Exact Replacement
"My Home is 11 years old, just purchased 1 year ago,discovered my Grundfos Boiler Bypass Pump was seized. Ordered replacement from PEX works great. Was able to leave original sweat connections in tact with old housing. Loosen four bolts 4mm on pump housing and thats it!"

Ask a Question
Is this the best Grundfos Pump for a dedicated Hot Water Recir. Line?
Helpful? Yes 2 No
Grundfos makes a lot of pumps suitable for hot water recirculation. The "best" one is the one which has operating parameters (flow rate and head) that match your system's requirements. UP15-18B5 is a popular model for hot water recirculation applications, but you may also want to check out the Comfort Series circulators - these are specifically designed for hot water recirculation and depending on the model, may come with timer and/or aquastat.
