Plug and Play Hydronic heating and cooling solutions with PAW Modular Zone Pump Stations.
With German Engineered PAW modular pump stations you can design heating system quickly while delivering the highest performance and quality standards in the industry. The PAW Zone pump module quickly connects to a centralized distribution manifold allowing you to share the heat source to multiple zones. Now you can easily design a complete home hydronic system that can do radiant floor heating, domestic hot water, radiators and fan coils, as well as pools and hot tubs. All with one single boiler connection.
The K31 with 1” NPT connections is used for high heating zones that do not require mixing. This can be most zones such as domestic hot water, fan coil radiations and pools or hot tubs. For Hyronic radiant floor heat you should use the K32 Model with electronic mixing valve.
