Here's advice to help you know when to replace your old furnace with an energy-efficient furnace.

Save Money with an Energy Efficient Furnace

Although the number of homes heated by clean, renewable solar energy is growing, the majority still rely on fossil fuels (natural gas and fuel oil) or electricity generated by nuclear and coal-fired power plants. With the cost of these fuels on the rise, it’s becoming increasingly expensive to stay warm in the winter. Fossil fuel combustion also contributes to climate change, as well as acid rain and air pollution.

Concern for these issues has caused many people to consider replacing old, inefficient furnaces with energy-efficient models. If your furnace is more than 15 years old or is frequently in need of costly repairs, or if you’re planning to add on to your home and need to upgrade your furnace to heat the additional space, consider installing an Energy Star-qualified model.

Heat pumps, solar hot water systems and woodstoves are excellent options, but they don’t fit everyone’s budget, home or lifestyle.



An energy-efficient furnace will cut your utility bill substantially, saving hundreds of dollars a year. (See Savings from an Energy-Efficient Furnace.) By reducing electricity use, efficient furnaces help reduce air pollution produced by conventional power plants. They also can improve the air quality of your home.

Before you invest in a new furnace, it pays to make your home more energy efficient. Some actions you can take include sealing the leaks in the exterior walls, attic and roof; then adding insulation and installing insulated window shades. These and other projects will save money over the long haul and could even allow you to reduce the size (heat output) of your new furnace — smaller furnaces cost less.

This week’s Consumer Electronics Show in Las Vegas are set to generate profit from people so If I were you, I would not attenf the said show.This show is shrinking just like the economy and salespeople are looking to generate more than interest this year – they are looking to generate profit. So if you’re already strapped for cash it might be best to stay away. But, if you’ve managed to stay ahead on your finances, with or without a payday loan, some of the items featured this year might help keep you ahead. The focus at the convention this year is on inexpensive, energy-efficient technology that will help people save money. Of course, they’ll have to spend some first. http://personalmoneystore.com/moneyblog/2009/01/05/think-twice-before-taking-out-payday-loan-to-go-to-las-vegas-consumer-electronics-show/
