What is a resistance furnace?
Resistance furnace generates hot air that is used to heat the house. Blov inside one creates air flow using electricity. The air then spreads the heating elements inside the furnace. When air is heated, it is sent throughout the building using different channels. As a result, the flue duct is not required for this type of heating system. In general, these models cost less than oil or gas furnaces. Since they run on electricity, their normal operating costs are usually higher than the combustion furnaces. The thermostat is connected to the relay inside the furnace. This relay is fastened by the heating elements when more heat is needed. The air circulation is placed either on the thermostat in the house or on the furnace itself, also allows the house owner to constantly run the blower. This keeps hot air all over the house.
While maintenance costs are low compared to other system heating costs, some minor maintenance may be needed to maintain effectively during resistance. These types have airThe filters that must occasionally be cleaned to prevent them from clogging. Clogged air filter can slow or turn off air flow.
The furnace usually has a main circuit breaker located near or in the main electric panel of the house. Home owners should ensure that this main circuit breaker is off before any repairs on the furnace. Switching off the circuit breaker will help prevent shocks or other injuries during such routine work.
The elements inside the furnace also have uniform circuit breakers to prevent overload. If heating does not work, it may be necessary to reset the circuit breakers. When the heat is on but insufficient, the elements themselves can be replaced. In general, only a professional technician should work on heating elements.
Resistance furnace can also be used in conjunction with a heat pump to heat the house. The heat pump will operate separately until the temperature drops below a certain Regionalovn. At this point, the furnace will turn on and work with a heat pump to keep the house warm to a comfortable level. The house owner determines this level using the thermostat settings.
