I have a small 6 x 4 poly carbonate lean-to greenhouse which I have bubble wrapped inside. As we have hardly had any frosts this Winter it has stayed over 10-15 degrees without a heater. I have been looking at the small paraffin heaters as they seem to last a long time on a tank full.

I will be sewing the usual peas, b beans, salad etc. The question is, will a heater give me a head start and if so, which one is best for this size ?

Thanks.

TBH if the temp inside is that high, you would not really need any form of heating for sowing the seeds you said, in a few weeks' time

But wouldn't it give you a head start with other things like toms etc ?

I bought what I believed to be a quality well known brand of paraffin greenhouse heater, it turned out to be a oriental made cooking stove according to the pidgin english instruction book,whilst it worked well for a while, once it started being troublesome much to my ire I found that the only spare parts available from the importer/supplier were wicks.  .
So if thinking about one made by a company begining with P check the spares situation.
That said I bought a second hand Eltex double burner greenhouse heater for £4 and have found it reliable and spares available should the need arise, have also found it to be more economical than the oriental jobby.

I find it hard to get parrafin for the heater and weed burner and wish I went for gas for both. I think a bit of warmth is Ok to get a head start but you have to keep it up until its realy warm or the plants seem to go slow and stop growing for a while. May be even fall behind later plantings

Been and Queued  stock paraffin........... but it's around £7 for a 4Ltr bottle.

I switched from parrafin to electric mainly because of easy access to electric points, but when I used to buy my parrafin, it was either via a local allotment society that bought it in bulk which made it a lot cheaper, or if they had none I used to go to a local oil depot, who always had tanks full of the stuff, still way cheaper than B&Q though 
Check Yell for oil suppliers and make a few calls, I'm sure they will be able to help you..
