When people think of hybrid technology, they generally think of cars that run on both electricity and gas. This is the most efficient way to achieve maximum miles per gallon and utilize the best of both worlds in energy usage. This same technology can be applied to the heating and cooling system in your home and you can use the least expensive energy to heat your home at any given time.
The hybrid system uses an electric heating system to heat your home in the temperature range that is most cost effective for electricity rates, which is down to 32 degrees. Below this temperature, it becomes less expensive to heat with natural gas. A high efficiency induced-draft furnace takes over to provide heat in the colder weather and this hybrid system switches back and forth from gas to electric heat, utilizing an outdoor temperature sensor that registers the information to a device called a dual fuel interface thermostat. This thermostat determines which energy source to use and it switches back and forth automatically using preprogrammed information about the cost of gas and electric in your service area. This information can be updated as the cost of both gas and electricity fluctuate to make sure you are using the most efficient, least expensive energy source available at the time. Another name for the hybrid system is dual fuel and some utility companies pay an upfront rebate on the unit.
Most people are unaware that electricity rates are much lower in the winter than in the summer. This is due to the simple economic concept of supply and demand. In the summer, there is high demand for electricity to run all the air conditioners needed to cool homes and businesses. The utility companies have to expand their electricity generating capabilities to meet peak demand in the summer, but that leaves them with extra capacity during the winter. To get rid of the extra electricity in the winter, they charge less for it and that means a lower cost source of heat for you. The gas company also charges different amounts for gas due to demand, but demand is always highest in the cold of winter. A lot of people prefer the cooler discharge temperature of a hybrid as it does not dry you out as bad as a gas furnace and the need for a humidifier is lessened. In the summer, a hybrid system cools exactly the same as a regular air conditioner, but in the winter it can save hundreds of dollars in expense in gas consumption.
Hybrid technology has been used in the automotive industry for years and it has been incorporated in the home heating and cooling systems for over twenty five years. The extreme cost of energy has now renewed an interest in the savings afforded to those who “hedge” against the unstable rising cost of utilities. Think about replacing your old worn out system with a new hybrid system this season before the hot summer months arrive.
