The Palram Canopia 2400W Greenhouse Heater delivers 8600 BTU through a low-noise fan, covering greenhouses up to 14 square metres. The separate digital thermostat uses two independent sensors for accurate temperature readings. IPX4 splash resistant and CE certified for greenhouse use.
What sets this heater apart is the external digital thermostat. You mount the thermostat controller away from the heater, closer to your plants, so it reads the actual growing temperature rather than the warm air right next to the fan. Two sensors cross-check each other for accuracy. Set your target and the heater cycles on and off to hold it.
The fan-only mode is worth having through summer. Run it without heat to circulate air and reduce humidity, which cuts down botrytis and mildew problems. The 3-position switch makes it simple: heat, fan, or off.
The heater comes with a 2 metre cable and plugs into a standard 13A socket. Mount it on the floor or on a shelf. The metal cradle frame tilts to direct airflow where you need it. At 2400W it draws about 10p per hour at current electricity rates, so running it overnight through a hard frost costs roughly 80p-£1.

Clear Polycarbonate: This polycarbonate is completely clear like glass. It is very thin at 0.2mm, but extremely tough and shatterproof.
Twin Wall Polycarbonate: This polycarbonate is virtually unbreakable and high impact resistant. They are slightly opaque, preventing strong sunlight exposure, yet offer 80% light transmission with high thermal insulation. The panels are 100% UV protected and will not discolour, fracture or shatter.
Yes it’s shatterproof and high impact resistant. However, as polycarbonate is very light, we do not recommend placing these greenhouses in exposed areas with high wind.
No, there is no floor or base. These greenhouses are ideally to be placed on a concrete, slab or decking base.
We recommend securing the greenhouse to a hard, level surface (concrete, slabs, or decking) immediately after construction. This is essential for the stability and rigidity of your new greenhouse. You can use a screw and a washer through the compatible pre-drilled holes in the greenhouse frame into a raw plug in your concrete/slab surface.

A solid base is the backbone of any greenhouse. You might think skipping this step saves time, but trust me?I've seen plenty of greenhouses fail because of poor foundations. A dodgy base causes more headaches than you'd believe.
What happens with a bad base? Glass cracks. Doors jam. The structure twists. Water pools where it shouldn't. And fixing these problems costs way more than doing it right first time.

Placing your greenhouse in the right spot makes all the difference between thriving plants and disappointing results. As a greenhouse specialist who's spent 15 years helping UK gardeners optimise their growing spaces, I've seen first-hand how position affects everything from temperature regulation to plant health.
Let me share what actually works in our unique British climate. The greenhouse position might seem like a minor detail, but it's one of those things that can make or break your growing success. I made this mistake myself when I first started - my poorly positioned greenhouse meant I was fighting an uphill battle with inadequate light and temperature fluctuations.
