ABSTRACT
Terminal heat emitters, such as radiators, convectors andwarm-airmethods, pipework layouts, and pipe and pump sizing are discussed. Oil-firing equipment is described and the combustion process is analysed. Basic flue arrangements are shown. Heating systems only operate at their design heating duty when the outside air
temperature coincides with that used for heat loss calculations; the commissioning engineer needs to relate heating performance on the day of test to the design figures. Such calculations are shown. Electricity is generated at the expense of usable energy discharged to the atmosphere
or the sea. The plant needed to convert this surplus into saleable heat for district heating is outlined. Interest in this subject will develop for various reasons, and the United Kingdom lags behind other European countries in the employment of combined heat and power stations. The control and operationalmonitoring of heating, air conditioning and other build-
ing services has been enhanced by the use of computer-based techniques known as building energy management systems (BEMS). These are explained and clear links with other services are shown.
