greenhouse heaters

[kavanaru]

interesting all this discussion and the differences between "both sides of the atlantic"... I am currently also doing some research for GH heatings, and has been advice that gas should be avoided due to "negative effects" on the plants. Even though electricity should be the NO-NO-NO (due to heating costs) in most of Europe, it seems to be the most appropiate system to be used in France.

I have also been advice to build with a floor digged ca. 50 - 80 cm in the ground, as this would help to regulate temperature (kept above 0°C in winter, but cool in summer)

what i am not very sure yet, is whether the floor should be made out of concrete, or just the ground covered with gravel...

Ramon, wouldn't gas have a negative effect on the plants only if the heater wasn't vented or am I missing something or is there something I don't know about?

no idea, Becca.. it is just the general advice I have foudn here... I think I need to check for both vented and unvented heaters and check the differences... however, in my case it seems that in France (yes, I am planing moving to France and buying a house there) it is cheaper with electricity than anything else...

i would be afraid of power outages in the nite if i had electric....we get frequent power outages in the winter months which make electric untrustworthy.....the non-vented heaters are designed to be used indoors so i doubt that there would be any of the problems of excaping gas fumes to damage either the orchids of myself.....gas heater technology has come a far ways from the old days....then you only had a choice of boilers for heat....

does anyone have any good links to look at and price greenhouse heaters or other types of heaters that can be used in that setting.
