Solar Panelled Greenhouse heaters

[knot]

anyone had experience with these any good?,

No I havent....sorry.

This has made me laugh though! Why were you thinking about these at 8.24am on a Monday morning???

cos we have had a frost this morning so i think some of my stuff will have suffered. i also stopped myy husband getting a paraffin heater as i didnit want another job of having to fill it up and now am feeling guilty
