I have been pondering a cheap and efficient method of heating my new GH.

If possible, I don't want to use electical appliences as our power bill in winter is very large because we have a ducted reverse cycle air con going 24 / 7.

Gas heating I have been told dries the atmosphere, as does reverse cycle aircon. I was wondering whether a small kerosine heater would do the job, or would the vapours be detrimental to the plants ?

There obviously would be venting, but whether it would allow most of the vapours out, I don't know. I have a 12 volt fan going 24/7 for air movement already.

I JUST WANT TO HEAT IT EFFECTIVELY WITHOUT BLOWING THE BUDGET. I have already invested over a Grand in rebuilding the GH so far, NOT to mention plants that I have bought over and above that budget, and "she who must be obeyed " is starting to get twitchy if the "M" word is uttered from my lips.

Ok people I am open for comment, ridicule, scorn, sympathy, whatever.
