Flueless Stove (gas)

[FONT=&quot]Looking at one these as option to heat a conservatory.

Would have low usage - couple of hours, 2/3 evenings a week.
It seems like a lot easier option than going with tradition mult-fuel stove, as that would need hole in wall (or roof) for pipe.

With the GAS one, it just needs to be turned on. But I'm concerned about GAS fire burning oxygen, and it causing condensation.

Anyone have experience with these stoves?[/FONT]

But it will have ventilation requirements, so you may need to have 2 holes! hi/low vents

From what I can see these would have the exact same pros and cons as a Superser, ie condensation and not expecially cost effective to run. Gas in small cylinders afaik is about 20% more expensive than using an electric heater.

Thanks for updates....

Not very positive, would like to hear from someone who has one? anyone?
