To make your home or office energy efficient without investing too much, you’d better follow these recommendations made by the US Department of Energy.
You can save money on your heating and cooling bills by simply resetting your thermostat when you are asleep or away from home. You can do this automatically without sacrificing comfort by installing an automatic setback or programmable thermostat.
You save energy in the winter by setting the thermostat to 68°F while you’re awake and setting it lower while you’re asleep or away from home.
In the summer, you can follow the same strategy with central air conditioning by keeping your house warmer than normal when you are away, and setting the thermostat to 78°F (26°C) only when you are at home and need cooling.
Ducts that leak heated air into unheated spaces can add hundreds of dollars a year to your heating and cooling bills, but you can reduce that loss by sealing and insulating your ducts. Insulating ducts in unconditioned spaces is usually very cost-effective.
- Set your programmable thermostat as high as is comfortable in the summer and raise the setpoint when you’re sleeping or away from home.
- Clean or replace filters on air conditioners once a month or as recommended.
- Turn off kitchen, bath, and other exhaust fans within 20 minutes after you have cooked or bathed; when replacing exhaust fans, consider installing high-efficiency, low-noise models.
- During summer, keep the window coverings closed during the day to block the sun’s heat.
- Select energy-efficient products when you buy new cooling equipment.
- Set your programmable thermostat as low as is comfortable in the winter and lower the setpoint when you’re sleeping or away from home.
- Clean or replace filters on furnaces once a month or as recommended.
- Clean warm-air registers, baseboard heaters, and radiators as needed; make sure they are not blocked by furniture, carpeting, or drapes.
- Eliminate trapped air from hot-water radiators once or twice a season; if unsure about how to perform this task, contact a professional.
- Place heat-resistant radiator reflectors between exterior walls and the radiators.
- Turn off kitchen, bath, and other exhaust fans within 20 minutes after you are done cooking or bathing; when replacing exhaust fans, consider installing high-efficiency, low-noise models.
- During winter, keep the draperies and shades on your south-facing windows open during the day to allow the sunlight to enter your home and closed at night to reduce the chill you may feel from cold windows.
- Select energy-efficient products when you buy new heating equipment.
Water heating accounts for about 18% of your home’s energy use. Reducing your hot water use, employing energy-saving strategies, and choosing an energy-efficient water heater for your home pool can help you reduce your monthly water heating bills.
Tankless Water Heaters
Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don’t produce the standby energy losses associated with storage water heaters, which can save you money.
Solar water heaters — also called solar domestic hot water systems — can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use — sunshine — is free.
Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which do not.
Reduce Hot Water Use
You can lower your water heating costs by using and wasting less hot water in your home. Water heating is the second-largest energy expense in your home. It typically accounts for about 18% of your utility bill after heating and cooling. To conserve hot water, you can fix leaks, install low-flow fixtures, and purchase an energy-efficient dishwasher and clothes washer.
Lower Water Heater Temperature
Some manufacturers set water heater thermostats at 140ºF, most households usually only require them to be set at 120ºF, which also slows mineral buildup and corrosion in your water heater and pipes. Water heated at 140ºF also poses a safety hazard—scalding.
