This was a call I got to have a look at a Vaillant ecotec plus 630 system boiler in Wickersley, Rotherham, S66. The customer said the hot water was still working fine but the central heating would only work intermittently and that they often struggled to get it to come back on once it went off.
When the customer told me that the hot water was ok but the heating was an issue, I knew immediately that the issue was probably not with the boiler itself. System boilers and Heat-only boilers on a conventional system don’t know if you want hot water or heating.
Honeywell 2 port central heating zone valve
The controls (programmer, valve(s) etc) tell the boiler to come on, from that point the boiler just makes heat which is circulated via the pump and distributed via the valve(s). So if one is working and not the other then usually you can rule the boiler out straight away.
So I replaced the 2 port Honeywell zone valve and serviced the boiler while i was there. I carry various(Honeywell, Drayton) 2 port and 3 port valves as stock items for repairs such as these and I repaired this problem within one visit. I can usually get these first generation boilers up and running with one visit with the boiler spares and generic central heating spares I carry. Any parts fitted come with a 12 month guarantee.
