Which Fairfield Heating Replacement to Choose

There are many types of heating systems to choose from. Single-stage models are the most affordable, but they have their limitations. Since they only have one setting, this type of heating installation is best-suited for small, single-story homes that don’t require a lot of temperature regulation.
A two-stage furnace replacement has a dual power mode that can help even out the temperature throughout larger homes. So, if you have a home that tends to get drafty in certain rooms or spots, you probably need a two-stage furnace to keep your home comfortable throughout the cold weather. Additionally, two-stage furnaces run at lower power settings, requiring less energy than single-stage models.
For maximum energy savings, albeit at a much higher price point, customers often choose a modulating furnace with several settings. This type of heating replacement will improve on-the-nose temperature settings and even out the temperature throughout your home in Fairfield.
Heating Replacement Can Save You Money
In recent years, heating technology has made great strides in terms of efficiency. This means that if you get to the stage where you need to replace your furnace, you’ll most likely find that your yearly utility bill will decrease substantially.
The efficiency of a central boiler or furnace is measured by AFUE (annual fuel utilization efficiency). AFUE is an indication of how efficient an appliance is in converting energy from fuel to heat during a typical year. By law, new boilers and furnaces have to display their AFUE rating so consumers can easily compare various models’ heating efficiencies.
When evaluating a system’s efficiency, you should not only look at its AFUE but also at the equipment’s features.
High-efficiency systems have a 90% to 98.5% AFUE, sealed combustion, and extra efficiency is achieved by condensing flue gasses in a second heat exchanger. Mid-efficiency systems have an 80% to 83% AFUE, a flue pipe with a small diameter, and reduced cycling losses thanks to their compact size. Also, there’s no pilot light or electronic ignition to deal with. The flow of combustion gasses and combustion air is controlled by an exhaust fan. Low-efficiency systems operate at 56% to 70% AFUE. You have to ensure the pilot light remains on continuously and deal with variable performance due to natural drafts.
