PodOne Posted February 18, 2022 Report Share Posted February 18, 2022 True if the exhaust gases aren't vented to the outside. The dry heat of either electrical or water filled radiators would avoid this. That said having good insulation first is just as important. Quote Link to post Share on other sites

CO2 will do you no harm - you have 5% of it in your blood anyway! CO(1) is pretty toxic, but I don't believe in a sealed garage. A well ventilated one ( loosely fitted doors) will ensure no condensation and minimise the CO risk. The gas heater if properly adjusted will produce no CO, until the O2 in the space is used up!

Steve Priest Posted February 19, 2022 Report Share Posted February 19, 2022 I picked up one of these Corona paraffin heaters many years ago when it was on offer in B&Q. The fuel is not as cheap as it used to be, however it does kick out plenty of heat and small and light enough to move around the garage to where it's needed. https://www.base-camp.co.uk/Wick stoves lanterns & heaters/Corona picture.htm Steve Quote Link to post Share on other sites
Ralph Whitaker Posted February 20, 2022 Report Share Posted February 20, 2022 One of these self contained diesel heaters eBay item number: 294672202891 Neighbour has one in his shed, uses an old car battery on a trickle charger for power supply, though could be run direct from mains with a 12v adapter. Exhaust is routed to the outside through a small hole drilled in wall. Runs for hours on a litre of red diesel and gives out a massive blast of really hot air when run at Max (5kw) Benefit is it is dry heat, so no condensation that you get with such as propane heaters. Downside is it is not really movable once installed but air could be ducted around the garage with some suitable piping. Ralph Quote Link to post Share on other sites

Delivery within 3 days. I don't see a problem with that, our retail market is heavily populated with Chinese product and as long as the marketing firms haven't tried to skim too much from the manufacturers the Chinese can make product as good and better than many Western companies.

stillp Posted February 20, 2022 Report Share Posted February 20, 2022 Yes Mick, they can, but they often don't. I've ordered things in the past from some of these Chinese sources that have an address in the UK, and the goods have arrived withing the stated time, but direct from China! I don't know how they do it. Pete Quote Link to post Share on other sites
acaie Posted February 21, 2022 Report Share Posted February 21, 2022 (edited) Gas and oil fired heaters certainly are very effective at heating. As mentioned earlier, they do create water vapour in quantities which brings problems. This is someting I discovered when portable gas heaters were used in our church for a wedding, and the walls were dripping with condensation afterwards. So if you use a gas or oil fired heater that exhausts to your garage you will be warm but there will be water vapour and so condensation on colder things - like your nearest and dearest TR - in your garage. Dry heat prevents corrosion. Damp heat promotes corrosion. Edited February 21, 2022 by acaie Quote Link to post Share on other sites

Ralph Ralph, Why is the heat from a diesel powered heater dry and the propane heater a moist heat which encourages condensation ? Mick Richards Quote Link to post Share on other sites
RobH Posted February 21, 2022 Report Share Posted February 21, 2022 The diesel heater doesn't provide direct heat - it has a heat exchanger to the air and the wet exhaust is piped outside the building. A propane or a paraffin heater provides direct heat and all the wet combustion products stay inside. Quote Link to post Share on other sites

Extended the exhaust to 12ft ducted out the garage door and the blown heating is then ducted around the garage like on a boat. Fab bit of kit! Get a spare glow plug and gauzes if running red!

However, as my little garage is wide single, rather than a double, I only have to run the heater on almost the pilot light to warm the garage. Vented, and I never work with it on, too loud. When the heater isn't on, the de-humidifier is. In three years I haven't found any condensation on heavy hammers, roof cross struts etc, all excellent condensation meters ........just saying Quote Link to post Share on other sites

Have you had problems with running red diesel? I thought it was the same stuff but with a bit of red dye. I have just bough one, a 5kw, which only cost £65, and the seller was MaXspeeding Rods, well known on here. Don`t know how easy spares would be, but as it cost a friend of mine £250 to repair an Eberspacher diesel heater, as he said for £65 buy another for spares.

rog1 Posted February 23, 2022 Report Share Posted February 23, 2022 Hi Ralph, No, not personally as I haven't used red, however a friend had on his boat and had issues which led him to believe the difference isn't just the dye. He's gone back to regular diesel as it burns more cleanly. Similarly, for the cost of them, he bought another for spares, as your friend suggests. Regards Quote Link to post Share on other sites
harrytr5 Posted February 23, 2022 Report Share Posted February 23, 2022 Can it heat up a garage of 30 square metre's I wonder. My little fan heater takes some chill off but really inefficient. I put an offer in for the one linked by John and knocked off 99p. So £80.00 are they very good at heating??? I am so tempted. Regards Harry Quote Link to post Share on other sites

Ralph Trying a little thinking outside the box, considering the current Ukraine/Russia/Europe possible conflict and threatening power cuts because of inflating gas prices, if the worst happens I wonder if having one of these with a couple of spare 12v batteries might give a reasonable heat source for at least a couple of rooms in the house ?

Mick Richards The one fitted in my camper is brilliant, so as long as you could route the exhaust outside they would certainly heat a room. Ralph Quote Link to post Share on other sites
