Footage description: Brian Trueman, walking down a residential street, introduces the programme. Trueman, inside a house, points out that comfort doesn't necessarily depend on room temperature. He explains that activity, type of clothing and type of furniture all have an important bearing on comfort. An animated cartoon illustrates one method of heating common to home heaters - radiation. Trueman, with a disassembled electric bar fire, explains how it works. An animated cartoon illustrates a second method of home heating - convection. Trueman goes on to demonstrate the existence of convective currents by creating smoke over a convection heater. Trueman, looking at several types of home heaters, explains that they all work by a mixture of the two methods of heating. An animated diagram of a central heating system helps to illustrate his points. Trueman examines various methods by which the heat generated in the home can be controlled. Shots of various switches and thermostats as he talks as well as an animated diagram of a central heating system. Trueman goes on to give some tips on the economical operation of control devices. Bob and Francis Critoph, in their home, explain what heating systems they have in the house. They go on to explains some of the tips on energy saving which they got from studying this course. Brian Trueman, outside a house, uses an infra-red camera to discover areas of maximum heat loss from the building. He contrasts the heat loss from windows without curtains and with curtains and also the effect of placing an aluminium sheet behind a central heating radiator. The programme winds up with a song 'Lag your legs' bv Harvey Andrews, which stresses the personal factors which can save energy.
