In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Just wondering what is the average life of a 00VDT circ. I designed and installed a hydronic system a couple years ago, I have a TT PS60 1 zone and 4 loops using a VDT circ. With this cold weather the boiler hasn't shut down, water temp is 160 and thermostat hasn't reached set temp. Anyway was wondering if I should have a spare circ, just in case, haven't had any problems but, was just wondering. Thanks.
