Hot water cylinder servicing in Newcastle

A stored hot water system has more to check than a combi. The cylinder, its safety valves, the expansion vessels, the controls and the pumps all need testing to keep hot water reliable and the system safe.

How we handle hot water cylinder servicing in Newcastle

01

The boiler service included

The visit also covers a full boiler service, so the appliance, the cylinder and the controls are all checked together. That gives a clear picture of how the whole system is performing rather than one part of it.

02

What you get afterwards

We talk you through what we found, note anything that needs attention and agree the cost of any further work before we start. If a part is worn but still serviceable, we will tell you that too.

Hot water side checks

  • Check the pressure in the expansion vessel (3 bar)
  • Test the expansion relief valve on the inlet control set
  • Test the temperature relief valve
  • Clean the mesh filter on the mains inlet set
  • Test the operation of the immersion heater and check the load
  • Check the immersion heater thermostat and water temperature
  • Test the operation of the dual thermostat

Abseloutley class. Came the same day fixed the issue. Not had any problems with my boiler since. Very quick and efficient service.

Masoud has just completed a repair and service of my Vaillant Combi boiler. He managed to fit me into his schedule at relatively short notice. He is an impressive technician; anticipating the source of my problem and having the replacement part to solve it. He completed the service of the boiler efficiently leaving my kitchen as clean as when he entered. I can highly recommend him and will definitely give him a call in the future.

Friendly, reliable and reasonably priced for boiler servicing, also very helpful and quick to come out when we had an issue. Was recommended to us by a friend, and would recommend to others.
