Grow Gadgets 1000w Oil Filled Radiator 220-240v - Steady Background Heat for Grow Rooms
Best for: growers who need steady, even background heat during the dark cycle without the moisture-drying effect of a fan heater.
Our thoughts
Fan heaters push out heat fast but they also dry the air out and can throw off your humidity readings. An oil-filled radiator heats more gently and evenly, which suits a grow room far better than it suits a spare bedroom. This one's a straightforward, no-nonsense way to stop your dark cycle temperature crashing over winter.
The Grow Gadgets 1000w Oil Filled Radiator (originally sold under the Lighthouse brand name) is a 1000W electric radiator with nine oil-filled fins that heat internally and radiate that heat evenly out into the room, rather than blasting hot air the way a fan heater does. It's built with an adjustable thermostat so you can dial in your target temperature rather than running it flat-out constantly, and it includes overheat protection for safe unattended running.
This matters most during the lights-off period, when your grow light isn't contributing any background heat and room temperature can drop sharply, particularly through winter. Because oil-filled radiators heat gently rather than blasting dry air, they're less likely to crash your humidity the way a fan heater can, which makes them a better fit for a grow room than most household heating.
How it compares
Oil-filled radiators and fan heaters solve the same problem in different ways.
- The larger Grow Gadgets 2000w Oil Filled Radiator covers more floor area for bigger rooms or tents, where 1000W won't be enough.
- Fan heaters heat a space faster but dry the air more aggressively and can be noisier running continuously through the night.
- Generic household oil-filled radiators (De'Longhi and similar) will heat a room but don't come with a thermostat calibrated for the tighter temperature bands growers work to.
For steady, humidity-friendly background heat rather than a fast blast, an oil-filled radiator is the more sensible tool for the job.
Usage guidance
The radiator is designed for simple, low-maintenance operation.
Positioning
Measures roughly 35 x 35 x 15cm - allow clearance around the unit and keep it away from anything that could restrict airflow around the fins.
Setting the thermostat
Adjust the thermostat dial to your target temperature rather than leaving it running on maximum continuously.
Coverage
Rated for spaces up to around 3m x 3m - for larger rooms, consider the 2000W version or additional heating.
Dark cycle use
Run it during lights-off to offset the loss of background heat from your grow light and prevent temperature swings between light and dark periods.

Who this is for
- Growers needing background heat during the dark cycle in a small to medium tent or room
- Anyone concerned about a fan heater drying out their humidity levels
- Growers battling cold garages, outbuildings or spare rooms over winter
- Budget buyers who want a straightforward heater without smart features they won't use
Suited to rooms up to around 3m x 3m - step up to the 2000W version for anything larger.
Our take
An oil-filled radiator isn't glamorous, but it's the right tool for holding a steady temperature through the dark cycle without wrecking your humidity. The built-in thermostat and overheat protection mean you can leave it running unattended with reasonable confidence.
Does exactly what it should, day in, day out. One we sell a lot of for growers heading into winter with a small to medium grow space.
