What are the Benefits of the Worcester Bosch Condensing Wall Boiler:

+ Cheaper Annual Fuel Bills

+ 5 Year Parts Warranty (when fitted by, and serviced once a year with us)
+ Choose any Gas Fire for the focal point in your living room

solid fuel boiler in a fire place is generally 22,000 BTU’s, a standard gas boiler in a 3 bedroom house is generally 50,000BTU’s which is over twice the power of a solid fuel boiler.
gas boiler also warms up in your home faster than a coal fired back boiler heats up a room..
Condensing Gas boiler with a A” rating is 92% efficient, the efficiency of a coal fired back boiler is guesswork but would be 30% or less.

 What Is a Central Heating PumpWhat is a Central Heating Pump?
A Central Heating Circulation Pump simply moves the hot water from the Boiler around the Radiators and Copper Cylinder , which stores the Hot  Water.
 Central Heating ClockWhat is a Central Heating Programmer?
A Central Heating Programmer works similarly to a Central Heating Clock Timer.
The main difference is that a Heating Programmer allows the heating to be tuned on and off at different times on different days.
 Central Heating ThermostatWhat is a Central Heating Thermostat For?
A Central Heating Boiler Thermostat allows the temperature of the Boiler to be adjusted. 
For Example, durning the Autumn you won't need as much heat produced from the boiler - during the Winter the Heat required will normally be much greater.
The Central Heating Thermostat is normally located on the Boiler.
 Radiator ThermostatWhat is a Radiator Thermostat For?
A Radiator Thermostat allows a Radiator to be adjusted to suit the temperature of the room.
 Room ThermostatWhat is a Central Heating Room Thermostat?
A Central Heating Room Thermostat allows control of boiler in response to the room temperature where it is fitted.

 Gas Boiler FlueWhat is a Gas Boiler Flue?
A Gas Boiler Flue is where the Boiler releases it's exhaust, and draws in air for combustion in the case of Modern Gas Boilers.
On Most Wall Mounted Gas Boilers the flue simply comes off the top, and turns through an outside wall.
 Baxi Back BoilerWhat is a Gas Boiler with Back Boiler?
A Gas Boiler with Back Boiler allows you to conceal the Boiler behind a Fire front.
These Boilers need a Conventional Brick built Chimney to allow them to be fitted.
 Gas Meter BoxWhat is a Gas Meter?
A Gas Meter is normally sited at the Front or Side of a House.
The Gas Meter Measures the amount of gas being used in the house.
Meter readings are normally taken to check the useage against Gas Bills
 Central Heating RadiatorHow do Radiators Work?
A Radiator Works by Convection Heating. The Larger the Radiator that more heat you will get from it.
Older Radiators, particularly single panel types, aren't very effecient. The Modern Double Panel Radiators with Convectors between the panels are the most effcient choice.
These are available on our Website here.
 Central Heating Expansion VesselWhat is an Expansion Vessel?
And Expansion Vessel is a small, normally red, circular Steel tank that allows for expansion of the water in a Central Heating System as it heats up.
 Heating Cylinder JacketWhat is a Cylinder Jacket?
A Cylinder jacket, also known as a lagging jacket, keeps heat in the Copper Cylinder for Longer by insulating sides and top.
Most Modern Copper Cylinders are now already Insulated before being fitted and no longer require a lagging Jacket. 
If you are thinkg of updating your old Copper Cylinder, see here for a full list of prices and sizes of the Ready Insulated Copper Cylinders.
 PowerFlushing FilterWhat is a Central Heating System Power Flush?
A Central Heating Power Flush involves pumping (at higher than normal pressure) water & cleaning products around an existing central heating system.
This can improve the performance of the radiators, and the Central Heating System in general.
Alternatively, you can now use a magnetic cleaning system, known as 'Magnaclean', to clean the system.
This 'Magnaclean' method is much easier on the heating system as they use less chemicals, and the are available to buy here.

Our BOSCH replacement GAS boiler can be fitted in place of Baxi, Vokera, Gloworm , Ideal Classic, Lamborghini, Valiant, Potterton, Myson, Mexico, Profile, Baxi Bermuda, Atmos, Halstead, Potterton Netaheat, Ferolia, Elan, Myson Housewarmer, Apollo, Grant, Halstead Best and Sime.

Wall Boilers are now smaller than ever taking up only a fraction of the space used by older boilers and are usually installed in the kitchen, utility room or garage. They are also pollution free, and quieter and safer then ever with no smell.When a new boiler is installed we add to your system a chemical inhibitor which helps stop and prevent internal corrosion in all boilers and heating systems.
