This new greenhouse heater fills a gap in the market for a reasonably priced 3kW greenhouse heater.

3kW models are ideal for 8x12 greenhouses and above. Depending on the outside temp and the desired temp. in the greenhouse, you could use a 3kW heater in a greenhouse up to 10x20 in size (for frost free)

In order to be safe for greenhouse use, new regulations state that greenhouse heaters should be IPX4 rated or above, meaning that if they encounter some wet conditions or splashing they should be safe. This model is IPX4 rated.

Unlike less robust heaters, this model has a full metal casing, powder coated in an attractive green colour.

You can use this heater on a fan-only setting (for summer use) or 3kW fan heater where the integral adjustable thermostat will click off the heat once the desired temperature is reached. We recommend using your heater together with a max-min thermometer to help you to set the thermostat to your desired temperature.

The 30W fan circulates an impressive 305m3 per hour ensuring that the heat can be distributed as widely as possible within your greenhouse, helping to keep the temperature nice and stable.

Q. Does this heater work with normal household 3 pin plug 13A?

A. Yes, all of our electric heaters work with a normal household 3 pin 13A plug.

Average rating: (5)

by Stuart Brown

Very pleased. It seems robust and has kept the greenhouse at > 4C during the cold snap, so the thermostat is doing its job.

by James Arscott

Wonderful and robust. Strongly recommend this. But, a big but, be sure your greenhouse power supply can deal with 3kW. Bog standard wiring usually can't. So seriously consider 2kw option instead.

by Tim Justham

Robustly built and has two thermostatic controls, one for temperature and an overheat function to prevent damage to the heater. Others fans out there only turn off the heating element and not the fan, hence it runs ALL the time! Fine I suppose if you do not pay for your electricity. So far this fan has behaved faultlessly and has been a success.

by Rodney Winch

Has not been used yet but the looks and structural build of the heater look top notch. The service and delivery where once more brilliant.

by L M Burger

Have tried it out in the recent cold weather in our 8' x 12' greenhouse and it performed very well in keeping the whole greenhouse frost-free. Lots of adjustment available and will also be useful in keeping the greenhouse cool in the summer.
