Central Heating: Service


Ensuring domestic hot water and central heating efficiency without compromising user comfort, maintaining optimal flow temperatures and longevity of system performance.

Central Heating Systems

All new central heating, underfloor heating systems and fully replaced systems in existing buildings, including the heating appliance, emitters and associated pipework should be sized to allow the space heating system to operate effectively and in a manner that meets the heating needs of the dwelling at a maximum flow temperature of 55 degrees C or lower. These low flow temperature systems 35 - 55 degrees C have been introduced by Building Regulations approved document Part L on 15 June 2022. 

A vast majority of properties in the UK require under 8kW with the most popular size ASHP being installed at 6kW. Accurate heat-loss calculations must be undertaken before any design can take place insuring the ideal heat generator to be installed is of the correct size. Once this information has been obtained the design of the heating system can be carried out taking into account zoning for total floor areas exceeding 150m2 and types of heat distribution specified for the property.


Central Heating Controls

Choosing the right controls for your new central heating system is crucial for insuring the most efficient performance of the gas boiler and comfort levels for the home. Not all controls work effectively with all heat generators. Obtaining the right temperature for the emitters is key to creating the perfect balance within the system of efficiency without compromising on comfort. Weather compensation and load compensation controls interact intelligently with the boiler, reducing the flow temperature according to the sensor's input. These are controls that will adjust accordingly throughout the day aiming to keep the set point within the property, a must for our British weather.

Priority Domestic Hot Water

Central heating systems comprising of a gas condensing boiler and hot water cylinder using a standard S-plan or Y-plan configuration are set to at one flow temperature which will be the temperature for the cylinder at around 65°C - 75°C operating with a combined heat output for the hot water and heating demand. Running at these high flow temperatures limits the potential for the boiler to condense effectively, for most of its lifespan, find out more information on priority domestic hot water.

Pressure Independent Thermostatic Valves

Dynamic TRV or Pressure Independent Valves (PIV) radiator valves are designed with a flow limiting device for presetting of the maximum water flow through a radiator. The built-in pressure regulator keeps the differential pressure over the valve at a constant level so regardless of other radiators closing in the system the flow will not exceed.


The extra flow from the circulator cannot leave the boiler forcing the boiler to react immediately and modulate down. These valves also keep the differential temperature across the system creating lower return temperatures, improving condensing conditions and overall efficiency.

Power Flushing Services

Power flushing is a technique used to clear sludge, rust, and other debris in the central heating system pipes, radiators, coils, and heat exchangers. Allowing the boiler and central heating system work more efficiently as circulation is improved through the pipework and boiler

Power flushing cleans the inside surfaces of your central heating system. The procedure is more effective with chemicals and magnets read more

Boiler Servicing & Repairs


It is recommended that a ‘Gas Safe registered engineer service your boiler once a year, it is a legal requirement for all landlords to have a gas safety check every 12 months.
