with 1" union nut for assembly on PAW distribution manifolds
with PAW mounting equipment, the HeatBloCs can be installed on wall brackets
Large ball valve handles,
easy handling, visible closing position
EnEV-compliant functional insulation
made of durable elastic EPP, complete insulation of valves and fittings, ventilation opening to cool the pump
the insulation for the distribution manifold is integrated in the heating circuit insulation
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
