The particular needs of each individual cus- tomer can be filled too. There are three broad cate- gories of electric heating sys- tem: j 1. Unitary or room-by- room, including the various in- dividual fixtures; 2. -- Radiant cable, a method peculiar to electric heating; 3. -- Central including warm air and hydronic systems. Here's a rundown of the main features of each type: UNITARY SYSTEMS Unitary type resistance heat- ers are among the most flexible}thermostats. Because they are of heating equipment. They in- clude baseboard, wall convector units, radiant panels and fan type units. They are normally installed with thermostat con- trols in each room. Heat is provided in each case by the passage of an electric current through a form of resis- tance wire or element which gives off direct heat. The big advantage of this sys- tem is that. heat can be con- trolled accurately: when a par- ticular room or area is not in use, its temperature can be re- the floor. This allows for ade- quate air circulation. Baseboard heaters are de- signed so that free air flow through the heating elements keeps the surface temperature to a level which will feel hot to the touch, but will not burn. However, even if the air flow is restricted by objects thrown behind or over the heater, the unit will not overheat because safety cut-offs shut off the elec- tricity. CONVECTORS Wall mounted convector units, with or without fans, are ideal for both new house installation or conversion work. Because they are available in a wide range of sizes they can find application in most rooms in a home. Larger units can be used in recreation rooms, enclosed porches and similar locations. Smaller units are suitable for bathrooms, entrance lobbies, 'dens, mudrooms, etc. | Most units come with integral |designed to fit within the stud |space there is very little if any ing elements. a forced alr blow- er, filters, and controis to tie these components together, packaged in one cabinet. Heat is distributed through a duct system with supply and re- turn ducts, just like a conven- tionally-fired warm air system. Two or more thermostats can be employed to zone supply air to specific areas of the home. Electric central furnaces do not require a flue or vent, since they use no combustion air. They can be installed in any convenient space in the house, vertically or horizontally. DUCT HEATERS In-duct and boot heaters are similar to unit heaters, installed in the ducts or outlets of a forced-air system. They are best used. in con- junction with a continuously op- erating fan, can also be incor- porated into a central cooling system, Because each room or area has its own heating unit, such heaters offer the same kind of precise temperature control as the unitary systems described above. projection into the room.

Each of them provides for installation of eiecironic air filtering, humidification, dehu- midification and cooling. HEAT PUMPS The heat pump does two jobs: heating and cooling. In winter, it extracts heat from the outside air and con- ducts it into the home. In sum- mer, the operation is reversed; heat is taken from the house and expelled into the atmos- phere outside. This principle is like the oper- ation of a household refrigera- tor, and is very different from resistance heaters such as base- 'board, cable and panel heating equipment. In the case of the heat pump, the energy obtained from the heat source (usually the air out- doors which, even at below zero temperatures still contains heat) together with the energy output of the heat pump compressor, is delivered to the condenser coils and, from there, throughout the) home. This is usually done through a conventional air dis- tribution system. additional system for cooling can make up for the cost dif- ference. Heat pumps are most efficient at temperatures above 40 de- grees F. In extremely cold cli- mates, supplementary _resis- iance heaiers have io be pro- vided to maintain a comfortable temperature. The reason for this is that the heat pump ca- pacity is usually designed to} handle the air conditioning load. | HYDRONICS | Latest development in electric} heating systems are central electric boilers, much like oil- or gas-fired boilers.
