Grundfos 00595444 Aquastat
The Grundfos 00595444 Aquastat is a professional-grade thermostatic control kit designed specifically for integration with Grundfos UP Series circulators. This 3/4 inch clip-on aquastat is engineered to optimize hot water recirculation systems by managing pump cycles based on real-time line temperatures. The surface-mount sensor features a bi-metallic disc that triggers the circulator to engage at 85°F and cycle off once the temperature reaches 105°F. This precise thermal management prevents continuous pump operation, significantly reducing energy consumption and mechanical wear on the circulator pump. The unit includes a PVC jacketed cable with shielded wire for reliable signal transmission in demanding mechanical room environments. Designed for 7/8" OD piping (3/4" ID copper or 1/2" steel), the Grundfos 595444 provides a secure, snap-acting connection that ensures consistent thermal contact without requiring system drainage for installation.
Key Benefits- Optimized Efficiency: Eliminates 24/7 pump operation by cycling the Grundfos UP Series only when water temperature drops below 85°F.
- Broad Compatibility: Engineered for seamless integration with single-speed 115V and 230V recirculating pumps.
- Durable Construction: Features an environmentally sealed enclosure and PVC jacketed cable to withstand typical HVAC humidity and heat.
- Easy Installation: The 3/4" clip-on mount allows for rapid retrofitting onto existing 7/8" OD copper tubing without pipe cutting.
- Reliable Switching: Rated for up to 10A at 120VAC, providing a robust electrical interface for standard domestic hot water applications.
Does this aquastat work with multi-speed pumps?
While designed for Grundfos UP Series single-speed circulators, it can be wired into the control circuit of many hot water recirculation systems; however, verify that the amperage draw of your specific motor does not exceed the 10A resistive rating.
Where should the sensor be mounted for the best results?
For peak performance in a recirculation loop, mount the clip-on thermostatic control on the return line near the water heater to ensure the pump only runs when the loop has actually cooled. Ensure the copper pipe is clean of debris to maintain accurate thermal transfer.
Can I use this alongside a timer?
Yes. In high-efficiency setups, contractors often wire the 595444 Aquastat in series with a mechanical timer. This configuration ensures the pump only activates when both the time window is active AND the water temperature has fallen below the 85°F setpoint.
