Any shedworkers? Need advice on heating my garden office

[IreneNesser]

This is the first winter of my garden office, and sadly dd's sleepover guests wrecked the heater (Ds' sleepover, OTOH, left it unscathed.)

I need a nice, very quiet, small heater which will heat the shed office quickly. No poisonous fumes, etc.

Any thoughts, please?

Basic Fan heaters are usually good. Or you can get oil filled radiators that are good.

If it was me I'd get a wood burning stove. Very warm and if you get the chinmey installed no fumes :)

OH uses an oil filled radiator in his bunker - slow but cheap

What about those long tubluar ones that go on the floor. Sposed to be v cheap to run (electric) and as its plugged in - you can put a timer on it to come on an hour before work.
I had them in my conservatory and they worked well.
