Tomorrow I’m being sent to flush a 20+ year old hydronic heating system. Being in the south east and primarily residential, I’ve only even seen 3 boilers ever. This is the first hydronic heating coil and radiant floor heating I’ve ever seen in 20 years. What I know There’s a boiler, hot water tank, two zones are radiant floor, and one zone goes to a hydronic heating coil attached to an air handler. Can anyone point me in the direction to some resources on flushing these?
