At the flick of a switch
Electricity is an attractive fuel for home heating because it is 100 per cent efficient, clean, available at the flick of a switch, flexible to use and accurately controllable, It does not require any storage or a flame to operate.
Electric heating systems fall into three basic categories: • Portable heaters which are plugged into a standard power point. • Permanently installed heaters which because of their design or electrical requirements are permanently installed and connected to special wiring. • Central heating: whole home heating systems which require considerable installation work and may incorporate ducting, which shifts heat to selected rooms from a central heating unit. These systems can be built up over a period of timew In all these categories there is a choice of heaters which produce radiant or convected heat, or a combination of the two. All permanently installed heaters and central heating systems are available with built-in
automatic timing and/or temperature control. So are many of the portable variety. Timers can be pre-set to turn heatets on and off at chosen times while thermostats help maintain a constant temperature at your comfort level. Both devices can help to lower
running costs and increase comfort. Any type of heater can be used to heat the rooms of a house, but because they all have different performance characteristics, you will achieve the best balance between effectiveness and economy by understanding each heater's strengths and weaknesses, and using them in their most suitable applications. • Portable high temperature radiant heaters heat the surface
on which they shine. They are most economical to use in heating a small area in a large room, such as when people are grouped around a television. They are ideal for providing a quick burst of heat over a short period. Larger units with a range of heat settings and temperature setting and high quality reflectors produce the best results. These units set up a warm convection
