The Right Tools for the Job.

Want to save time? - Solarnetix's own Solarcheck Toolkit will ensure you have the right tools for the job - every time. Use with our Handheld Refractometer to ensure you are prepared for any testing or maintenance situation.

The ZUWA UNISTAR Drill Pump allows you to flush, vent and fill heat transfer fluid - in just one pass. Need more Glycol? Then check out our high quality ProSol L-HT Glycol, available in 5 gallon pails and 50 gallon drums.


RESOL Solar Controller is based on ΔT differential logic  with considering solar thermal system features, such as drainback, anti-frost, collector warming up, flow monitoring, irradiation threshold, high/low limitation of collectors or loads and priority loading and so on. With the typical and special solar functions built in the controllers, the controllers “command” the solar thermal systems intelligently. A ΔT differential logic could be easily found in many controllers in the market; however, the built-in solar functions root from the manufacturers’ dedicated design and long-term experience in the solar thermal industry.

Solar Thermal Plug & Play - A Quick Install Every Time.

PAW Solar Heating pump modules and heat transfer systems are designed for use in closed loop Solar Thermal systems working with glycol.  A modular system design ensures a quick setup and compatibility.

Features of Every Solar Station:

• All water-carrying parts are made of brass

• Sealing Components are resistant up to 266 °F / 130 °C

• Flowmeters are adjustable to set the correct flow rate.

• All pumps are UL-certified and equipped with 3-speed motors.

• Check valves integrated in every line in the solar loop.

• Air scoops in the supply line for easy de-airation



As most of our clients know that we offer installer price for each item, while the prices of on-sale prodcuts are lower than average installer prices. Only do clearance products have their current prices shown. If you are interested in other products, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. to get the price quote as well as freight cost. For the on-sale products, we still provide technical support from system pre-evaluation, feasibility analysis. device selection, and installation follow up. 

The warranty period is one year from the date of Invoice or two years from the date of being manufactured, whichever comes first.

Hope you satisfy with the offer!

Do you want to complete more jobs on time and on budget and make your business more effective and efficient?

Benefits of the Modular Hydronic Distribution System ( MHDS): 

-Cutting down installation &internal administration cost;
-Has an excellent professional design guaranteeing high-quality performance, reduces systems’ operating costs – lowers utility bills;
-Reducing effort to source parts from different vendors, the possibility of incorrect parts delivered, & preparation time of technician lead to propose work sequences in the mechanical room.




Our Pre-engineered Modular Hydronic Zone Panel takes only minutes to connect. It includes all the pipings, valves, circulating and control elements to feed both aradiant floor heating zones and conventional high-temperature heating zone. The Modular Hydronic can be used to connect virtually any piping arrangement.

 Zone Pump Modules and Manifolds

Zone Pump Modules have K31, K32, K33, K34 K36E and K38 models. They satisfy your different requests in the projects.

K31-High Temperature Zone Module. 

K32 -Low Temperature Zone Module with 3-way mixing valve driven by floating point actuator. 

K33-Low Temperature Zone Module with thermostatic mixing valve (Incl. 0-50% adjustable bypass valve) . 

K34-Low Temperature Zone Module with 3-way mixing valve driven by floating point actuator (incl. 0-50% adjustable bypass valve).

K36E-Zone Module to compensate temperature differences in boilers.

K38-Low Temperature Zone Module with 4-way mixing valve driven by floating point actuator. 

Manifolds cooperate zone pump modules to distribution heating in mutiple zones in parallel. 

MV2-2 fold manifold, connects up to 3 zone pump modules.

MV3-3 fold manifold, connects up to 5 zone pump modules.

MV4-4 fold manifold, connects up to 7 zone pump modules.

MV5-5 fold manifold, connects up to 9 zone pump modules.

MV6-6 fold manifold, connects up to 11 zone pump modules. 


Used in closed loop design. In conjunction with boilers having high resistance (condensing) or when total flow rate of all parallel running circulators is higher than maximum flow rate of the boiler, the low-loss header provides hydronic separation, decoupling boiler and system circuits from each other. It is recommended to use the low-loss header in applications in which the total system flow rate exceeds the maximum boiler flow rate. PAW strongly recommends the use of a hydronic separator in cases where the system head and flow rate are unknown.

Air vents in hydronic systems remove  air accumulated in heating and cooling systems. This averts air staying in systems damages hydronic devices and improves system performance. Air vents prevent:

- corrosion due to the oxygen;

- pockets of air trapped in the heating emitters;

- cavitation in the circulation pumps;

- noise from air passing through the pipes.
