When winter arrives, nothing sprout in the greenhouse. Just theoretically! After all, if you heat your greenhouse, you can also use it to grow plants in winter.
Winter is the season when the garden is quiet because there is simply nothing to do in the freezing temperatures. Everything is covered or snowed in, so that we gardeners have no choice but to enjoy the sight of the snow-covered and perhaps winterly decorated garden.
By the way, the same applies to the greenhouse. While tomatoes grow here in summer, exotic fruit exudes its scent and herbs sprout, the greenhouse beds often lie fallow in winter. Unfortunately, because the temperatures simply do not allow for normal plant cultivation in the greenhouse in winter.
But we don't want to be satisfied with "normal", do we? After all, there is always a way to get what you want. For example, you can heat your greenhouse in winter and still grow fruit and vegetables.
3 heating systems for the greenhouse presented
➤ electric greenhouse heater:
Anyone who thought about equipping the greenhouse with power connections when building or assembling it should be the first choice for an electric greenhouse heater. Plug the device into the socket suitable for damp rooms, switch on, done. Handy, right?
The good thing about electric heaters for the greenhouse is that they do not emit any fumes and do not require oxygen. In this way you effectively protect your plants from absorbing 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 downside: since these greenhouse heaters are powered by electricity, they also increase electricity consumption.
Our tip:
If you only have a small greenhouse and would like to heat it in winter, you should take a look at www.biogreen.de. Here you will find electric heaters for the greenhouse, which are suitable for both standing and hanging installation. Furthermoreyou can also conveniently pay for the electric heaters here in installments.
➤ Gas heating:
If there are no sockets in your greenhouse, you can use gas heating as an alternative. They are usually powered by a propane gas bottle and can even heat larger greenhouses (up to 30 square meters in size). If a gas connection is available, you can also operate the gas heater with gas from the mains and thus ensure an appropriate climate in the greenhouse.
The good thing about gas heaters: around 99 percent of the energy used is actually converted into heat. This makes them very cost effective and energy efficient. However, you must always check whether the gas bottle is still full or whether it needs to be replaced.
Our tip:
You can find the Frosty greenhouse heater on www.amazon.de, which we can highly recommend. Why? Because it not only guarantees optimal heat distribution through the radiation grid, but can also be thermostatically controlled (0-25 degrees) and also has an oxygen deficiency protection.
➤ Petroleum/paraffin heater:
If changing gas bottles is too cumbersome, you can use fuels such as petroleum or paraffin as an alternative to gas heating. However, these heaters are more for smaller greenhouses, as they do not come with such a high heat output as that of an electric or gas heater. But there are no connection costs, which you have to reckon with with electricity or gas-powered variants.
Although you have to make sure that the heater is always supplied with fuel, 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 using a petroleum or paraffin greenhouse heater. Instructions on how to build this small oven yourself can be found e.g. at www.kreativ-bastelstube.de.
Conclusion:
If you only have a small greenhouse, you should go for the cheapest option, i.e. use petroleum or paraffin heating. On the other hand, if you own a larger greenhouse, you should see whether a gas heater or an electric greenhouse heater is cheaper. If there is already a gas connection, a gas heater would of course be requiredsensible. If, on the other hand, the greenhouse is already equipped with sockets (note: don't forget the socket fuse!), an electric greenhouse heater makes more sense. If you don't have either of the two, it's better to use an electric heater, because it ensures that the oxygen content in the greenhouse is not reduced too much, and with this type of heating you don't have to constantly check whether the fuel is empty.
