Have your system serviced by a qualified contractor every two to three years. If the unit is 10 years or older, consider having it serviced yearly.

- A whole house fan can reduce air conditioning costs. It is a high velocity fan that is usually installed in the ceiling of a central hallway within a home. Outside air is drawn in through open windows. The air is then exhausted through the attic.
- Older windows are usually not very energy efficient. You might decide to replace older windows or you can use these ideas to reduce air conditioning and heating loss.
- If you frequently burn firewood, consider the installation of a fireplace insert. This can provide greater heating efficiency. Use only well-aged firewood, which burns hotter and cleaner.
Average Hot water use
Clothes washing 32
Automataic Dishwashing 4-10
Preparing food 5
Hand dishwashing 4
The average dishwasher uses 6-8 gallons of water per cycle; the average Energy Star-rated dishwasher uses 4 gallons per cycle.
Can hand washing be as efficient as dishwashing?
The average faucet flows at 2 gallons per minute.
(Mine with an aerator or using the spray uses 1.5 gal per minute.)
A dishwasher can handle an 8 - 10 place settings.
That's 48 pieces of dishware - 6 pieces (including silverware) per setting
and 6 serving dishes for 54 pieces.
To do it in 3 minutes (6 gallons) you'd have 3.3 seconds per piece.
Most dishwasher manuals say you do not need to pre-rinse.
If you use 2.2 seconds/per piece that's 3 gallons of water.
Washing by hand is almost as good as using a new machine, provided that the hand-washer uses efficient techniques. Installing an aerator in your faucet can save 3 to 4 gallons for every minute that your tap is running. Scraping food off, soaking dishes in a basin of soapy water before getting started, and not letting the water run while you wash every dish will help you save water and energy. And it's best to have two basins to work in--one filled with hot, soapy water, the other with warm water for a rinse.
