Heating - Plumbing Engineering Services Design Guide

Heating chapter from the CIPHE's Plumbing Engineering Services Design Guide.

Modern central heating systems have to be capable of meeting the user’s expectations of providing an adequate level of heating in an efficient manner. An efficient system is one that provides the correct amount of heat at the correct place and the correct time, burning the fuel used in the most efficient way possible, switching off the boiler when the demand is satisfied. Achieving this objective will require correct system design, avoiding inefficient oversizing of plant, and the use of appropriate controls.

However, the more sophisticated the system the greater the potential for problems, so good design often requires a compromise between what is the ideal solution and what is advisable in terms of operational and maintenance considerations.

The recommendations in this Guide relate primarily to domestic and small commercial installations with boiler input ratings not exceeding 60kW, although much of the content will also be applicable to larger systems.

Contents include:

• Building design / construction
• Calculation of heating loads
