Going to be starting a few things off after the next cold snap. Was thinking about a calor gas heater for the greenhouse, the type that folk use at home. Seen one in the local charity shop £15. Any thoughts? anyone done the same?
yes, but be carefull of the carbon monoxide get the heater serviced, i have my window open a very tiny bit just to let the fumes out had mine running for a week now and i gave it a good clean i also have a monoxide detecter in there and no sign of it yet :) but its a warm 20deg, no signs of plant life yet but its warm at least i can get warm in this cold spell been down this morning and brrrrrrrrrrrr -1 wind chill.
I would have thought it far too expensive to run and possibly too hot for basic needs.
too expensive to run, as eristic says!!
any Co2 would be a bonus for the plants, though! ;)
I also agree with it being to expensive also another bad point it takes the moisture out of the air.
On low i'm sure a bottle would last 3months easy,so long as i turned it on at dusk and off at dawn(ish). I need to do something because the wifes warned me already about the windowsills. I've tried parafin that was too expensive.
Ever considdered a Bunzen Burner
You mean like what they use in schools? No if when why and what? Oh and how much?

A 15kg bottle burning on low for 6-8 hours a night lasts about a fortnight. Current cost of gas is <>£27. Until my radiators are fitted, I rely on one of these to heat my study room/office.
Thanks for your suggestions. The frost buster looks the one £50 + £5 delivery
In the corner of my greenhouse I have one of the plastic mini greenhouses with the plastic cover and 5 shelves, about 15-20 quid. I put all my seed trays in there and have a 586 Cold Frame Heater in the bottom of that. It keeps it well warm enough and a gallon lasts literally yonks.
It'd cost me a fortune to heat the whole greenhouse, a 6x12 lean-to that's 8 foot at it's highest point.
