Alright Stan......... not if you have economy heating... I use a 'frostfighter' and it costs me less than a penny an hour between 23.45 - 07.30... any other time it costs 28p an hour... :)
Sorry, should have said... atm I only have it on 'frost' setting, kicks in at 5c :)

I don't find them too bad but it depends on the size of area you want to heat. Lining the greenhouse with bubblewrap makes a big difference, as does wiring the heater to an external thermostat. I have mine set at 7c and it only has to kick in every now and then, even during this cold spell.

Yes, we've got a 2KW one, and frankly, I'm just not going to pay up to £50.00 a month this winter, although we're on Economy 7.
May put it on a time switch, and keep it at the temp I reckon is safe, it's well sheltered, and one end is nearly under a huge branch of an enormous yew tree, you'd be surprised at what a difference that makes.
We should really be putting more insulation in, but that's another £50.00 - it's quite a big greenhouse...

Right decision Stan, and let us know how you do it - did it...!

An electrical fan is way too expensive to have running...
12V car-battery can be charged for a low cost and can supply enough to keep the temp above freezing.

Unless the battery is charged by a hefty solar pv panel for free I can't see how that would work out cheaper.
Mains electric through heater is 100% efficient where as,through a charger there is a loss of efficiency.
Mind you, my poor old brain is suffering from wear and tear so may not be recalling things as it should ;)

our greenhouse heater is solid fuel wood or coal stove with heated pipes that run under benches i lit the fire as normal this morning as i was pot cleaning to keep me warm and heat up the greenhous i occasionally lite the heater in the winter when i am working in the greenhouse it was burning well then disaster struck the sound of running water
the boiler had developed a leak on the inner skin there was a hissing noise and then the fire went out
it looks like i need to get a new metal skin welded in the fire box before we start the growing season its a job i can't do myself because its a bit of a profecianal job
its the best heater i have ever had it had an inner skin replaced about ten years ago but nothing last for ever does it
that type of heat seems the best for my seed raising i found electricity was to expensive got a lot of white fly with paraffin again calor gas a bit expensive to run all day better at night when the other boiler goes down i think all heating is going to be expensive with fuel prices as they are this year
