Boiler types: which would suit your home best?

Here are a few examples and guidelines to think about and help you identify the type of condensing boiler most likely suited to your needs. We've added images underneath to show you how the different type of boilers work and what the impact is on your living circumstances.

Consideration:
You want to use your loft space for a room conversion or other purpose
Most suitable boiler: COMBI

Proven technology to guarantee central heating system protection

MagnaClean® Professional sets an industry standard for plumbing and heating engineers when it comes to protecting and maintaining both new and existing heating systems.

In an age of advances and high efficiency gas and oil boilers there has never been a greater need to safeguard what amounts to one of the most expensive investments in the modern home - the central heating system.

Even a small build-up of iron oxide in a standard or modern efficiency boiler results in substantial efficiency loss and fuel wastage.  So, not only does the system perform inadequately, it also costs more to run and maintain.

MagnaClean Professional is a proven, high efficiency, full-flow magnetic filter designed to tackle all central heating systems removing virtually 100% of the suspended black iron oxide.  The benefits of this simple technology are immediate:

• Simple installation and effortless servicing saving time and money
• Immediate results and system protection following installation
• No ongoing running costs
• Quick and easy chemical dosing
• Long operational life AND guaranteed for TWO years

T Cosgrove, Glasgow's first port of call in Plumbing in Heating Services installs a MagnaClean® Professional filter to the boiler return pipe work. Always!

Greenstar CDi boiler series by T Cosgrove

The Greenstar CDi boiler series is part of a market-leading range of energy-saving condensing gas-fired boilers from Worcester. They can cut heating and hot water bills by between 15-20% - and they’re up to 30% cheaper to run than an older boiler.

Greenstar condensing boilers deliver this energy-saving performance by recycling exhaust gases to extract and re-use latent heat - a highly efficient use of energy which also significantly reduces carbon dioxide in the atmosphere.

• SEDBUK* A-rated efficiency - environmentally friendly
• 27kW, 30kW, 37kW and 42kW DHW outputs - a boiler for all property types
• Hot water and central heating temperature controls - consumer comfort and flexibility
• Mechanical, digital and radio frequency (RF) control options all available
• Optimising 7-day programmable room thermostat available
• 24 hour programmable room thermostat available
• Holiday function – frost protection and economic to run while you are away from home
• Keep hot facility - instantly available hot water
• Wall mounting frame housing pipes behind it - no exposed pipe work
• Fully condensing in both central heating (CH) and domestic hot water (DHW) modes
• Low NOx and CO2 emissions - environmentally friendly
• 2 year** warranty with 10 year** warranty on primary heat exchanger

Condensing the vapour

Condensing

The term 'condensing' is derived from the creation of condensation within the heat exchanger or flue. This liquid will need to be conveyed away to a drain via a plastic discharge pipe run by the installing engineer. When combustion of any kind takes place water vapour is always produced. In a 'standard efficiency' boiler the flue gas temperature is kept relatively high to avoid condensation and its related issues. But in a high efficiency boiler, so much of the heat produced in the combustion process is absorbed by the heat exchanger into the heating water and very little is wasted to the atmosphere via the flue, hence less fuel is burned to achieve the same results but the consequence is condensation which is dealt with in the appropriate manner.

Taking the mystery out of SEDBUK ratings

SEDBUK was developed under the UK Government’s Energy Efficiency Best Practice Programme with the involvement of boiler manufacturers, and provides a consistent basis for the comparison of the energy performance of different boilers. It stand for "Seasonal Efficiency of a Domestic Boiler in the UK"

To simplify the assessment SEDBUK ratings are from A to G, A-rated boilers being more than 90% efficient. Only A rated boilers - having efficiencies of over 90% carry the energy saving recommended logo.

Boiler efficiency is important to you. Not only does an efficient boiler produce less CO2 it also consumes less fuel for the same heat output - this will reduce your gas heating costs.

Remember the purchase price is paid once only, the heating costs are paid every year and any saving is repeated year after year.

When Traditional boilers burn gas to producing heat for heating your water and radiators they eject waste gases through the boiler flue. These waste gases can be 120-200ºC and hence the system is inefficient ejecting significant heat to the atmosphere. This is energy you have paid for.

Modern condensing boilers have large heat exchangers designed to extract the heat from these hot flue gases. Current heat exchangers can reduce the temperature of the ejected gases to below 100ºC and sometimes as low as 50ºC for the most efficient. This extracted heat is used to heat your home and improves the SEDBUK measured efficiency of the boiler to over 90%, a SEDBUK A rating.
