Just a couple of decades ago, about 20 cents out of every heating dollar went straight up the chimney, even with the most efficient furnaces available at the time. Today, we have many options available for superior comfort, energy efficiency, and safety. Here is an overview of three technologies that deliver energy savings and improved comfort.
High-efficiency heating means more money in your pocket
When a furnace is manufactured, it is assigned an Annual Fuel Utilization Efficiency Rating (AFUE). This rating is expressed as a percentage, and it represents the amount of usable energy (heat) that is delivered from each unit of fuel. A gas furnace is rated with an AFUE of 60%, this means that for every dollar you spend on gas, 40 cents goes right up the chimney.
Two-stage heating delivers just the right amount of heat
On moderately cold days, a two-stage gas valve has a first-stage setting allowing only parts of the gas flow from the pipes to enter the furnace. This means your furnace will take a little longer to reach the temperature set on your thermostat. In this way, the furnace delivers heat gently, with fewer drafts. On colder days, the furnace uses the second stage setting to reach the optimal temperature for comfort. Most people find two-stage heating to be more comfortable than standard heating.
Variables-speed furnaces help save electricity
Variable-speed blower motor (fan) technology delivers warm air continuously over a longer heating cycle. This produces unmatched comfort with almost silent operation. An even better benefit is the lower operating costs associated. If you have an air cleaner or ventilation, then you must run your furnace fan continuously. A standard furnace consumes anywhere from four to seven times as much electricity as a variable-speed furnace.
If you have an older furnace, then you may benefit from the energy savings and improved comfort provided by a furnace with updated technology. If you are considering upgrading your furnace or have questions regarding your options, please contact us.
