ACT E10 lead-free pump was designed with high efficient electronically commutated permanent magnet motor (ECM/PM technology) specifically for potable water systems. This unique design is perfect for retrofits, no recirculation pipe required, and systems with tankless water heaters. GPM given is max.

Timer: This system has a timer which means that you can set it to turn on for just the hours you’re home. For example, instead of leaving it running 24 hours a day, you may want to have it turn on the hour before you wake up and a few hours around the time you get home. That way you’ll get hot water to wash you face and hands and in the shower. Also features a fixed thermostat.
Quality: I couldn’t find the warranty information, but it’s probably 1 or 2 years just like the other Liang products. Amazon also offers 1 and 2 year additional warranties.
Price: View current price on Amazon. This might seem expensive, but you can’t compare it to the other products prices because this is for tankless water heater applications.
Installation: 1 Hour installation at most. Very simple project that even beginner DIYers will have no problem with. This is a Water Heater Installed Recirculator (which you can read more about Here) meaning that the main pump needs to be installed at the water heater and the valve needs to be installed below the faucet of the sink furthest away from the heater.
