Because air source heat pumps move heat rather than generating it, they are often 2-3 times more efficient than electric baseboard heating systems and are much cheaper to operate than fuel-oil and propane systems. They are also more efficient than other air-conditioning systems, providing additional savings during the summer.
Calculation in Completed Actions is actual savings which is updated monthly.
If appropriate, use laptop computers and inkjet printers they consume 90 percent less energy than standard desktop computers.
Ground water can enter basements and crawlspaces, causing damage to the foundation and floor material, and promoting mold growth. Check for signs of seepage and leakage, and take appropriate action, such as installing sump pumps, etc.
Using the dishwasher with only full (or near full) loads of dishes saves substantial amounts of washing energy, water heating energy and water.
Some dishwashers do not make efficient use of electricity and hot water. This is especially true of older models, and in homes with large numbers of people and dishwashing.
Certain glass doors (particularly older, metal-frame, single pane ones) transmit a lot of warmth out of your home in the winter, and a lot of coolness in the summer. This can be prevented by replacing them with multipaned and insulated frame glass doors.
If you do not clean your humidifier regularly it will have to work harder to maintain your preferred humidity setting.
In many circumstances, a humidity setting of 20% is sufficient; consult your home equipment advisors and physician to determine the minimum needed humidity level.
Your pool will naturally lose some water to evaporation and splash-out. Your pool may also gain water from rainfall. Pools should be watertight, but sealants deteriorate and parts of your pool shift and crack. Pools can leak through any of these cracks or through dislodged fittings.
Certain doors (particularly older, metal-frame, hollow or thin ones) transmit a lot of warmth out of your home in the winter, and a lot of coolness in the summer. This can be prevented by replacing them with insulated doors.
