the future

I think Red can still be got from most marina's that supply fuel?
 
I have a large BRAND NEW Eberspacher (3 kw?) that I was going to fit to one of my Coaches about 20yrs ago, somewhere in the back of my garage that I can dig out and bring to the Bring & Buy & Bash and sell for about £120 IF anyone's interested??
(there might be a few SMALL parts missing that have been used on my other coaches but, as it cost well over a thousand pounds at the time, it should still be a bargain)

A local garage has a red pump, I will get a couple of liters to try it then fill up a can with Kerosene next time we go past Rye.

There used to be no difference between Red & White diesel except the colouring which allowed Custom & Excise to spot it in the tank easily. This the reason why, farm tractors could use either.
If this is still the situation, best to check?
 
Got a couple of litres of red diesel to try it out.
Just for a test I put the exhaust & combustion inlet under the bottom of the garage door.
It worked first time, turned it on and it went through the pump priming stage then fired up.
A bit disappointed with the heat output I only expect it to warm the garage not really heat after running a couple of hours temp in the garage only went up a few degrees.
The back of the garage is partioned off but the area to heat is still quite big, 18ft x 14ft and over 10ft high, no roof insulation external walls are cavity with 5" thermal blocks & the door is an insulated aluminum roller.
So I wasn't expecting it to get very warm and I had the door open 3 or 4 inches.

Air temp when I started was 8.4° the output from the heater never got above 49°, I was expecting at least 60° minium.

Noise from the exhaust was far higher than expected will have to get a silencer also need to get a longer exhaust pipe to get through the cavity wall, I can use the exsisting pipe to extend the combustion inlet.

Looking at a lot of YouTube videos a lot of the controllers allow you to tweak the fuel pump speed & burner temperature.

The controller is very basic does anyone know if there are hidden settings?

Sorry for disappointing outcome Lenny, I have the stand alone type like you fit in a van, garage is 9x5,5m and 3m high, with open vaulted ceiling. Still keeps warm, you can’t keep the hand in front of it at 3/4 load.
 
It will keep the chill off and was cheap, but looking a youtube videos others are getting 60° at the output of similar units.
I can keep my hand in front at full blast & your area is a lot bigger than mine.
Didn't help having the heater in front of the door with it open a few inches at the bottom so it was drawing in mostly air from outside may be better properly installed & if I can get the output temperature up it will probably be OK.

Lenny have you tried the arrows on the controls bye pressing the down arrow I slowed the pump down because it was getting to hot in my shed s it should do the same by pressing the up arrow

Hi Lenny my garage is 22’ 6” x 10’ 6” pre cast concrete with cement fibre roof, I insulated the roof with 2” kingsman, 2 x 1 framed the walls with double foil double bubble insulation covered in 13mm ply board new 7mm plastic tiled floor and my Chinese diesel heater is brilliant it’s the best I’ve bought for my garage and it’s a pleasure going in there.

John.
 
just looked at the picture and youve got the controller mounted near the outlets im prety sure that unit is a thermostat so if its adjacent to heat it will be cutting the output i assume it detaches to be mounted remotely as the other type of van heater would

Lenny, you have one of the new type controllers which have caused some head scratching as to how to get to the sub menus. I have been asked a couple of times about these new controllers as they have not come with operating instructions.
You will get more heat from your heater by removing the 4 port outlet and fitting a single 75mm outlet as the 4 port type obstruct and slows down the airflow exiting the heater so the heat does not have the reach.
With the 75mm outlet the volume of hot air is pushed further from the heater.

Confused by your temperature readings, are then in C of F as 8.4f is -13.1c :cold::cold::cold:
Were these room or heater temperatures ?

Edit : Twigged, are your temperature readings at the heater 4 way outlet ? Mine will be firing up again on the frost setting in a short while so I'll get a temperature reading from mine.
