Energy Efficient Water Heater and Furnace
Water heating can be the second largest residential energy user according to the Department of Energy - and the largest in some temperate climates. If you heat with gas, water heating can soak up 40% of your energy bill.
In most homes, showers use-and waste-the most hot water. Even one 5 minute shower can take 25 gallons of water. New efficient low-flow shower heads can cut your water use in half saving the average household 14,000 gallons a year without sacrificing comfort.
Switching from electric water heating to gas can save you up to 75% of your water heating bill.
The cost of installing a low-flow shower head is paid back in energy savings during the first month of use.
For every extra minute you spend in the shower, you put lb. of carbon dioxide into the air.
Electric versus Gas Heating
Power plants turn heat energy generate by burning fuels into electromagnetic energy that flows through wires. But only about 35% of the heat energy can be transformed into electricity. This energy source is most efficiently and wisely used to power motors generate light, and for small spot heating applications (toasters or irons for example)
Electric heat, such as that generated by the burner of an electric range, is very inefficient compared to gas heat which is burned at the point where heat is needed. Heating with electricity typically costs over twice as much as heating with gas and has greater environmental impact.
Giving your gas heating system a simple tune up will increase its efficiency by 5% saving an average of 8,000 cubic feet of gas annually
Electric heating is always more expensive and has greater environmental impact than gas heating.
America's heating systems emit over a billion tons of carbon dioxide into the atmosphere every year as well as about 12% of the nation's sulfur dioxides and nitrous oxides.
