Parts of a heating system that regularly need replacing or repairing include – Central Heating Valves, Radiator valves, Radiators and Circulation Pumps. A heating system can be extended to include new parts of a property, or the whole system may need upgrading; this depends on the capacity of the existing system and the size of the extension required.
If you have a heating problem then an engineer will be able to diagnose the fault and replace the faulty part. Common parts that we replace are the zone valve, 2 port valve, 3 port valve, radiator valve, TRV, or circulating pump. Before adding a new heating circuit the boiler and pump will need to be considered as they may be insufficiently rated/sized.
