How to use heating and hot water systems efficiently

Installing efficient heating and hot water equipment


Whether you are investing in a new heating and hot water system for your building, or upgrading an old one, you should make sure your equipment is energy efficient.

When constructing or altering a building, you must ensure that any new heating equipment meets or exceeds the energy efficiency targets in Part F of the Building Regulations

It may be more efficient to install additional small boilers for use in the summer months. For example, installing a separate water heater will help you save money by letting you switch off the main boiler system during the summer.

Various types of energy-efficient equipment are available, including:

  • advanced metering systems
  • optimiser thermostats
  • zone controls for space heating
  • sequencing controls
  • heat recirculating units to recycle warm air in roof spaces

Renewable energy systems, such as solar water heating and wood-fuelled boilers, are another way of increasing building energy efficiency. They can also help you reduce your business' carbon emissions - see how to generate your own renewable energy.

You can get advice on the best type of equipment for your premises from the Carbon Trust. Alternatively, you can contact specialist associations, such as the Heating and Ventilating Contractors Association (HVCA) or the Council of Registered Gas Installers (CORGI).
