Greenhouse Heater — Electric Fan Heating for Year-Round Growing Control
Best for: Growers extending their season, protecting seedlings from frost, and maintaining stable temperatures in unheated greenhouses
Our thoughts
A proper greenhouse heater is the difference between growing twelve months a year and being locked out by winter cold. This one gives you thermostat-controlled heat that actually works — no cold spots, no guessing. One we recommend a lot for growers who want to protect their crop without overcomplicating things.
A greenhouse heater is your answer to maintaining consistent growing temperatures when the cold months arrive. Plants thrive between 18–25°C, and anything colder than that and growth slows, results suffer, and frost damage becomes a real risk. This electric fan heater works by circulating warm air evenly across your entire growing space, eliminating cold pockets, reducing condensation, and keeping humidity stable. Thermostat-controlled, it switches on and off automatically — you set the target temperature and let it do the work. End-of-line stock, so you're getting proper heating kit at a much lower price than usual.
How it compares
Electric fan heaters sit in the entry-to-mid tier of greenhouse heating options.
-
Fan heaters (like this): Fast warm-up, even air circulation, works brilliantly with thermostats. Best for small to medium greenhouses.
-
Infrared heaters: Direct radiant warmth, more energy-efficient, silent operation. Pricier upfront.
-
Tube heaters: Ultra-low power consumption (45–135W), compact, budget-friendly. Best for supplemental heat or tiny spaces.
-
Gas/propane heaters: Only for commercial-scale operations. Overkill for hobby growers.
This fan heater strikes the balance between heating speed, air circulation, and cost.
Usage guidance
Installation
Plug the thermostat into a wall outlet first. Plug the heater's power cord into the outlet on the thermostat face. Set your target temperature. That's it.
Spring seedling protection
Light levels are rising but night temperatures still dip below frost. Run the heater on a low setting to keep seedlings above 10°C and they'll push away without cold stress.
Winter growing
Extend your season by heating to 15–18°C at night. Salad leaves, certain herbs, and overwintering perennials will keep producing when an unheated greenhouse would sit dormant.
Thermostat control
The thermostat works by sensing air temperature and switching the heater on and off automatically. Sensor placement matters — mount it at plant height for accurate readings, not near walls or corners where temperatures aren't representative.
Energy efficiency
Run the heater only when needed. A programmable thermostat lets you set different temperatures for day and night, cutting running costs without sacrificing plant health.

Who this is for
- First-time greenhouse owners who need reliable frost protection without the complexity
- Growers extending their season by 4–6 weeks on either end of the year
- Anyone propagating seedlings and wanting to eliminate cold stress
- Hydroponic and propagation tent growers who need damp-environment rated heating
- Budget-conscious growers who want solid performance without premium branding
Best suited to small-to-medium greenhouses and propagation spaces where fan-forced heat works faster than passive systems.
Our take
This is a straightforward, hardworking greenhouse heater that does exactly what it should — maintains stable temperature, circulates air evenly, and switches itself on and off without you having to think about it. The 1500W output is the sweet spot for most hobby greenhouses, and the splash-proof rating means it won't quit when things get humid.
Good time to buy while clearance stock lasts. Proper kit at a lower price, and it'll add months to your growing year.
