WATER MASTER 200W Heater

200W WATER MASTER irrigation water heater indoor cultivation

The 200W WATER MASTER Heater is designed to keep the nutrient solution within a functional and constant thermal range throughout the day. The recommended working range between 18 ºC and 24 ºC promotes active roots, greater effective oxygenation, and optimal nutrient availability.

The 200 W power provides enough margin to compensate for nighttime drops or drafts in technical rooms, especially in 200–300 L tanks.

The submersible body is installed in a vertical position with suction cups, preferably near a current (inlet or return) to distribute the heat evenly and avoid cold spots.

The adjustable control allows you to easily select the reference temperature and maintain thermal stability even during long campaigns. To prolong the life of the heating element, it is advisable to disconnect 15 minutes before emptying or replacing the solution, respect the minimum immersion level indicated, and let it cool before handling.

Integration with recirculation pumps and air diffusers creates a consistent aqueous environment, with more stable EC/pH and less incidence of cold water stress.

This heater is established as an essential ally among irrigation accessories in RDWC rooms, flood tables, or mixing tanks, providing consistency to irrigation and operational predictability.

Catalog available at Hydroponics Blanes, online grow shop with technical advice, where you can complete the thermal set with opaque lids, thermometers, and controllers.

Indoor cultivation 200W WATER MASTER Heater

In indoor cultivation, water temperature control affects gas exchange, salt solubility, and medium viscosity. With the 200W WATER MASTER Heater the mix is kept within a 18–24 ºC range, avoiding metabolic slowdowns below 18 ºC and maintaining oxygen levels according to the needs of the crop. The result is reflected in more uniform irrigation, roots with better respiration, and a more consistent vegetative and flowering response.

What is the 200W WATER MASTER Heater for?

It is used to warm the nutrient solution in medium tanks, compensate for thermal drops, and maintain stable conditions during mixing, resting, and recirculation. The 200 W power makes it easy to recover the target temperature after refills with cold water, favors predictable EC/pH, and reduces typical winter or fluctuating room incidents.

Irrigation accessories indoor cultivation 200W WATER MASTER Heater

Performance increases when combined with these irrigation accessories within the irrigation system:

• Recirculation pump to distribute heat throughout the tank.
• Opaque lid that limits thermal losses and light entry.
• Digital thermometer or controller with alarm for objective verification.
• Air diffusers to maintain dissolved oxygen levels with warm water.
• Hoses and valves to ensure stable delivery to drippers, rings, or tables.

With this set, the nutrient solution reaches each emitter at a stable temperature, improving irrigation regularity and uniformity among plants.

How to use the 200W WATER MASTER Heater?

1) Attach with suction cups in vertical position, near a current in the tank.
2) Check the minimum immersion level before powering on.
3) Adjust the adjustable control to the desired set-point (e.g., 22–24 ºC) and wait for stabilization.
4) Check with an independent thermometer at several points in the tank to confirm uniformity.
5) Before emptying or changing the solution, disconnect and wait 15 minutes for safe cooling.

This procedure prevents thermal shocks and ensures that the water reaches the irrigation circuit in optimal conditions.
