    Default Propane greenhouse heater

    Hi peeps,

    I've just purchased a greenhouse heater - a Lifestyle eden 2kw propane heater.

    I have an 8x12 glass greenhouse which I plan to use it with. I appreciate its on the small side, but can insert a partition (or similar) to only heat what is required.

    I do have a useful very low cost supply of propane with which to experiment with which should be helpful.

    My initial plans are to try to establish how much it will cost, to keep the area frost free (so min 4 degrees). Initially to get a head start in Feb/Mar/Apr as we've no south facing windows and SWMBO doesn't like seedlings and potatoes on east and west facing windowsills.

    Then in the future there is the possibility of continuing to grow certain crops right through the winter (salads, some brassicas, etc) that will struggle to actually grow in a cold greenhouse.

    Does anyone have any tips? Ideas? Thoughts? that might help me.

    I'm aware that minimising heat loss is equally important as getting the heat going in, so will be making sure the GH is bubblewrapped when heating is required.

    I don't know the answer but I'm keen to find out too!

    Realised over the last few days my greenhouse isn't as 'frost free' as I thought it was! As a result our dining table is covered in seed trays as the shallots and broad beans I was hoping would germinate in the GH don't stand a chance!

    I've got the same heater, and used it to heat a 6x12 from March through May, keeping it to 10c which is what tomatoes prefer. That was in a largely uninsulated plastic covered g/house. I had a mid-sized gas bottle (19kg) and it lasted through the whole time.

    The main thing that I found difficult to get right was the ventilation - the heater will shut off if there's too much build of gasses, so you need to make sure that some clean air can get in near to the heater. Because mine was plastic covered, I just put a small slit in the bottom and put a piece of drain-pipe through it which was enough.

    Also, I'd run it for at least a week with a max/min thermometer in the place your plants will sit, and check it every day to see what sort of temp you're maintaining. Aim for the high side, because the thermostats aren't the world's greatest...

    Thanks for that, thats great. I've got a couple of min/max thermometers so was going to monitor it for a week or 2, and also monitor what the outside temp is. And have also read that ventilation is important so very useful information.

    I'm definately going to use it for a boost from March to May, and yes a minimum of 10 degrees is what toms need, so will aim for that in those months.

    Perhaps only testing this time but will, monitor the temps throughout end of Jan and Feb, to perhaps use it all next winter for increased production, and overwintering.

    'Go outdoors' are quoting about 30 on their website, with lots of others online around the 35 mark. It may be possible to find a cheaper local supplier.

    Supposing you ran it for the complete 3 months then that equates to about 30 pence a day. Obviously there are lots of variables, but to keep a greenhouse at 10 degrees I wouldn't say thats a large amount - although without a comparison to electric it could be really expensive!

    That's what I found TLO. Electric isn't an option at the allotment, and the paraffin was both expensive and smelly...

    Having changed my set-up on the allotment, I'll be testing and then using the heater in an 8x6 glass greenhouse this year, so I expect the gas useage to go down a bit from last year
