FWS 20

Product catalog summary

Overview: The Fresh Water Station FWS20 by Kioto Solar is designed to provide constant fresh and hot water through a combination of the KIOTO fresh water system tank (FWSS) and the fresh water module (FWS). It features a patented temperature control system that ensures no latency or thermal fluctuation.

Advantages:

Space Efficiency: Compact design with minimal external piping as the FWS is directly attached to the FWSS tank.
Hygiene: Heats water on demand, preventing legionella formation through continuous-flow heating.
Comfort: Easy plug-in installation, maintenance-free, constant hot water temperatures, self-deaeration, and wall mounting capability.

Technical Specifications:

Suitable for 1-2 families.
Heat insulated model with separable flat sealing system connections.
High output due to large heat exchangers and fast reaction time.
No temperature relief valve needed, reducing water and energy losses.
Pre-adjustable hot water temperature with simple fixation.

Functionality: The FWS operates on a continuous-flow heating principle, ensuring fresh hot water with low standby losses. The charge pump circulates heating circuit water through a two-pass heat exchanger, with temperature adjustments made by a patented control unit.

Components:

Check valve
Heat exchanger
Charge pump
Push-in connection for circulation unit
Optional circulation unit with pump and electronic return thermostat
