Main highlights

Versatility: With the user-friendly temperature control knob, the water temperature can be easily adjusted and maintained between 0-45°C. The thermostat turns on or off automatically depending on the set temperature. When the temperature exceeds 60ºC, the reset button pops up and interrupts the power supply, so a manual reset is required to resume operation. Overheating limit: 60°
TESTED: The instantaneous water heater for whirlpool or swimming pool is tested according to TÜV and CE standards and carries the corresponding certification. The whirlpool heater is used in hot water circulation systems to heat and maintain water temperature and is good for bathtubs and swimming pools
Reliability: This 2.0 kW hot tub water heater made of high-quality materials is very robust and durable. The inner tank of the thermostat is made of stainless steel, has a long service life and remains rust-proof for a long time. The electric heater thermostat has a high efficiency, is very practical and easy to use. VAC - 230 V no plug
High Efficiency: the hot tub heater must be connected to a circulation pump with a capacity of more than 0.25 HP. Smaller pumps may not provide enough water flow to activate the heater. In addition, the whirlpool thermostat must be connected to a circulation pump and not to a booster pump or submersible pump
Function: Place the hot tub radiator horizontally and make sure the water flow direction matches the arrow on the device. To speed up the heating process, fill the tub with hot water and use an insulating cover (outdoor whirlpools) to retain heat and ensure faster and more energy-efficient operation. Suitable for baths and spas and small pools up to 750 litres
