Boilers
P. Blackhall Ltd are proud to be accredited installers of worcester bosch High Efficency Condensing Boilers.
Worcester Bosch Group has developed a new generation of central heating boilers that not only reduce CO2 emissions, but can also reduce fuel bills. Three quarters of the energy used in the home is for heating and hot water which accounts for about 73% of a home’s CO2 emissions. Boilers over 15 years old are often only around 60 per cent efficient or less (rated G in the SEDBUK* scale), which means that for every pound spent on fuel, 40p is wasted.
WHAT IS A HIGH EFFICENCY CONDENSING BOILER AND WHY IS IT MORE EFFICIENT?
During the operation of a boiler, exhaust gasses are expelled out of the flue; a condensing boiler is able to extract and use much of the heat from the gasses before the flue gasses dischage. This ablity to extract more heat from the fuel it consumes makes it more efficent and also reduces emmissions.

This ablity to extract more heat from the fuel it consumes makes it more efficent and also reduces emmissions.
There are three main types of high-efficiency condensing boiler- the combination or ‘Combi’, the system and the regular. Each type delivers the benefits of high-efficiency technology, but is suitable for different types of homes.
WHAT IS A COMBI BOILER?
The high efficiency condensing combi (or combustion) boiler is an ingenious space-saving idea, and an increasingly popular choice in Uk homes. the major diffrence between a combi and any other type of boiler is that a combi eliminates the need to store hot water, so there is no hot water cylinder. a combi is both a high efficiency water heater and a central heating boiler, combined (hence the name) within one compact unit.
The space savings result from the fact that as well as having no hot water storage cylinder, a combi dose not need a cold water storage cistern or other familliar components of a regular (conventional) heating system. the further benefits are a significant saving on hot water costs and the bonus of hot water delivered through your taps or shower at mains pressure.
WHAT IS A SYSTEM BOILER?
Unlike a combi, both a system boiler and a regular boiler work on the principle of stored hot water - but a system boiler differs from a regular boiler in two important respects.
Firstly, many of the major individual components of the heating and hot water system are built in, which means that installation is quicker neater, easier and less costly.
secondly, the hot water is pumped from the boiler through the system to the radators and hot water cylinder, resulting in fast response and more economical running costs.
WHAT IS A REGULAR BOILER?
If you are replacing an older central heating system, the chances are that it will have a regular boiler. A typical conventional system incorporates a boiler and controls, a feed and expansion cistern, and a hot water cylinder (usually in the airing cupboard) which is fed by a cold water storage cistern located in the loft.

| CONSIDERATION | MOST SUITABLE BOILER |
| You want to use your loft space for a room conversation or other purpose | COMBI |
| You live in a flat or bungalow (ie have very little or no roofspace) | COMBI |
| Your home has more than 2 bathrooms | REGULAR OR SYSTEM |
| Your mains water pressure is low | REGULAR OR SYSTEM |
| You want to replace an old boiler to improve an existing conventional central heating system | REGULAR, SYSTEM OR COMBI |
| there is a need to have hot water available on tap without waiting for it to heat up | COMBI |
SOLAR COMPATIBILITY
If you decide to have a new Worcester Greenstar system or regular boiler installed, it is worth bearing in mind that these types of boiler can be complemented by a Worcester Greenskies solar water system. this could provide between 50-70% of your annual hot water from a sustainable and free source of energy. even if the idea of installing solar water is something for the future, you can prepare for it now by asking your installer to install your new boiler with a twin coil hot water cylinder. this will save you money and inconvenience when you have a solar system installed.
