Electric Resistance Heating System

Whenever an electric current flows through a material that has some resistance i e anything but a superconductor it creates heat.

Electric resistance heating system.

Electric resistance furnaces simply use electricity to heat the air and send it into your home. Electrical resistance heating erh is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and evaporate contaminants. The advantage over a heat pump is the air is typically warmer than air blown from a heat pump system. See our video explanation of how heat pumps work for greater detail.

Electric current is passed through a targeted soil volume between subsurface electrode elements. This is the one exception to the rule of equal efficiency as it is not electric resistance heat but electricity is powering a condenser and a fan. The heating element inside every electric heater is an electrical resistor and works on the principle of joule heating. An electric furnace works like a big hair dryer producing heat with electric heating elements.

The resistance to electrical flow that exists in the soil causes the formation of heat. Electric resistance heat can be supplied by centralized forced air electric furnaces or by heaters in each room. Today s heat pump can reduce your electricity use for heating by approximately 50 compared to electric resistance heating such as furnaces and baseboard heaters. Observed that the concrete with nickel particles has a superior self heating.

The heating power per unit area attained by the steel fiber concrete was 750 w m 2 much higher than 340 w m 2 for a metal wire with the same resistance note. This resistive heating is the result of friction as created by microscopic phenomena such as retarding forces and collisions involving the charge carriers usually electrons. In formal terminology the heat corresponds to the work done by the charge. An electric heater is an electrical device that converts an electric current into heat.

The heating power per unit area shows the heating capability of the self heating concrete. This system allows homeowners to avoid the chore of ordering propane. Types of electric resistance heaters. The blower and element activate when you turn up your thermostat to match the desired temperature.

This makes electric resistance heating less efficient and more expensive than traditional combustion appliances. A heat pump powered by electricity and not gas would also qualify as electric heat. Room heaters can consist of electric baseboard heaters electric wall heaters electric radiant heat or electric space heaters it is also possible to use electric thermal storage systems to avoid heating during times of peak power demand. Electric resistance heating normally comes in the form of portable space heaters baseboard panels connected to the lowest part of the wall or electric radiant heating in floors walls and ceilings.
