Takes over 60 seconds to get hot water at my kitchen sink, so I need to hook up my recirc pump myself since my plumber flaked out on me. I have a old home with all new supply piping including a 1/2 recirc line. Water heater is an instant hot Takagi TKD-20 that requires 3/4 Gallons per minute demand in order to fire. Water heater is located in the basement, recirc line is from upstairs bathrooms on 2nd floor. Total rise from heater to top of recirc riser is about 12'. Plumber planned recirc pump to be located in utility room in basement. Looked at the Grundfos Model UP10-16B5 ATLC. My preference is to locate the pump in the basement utility room. Will this pump work? Will it created 3/4 GPM demand even with a 12' rise from the heater to the end of the recirc run? Takagi manual can be viewed at:
