Lighthouse Ecoheat Thermostatic Tube Heater for Grow Rooms

Hold a steady grow room temperature without babysitting a thermostat

The Ecoheat thermostatic tube heater is a low-output tubular heater built for greenhouses, grow rooms, sheds and garages where a few degrees decide whether growth carries on or stalls. A digital thermostat shows both the current room temperature and your target, giving accurate control up to 25°C. Four sizes cover different spaces: 45W at 305mm, 80W at 608mm, 135W at 915mm and 240W at 1220mm. Three programmable modes - Timer, Delay and Cycle - run on 1 to 24 hour settings, so heat arrives when the room actually needs it rather than running flat out all night.

Key Benefits

• Readable digital control - the display shows room temperature alongside your set point, so you can see at a glance whether the heater is keeping up.
• Three scheduling modes - Timer, Delay and Cycle over 1 to 24 hours let you match heating to your lights-off period instead of heating around the clock.
• Automatic safety shut-off - if room temperature falls by 10°C within 10 minutes the heater powers down and restarts once conditions settle.
• Four wattages - pick 45W for a propagation cupboard or 240W for a larger insulated room, so you are not paying for output you cannot use.
• Gentle tubular heat - a long, low-temperature element spreads warmth along its length rather than blasting a single spot of foliage.
• Plug in and go - no wiring, no separate controller, just set the mode and target temperature.

Why Night Temperature Drops Undo Your Progress

Most UK grow spaces are warm enough while the lights are on and far too cold once they go off. That swing slows root activity, tightens internodes for the wrong reasons and pushes relative humidity up as the air cools, which is where condensation and mould problems begin. A small tube heater running on a thermostat closes the gap cheaply, keeping the dark period within a few degrees of the day and letting plants carry on working overnight.

How to Use

• Mount the heater low in the room, clear of foliage, pots and water.
• Set your target temperature on the digital thermostat, up to 25°C.
• Choose Timer, Delay or Cycle mode and set the hours to suit your lights-off period.
• Keep at least 30cm between the tube and the nearest plant or tent wall.
• Check the display after the first night and adjust the set point to match your readings.
