When winter arrives, nothing often sprouts in the greenhouse. Just theoretically! Because if you heat your greenhouse, you can also use it for growing plants in winter.

Popular BioGreen electric greenhouse heating

Winter is the time of year when the garden is quiet because there is simply nothing to do in the freezing temperatures. Everything is covered or covered with snow, so that gardeners really have no choice but to enjoy the sight of the snow-covered and perhaps even winterly decorated garden.

The same also applies to the greenhouse. While tomatoes grow here in summer, exotic fruit exudes its fragrance and herbs sprout, the greenhouse beds are often unused in winter. Unfortunately, because the temperatures in winter simply do not allow plants to be grown in the greenhouse in the normal way.

But we don't want to be satisfied with “normal”, do we? After all, there is always a way to get your will. For example, you can heat your greenhouse in winter and then still grow fruit and vegetables.

3 heating systems for the greenhouse presented

➤ electric greenhouse heating:

Anyone who has already thought about equipping the greenhouse with power connections when building or building it should consider electric greenhouse heating as the first choice. Plug the device into the socket suitable for wet rooms, switch it on, done. Quite practical, isn't it?

The good thing about electric heaters for the greenhouse is that they do not produce exhaust gases and do not require oxygen. This is how you protect your plants effectively from the absorption of pollutants that can arise during combustion. With an electric heater, you also ensure that the oxygen content in the greenhouse is not reduced too much. The only disadvantage: since these greenhouse heaters are operated with electricity, they naturally also increase electricity consumption.

Our tip:

If you only have a small greenhouse and want to heat it in winter, you should have a look at Here you will find electric heaters for the greenhouse, which are suitable for both standing and hanging installation. You can also conveniently pay for the electric heaters in installments.

➤ Gas heating:

Propane gas heating without odor pollution for the greenhouse (read more here)

If there are no sockets in your greenhouse, you can also use gas heating as an alternative. They are usually operated with a propane gas bottle and can even heat larger greenhouses (up to a size of 30 square meters). If a gas connection is available, you can also operate the gas heating with gas from the line and thus ensure an appropriate climate in the greenhouse.

The good thing about gas heating: around 99 percent of the energy used is actually converted into heat. This makes them very inexpensive and energy efficient. To do this, you must always check whether the gas bottle is still full or whether it needs to be replaced.

Our tip:

At you can find the Frosty greenhouse heater, which we can highly recommend. Why? Because it not only guarantees optimal heat distribution through the radiation grids, but is also thermostatically controllable (0-25 degrees) and also has an oxygen deficiency protection.

➤ Petroleum / paraffin heating:

Paraffin heating: good for small greenhouses (from BioGreen)

If replacing gas cylinders is too cumbersome, you can also use fuels such as Put petroleum or paraffin. However, these heaters are rather something for smaller greenhouses, since they do not come with a heating power as strong as that of an electric or gas heater. However, this does away with the connection costs that you have to expect with electricity or gas-powered variants.

You have to be careful that the heating is always supplied with fuel, but you benefit from a longer burning time with these models. So you have to fill up the tank much less often.

Our tip:

If you only have a small greenhouse, you can simply place several tea lights or a so-called tea light oven in the greenhouse instead of a petroleum or paraffin greenhouse heater. Instructions on how to build this small oven yourself can be found e.g. on


If you only have a small greenhouse, you should definitely resort to the cheapest option, that is, petroleum or paraffin heating. On the other hand, if you have a larger greenhouse, you should see whether it is cheaper to use a gas heater or an electric greenhouse heater. If there is already a gas connection, gas heating would of course make sense. If the greenhouse, on the other hand, is already equipped with sockets, an electric greenhouse heater makes more sense. If neither is available, you should rather use an electric heater because it ensures that the oxygen content in the greenhouse is not reduced too much, and you also do not have to constantly check whether the fuel is empty with this heating variant.
