Equipment and Explanations

Condensing Boilers

Modern Condensing boilers are highly efficient appliances compared to the more traditional boilers. The efficiency of a typical non-condensing boiler is around 75% compared to condensing boilers that can be over 90%.

Conventional heat-only boilers

Heat-only boilers provide heat for radiators directly, but they need to be connected to a separate hot water storage system to also provide hot water.

Combination boiler

This is the best-selling boiler type for gas central heating in Britain. A combination or combi boiler provides heat for your radiators and domestic hot water on demand.

Heating Controls

Heating controls such as Programmers, Motorised valves, TRV’s, Cylinder and Room thermostats allow you to choose when, where and to what temperature you set your heating and Hot water to. You can choose for your heating and Hot water to come on only when you need it and to heat to your desired.


Programmers allow you to set On and Off time periods for both domestic hot water and heating to suit your lifestyle and improve efficiency.

Room thermostats

Room thermostats simply switch the heating system On and Off when the desired air temperature is achieved. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostats setting, and switching it off once this set temperature has been reached.

Thermostatic Radiator valves

TRV’s sense the air temperature around them and regulate the flow of water passing through the radiator thus allowing you to set individual temperatures within each room.

Power Flushing

Power flushing is used to help restore systems with circulation and boiler noise problems to maximise the systems operation. Power flushing helps remove deposits such as sludge, corrosion debris and sediment and the problems that they cause. Power flushing is also an excellent way to thoroughly clean systems prior to installing new heating appliances.

Fused Spur

A Fused Spur is an electrical isolation switch.  All new boiler installation are required to have a dedicated electrical isolation point adjacent to the appliance.

Earth Bonding

Earth Bonding is used as a means to reduce the chance of you getting an electric shock in the event of a fault.

Main equipotential bonding links water and gas pipes, central heating etc. to the main earthing terminal while Supplementary earth bonding is used in special locations like bathrooms.
