I have an Ideal Classic RS260 wall hung boiler, a Honeywell ST6400 Programmer, a Honeywell Room Thermostat, a Grundfoss 15/60 Circulating Pump and a V4073A Mid-Position Diverter Valve in a 'Y' Plan.
I hope that makes sense!
My problem is this: I have plenty of hot water both upstairs and downstairs but no central heating. The programmer appears to be working (i.e. comes on at the right times) and when I turn up my thermostat I hear a click which would then start my central heating but doesn't. If I feel my pump it is hot, as are the pipes either side of the pump.
The house and system are only just 3 years old. Is it my pump which is faulty? If so, is it easy to change or do I need a plumber?
Any advice would be gratefully received.
