Services on Heating


Radiator valve replacement

When radiator valves start to leak, obviously is time to replace them. The system needs to be drained to allow working on radiators and replace the components.Final part is to bleed the system which will prevent unpleasant noises.Thermostatic head valves installed will help adjust and manage each radiator temperature for a correct heat output when needed

Time required on average 1 hr work. Minimum visit charge applied plus parts required to finish the job.


Unvented hot water cylinder installation/Servicing

Hot water unvented cylinders need servicing Once a Year to keep them safe to use. During service visits we will control the installation of mandatory components for installation and check all security devices which protects the cylinder from overpressure due to thermal expansion of water. A regular service would prevent hot water pressure loss issues and good health of the component.

Installation of a new Hot water cylinder or upgrade is needed and avoids future breakdowns for a hassle free life. All new or replacement of hot water cylinders involves plumbing and electrical connections to existing pipework and floor reinforcing to support the weight.


Central Heating components replacement

Central heating pumps: A key component of the heating system responsible for circulating water in the heating system. Failed pump will stop your boiler with obvious consequences. When it comes to replacing the pump, an investigation of water quality is needed to establish the cause and not only replace the component but also ensure all other parts are protected. Power Flush of the heating system is advisable.


Zone valves

A very common cause of central heating failure. No matter what the reason, when the valve isn't working correctly you will have unsatisfactory performance.


  • No Heating or hot water only
  • Boiler or pump always on
  • Pipework loud noises



The water in the heating system can be considered as a closed circle. The same water circulates through the boiler and all Central Heating components. Heated water heats up the radiators and /or Hot Water cylinder pushed by the circulating pump transferring heat to the house. Constant thermal actions over the years cause the water to become acidic which will corrode all metal components producing metal particles( Magnetite), sludge damaging Boiler heat exchanger, Central heating pump, all valves and radiators. With the help of powerful magnets in combination with proper chemicals, a correct PH and water quality can be achieved. This procedure is noisy, takes at least a full day of work. An inspection visit and pretreatment is required to achieve the best results. Up to 10 radiators £450, up to 20 radiators £750.
