 Your greenhouse kit or your greenhouse construction will have provided you with an insulated environment for your gardening and plants. With glass, fibreglass, or other light attracting materials for walls, it is easy to think that your plants will have enough warmth for growth in the winter months. However, you actually need greenhouse heaters in many cases.

Although greenhouses are designed to allow heat from the sun into the greenhouse, greenhouse heaters are a mandatory supply for many gardeners. During the winter months when your greenhouse is buffeted by cold winds the heat from the sun will not be sufficient to regulate the temperature of your greenhouse. In these cases, greenhouse heaters will be necessary.

 If your winters where you live tend to send the climate to freezing temperatures or colder, you will definitely need to install greenhouse heaters to protect your plants from the cold. This will enable your plants to thrive throughout the winter months.

Unless you live in an extremely cold climate, you will not need to have very powerful greenhouse heaters. The insulation of your greenhouse should be sufficient to hold heat within the walls of the greenhouse. This should allow you to run your greenhouse heaters for a minimum amount of time each day.

Running greenhouse heaters does not take that much energy or fuel. You will only need to run your greenhouse heaters if temperatures drop to freezing or below, in most cases. You will also only need to run your greenhouse heaters for a few hours each day. The insulation in your greenhouse construction should be sufficient to trap the heat and hold it within the walls to enable the heaters to be run less often.

There are many types of greenhouse heaters available. The type of greenhouse heaters that you need will depend on the size of your greenhouse, the climate you live in, and the type of fuel that you prefer. Electric heaters are typically the least expensive, but wood burning or oil burning greenhouse heaters will save you money in actually running the heaters.
