We have come a long way in heating since the early days of gathering wood for a fireplace. Nowadays, we can be grateful for gas-fired furnaces that keep us warm. And with the creation of the modulating furnace, there’s even more benefits.
Furnace technology itself has developed over the years. If yours is nearing the end of its life, call us at Tiger to have it replaced! Continue below to learn more about the benefits of modulating gas furnaces.
Types Of Furnaces
Furnaces can be classified according to their burner operation. There are three main categories: single-stage, two-stage, and modulating.
Single stage furnaces are either on or off. When the thermostat temperature drops below the set point, the furnace comes on and runs until the temperature reaches the desired level. Then it shuts off until the temperature drops again.
Two stage furnaces operate at partial capacity and full capacity depending on the heating requirements. This allows your furnace to use less energy when less heat is needed. Its efficiency is slightly better than that of a single stage furnace.
Modulating furnaces vary the output to match the heating demands. This means they don’t come on and off every time the temperature drops. They run almost continuously, just heating in smaller increments. This has several benefits.
Modulating furnaces keep your home at a steady temperature
Single-stage furnaces can vary your home’s temperature by as much as six degrees. So while they are capable of providing the right amount of heat, that heat isn’t always consistent. You end up shivering as you wait for the furnace to come back on. Modulating furnaces maintain your home’s temperature by constantly providing the right amount of heat.
You Save Energy With a Modulating Furnace
Even though modulating furnaces run for longer hours than a standard furnace, they rarely run at full capacity. This decreases the overall amount of fuel used. Single stage furnaces also consume more energy at startup, further increasing their consumption. Modulating furnaces don’t have this issue, they slowly ramp up and down as needed.
Improved Air Quality
Having your air flow continuously through your filters allows for cleaner air. You can choose to keep your fan running continuously for a single stage furnace, but it consumes more electricity than a modulating furnace.
