AM14 Non-Domestic Hot Water Heating Systems

CIBSE, working with ICOM Energy and experts from the manufacturing, design, and installation and commissioning sectors, have produced this Applications Manual, giving comprehensive guidance on the design, installation, commis­sioning and operation and maintenance of heating systems (it does not cover medium temperature or high temperature hot water systems i.e. those having flow temperatures above 90 °C).

It also addresses the two very different aspects of design: that intended for a new building, and that for a refurbishment or retrofit project.

This publication should be widely read and used by all those responsible for heating systems in non-domestic buildings, and should contribute significantly to providing better heating in many buildings.
