  • 1. Boilers
    There are three types of boilers:
    • Combination boilers (also known as combi boilers)
    • System boilers (also known as sealed system boilers)
    • Regular boilers (also known as open vent boilers)
    For more information see the Guide to boiler types topic.
  • 2. Heat pumps
    These heating systems take their thermal energy from environmental sources such as air, ground or water; which is then converted into heating and hot water by the use of a heat pump. This is one of the most environmentally friendly and economical ways to provide hot water and heating for your home.

    • Sustainable energy
    • Quiet operation
    • Suitable for both radiators and under floor heating
    • Suitable for climate controlled systems
    • Low maintenance and long life
  • 3. Solar thermal
    Solar panels are a familiar energy technology that when combined with a modern heating system, provide a low cost source of hot water and heat. Solar collectors on the roof heat fluid in a sealed circuit which then heats up the water in a hot water tank.

  • 4. Storage cylinders
    Used to store large amounts of hot water for the heating system and the hot water system, ensuring that whenever you require hot water it is available. They can be combined with a variety of heating systems and are insulated to reduce the amount of heat loss.
    • Hot water is always available
    • Works with different heat sources
    • Wide range of water capacity
  • 5. Smart homes
    Modern technology allows the heating and hot water systems to be controlled by smartphones or tablets. This ensures that maximum efficiency can be drawn from these systems, with programmes being tailored to fast moving changes in the home schedule.
  • 6. Controls
    Modern household hot water and heating system controls are able to adjust the delivery to the requirements of the almost infinite demands of modern lifestyles. The accessibility of controls via smartphones and tablets means that heating and hot water is only used when needed.
