High Efficiency 'Condensing' Boilers Vaillant high efficiency boilers use new energy saving technology to capture otherwise wasted heat and use fuel more economically - saving up to 35% when compared to an older existing boilers. All Vaillant ecoMAX boilers are SEDBUK Band 'A' rated and have efficiencies of over 90%.

Standard Efficiency Boilers Vaillant standard efficiency boilers offer efficiencies over 78% which also means considerable savings when compared to an older existing boiler. All Vaillant standard efficiency boilers are SEDBUK Band 'D' rated.

Combination Boilers As the name suggests a combination boiler supplies central heating and instantaneous hot water from the same single unit, and is therefore a ‘combination’ of both. It doesn’t need separate hot water cylinder and cold water tank, or the pipework and installation that would normally be associated with the more traditional system. Not only does it save space and supply hot water on demand it also eliminates the risk of water freezing in the roof-space during severely cold weather and makes installation simpler and faster.

System Boilers System boilers provide central heating and also supply hot water indirectly via a hot water cylinder sited typically in an airing cupboard. They have a built-in pump and equipment which enables them to be used on a sealed central heating system.

Open Vent Open vented heating systems are the typically older type or conventional system. Open vent boilers provide central heating and also heat a storage cylinder from which hot water is supplied. They need a separate pump and tank in the loft for the heating system.

Storage Cylinders Storage cylinders work with system and open vent boilers to store hot water which has been indirectly supplied by the boiler. The most efficient types are unvented cylinders which supply mains pressure hot water. These are purpose designed for use with system boilers. Vaillant VANTAGE unvented cylinder range is available.

Controls Used to provide both time and temperature control heating and hot water for maximum flexibility and efficiency. The following Vaillant high efficiency boiler ranges are available; - ecoMAX combination boilers - ecoMAX system boilers - ecoMAX pro open vent boilers
