The Worcester Bosch combi boiler range includes the market leading SEDBUK A rated Greenstar Cdi series, which is capable of creating a reduction in fuels bills by around 20%.

The combi range is easy to install as it operates with multi-directional fluing, and user friendly programming. They also provide a neat finish with a stylish frame that houses all pipe-work. At thetop end of the Greenstar CDi range is the The Worcester Greenstar 30CDi.  Additional features on this boiler include a holiday function, which provides frost protection that is economic to run while you are away from home. This boiler is capable of fully condensing in both central heating (CH) and domestic hot water (DHW) modes with a keep hot facility that guarantees instant hot water. One of the features Worcester Bosch are most proud of in this boiler are is low NOx and CO2 emissions.

The global energy crisis means that cutting down on these emissions is important and with the Greenstar 30 CDi Worcester Bosch has made an effort to be environmentally friendly. Safe affordable, economical and reliable it is little wonder the Worcester Bosch Greenstar 30 CDi has won awards from CORGI three years in a row.

What is a condensing combi boiler?

Wednesday, April 21st, 2010

A condensing combi boiler is a boiler that has a more efficient method of extracting heat from combustible fuel than a traditional oil or gas fired boiler. A huge amount of heat is wasted in a normal non-condensing gas or oil boiler in the form of hot flue gases that escape up the flue vent. This gas will be at a temperature of about 180C.

A condensing combi boiler is designed to let these gases rise as in a standard boiler but at the top the gases are redirected towards and cycled around a secondary heat exchanger, which draws heat from them, leaving them at a temperature of approximately 60C. Some condensing boilers even have dual heat exchangers, to extract even more heat from these waste gases.

This heat extraction and subsequent loss of temperature causes much of this gas to condense into water vapour, which then falls to the bottom of the flue, where it is channelled either into a pipe leading to the household soil pipe or into a separate drainage pipe that leads outside. A circulating fan then blasts the remaining waste gas up the flue and away from the property.

Compared to standard non-condensing boilers which peak at around 75% efficiency, condensing boilers can be anywhere from 83% to 92% efficient, giving them a SEDBUK rating of B or A respectively, the highest possible.
