Hello, in the interests of energy efficiency I installed a Grundfos UPS3 pump in place of an original first generation UPS. My boiler now says it isn't getting sufficient water flow ...... ???? The UPS3 claims to be a like for like replacement, in fact, it claims a greater head of water specification.
Admittedly I'm using the original body, have just changed the head. Is this where im going wrong? Grundfos claim the head is compatible with the older body, so......?
Any ideas ????
