Review on ๐Ÿ”ฅ BOKYWOX 120W Hot Water Circulation Pump 3/4'' 110V for Solar Heater System - Stainless Steel Red by Tony Jockheck

Revainrating 5 out of 5

Use as the main circulation pump for underfloor heating.

First view when the system just started up 15m ago. The pump expresses 1.7 gallons per minute though my Takagi water heater. Pumps 110F of water into the system, the pump reads 125F so 15F warmer than the system, hope it's ok, asked a question on the product page. I bought some PEX swivel fittings for the installation and used a 3/4" pipe stand to wall mount the pump for now. It's a bit noisy now but I'm just trying to get the system working, the oven is hot and will worry about the noise later. Hopefully this pump can withstand 5 or more hours of initial use to bring this plate up to temperature and will come back to upgrade if it doesn't work in the first tests or if the pump hasn't been in service for at least 3 years. Have a switch box on the wall that turns on the pump when the thermostat calls for heat without cooking or placing the sensor on the stove so the ambient air temperature in the room drops. 2 run in concrete, 1 runs under the old wooden floor of the main building, hopefully not a problem as it is primary heating with no backup source other than an LP oven and dryer which I could run if needed. Overall the pump works as advertised, bought an SS pump to minimize the effects of rust on the bladder tank. New to this hydraulic heater, fingers crossed. 5 stars for now.
