Large ball valve handles
easy handling, visible closing position

Thermal control valve (adjustable) prevents the flow temperature from rising above the set maximum temperature.The control valve also enables to adjust the maximum temperature appropriately to the installation (40 - 50 °C).

Bypass (adjustable on the front) increases the circulating water quantity and decreases the flow temperature when open.

Thermostat, adjustable in the range of 20 - 60 °C, when the adjusted temperature is exceeded a switch is activated and shuts off the pump.

EnEV-compliant functional insulation
made of durable elastic EPP, complete insulation of valves and fittings, ventilation opening to cool the pump

Free access to the pump head
by simply removing the front insulation shell

Check valve in the return pipe
can be opened, 200 mm wc, spring-loaded, thus suited for horizontal and overhead installation

Flow on the right = standard
Flow and return line can be changed on site, also for heating circuits with mixing valve

All water-carrying parts are made of brass

Full metal thermometers
can be pulled off, with immersion sleeve integrated in the ball valve

PAW heating pumps with high-efficiency (ECM) technology
fitted with 2 m cable, completely premounted, integrated in the insulation, pressure tested, with serial number, perfectly designed system, pump characteristics, EuP/ErP READY

Pump can be isolated,
so that it can be replaced without draining
