Heating Your Polytunnel

There are several ways to heat a polytunnel, but some common methods include:

  1. Using a heat source such as a propane or natural gas heater. These heaters are generally connected to a fuel source and controlled by a thermostat, which maintains the desired temperature inside the polytunnel.

  2. Using electricity to power heating cables or mats, which are placed under the soil to warm it up. This is a good option for seedlings or plants that require warm soil to germinate.

  3. Using compost or other organic materials to create heat through the process of decomposition. The heat generated by the decomposition can be captured and used to warm the air inside the polytunnel.

  4. Using Thermal mass, Such as water barrels or concrete blocks. This method to absorb heat during the day and release it during the night, thus reducing the need for energy consumption.

The specific method chosen will depend on the size of the polytunnel, the plants being grown, the climate, and the available resources and budget. It is important to keep in mind that heating a polytunnel can be energy-intensive, so it may be necessary to use a combination of methods to maintain the desired temperature and reduce energy consumption.

It is recommend consulting a specialist or a horticulturist to get the right advise depending on the specific case.
