Why should I consider changing my boiler?


Older boilers can be as little as 60% efficient and even many comparatively modern boilers are still only 70-75% efficient compared to a new condensing boiler which is SEDBUK band A-rated which is more than 90% efficient.



What makes a condensing boiler so efficient?


Condensing boilers work by recovering the waste heat which is expelled through the flue system of a non-condensing boiler and passing it through a second heat exchanger where it extracts additional heat.


It could make a big difference to your household energy bills, saving you money and helping to reduce your carbon footprint at the same time. Changes to the Building Regulations mean that all new and replacement boiler installations are a high efficiency condensing boiler.


Which condensing boiler is right for me?


Every household is different, the heating and hot water needs of someone living in an apartment will

be very different from those with a large family home.  Each of the three types of boiler delivers all the benefits of high efficiency technology, so you just need to weigh up which suits your needs, the size of your home and your lifestyle and it’s easy to come to a decision on what’s best for you.


What is a ‘combi’ boiler?


A ‘combi’ or combination boiler is a high efficiency water heater and a central heating boiler combined within one compact unit. Water is heated directly from the mains eliminating the need for a hot water storage cylinder and the associated cold water storage cistern in the roof space. Hot water is delivered to your taps or shower at mains pressure this is very convenient and can save on your hot water costs. As an added benefit, showers from a ‘combi’ can be comparable with the performance of a power shower.

So a ‘combi’ can also give you a little extra room to play with, making it ideal for a flat or a bungalow with very little or no roof space and it’s also the right choice if you want to use your loft space for a room conversion. Another ‘combi’ benefit is that it can generally save you money on installation time and costs as well installation materials. ‘




What is a regular boiler?


Regular boilers (sometimes referred to as traditional or conventional boilers) are suitable for homes that already have a traditional heating and hot water system that require a separate hot water cylinder. Regular boilers also require a cold water storage cistern to feed the hot water cylinder and an expansion cistern in the loft. They are a good option for homes where a large volume of stored hot water is required such as those with two or more bathrooms, or in areas where the water pressure is low. Regular boilers are compatible with solar water heating systems to bring you the added benefits of environmentally friendly hot water and further cost savings.






What is a system boiler?


Both a system boiler and a regular boiler work on the principle of stored hot water. However, a system boiler is different in two important ways. Firstly, many of the components of the heating and hot water system are built into the boiler itself, making it quicker and easier to install. Secondly, it doesnt need a feed and expansion vessel in the loft. There are two kinds of cylinder which this type of system may have; a mains pressure hot water cylinder or a low pressure hot water cylinder. They are also compatible with solar water heating systems to bring you the added benefits of environmentally friendly hot water and reduced hot water and heating costs.
