Grow Gadgets 2000w Oil Filled Radiator 220-240v - Background Heat for Larger Grow Spaces
Best for: growers with a larger room or multiple tents who need dependable dark-cycle heat without the drying effect of a fan heater.
Our thoughts
Fan heaters are quick but harsh on humidity, and in a bigger space that swing is more noticeable, not less. This radiator's two power settings mean you're not stuck running full whack all night when a lower setting would hold your target fine. Steady, unglamorous heat that does the job without messing with your air.
The Grow Gadgets 2000w Oil Filled Radiator is a larger sibling to the 1000W model, built for bigger rooms or multiple tents where more heating capacity is needed. It heats internally-held oil that radiates warmth evenly out into the room rather than blasting hot air the way a fan heater does, with an adjustable thermostat to hold a set temperature and overheat protection for safe unattended running. It also has two power settings - 800W and 2000W - plus castor wheels for moving it between rooms and built-in cord storage.
As with the smaller model, this is aimed squarely at the dark cycle problem: once your grow light switches off, background heat drops with it, and that's when temperatures can crash hardest, especially through winter. Because it heats gently via oil rather than drying the air with a fan, it's a better match for a grow room where humidity control matters as much as temperature.
How it compares
The main comparison points are against the smaller radiator in the same range and against fan heaters generally.
- The Grow Gadgets 1000w Oil Filled Radiator covers smaller spaces (up to roughly 3m x 3m); the 2000W model steps up to around 4m x 4m of coverage.
- Fan heaters heat faster but dry the air more aggressively and add fan noise running through the night.
- Household oil-filled radiators will heat a similarly sized room but generally lack the multiple power settings and grow-room-oriented thermostat range this model offers.
For larger grow spaces needing consistent, humidity-friendly heat, this is the sensible step up from the 1000W model.
Usage guidance
Setup and day-to-day use follow the same principle as the smaller model, scaled up.
Choosing a power setting
Use the 800W setting for milder conditions or smaller spaces within your room, and switch to 2000W for colder nights or larger areas.
Setting the thermostat
Adjust the built-in thermostat to your target temperature rather than leaving the unit running flat-out continuously.
Moving the unit
The castor wheels make it easy to reposition between tents or rooms as needed, and the cord storage keeps the flex tidy when not in use.
Coverage
Rated for spaces up to around 4m x 4m - for anything larger, additional heating or multiple units may be needed.

Who this is for
- Growers with a larger room or multiple tents needing more heating capacity than the 1000W model provides
- Anyone wanting to avoid the humidity swings that come with fan heaters
- Growers who need to move a heater between spaces regularly
- Budget buyers wanting straightforward, dependable dark-cycle heat
Suited to rooms up to around 4m x 4m - the 1000W model is the better fit for smaller tents.
Our take
The two power settings are the standout practical feature here - you're not forced to run full 2000W output when a lower setting would hold your target temperature just fine, which matters for running costs over a full winter. Solid, dependable heat for a bigger grow space.
Delivers reliable performance for larger setups. Worth picking up if you want dependable background heat that doesn't fight your humidity control.
