How To Choose the Right Furnace For Your Home
Choosing the Right Furnace for your Home
A lot of homeowners are tempted into thinking that a larger furnace is better. After all, it is a long-term investment, and should heating needs increase in the future, the bigger furnace will suffice then instead of having to buy a new one.
A larger furnace generates more heat than you require or can use. The excess heat causes the furnace to “short-cycle” meaning it cycles on and off much more frequently than is normal. This, in turn, creates undue wear and tear on critical components, reducing the life expectancy of your heating system and resulting in additional breakdowns and part failures.
When a furnace or heating system is oversized, it also consumes more energy than necessary based on the overcapacity.The best thing you can do is buy the right-sized furnace for your home now.
How to generally determine the size of your furnace correctly
According to the US Energy Information Administration website, Indiana is in zone 2 of the US climate zones . This means that, on average, homes in the Greencastle area will require about 35-40 heating Btu's per square foot of conditioned space.
Measure the dimensions of each room separately, and use the lower end of the range if it is well-insulated and/or has windows facing either east or west (this means more sunlight and natural heat, lessening the need for furnace heating).
If not, use the higher value for the room. Adding up everything is the right way to arrive at how much heating your home needs, instead of using the total conditioned area and multiplying that against one of the two values mentioned for your zone.
When you request a free estimate for a furnace or heating system replacement from Royal Comfort, we conduct a very precise heat load calculation to determine the proper size system for your home. This calculation takes our local weather conditions into account as well as the following:
- Window type, quality, and square footage
- Insulation and construction factors
- Square footage of the conditioned space of your home
- Attic, crawlspace or basement considerations
- Air loss and leakage factors
It is an equally bad idea to buy a furnace that is sized smaller than what your home requires. While you are at it, you also need to look at how efficiently your furnace will work.
How to determine the energy efficiency of a furnace
Look for the Annual Fuel Utilization Efficiency (AFUE) rating. As of 2013, it cannot be less than 80%, according to US Department of Energy regulations. It must be at least 90% for it to be considered ‘high-efficiency’. The higher it is, the better. Some of the high-efficiency furnaces have an AFUE rating of 98.5%.
What an 80% AFUE rating means is that only 80% of the fuel is converted into heat. This also means that 20% of the fuel is wasted. In contrast, a furnace with a 98.5% AFUE rating converts 98.5% of the fuel into heat, resulting in only 1.5% fuel loss.
This translates into significant energy savings; sometimes up to $400 per season.
