What is the Vaillant range suitable for?

Vaillant specialise in combi and system boilers, with a wide range available to suit different size homes and heat and hot water demands. When choosing your new boiler, you need to firstly consider what is the most suitable type and size of boiler for your home, heat and hot water demands. Gas condensing combi boilers are the most popular boiler type in the UK because of their efficiency and compact size. Combi boilers are best suited to small to medium sized homes, such as a 2 or 3-bedroom semi-detached house. However, if you have a larger property such as a detached house with 4 bedrooms and multiple bathrooms, a system or heat-only could be a more suitable boiler type to provide the amount of hot water you require.

The kW output is determined by the size of your house and number of radiators; generally, the higher the kW output of a boiler, the more demand for hot water it can cope with. If you need help determining what kW output you require for your Vaillant boiler, you can use the following as a guide:
