    Default Winter is Coming (apologies to GOT) .. How best to Heat a Workshop

    My workshop is 6.2M x 6.0M colorbond garage with a 3..6M high gable roof.
    The walls are lined with12ply and insulated ... there is insulation under the roof. The floor is concrete

    I currently have a 2400W electric fan heater .. but it warms only the air directly above it.

    I am looking for a better heating solution ... any suggestions. I am trying to avoid a wood burner or a kero heater.

    Thanks

    Rob

    How about a heated jacket....
    It would be the lowest cost form of heating. I had one until I gave it to my father in law in NZ.
    The idea is that you don't have to wear layers of clothes. Just a shirt underneath the jacket (you can wear pants too if you want

    The heated jacket suggestion is likely the best option, because even with insulation most Colorbond sheds leak air badly and space heating is quite wasteful. This is particularly the case where a roller door is fitted. The other consideration is dust collection, if you vent outside then the same volume of air has to come inside.

    The other method is not to heat the air but to make it feel warm.

    Infrared heating achieves this, you can get heat lamps like those that are sold for use in bathrooms and the more skin you expose the warmer it feels.

    You just need to have a lot located in many areas to make the whole room feel warm so I don't know how useful this would be for you.

    Maybe it's the location and/or the layers of personal insulation but I haven't felt the need for any heating in my shed for at least a decade. This is despite running the bigger DC which means the shed internal temp is the same as the outside air temp. In fact I look forward to those near zero degree mornings so I can run my mains gas forge and not suffer from over heating.

    I think we all may have have become too soft in terms heating.
    We used to sometimes use an open fireplace, or more often a gas heater most winter nights but when SWMBO developed multiple chemical sensitivities we were advised against doing this and got rid of the gas heater ad stopped using the fireplace and she started feeling much better.
    The idea was we were going to replace these with reverse cycle AC but financial restrictions meant it took us a while to get the funds and during that time we found we could get by just wearing extra clothing. We also found we slept better in a colder house.
    When we eventually got the reverse AC we decided not to use any heating for ourselves and only heat the house if we have guests, which is not that often.
    The internal house temperature gets down to a fairly constant 16º in mid winter and on the rare occasions where is dips below this we just wear an extra later of clothing.
    We are now completely used to the colder temps and really look forward to winter because we find we sleep better.

    Perth has a mild climate, being on a latitude further north than Sydney. It's not dissimilar to temps in Brisbane. Maybe you can bottle it and send it to Melbourne for Tahlee

    Up till now my shed has been uninsulated, but one thing that helped winter warmth was opening the east facing roller doors early of a morning and let the sun shine onto the concrete slab. Using thermal mass helped later in the day. If I was only there for a couple of hours though, keeping the doors shut worked better for radiant heat from the roller doors heating the air. I've toyed with the idea of hanging clear bistro blinds across the roller door openings to combine both, and it might also dampen noise through the doors.

    About 10kg usually does the trick.

    I was surprised to see the average lows for Melbourne are only ~1.7º lower than Perth, but the real difference is the average highs which are around 5º lower than Perth.
    As long as its not raining, Many Perth winter days are in fact quite glorious, cool enough not to sweat and really get some work done even in short sleeves.

    Machinery house sent an email to me the other day

    Needs LPG, but I'm guessing it would be cheaper to run that power, I'm sure someone can do the calculations

    Edit, i noticed a 9 KG LPG bottle has 441 MJ/h and this thing has a heat output of 54 MJ/h

    I got a Bosch 10.8v heated jacket last year and would highly recommend one; almost too warm at times but too cold to take it off in an open garage shed workshop...cheers, crowie

    Not really recommended for the average unventilated shed - the Carbon Monoxide will kill you quicker than you think.

    You could use ceramic heating panels. I installed them in the house after the cost of firewood passed the $100/tonne mark. They work like infrared lamps, radiant onto surrounding surfaces which then radiant the heat back. OR you could just take a break from the shed for a few months until the weather gets warmer...... I do, no amount of heating (that I can afford) can warm up a 6x9 shed during a Tassie winter.
