The PAW HeatBloC®s are premounted groups of fittings for heating circuits in the nominal diameters DN 20 to DN 50.PAW offers a broad range of heating circuits - from direct HeatBloC®s to mixed HeatBloC®s with 3- or 4-way mixing valve or thermal control valve to mixing valves with bypass or 3-temperature mixing valves. Modular distribution manifolds and special purpose solutions as boiler connections and return flow temperature maintenance complete our range of products.All HeatBloC®s are designed such that they can be directly mounted onto a distribution manifold or a mounting plate with thread connections. With transition connections, the HeatBloC®s can also be mounted on modular distribution manifolds of other dimensions.The single modules can thus be combined without any problems and can be arranged in numerous ways. This extraordinary flexibility is achieved by the modular structure of the entire system. It allows you to plan, install and extend distribution manifolds rapidly and professionally.HeatBloC® is a registered trademark in Germany.

All HeatBloC®s offer the following advantages:Full port ball valve, gaskets of the spindle can be replaced during operationFlat-sealing connections DN 20 to DN 32including union nut for assembly on a PAW distribution manifold

Flange connection DN 40/50including gaskets and screws

The HeatBloC® can be installed on a wall bracketLarge ball valve handles,easy handling, visible closing position

EnEV-compliant functional insulationmade of permanently elastic EPP, complete insulation of the valves and fittings with sealing lips, ventilation opening to cool the pump

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

PAW mixing valve with suitable actuatoreasy assembly and disassembly thanks to the smart PAW snap-in mechanism

Flow on the right = standardThe HeatBloC®s can be delivered with flow on the left against additional charge.

Flow and return line can be changed on sitealso for heating circuits with mixing valve

All water-carrying parts are made of brassFull metal thermometercan be pulled off, with immersion sleeve, integrated in the ball valve

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

Free access to the pump head, pump can be isolatedso that it can be replaced without draining
