Impact of shifting certain appliances
- Electric heat. Most heating needs are at night when it is coldest. Portable space heaters should be used as little as possible during on-peak hours.
- Electric water heater. You can install a timer that limits water heating to off-peak hours. Most tanks store enough hot water for on-peak use.
- Electrically heated spa, hot tub or pool. You can install a timer that limits hot tub, spa or pool heating to off-peak hours.
- Other large users of electricity. You can shift electric welding equipment, commercial painting equipment, high-intensity industrial lighting and other large electricity users to off-peak hours.
- Central air conditioner. Most air conditioning is used on-peak (high-cost times). Limit use during on-peak hours and cool during off-peak hours.
- Dehumidifier, outdoor lights, pumps. Install plug-in or hard-wired timers on outdoor lights, pumps, dehumidifiers and other large appliances.
- Electric clothes dryer. Do laundry during off-peak hours.
- Electric range. Bake and cook during off-peak hours.
- Household lighting
- TV, computer, electronics
- Refrigerators and freezers
- Small appliances
- Clothes washer (unless you have an electric water heater)
- Gas heat
- Gas water heater
- Microwave oven
Note: Appliances that consume the same amount of electricity day or night cost slightly less on Time-of-Use.
How to tell if you have a gas or electric water heater
Gas Water Heater
Gas water heaters have a large exhaust pipe (metal or plastic) on top of the unit going from the heater to a chimney or out the side of the house.
Electric Water Heater
Electric water heaters do not have an exhaust pipe — just small water pipes running into the top of the unit.
