Benefits of a Viessmann combi boiler

Combi boilers are becoming an increasingly popular choice in UK homes due to their space-saving functionality. You may choose a combi boiler for the following reasons:

  • Compact sizes make combi boilers ideal for smaller properties
  • Only one unit is needed to deliver heat to your radiators and hot water to your taps
  • No requirement for a separate pump, hot water cylinder or cold water storage tank
  • Hot water is delivered to your taps and shower at mains pressure
  • No risk of cold water storage pipework freezing in the loft
  • They have the ability to adapt to heating demand without constantly switching on/off, meaning smoother operation, less wear and tear on components and greater reliability
  • Comprehensive warranty on the entire range, as standard
