PAW Hydronic Heating Pump Station K31-1"
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.
Pump Station
The complete integrated pump station saves time on installation, allows for pump servicing and seamlessly integrates with the PAW Distribution Manifold for parallel installation of multiple heating circuits. 1” FPT allows you to attach to PEX or Copper pipe or use our Aurora Flex stainless steel piping for solder free connections. Accurate thermostats and brass ball valves add to the features of these pump stations.
PAW pump stations come in a variety of sizes and can accommodate systems sizing up to 34 Kw. The Grundfos variable speed pump is available in different sizes to match the flow requirements for each zone. By adding multiple pump stations in parallel to the Modular Distribution Manual you can easily achieve a complete home heating solution for every zone requirement.
Features:
- Full port ball valves for isolating the system
- ¾”-1 ¼” compression fittings
- Fully insulated housing made of EPP elastic foam
- 100% insulation of fitting while allow air for pump to cool
- Flow check valve in return pipe prevents anti siphoning when pump is off
- Right or left supply are interchangeable to suit existing design
- 100% brass components except for pump
- Integrate accurate temperature gauges
- Pump isolation allows pump to be changed without draining system

Modular Distribution Manifold
The system relies on Modular Distribution Manifolds that allows pump stations to be hooked up in parallel to share a common heating supply’s such as a boiler, solar thermal or a heat pump. These manifolds come in 2,3,4,5 loop configurations and can be expanded past that. There manifolds share the supply and return manifolds from the heating sources on the bottom.
Features:
Heating Distribution Manifold for outputs up to 80 Kw per boiler connection
- Completely made of brass
- Completely pre-assembled
- Completely insulated with high temp EPP foam
- Extremely low resistance free flow
- Up to 5 pre-assembled manifolds modules available
- Multiple connection of heat sources such as gas boiler or wood fired boiler and Heat Pumps
- Comes with wall bracket

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 Hydronic radiant floor heat you should use the K32 Model with electronic mixing valve.
Features:
- 1” NPT female connections
- Large ball valves handles
- Fully insulated enclosure using EPP
- Check Valve built into the return piping
- Reversible supply and return on right or left side (field changeable)
- All brass construction
- Metal temperature gauges
- Pump isolation for quick system repair
- Includes Grundfos ALPHA 25-55 U

Return Policy
We want you to be 100% satisfied with your purchase, if you are not, ship it back to us in the original packaging condition and we will refund your purchase less a 10% restocking fee, provided the equipment is received in good condition. Refund offer valid for 30 days from receipt of product.
Warranty
We feel that being honest is a much better policy to win your trust rather than trying to lure you with nearly impossible statements such as lifetime warranty. Nothing lasts forever! Our warranty policy is simple; we offer a 3 year warranty on everything we sell and 10 years on our collectors. With this warranty you will get NO hassle next business day replacement (if shipping service and inventory permits). However, as a valued customer you will get technical support through the lifetime ownership of your product. Our Collectors do carry longer warranties 10 years from the manufacture. The warranty cover failures that occur during normal operational conditions or manufactures defects. It does not cover failure due to inappropriate operation such as freezing or over heat. Damage caused by vandalism, storms, floods etc. Your houshold insurance should be modified to cover the system from such situations.
We accept PayPal and Credit card (Visa or Mastercard). If you are ordering multiple units and part, please call us to see if we can save you shipping cost for multiple item orders.
For complete solar kits please allow 2-3 weeks delivery. These kits are shipped via our preferred freight forwarder company and where possible we will schedule residential tailgate delivery (curbside). Heaters and accessories are usually in stock unless indicated otherwise. We do have expedited shipping services available for an additional fee. Please call us if you need a rush order. Once your order has been shipped you will be contacted via email and a tracking number will be provided.
