Programmable Thermostats

You can save as much as 10% a year on your heating and cooling bills by simply turning your thermostat back 10 to 15 for 8 hours.  You can do this automatically without sacrificing comfort by installing an automatic setback or programmable thermostat.

Using a programmable thermostat, you can adjust the times you turn on the heating or air-conditioning according to a pre-set schedule.  As a result, you don't operate the equipment as much when you are asleep or when the house or part of the house is not occupied.  (These thermostats are not meant to be used with heat pumps.)  Programmable thermostats can store and repeat multiple daily settings (six or more temperature settings a day) that you can manually override without affecting the rest of the daily or weekly program.

Ducts

One of the most important systems in your home, though it's hidden beneath your feet and over your head, may be wasting a lot of your energy dollars.  Your home's duct system, a branching network of tubes in the walls, floors, and ceilings, carries the air from your home's furnace and central air conditioner to each room.  Ducts are made of sheet metal, fiber glass, or other materials.

Unfortunately, many duct systems are poorly insulated or not insulated properly.  Ducts that leak heated air into unheated spaces can add hundreds of dollars a year to your heating and cooling bills.  Insulating ducts that are in unconditioned spaces is usually very cost effective.  If you are buying a new duct system, consider one that comes with insulation already installed.

Sealing your ducts to prevent leaks is even more important if the ducts are located in an unconditioned area such as an attic or vented crawl space.  If the supply ducts are leaking, heated or cooled air can be forced out unsealed joints and lost.  In addition, unconditioned air can also be drawn into return ducts through unsealed joints.  In the summer, hot attic air can be drawn in, increasing the load on the air conditioner.  In the winter, your furnace will have to work longer to keep your house comfortable.  Either way, your energy losses cost you money.

Although minor duct repairs are easy to accomplish, ducts in unconditioned spaces should be sealed and insulated by qualified professionals using the appropriate sealing materials.  Here are a few simple tips to help with minor duct repairs.

*Note:  Water pipes and drains in unconditioned spaces could freeze and burst in the space if the heat ducts are fully insulated, because there would be no heat source to prevent the space from freezing in cold weather.  However, using an electric heating tape wrap on the pipes can prevent this.

Heat Pumps

If you use electricity to heat your home, consider installing an energy-efficient heat pump system.  Heat pumps are the most efficient form of electric heating in moderate climates, providing three times more heating and cooling than the equivalent amount of energy they consume in electricity.  There are three types of heat pumps:  air-to-air, water source, and ground source.  They collect heat from the air, water, or ground outside your home and concentrate it for use inside.  Heat pumps do double duty as a central air conditioner.  They can also cool your home by collecting the heat inside your house and effectively pumping it outside.  A heat pump can trim the amount of electricity you use for heating as much as 30% to 40%.

Solar Heating

Using the sun to heat your home through passive solar design can be both environmentally friendly and cost effective.  In many cases, you can cut your heating costs by more than 50% compared to the cost of heating the same house that does not include passive solar design.  Passive solar design techniques include placing larger, insulated windows on south-facing walls and locating thermal mass, such as a concrete slab floor or a heat-absorbing wall, close to the windows.  However, a passive solar house requires careful design, best done by an architect for new construction or major remodeling.

Fireplaces

When you cozy up next to a crackling fire on a cold winter day, you probably don't realize that your fireplace is one of the most inefficient heat sources you can possibly use.  It literally sends your energy dollars right up the chimney along with volumes of warm air.  A roaring fire can exhaust as much as 24,000 cubic feet of air per hour to the outside, which must be replaced by cold air coming into the house from the outside.  Your heating system must warm up this air, which is then exhausted through your chimney.  If you use your conventional fireplace while your central heating system is on, these tips can help reduce energy losses.
