Customer Reviews

Excellent product

I have been putting in hot water recirc pumps for over 15 years and have not seen a better pump for the job. Having the timer and aquastat built in is such a time saver and it gives the end user control of the unit.

Questions & Answers

Does it work with tankless water heater.

by Richard D. from Sherman Oaks on 05-18-2012

I recommend contacting the manufacturer of your tankless water heater to check if it can be used used with a circulator pump. While this pumps may function with your tankless heater, it may shorten the heater's life and in some cases void the manufacturer's warranty. Some manufacturers also recommend only using specific models of recirculator pumps due to specific features they provide.

by Richard D. from Sherman Oaks, CA on 05-17-2012

This pumps should be mounted near the output line of your water heater. Please follow this link for more information (Click Here to View PDF).
