Hotbox Natural Gas Heater

Heaters Include push button, piezo ignition for easy lighting.

Automatic flame failure device.

Thermostatic control – with temperature range of 6-38ºC (42-100ºF)

A sensor on a flexible lead lets you position it in the most temperature critical part of your greenhouse, away from cold draughts or direct sunlight. You can leave the sensor on the side of the heater or it can be moved up to 2ft (61cm) away from the heater.

The thermostat will operate in three steps:
When the thermostat sensor is satisfied that the temperature has been achieved the heater will burn on pilot jet only.
When the temperature falls to the thermostat setting – the main burner will burn on minimum setting giving approximately 50% full output, to maintain the selected temperature.
If the temperature falls below the thermostat setting – the main burner will burn on maximum, giving full output to raise the temperature.

Heater size approximately 14 inches wide x 21 inches high x 7 inches deep (36cm x 53cm x 18cm).

Ideally position the heater in your greenhouse so that it gives good air circulation – across the greenhouse will produce the best results. On a slope, install the heater at the lower end, the cold air will want to fall to the lower end and allow the warm air to rise. The heater should be positioned a minimum of 6 inches (15cm) from glass or wall of your greenhouse or combustible material.

Available in two models:

2.5KW model – suitable for greenhouses up to 10ft x 12ft
4KW model – suitable for greenhouses up to 10ft x 20ft.

Please Note:
Any natural gas heater should be installed by a professional fitter, preferably ‘Corgi’ registered.
No connection fittings are supplied, the engineer will supply these as part of the installation.
As these heaters are not flued outside they are only recommended for use in well ventilated greenhouses.
