I have a 10 X 6 leanto fixed to my shed. I have a tubular electric heater with a thermostat. I keep the thermostat at it's lowest position ( 4 degrees C). This just provides a frost free greenhouse. I overwinter Geraniums, Fuchsias and Cacti. Keep everything on the dry side.
I used to use bubble wrap and no heating, but in a severe winter some of the Cacti died.
I over winter any biennials which aren't quite ready to plant out in there. If you grow sweetpea's, depending where you live in the country, these can be started off end of September/October time and will survive even the most harsh winters without heat.

Thanks for all you ideas hopefully having the GH will ensure I have lots of nice early plants next year.
How about some winter lettuce ? sow now and it will survive in a cold / frost free GH
I also bubble wrap / fleece depending on what I have in the GH.
