CH to keep a greenhouse frost free....??

[moorer]

HI all
I have an 8' by 10' greenhouse that I'd like to keep frost free. Having battled with filthy parafin last year I'm wondering if it's feasible to rig up a wet heating system powered by a solar panel (s) in the garden. Could I use a couple of old radiators lurking at the back of my garage and a small pump... just to keep my plants overwintered above zero. All ideas gratefully received.

ive run a power cable to mine and plugged in an oil filled rad, as this was the cheapest easiest option for me.
you could install your solar panel, pump, feed and expansion tank, radiator. it would work of sorts with no extra controls, but for the work involved wouldnt bother, that said if you really want to do it, go for it. good luck.

Bring the plants in the house.
