Combi Boiler

System_Boiler_UnventedWhat is a ‘combi’ boiler?
A ‘combi’ or combination boiler is a high efficiency water heater and a central heating boiler combined (hence the name) 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. Because your hot water is delivered to your taps or shower at mains pressure it’s 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.
‘Combi’ boilers are so popular that they account for two out of every three new domestic boilers installed in Britain every year.

Regular Boiler

regular_boiler_layoutWhat 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 requires 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 any home where a large volume of stored hot water is required e.g. homes 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.

System Boiler

System_Boiler_LayoutWhat is a system boiler?
Both a system boiler and a regular boiler work on the principle of stored hot water – but 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 doesn’t 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.
