Typically referred to simply as a ‘combi boiler’, a gas combination boiler is a single compact unit that combines a central heating boiler and high-efficiency water heater.
Our combi boiler range is designed for maximum energy efficiency. This means that by choosing a Viessmann combi boiler you will be saving on your energy bills and helping to protect the environment.
Our entire combi boiler range is rated energy efficiency class: A.
All of the boilers we provide are built around our long established reputation for high quality heating systems and are equipped with the latest heating technology.
Gas condensing combi boilers provide both heating and hot water on demand. In other words, these space-saving units heat water when it is required, rather than heating it and storing it for use later. This means they don’t require you to have a hot water storage cylinder or a cold water storage tank - as are found with conventional boiler systems. They are quick and easy to install because they have fewer external components than alternative heating systems.
These energy efficient combi boilers are connected to the mains water supply and are on continual standby. When a tap is turned on, they heat the water through a heat exchanger, giving you hot water when you need it regardless of the time of day or night.
Because they eliminate the need for water tanks, they can provide you with extra space in your home. This can be a particular benefit in smaller properties where square footage is limited.
Modern gas condensing combi boilers are designed to be extremely energy efficient. Unlike older non-condensing models, which can waste a considerable amount of heat in the form of hot gases that are released from the flue, condensing boilers capture some of this heat energy and use it to heat up water returning from the central heating system. This means that more of the money you spend on gas will be converted into warmth for your home.
Gas condensing combi boilers are the most popular choice of heating system in the UK and for many households, they provide the most effective and efficient heating and hot water solution. We provide a variety of models designed to accommodate different needs.
