Furnace Efficiency Ratings

Posted on: January 24th, 2017 by Derek Barmer No Comments

 

UnknownDid you know that the efficiency rating for your heating system will help you figure out how much it will cost you to heat your home? A higher rating is ideal — it means that a greater amount of heat is provided for the amount of energy used.

The Annual Fuel Utilization Efficiency (AFUE) rating indicates how much heat the furnace produces compared to the amount of energy required to produce the heat. For example, if a furnace is rated at 80 percent AFUE, 20 percent of the energy used is lost, and 80 percent actually becomes heat.

By finding out this information you can decide if it may be time to upgrade your system. Contact the manufacturer or search on their website to find your model.

Here is how the efficiency ratings for systems break down:

  • 56-70% efficiency (typically older models)
  • 80-83% AFUE- mid-efficiency
  • 90-98.5 AFUE- high-efficiency

Keep in mind that the AFUE rating does not account for potential heat loss through duct work. Ducts can lose a lot of heating efficiency.

High-efficiency furnaces use two heat exchangers. Condensing units remove water from exhaust gas and then send the gas through a second exchanger. The combustion units are sealed. Condensing furnaces are generally about 10 percent higher in efficiency ratings than non-condensing units. These systems are more expensive initially, but you can save a great deal of money over the long term in fuel costs. An HVAC professional can help you decide what is best for your home and lifestyle.

Using Space Heaters

If you’re trying to warm up a certain room, a space heater can be a great way to do that. However, the space heater’s effectiveness is dependent on you taking specific precautions while purchasing wisely so you don’t waste electricity (and money).

There are a few different types of heaters that can be used in your home. Electric space heaters are the only unvented space heaters safe for indoor use. They do not pose indoor air quality concerns, but can still be a fire hazard if not used safely. These should be plugged directly into a wall. If an extension cord is absolutely necessary, use a short heavy-duty cord of 14-gauge wire or heavier. Look for a tip-over safety switch that shuts the unit off if it is turned over.

Vented combustion heaters, on the other hand, are made to be put next to an outside wall so the flue gas vent can be installed through a ceiling or wall (unvented combustion units are not recommended for indoor use). Only use the approved fuel and do not overfill the heater or fill when it is still hot. It is a good idea to have a vented space heater inspected by a professional each year to prevent issues that can cause high levels of carbon monoxide to enter your home.

In addition, below are a few more things to consider when buying or using a space heater.

  • Look for newer models that have the up-to-date safety features. They should have the Underwriter’s Laboratory (UL) label.
  • Only buy what you need. You don’t need a huge heater for a small room. Look for a sizing chart on the box.
  • Heaters should be put on level surfaces where they won’t be in anyone’s way. Always keep pets and children far away.
  • Kerosene heaters are not recommended in your home, and in some communities, may even be illegal to use.
  • Remember to install or check your smoke alarms and carbon monoxide alarms!

Thermostat Use & Savings

It’s about that time of year when many of us see a big increase in our electric bills… all because we’re trying to stay warm. Using your thermostat wisely though, can help you stay comfortable while also saving money.

A simple tip—lower the temperature just by a degree or two. Each drop of one degree for an 8 to 10 hour time period equals a drop of your energy bill of about one percent. Over time you may easily get used to a drop of 3 or 4 degrees.

Skip the fan “on” setting. If you always run the fan motor, this can increase your bill by $20 or more each month. Instead, the “auto” setting only runs the fan when the system is running. The “on” setting can be used once in awhile if you find some spots in your home are cooler than others.

Consider a programmable thermostat. You can adjust the times that the heating is on with a pre-set schedule. You’ll want to consider the household’s daily routines and when people will not be home. You can also manually override it.

Take a look at the location of your thermostat in your home. It should not be close to drafts, direct sunlight, doorways, windows and furniture.

When going on vacation for a long period of time you can lower the temperature but make sure to keep it above about 55 degrees to prevent issues such as pipes freezing if the temperature outside drops quickly.

Common Heating Mistakes

Want to help prevent your heating bills from flying sky high this winter? While weatherstripping your windows and regularly inspecting and tuning your heating system are great ways to make sure the heat in your home is used efficiently, there are more things you can do to help. You may have already thought of some of these ideas while others may come as a surprise to you because you’ve been doing the opposite all of these years! Below is some advice to help you make sure you’re doing all you can to maximize the work your heating system is doing for you.

Curtains aren’t just decoration or a way to keep the sun out of your eyes. In fact, they can actually help keep the cold out, or let the heat in, when a warmer afternoon comes along. Draperies can reduce heat loss from a warm room up to 10%. During the cold months make sure to close them at night. Hang them as close to windows as you can and let them fall onto a windowsill or floor. Consider hanging several together to create a tighter air space.

Leave all of the vents open. Many people believe that closing vents in one area of the house that isn’t used as much would help send the heat to the more commonly used areas. Well, it doesn’t work that way. All of the vents need to be open for the HVAC system to work properly.

Don’t blast the thermostat to quickly warm up the house. On a day when the temperature changes drastically, turning up the heat very high suddenly will not heat the house up faster and can increase your bill.

Don’t keep the heat low at certain times of day. Some people like to sleep when it is cooler while others like to turn down the thermostat when they go to work because they think it will save money. This can actually backfire because the system then needs to work even harder to adjust back to a higher temperature when you decide you want it to be warmer.
