All of our gas greenhouse heaters run off propane gas which means they are more economical to run day to day than paraffin greenhouse heaters - our range of gas greenhouse heaters come from trusted brands such as Lifestyle, Bio Green, Proheater and Hotbox. Our most popular gas greenhouse heater is certainly the Lifestyle 2kw heater - economical, accurate thermostat and at a fantastic price.
