Advantages and Disadvantages
Electric heating is clean compared to forms of heating that involve combustion, eg gas, oil, coal, etc. There are no fumes or associated flue gases. It is usually cheaper and easier to install than other forms, whether in a new construction or in an existing home. It can be conveniently used as & # 39; up up & # 39; heating, where gas or other central heating is used as the main form of heating. Many (but not all) electric heaters are portable and react quickly.
It is generally more expensive to operate, despite the relative costs to gas, for example, that depend on local conditions and costs at a given time.
The operating costs of electric heaters will be high if the heatsink does not have a thermostat and will remain on for long periods of time, unless it is a low power heatsink. So only use a high-powered heater without a thermostat, it is only used to heat a room for a short time and then turn it off. Plug-in thermostats can be used to provide external temperature control for heating. Many heaters have a jelly watch. the settings, which only activate the heater if the temperature is freezing, making it a useful precaution against exploded pipes.
Many heaters have timers that turn them on and off automatically at predefined times. You will have to pay extra for this, and often it is cheaper to buy a 24-hour plug-in timer to use with the heater.
The main forms of electric heating are:
These are electric heating cables laid under the floors. (Pipes containing hot water heated with gas, or other fuel, are another form of underfloor heating.) I would only consider this in a new construction. The cost and disruption of the underfloor heating installation in an existing property is considerable.
These are large, wall mounted heaters, which use peak (cheaper) electricity during the night and store the heat for the release slowly during the day. Special wiring and off-peak meters must be installed, and the electricity supplier must arrange for you to be de-energized. rate. This is an option to consider if central heating is required and if gas or other fuels are not available. This is probably the cheapest form of central heating to install, but it can be expensive to operate. It does not respond quickly to sudden changes in temperature. If there is a sudden cold snap during the day, it will not be until the next night that the heating settings will come into effect.
They are cheap, small, portable and heat quickly. They are perfect for additional heating. They can also be used in summer only as fans. Fan noise can however be irritating, and if that is a consideration, it is best to use convectors.
Again ideal for auxiliary heating, but slightly slower, bigger and more expensive to purchase than fan heaters. They can be on the floor or on the wall. They are almost silent however, with the exception of fans, which do not seem to have any advantage over smaller and cheaper blower heaters.
These are very thin wall radiators. They occupy a large wall area. They usually do not have a thermostat, they are all the time.
Oil Bath Radiators
They look like conventional central heating radiators. There are flat furniture that can be wall mounted, and wider, on wheels, so that they can be moved to different rooms. They are slower to respond than fans or convectors, but some people prefer their lower temperature over a larger area.
Tubes ranging in length from approximately 350 mm to 2000 mm (1 "to 6") in length. They are usually wall mounted. They are very low power (about 150W per meter) and do not have a thermostat. They are normally used in greenhouses, animal cages, aeration compartments, behind refrigerators and freezers in outdoor homes where it is too cold for the refrigerator to operate normally, and so on.
The heater must either be operated by a pull switch, or externally, from another room. The latter would typically be a wall-mounted panel heater (these can be supplied with towel rails to dry towels as well). The first could be a downflow radiator or radiator, mounted on a wall near the ceiling, for which wiring should be installed, or a heating / lighting unit, replacing the existing luminaire. Heat bulbs / 250 W bulb can also be placed in an existing lighting unit (without using lampshades) to give a little warmth.
These may range from cheap radiant heaters, or newer halogen heaters, to coal fires, expensive logs or fire, often used as focal points for a room. These usually combine radiant and convection heating.
Other Electric Heaters
Air curtains, baseboards, etc. usually use natural or forced convection, designed to adapt to a particular place, such as above a door or in a pedestal. Ceramic and quartz radiators generally use a mixture of radiant heat and convector and are often more powerful than conventional domestic radiators, making them useful in industrial applications.
