A quick video of how I fitted the heater to my wife's garden office. How efficient it is, and how much fuel it uses!

The pump only delivers 0.022 ml per stroke and it depends on the presence of fuel for lubrication, so definitely a good idea to pre-prime such a large filter. hopefully you haven't caused too much wear on the pump running it dry so long. Overall, looks like a very nice install, assuming you have zero risk of power outages? Losing power while these are running will often result in a melted ECU, which is why so many folks use a battery hooked up to a trickle charger, this allows the heater to be used during an outage, or at least properly shut down with the cooling cycle. hope it holds up well for you! Any addition that gets the wife removing layers, is certainly a sound investment! 🙂

Cheers 👍 The pumps arrive wet, so have already had diesel through them, which should mean they were lubricated enough. We are good for power, but if we have an issue I'll buy a cheap pump and cannibalise it for parts! 🤣🤣🤣 for the wife comment 🤣🤣👍

I've had one of these maxspeedrods ones - worked flawlessly for the last 3yrs in my garage office - never tried any others but i'd say they are reliable and worth the money. I did add a filter for the fuel, expended the control wires - impressed tbh. *i'd suggest some small diameter round conduit pipe for the cables.. Merry Christmas fellow diesel heater person! (don't mess about with the settings advanced - it can change the values and numbers all get confusing so they are hard to work out how to put back!)

We get rodents in the garden, so I may add some conduit, that's a good idea. I think this company tweak the fuel supply, it's not smokey at all. But I have seen videos where people play with the pump settings. Happy Xmas! 🎄🎅

Nice modification to the cap good idea. Intereseting video. I like to see other projects which viewers have constructed as it gives me ideas. I wonder if these would run on Vegetable oil ?

I have now diverted the cold air intake into the office to make it more efficient. I have seen some videos where people run these on different fuels, but I would be worried about carbon build-up, etc. I'm quite happy to run a proper refined fuel to keep it burning clean. I'm sure a man of your ability could make something nicer than this, with a few 3D printed parts 👍

I'm fitting one in my flying club tomorrow. Inlet wants to be inside shed, just in case you suck in fumes from exhaust and damp cold air.. Had one in my camper last several years. Fuel can be drawn from top of tank. Saves risking bottom fitting fuel leak.

@MrDesmonick 6 ай бұрын

It works fine with the inlet outside. In a small room it would get too hot. The carbon monoxide reader sits at 0ppm, so all's good 👍 The O ring at the bottom tank fitting seals well, so there are no issues there. If I drew fuel from the top, I would still have to blank it off.

Diesel's about 10kWh per litre energy equivalent, so if all the heat of burning ends up inside the shed (it doesn't, that would mean cold heater case and cold exhaust), you're heating for about (£1.50/10) 15p per kWh which would be half the price of electricity. What other commenters say about recirculating the shed air - what you've done is nice, it's like PIV "Positive Input Ventilation", so the warm air pushes cold air around any leaks / windows / doors out to the outside. A rad on one side might cause the air in the room to 'roll', actually drawing cold air in through any leaks with the draught. Hard to argue with the outcome/economy until someone makes a heatpump at this price point. 5kW 'full tilt' should be half a litre / 75p per hour if my maths is right.

@MrDesmonick 6 ай бұрын

Cheers for the proper science! The main issue we have is the room is quite small, so gets warm pretty quick. I'm fitting another tomorrow to my Dad's summer house, and the plan is to recirculate the air for better efficiency.

@nlo114 7 ай бұрын

Fid a bit of roofing felt to cover the lid and sides, that ply will slurp up splashes and drips and will fall apart in no time. The fence treatment will probably not be up to the job. Allow a few inches overhang around all edges, so that the lid-felt overhangs the side-felt, and the side-felt has a 2 inch 'skirt' all round. Nice simple fit by the way 🙂

Interesting, I have often wondered how good these heaters are, and it was good to give some idea on the running costs, think I will fit one to my garage. I feel the cold nowadays, must be getting old.

@MrDesmonick 7 ай бұрын

I was genuinely impressed with the amount of real heat it kicks out compared to the fuel it uses. It would be even more efficient if the intake was also plumbed to extract 'warm' air from the area being heated. If it can live outside, in a garage the noisier fuel pumps wouldn't be an issue. If my workshop was more airtight, (the roof eves have a 1" gap to the walls for ventilation) I would be fitting one.

I started using one to heat the kitchen and bathroom this winter. I even use it as a hair-dryer after the shower 😅 Running it on 'red diesel' cost me about €1 per liter, so on the lowest setting this will last me about 10 hours... Will install one more for next winter.

Now youve blocked the air vent to the tank the pump is trying to pull against a vaccum in the tank, you do need to let air into the tank as you pull fuel out of it maybe loosen the lid a touch? you could lift up the tank to the height of the heater fuel intake, this would lesson the pumps struggle, I burn kerosene in mine bought from a fuel depot near oxford (Nolan oils) they will fill your own containers from 10 litres for you, containers available on e-bay. Hope youve considered buying a carbon monoxide alarm for inside the building as these heaters can draw in carbon monoxide from the glow plug hole which is exposed to the warm air stream pushed into the building. Nice build Ive built a plywood cabinet form mine and mounted it on the outside wall of our house and its saving a lot of heating the house in the winter time, it pulls air from our kitchen and pushes the hot air into the living room. you can silence the pump by hanging it from some 6mm bungee chord avaiable from B&Q. I think there should be a national effort to embrace these heaters and fit them to peoples homes to get us through the high costs of heating them currently. did you know a batch of the Vevor diesel heaters were seized by customs last january on saftey concerns?

@MrDesmonick 7 ай бұрын

Cheers, the cap is fully vented. The fitting is open, but means it now won't fill with water if it rains! We do have a carbon monoxide alarm, just in case, but that's a good shout. The box will do for a while, but might get better weatherproofing. The office gets plenty warm enough without recirculating the warm air, the wife lets it get to 28 degrees before she switches it off for a while! 🤣 Thanks for the comment 👍 and yes, I did see some heaters were seized. Apparently someone ran one of the suitcase types inside an enclosed space...🤦‍♂️

@middle-agedmacdonald2965 6 ай бұрын

Nice job, but I'm sure like others have said, it's designed to recirculate air vs introduce (pressurizing the house) air. The warm air in the house is pushed out through the gaps while "fresh" cold air is being heated from the coldest possible source. I wonder if it makes a difference? Seems like it's working well for you, maybe if I do it I'll not bother venting both ways either. I don't live in an extreme climate. I already use a swamp cooler mounted outside a window, so it's basically the same thing. I can literally throw one of these on top of that.

@MrDesmonick 6 ай бұрын

It's heating a small space and works very well with a cold intake. But the other one I've fitted will recirculate the air 👍

@JeffTurner15678 6 ай бұрын

@@MrDesmonick Agree, just bought the new 5kw unit with the Bluetooth controller my inlet will recirculate the warm air bit like a preheater. I did some rough fast calculations using 138,700 btu to a gal of diesel fuel and they claim 17,500 btu's with losses realistically one can assume around 80-87% combustion efficiency. Run some math and figure puts out about 15,000 to around 16,500 btu max. Which is still over 3x better than common electric heaters and way cheaper to operate.

If you have it source its air to heat from inside the building back into the building it will prove to be less chilly and more fuel efficient :)

Why is setup located outside the office area, guess here in USA puts risk of some yahoo stealing stuff, messing with stuff, and exposes everything to elements more. I have same type of power supply, think I will run a small UPS to unit to ensure if power goes out it will allow for my unit to properly cool down. I have a generator hooked up but it only protects house not my garage.

@MrDesmonick 6 ай бұрын

The office is in my garden so it is very safe. The box should keep the elements off for a while, but as others have said, it needs the top felting or similar. But yes, if it was on show somewhere public, it would be gone fairly quickly! A lot of people run a 12v battery on a charger, so if the power goes out it can shut down properly. It's a risk, but we have new power lines where we live, and cuts are rare unless it's in a storm.

@PainterD54 6 ай бұрын

I would use a steel box, never wood. You are trying to heat outside air which is not very efficient. Run another 3" vent from inside the building to the air intake (like cold air return on a furnace) much better to reheat the inside air than cold outside air.

@MrDesmonick 6 ай бұрын

Cheers 👍 The wooden box is fine right now and should last for years, but I'll keep an eye on it. I have since added a further intake pipe to the wall, so it now draws air from inside 😉👍
