Before you purchase a furnace for your home you want to ensure that you know about the main types of furnaces. You want to pay attention to the Annual Fuel Utilization Efficiency (AFUE) of the furnace. Whereas a conventional furnace usually has an AFUE of 60- 65%, a high efficiency furnace has an AFUE of 94% or more. Conventional furnaces waste a lot of money because for each dollar of gas you use you are wasting about 34-40%. A mid efficiency furnace has an Annual Fuel Utilization Efficiency (AFUE) rating of approximately 80% which means you can save 20 - 23% in gas heating costs compared to a conventional furnace. With a high efficiency furnace you can expect to save 30 - 38% in gas heating costs in comparison to a conventional furnace. A high efficiency furnace is a good investment, although it may initially cost a little bit more you will save money in the long run. High efficiency furnaces improve your home's comfort, are beneficial to the environment and save you money..
There are three basic types of mid and high efficiency furnaces including single stage, two stage and modulating. Single stage furnaces run at full capacity whenever heat is needed. One negative about the single stage furnace it is always running at 100% capacity, even if 50% capacity is all that is needed. Until you shut it off a single stage furnace will run at full capacity. For those of you who want to maintain a certain temperature in your home you will not find the single stage furnace ideal. A two stage furnace is better than a single stage furnace when it comes to energy efficiency. A two stage furnace runs in the first stage at 65% capacity and only kicks into full capacity when needed. When heating your home a two stage furnace is more efficient. A two stage furnace makes your home more comfortable because it eliminates temperature jumps. You will conserve more energy by heating your home at a constant temperature..
Since a modulating furnace provides 65 stages of heat output it is a good option for energy efficiency. By using variable speed and an electronically commutated motor (ECM) a modulating furnace reduces operating costs and runs your furnace a little quieter. Since they operate for a fraction of the cost of a regular furnace a modulating furnace will help you save significant amounts of money on heating your home. Reducing energy consumption by 80% is one of the great benefits of a modulating furnace. Not only do modulating furnaces increase air conditioning efficiency, they are also 24 times quieter than a conventional furnace. You can better control humidity in your home through your furnace with a modulating furnace. ECM blower motors modulate heat which improves temperature stability in your home. When hot air rises and cold air drops you are experiencing air satification, a common heating issue in many homes. A blower motor will prevent air satification in your home.
To help your furnace life a long life and run smoothly you should perform regular maintenance. Often, it costs more money to fix a furnace than regular maintenance would cost which is why you shouldn`t wait until your furnace breaks to take care of it. You should think about your furnace as a major home investment that is worth protecting with regular maintenance. If your furnace breaks and you can`t heat your home then you will risk frozen, broken pipes. Maintaining your furnace regularly helps decrease your heating bills and your energy use. Ensuring your filters and coils are clean is a part of regular furnace maintenance. In addition to having clean filters and coils make sure your exhaust fans, pumps and burners perform well.Many maintenance plans will provide additional warranty on your furnace parts. Pre-season is a when you should conduct your furnace maintenance. Regular maintenance ensures that your furnace will continue to meet efficiency specifications.
