How To Heat Your Greenhouse During Winter?

For those who live in extremely cold climates, you may need to take extra precautionary measures towards insulating your greenhouse. This ensures that your plants remain as warm as possible, so the outside cold does not affect their well-being.

Even though an immense amount of sun will filter through your greenhouse during the daytime, you can’t expect it to remain that warm when night time comes around.

In fact, if your greenhouse is uninsulated, you run the risk of having your plants freeze overnight the first instance that the temperature reaches below freezing.

A solution to this issue comes in the form of a heating system.


You should consider investing in an electric circuit heater that has a voltage measuring around 220-volts. Another option that may suffice is a small oil heater or gas heater, but these require a more thorough installation process.

To install a gas or oil heater, you have to set them up through a masonry wall, so you'll most likely need a professional to do this for you.

If none of the options above grab your attention, then you can opt out to use solar heaters. Solar heaters are uniquely designed just for greenhouses so that you won't run into any issues using them as a heat source.

Heat Lamps

You can also decide on installing radiant heat lamps along with soil heating cables, which are a more cost-effective method of keeping your plants warm during those harsh winter months.

You’ll have to hang radiant heat lamps over your plants to have them positively affect your plants. When you combine the warmth emitted from both the radiant heat lamps and the soil heating cables, you have a higher chance of growing a successful winter harvest.

As a side note, so your greenhouse does not burn down, you need to make sure that whatever heating system you decide on using comes built with an automatic shut off feature.

No Fuel Necessary Heating Tip

You can take additional measures to ensure your plants stay warm by placing rocks inside your greenhouse to absorb the heat of the sun. This heat will them get absorbed by your plants during the winter evenings.
