Hi.
I'm looking for some advice /help in choosing a heat source for our greenhouse.

the greenhouse we have is a dig geodesic dome covered with polytunnel polythene. It has a diameter of 6 meters and is 3 meters high.

We are looking to utilise the area more during the year and use it as more of an indoor garden/ chill out area. A nice spot to have a glass or 2 of vino or a bottle of beer in he evenings. The only problem is it gets a bit chilly at nighttime. So we have decided to heat it. But there are a lot of options.
I don't think passive heating alone is enough to have a comfortable temperature. Seeing as we are heating it I plan to keep some tropicals out there to. so we are looking for ideas and pros and cons of supplemental heat.
Initially we were thinking of buying a wood burning stove but there would be a lot of work keeping the fires burning.
Out other options are gas or electric.
Does anybody know how much it would cost to run either. The gas heater would be run on cylinders.
I have priced a 4.2Kw gas heater online and it is pretty reasonable but I'm curious of the running costs before I commit to buying it. I'm not sure if I am aloud to post the brand on the forum.
Otherwise would anyone know roughly the cost of using electric.

Thanks for your help

What you are asking is very technical and the correct answer depends on a lot of variables. My best advice to you is to seek professional advice from a heating engineer. My gut feeling, without knowing any of the technical information, would be to opt for gas, something similar to those patio heaters.

Gas could poison you inside as carbon monoxide builds up, any naked flame will melt the plastic, electric will cause condensation in plastic so you will get soaked and possibly electrocuted. My suggestion would be dig a very deep hole and use Geothermal heating energy, so you will have nice tropical plants, nice ambience to sit in and collect your own limes and lemons for the gin and tonic.

Heat pumps are about the same price as a small car.

Cheers for the answers. Problem with the geothermal is that the water table is very high so I would end up digging a pond. While it's not a bad idea I have my better half on board with this plan and a giant pond might scupper that........ Unless i sold it as a Venice experience 😂

Second hand oil burner (One from people changing to condensing boilers) heating a couple of second hand radiators inside. No pollution to air inside then and you'll be nice and comfy.
