What Are Electric Furnaces and How Do They Function?
Electric furnaces are heating machines containing an enclosed metal box holding an electric heating element and a blower fan. Like their oil and gas burning complements, electric furnaces are thermostatically controlled forced air units, switching on mechanically when a thermostat senses the temperature of the building has released below the set point. With the heating element on, the internal blower fan also changes on automatically, blowing air over the heating element, and then allocating the newly warmed air through a network of ducts to where it’s needed in the building. When the set temperature is attained, the heating element and blower fan shut off until they’re wanted again.
Electric Furnace Portions and Landscapes
Heat Fundamentals: Thick bands or wires made of electrically resilient metal (usually a mixture of nickel and chromium). When electricity is nourished into these, the electrical resistance produces heat.
Heat Communicates: These regulate how much electricity is fed into the heating elements.
Plenum: A small air compartment area in the furnace that collects air and helps it circulate more professionally.
Power Spread: This regulates how much electrical power the furnace magnets.
Electrical Modifier: This lowers the received voltage (240 volts) to a voltage working by the furnace’s control elements (often 24 volts)
Blower or Blower Fan: Interior motor fan that blows cool air over the heating element, then forces that air into the ducts, heating the building rendering to the thermostat’s settings.
Return Air Ducts: These pull unheated air from the building into the heater where the blower fan forces it over the heating element.
Filters: Household air is naturally full of flying dust, fuzz, and wreckage. Filters keep this unsolicited substance from entering the furnace and being pushed through the channels by the blower fan, and into other parts of the building. Filters should be substituted every few months (check your owner’s manual for the manufacturer’s precise recommendations) to keep your furnace running optimally.
Sequencers: Many electric furnaces have numerous heating elements. Sequencers control when each of them is turned on and off as heat is required, allocating the electrical load consistently.
Thermostat: Combined with the furnace, the thermostat controls when the heating elements and blower fan come on and off, switching them on when heat is required, and off when the set temperature is touched.
Pick an Energy-Efficient Model
If you’re selecting to devote to an electric furnace, the first thing you’ll want to do is look for an energy-efficient model. That’s because heating costs account for nearly half of the average American family’s energy bills. When you upgrade to an energy-efficient model, you’re able to change costs and stop tossing money out the window.
Fresher heaters on the market today use 30 percent less fuel and energy than grownup furnaces. If you haven’t simplified your furnace in quite some time, then it’s a good idea to reflect an upgrade. In addition to the cost savings, newer furnaces are far softer and less troublemaking than outdated models. They also have many other features, including upholding the temperature of your home at a more reliable level.
Entek offers reasonable, high-efficiency Carrier electric furnace models that will help you cut your energy costs. Furnaces and boilers are allocated an efficiency rating known as an AFUE, annual fuel utilization efficiency. The advanced the rating, the more energy effective the home heating system. Electric furnaces have an AFUE rating characteristically in the range of 95 to 100 percent.
Obtaining the Accurate Unit
If you’re in the marketplace for an electric furnace, there are a few things to look out for when you’re spending around. First, you want to be sure that the heater you select has the ENERGY STAR® label. This label specifies that the product will help you save money on energy bills while also helping defend the environment.
It’s also vital when determining the brand of electric furnace to buy to associate warranties. You’ll want to select a dependable unit that’s guaranteed to be valuable speculation. Be sure to also check out some reviews for any of the brands you are seeing. This will help you understand the type of knowledge other customers have had with a particular unit and can be useful in helping you slender your search so that you find the best conceivable electric heater for your home.
Select the Appropriate Size
We can’t strain this enough. It’s so significant to purchase a unit that’s been correctly sized for your home and to also have it professionally connected. If you select the improper unit size, your boiler will not operate at maximum competence.
So how precisely do you control the right size furnace for your home? First, you’ll want to control the geographic weather zone for your home. This map is a good place to start. For example, if you live in Washington or Oregon, you’re located in either Zone 3, 4, or 5. For the determination of this example, we’ll use Zone 4 for our calculations.
Those living in Zone 4 have a BTU (British thermal unit) range of 45 to 50. Once you’ve resolved your zone range, the next step is to choose the right number within that range. If your home is well insulated, you’re going to select a number in the lower range. If your home is unwell cloistered, you’ll want to choose one of the higher numbers. We’ll select BTU 45 for our example.
Next, you’ll want to control the square footage of your home and multiply that by your BTU number. For example, if you have a 2,000-square-foot home, then you would multiply 2,000 by 45 to come up with 90,000. This is the number of BTUs obligatory to heat your home, so you’ll want to select an electric furnace that is accomplished by this output.
