Select boiler type
This type of system heats hot water as you need it, without the need for a hot water storage tank. So in places where space and hot water requirements are limited, such as flats or smaller houses, these can be very popular systems.
This type of system heats and then stores hot water in a hot water cylinder. So if it is lashings of hot water you are looking for then this could be the system for you.
Select boiler output
The boiler heat output is measured in kW.
24kW and 30kW are popular outputs. The needs of a flat or house with two bedrooms and one bathroom can generally be serviced by 24kW. As the hot water is heated instantaneously, boiler power is primarily determined by the hot water flow requirements.
12kW, 15kW, 18kW, 24kW and 30kW are popular outputs. As hot water is stored in a hot water cylinder ready for use, boiler power is generally determined by the size of home to be heated.

Thermostatic radiator valves
According to Building Regulations Part L1 thermostatic radiator valves (TRVs) should be fitted "on all radiators except in rooms with a room thermostat". For maximum comfort at minimum cost they are a good investment and can be retro-fitted to existing radiators.
TRVs allow different rooms to be heated to different temperatures. Once the desired temperature in a room is achieved the valve closes, allowing more heat to be delivered to other rooms in the house.
Programmer / room thermostat
A new heating programmer & a wireless room thermostat are ideal for added control of your heating system. The programmer controls the time your heating comes on / off. The thermostat switches the boiler off when you desired temperature is reached, helping you reduce energy costs. As the link between the programmer and the thermostat is wireless, there are no cables to run.
Additional or replacement radiators can be added. The price indicated is for a standard 600mm x 1000mm convector radiator. Other sizes will reduce / increase the price. Remember to allow for any additional TRVs.
Over time the heating system builds up sediment which can reduce boiler performance. When installing a replacement boiler it can be a good move to have a powerflush of the radiators, to remove any debris in the system. This is done with a power flushing machine and a suitable flushing agent.
Once the radiator system has been powerflushed then it is refilled with fresh water and a suitable inhibitor.
Region of the country
Installation costs do vary regionally. To get the most accurate estimate to compare with your replacement boiler quote please choose the region you home is situated in.
The installation price assumes a qualified Gas Safe installer who will offer a guarantee on their work.
A magnetic filtration system can make a big difference in keeping your central heating system working in an efficient and economical way.
Iron oxide sludge can build up in your radiators over time, as a result of corrosion within the the radiator. By fitting a magnetic filtration system the magnetic sludge is captured before it has a chance to clog up the boiler. The filter can be cleaned during the annual boiler service.
