Hi, I am in the process of replacing a FHP GT042 (installed in 2000) with a Waterfurnace NSV042. My original flow center (non pressurized/dual motor) seems to be working fine with the exception of some rust around motor flanges from condensation. Driller who did my ground loop advised WF contractor that due to the age of the flow center (18 years) they'd suggest replacing it too. Curious as to your opinion on that...probably another $1,5-$2k additional cost. My thought is there's not much that can fo wrong with it other than a pump or seal/gasket failure and really no reason to replace until it breaks.
Hi and welcome! If your installer can do a flow center repair or replace when needed, I would let it ride till it is broke. Eric
Thanks. I got a prelim quote for just under $1500 to get installed same time as the WF unit. I'm sure it would be $300-$400 more down the road (extra trip etc.) but I think I'm willing to roll the dice.
