Pressurisation of Closed Heating and Cooling Systems (BG 82/2022)
The maintenance of acceptable pressures whilst accommodating thermal expansion is one of the key factors in ensuring continuous and correct functioning of heating and cooling in buildings. Correct pressurisation prevents system failures, thus saving building owners time and cost related to system downtime and repairs.

Pressurisation of Closed Heating and Cooling Systems (BG 82/2022)
This guide explains the principles of pressurisation, the different types of equipment used, and the calculation procedures following both British and European standards. The guide has been developed with a steering group of industry experts, following discussions on the importance of pressurisation, in the context of closed heating and cooling systems. Correct pressurisation prevents system failures, thus saving building owners time and cost related to system downtime and repairs.
