Household heating/cooling takes up some 35% - 45% of residential energy use, you can achieve plenty of saving on energy when adopting a 'dual fuel' hybrid system; using heat pump for less punishing weather and stick with a gas furnace for really cold months. It is a proven technology and you can now alternate very warm air with very hot air through heat pump and furnace respectively.
Energy used for `residential heating has been on the rise lately. According to a 2005 survey, the average American household burned somewhere around $1200-$1500 for heating alone. It makes sense that we look into ways to bring down this amount. One of the necessary measures is to give your furnace a proper tune up in order to make it run more efficiently.
Residential heating systems are made up of three components:
Do you have a drafty window? Do you find yourself getting busy with all sorts of tricks with the windows just to keep your home warm or cool? Do you see visible cracks or gaps? Are your problems with the windows and/or doors related to the usual wear and tear or are these all signs of improper insulation? If any of the questions above are troubling you, there is a strong likelihood that these problems are costing you some 30% heat loss in your household.
Consumer electronics make up close to 8% of residential energy costs. Amazingly, some appliances such as stereos, cell phone charges, DVD players, computers and televisions can eat up as much as a quarter of their power requirement even when they are off (or on standby) mode. Up to 5% of the power is often required just to display that nice little clock.
