“The inexpensive one”


The KSTW is suitable for use in water with a high chloride content (unlimited). When connected to a central heating system, complete with a welded-in immersion sleeve, it heats the swimming pool water while minimising the tendency for limescale formation. The flow temperature is 90°C. In contrast to the WTI, the KSTW is made of plastic, with the same performance, but a shorter service life.
