Got one of these down the shed, works way better than the old halogen heater I had as it heats the air properly. You need decent ventilation, but thats hardly an issue for me.

I use one in my 4sq metre conservatory and it enables me to use the conservatory all year round.
I was also expecting to get some condensation but because the kitchen door leading into it is always open it's never a problem.
Another thing is these new modern heaters don't smell fumey like they used to and seem to burn very clean.

Good price, if I needed one this is what I would get. Good find Op Heat giving

Smelling fumey might be a useful sign to warn of danger... Not to be a killjoy but unless your ceiling is 5mtrs tall then you might want to read this
From Manufacturers website:
SAFETY INFORMATION.
This is a fumeless heater. Ensure the room is ventilated while the heater is in operation. Do not operate in a bedroom, caravan, boat, tent, awning or any room less than 80 cubic metres in volume.

How long would one gas bottle last please...let's say how many hours on a medium setting...
Trying to work out if this is worth getting as apposed to electric

These heaters have three heat settings and if used on maximum for a prolonged period of time I would agree on the 80 cubic metres volume.
I find in my conservatory on the maximum heat setting it is way too hot after a few minutes so it always gets used on minimum and I also have a carbon monoxide alarm in the room for extra safety.
Even on maximum the carbon monoxide alarm has never once gone off plus the heater also has an auto shut of if oxygen levels get too low which they never have.

Perfect. That you so much

Great price!
