Reviews about this item

Quick delivery working well

Product : Would have given 5 stars but as it has been only in use for a week I not long enough and not yet cold enough to see how it performs in colder conditions.

Hotbox Regal Silver 4kW Greenhouse Heater


The Regal Silver 4kW greenhouse heater with non-electronic thermostat is available as an LPG or Natural Gas model and will heat an area of up to 140 sq ft and provide frost protection for an area of up to 350sq ft.

The Regal is manufactured in long lasting aluminium coated steel, with a stainless steel burner, affords the gardener the simplicity and reliability he expects and provides a generous heat output of 4kW for almost any size of amateur greenhouse.

Regal Silver has a non-electric thermostat which turns the heater down to just a small pilot flame when desired temperature is achieved.

Natural gas models should only be installed by a Corgi registered gas fitter and propane models require a regulator, available from the options section below.

Also available is a B.S high pressure hose with two jubilee clips, supplied in 1 metre lengths; a gas low gauge, which when attached to a regulator will indicate when you need to replace the gas cylinder, and an auto changeover valve that will automatically switch from one gas cylinder to another (includes hoses, connections and full user instructions). For natural gas models a connection kit is available, screwing into the back of the heater with bayonet connector at other end.

Gas powered greenhouse heaters should only be used in well ventilated areas to ensure the CO2 sensor is not set-off thus cutting out operation.
