AQUAKING 500 W Heater

500 W AQUAKING Water Heater for Indoor Growing

The 500 W AQUAKING Heater (model HE-500) is designed to stabilize the nutrient solution in large-capacity tanks, where temperature affects oxygenation, salt solubility, and the metabolic rate of the roots.

The electronic thermostat allows you to select a fine set-point within 22–34 ºC, compensating for nighttime drops, refills with cold water, or drafts in technical rooms.

The 500 W power provides enough thermal margin to quickly bring the volume to the operating range and maintain it throughout the day, reducing the risk of water stress below 18 ºC and preventing oxygen loss that occurs at excessively high temperatures. The body is submersible and allows for vertical or horizontal installation; the suction cups make it easy to firmly anchor to the tank wall.

Compact dimensions (45.5 × 3.2 × 3.4 cm) allow you to place the heating element near a current (inlet or return) for even heat distribution and minimal stratification.

The electronics reduce moving parts exposed to wear, increasing reliability during prolonged campaigns.

Operational recommendation: disconnect 15 min before emptying or changing the solution; respect the minimum immersion level and incorporate recirculation to even out the temperature.

Integrated with return pumps and air diffusers, this heater consolidates a predictable aqueous environment, with stable EC/pH and repeatable irrigation, something critical in RDWC, flood tables, and master mixing tanks.

Indoor Growing 500 W AQUAKING Heater

In indoor growing, keeping water between 18–24 ºC promotes gas exchange, reduces nutrient lockout, and stabilizes water viscosity. The 500 W AQUAKING Heater provides thermal inertia in large tanks (up to 500 L), ensuring the solution is delivered at the right temperature every cycle and a constant root response even with frequent watering.

What is the 500 W AQUAKING Heater for?

It is used to warm the solution in large-volume tanks, recover target temperature after refills, cushion nighttime thermal drops, and keep the tank within the useful range of 22–34 ºC. This improves fertilizer solubility, keeps dissolved oxygen operational, and achieves more predictable EC/pH parameters for watering indoor crops without surprises.

Irrigation accessories for indoor growing 500 W AQUAKING Heater

For superior performance, it is advisable to integrate:

• Recirculation pump to distribute heat throughout the tank volume.
• Opaque lid to limit heat loss and light entry (fewer algae).
• Digital thermometer or external controller with alarm for continuous verification.
• Air diffusers to maintain dissolved oxygen according to the chosen temperature.
• Hoses and valves of the irrigation system to ensure stable delivery to drippers, rings, and tables.

The sum of these irrigation accessories creates a homogeneous, thermally consistent solution ready to feed all lines with the same quality.

How to use the 500 W AQUAKING Heater?

1) Attach with suction cups vertically or horizontally, preferably near a current in the tank.
2) Check the minimum immersion level before powering the equipment.
3) Set the electronic thermostat to the desired set-point (e.g., 22–24 ºC) and wait for stabilization.
4) Check with an independent thermometer at different points in the tank to confirm thermal uniformity.
5) Before emptying or changing the solution, disconnect and wait 15 min for safe cooling of the heating element.

This protocol prevents thermal shock, protects the heater glass, and ensures water is ready for the circuit at any time of year.
