How to set up the thermostat of your greenhouse heater

Eden gas greenhouse heaters are efficient and require very little manual control, thanks to the included thermostat. The thermostat monitors the air temperature in your greenhouse and ensures your plants get the right amount of heat to thrive.

To improve the efficient operation and performance of your greenhouse heater, it's essential to carefully select where you position both the heater and the thermostatic probe. It's recommended to raise the heater off the ground by at least 30 cm to reduce the "cold strike" effect from the greenhouse floor onto the thermostat.

You also need to position the probe directly above the heater at the height you wish the greenhouse temperature to be detected. The best way to do this is to place a cane in a plant pot full of earth and put the pot behind the elevated heater. Tie the thermostat probe to the cane loosely with a cable or twine and move the probe up and down the cane.

The closer the probe is to the heater, the cooler the greenhouse will be. The further the probe is from the heater, the hotter the greenhouse will be.

Make sure the probe is not secured to anything metallic, as this will impact the sensor, causing the greenhouse to be hotter than the desired temperature and using more gas.

Please note that this is a mechanical thermostat. The temperature detected by the probe may differ from the actual temperature in the greenhouse by +/-3°C.

Safety tips for operating your greenhouse heater

At Hamilton Gas Products Ltd, safety is always paramount.
To operate your Eden gas greenhouse heater safely, we suggest you follow some simple recommendations: 

1. This is not a space or domestic heater. You should not use it in small and poorly ventilated areas, underground or in polytunnels. This greenhouse heater is also not suitable for caravans, campervans and motorhomes.
2. Make sure the heater is placed on a flat and stable surface, far from walls, furniture, curtains and other flammable materials, to avoid fire risk.
3. Only use propane gas and ensure the cylinder is always in a vertical position. It's also recommended to frequently inspect the gas hose for signs of damage or deterioration. The hose should not be bent or twisted and should be placed away from the heated parts of the unit.
4. Ensure to perform a leakage test using a specific spray product. Never use a naked flame. If the test shows a leak, turn off the gas cylinder valve immediately, thoroughly ventilate the greenhouse and call qualified personnel for help.
5. Do not move or touch the gas greenhouse heater when it's in operation or hot to avoid getting burnt.
