Hello Wood-n-things May be a bit late with advice! but over hear in England we can buy Halogen Heaters, Their electric each bar is 400watts small one has 2 bars so total power is 800watts, They are cheap to buy and run. Small heater cost me £10, The large one 1200watts costs £15.
If you accidentally knock it over it turns off for safety! So I hope this will help you and others, see you around. Bob
