Good practice with heat pumps

B&ES, Building & Engineering Services Association, heat pump, space heating

The Building & Engineering Services Association (B&ES) has updated its TR30 good-practice guide to heat pumps. This 50-page guide is designed to help building-services engineers specify, design and install heat-pump systems. This guide covers packaged heat pumps with electrically-driven compressors, usually found in housing and small commercial premises.

These systems are generally based on packaged heat-pump equipment where components and controls for the refrigerant circuits are pre-assembled and tested. The emphasis in the guide is therefore on the installation of these packages within an overall heating and cooling system.

Bob Towse, head of technical and safety at B&ES, explains, ‘Heat pumps are increasingly important in many space-heating and domestic-hot-water applications and are increasingly used as an alternative to conventional boilers.

‘The document provides an overview of the different heat-pump applications, with their benefits and limitations, as well as giving some outline design information for each of them.’
