Description

Keep Reservoir Temperature Steady Through the Cold Months

The BOYU 100W Nutrient Heater (model HT-8100) is a fully submersible, thermostatically controlled glass heater for warming nutrient solution in hydroponic reservoirs and small tanks. Set the dial and it cycles itself on and off to hold the temperature, so an unheated space overnight does not chill the root zone. It comes on a 1m cable and is a compact, low-cost way to take the chill off a small DWC tote or propagation reservoir.

Key Benefits

  • Built-in thermostat - set once and it holds your target temperature automatically
  • Fully submersible - sits in the solution for even, direct heating
  • 100W output - right for smaller reservoirs and tanks
  • Clear glass body with a visible temperature scale on the adjuster
  • Low running cost - it only draws power while it is heating

Cold Nutrient Solution Slowing Everything Down?

When reservoir temperature drops too far, root activity slows, nutrient uptake becomes sluggish and plants sit still even under good lighting. Big overnight swings are just as unhelpful. A thermostatic heater holds the solution in a steady range, so the root zone keeps working through cold nights and winter grows.

How to Use

  • Submerge the heater in the reservoir before plugging in, keeping it clear of pots, roots and the tank floor
  • Set the thermostat to your target - most growers aim for around 18-22°C
  • Size it - a common rule is roughly 1W per litre; use a larger heater for big tanks or cold rooms
  • Unplug and let it cool for a few minutes before lifting it out of the water
  • Check the temperature with a separate thermometer after the first day
