High-efficiency furnaces consume at least 30% less fuel than older model furnaces. These heaters typically have a lower BTU rating for heat output. Some newer models offer an annual fuel utilization efficiency rating of 97%. Cleaning and repairing a high-efficiency furnace on a regular basis will keep the unit working correctly. This routine maintenance will reduce the furnace’s consumption of fuel and prevent carbon monoxide from entering the home. The home should be adequately insulated to make it as energy efficient as possible before installing a new furnace heating system.
The U.S. Department of Energy says 56% of the energy used in an average home comes from the heating and cooling system, 30% of which is from the heating component. High-efficiency furnaces produce heat more steadily. This HVAC systems are better at controlling the amount of air mixed with gas and vary the blower motor’s speed depending on what the house needs. These variable speed blowers are less noisy and do not drastically change the house’s temperature. Sealed combustion, the process of bringing all the combustion air from outside and mixing with fuel at a controlled rate, maximizes fuel heat.
Look for models that offer features such as a modulating burner that will continuously adjust heating levels in small doses to match the home’s comfort level. Many of these furnaces are tailored to match the home’s regional location. People who live in Philadelphia will have different heating needs versus people who live in Phoenix. Many high-efficiency furnaces are self-monitored, making the furnace’s set up and maintenance faster and easier.
An electrostatic filter can reduce the amount of dust that goes through the furnace. This filtering system can be an enormous relief to people with lung problems, such as asthma. High-efficiency heating systems do not have a pilot light instead they have either intermittent, direct spark ignition or hot surface ignition.
These high-efficiency systems are more expensive upfront than standard HVAC systems. But these units will save the customer’s money, in the long run, thanks to lower fuel costs over the furnace’s lifetime. An energy efficient systems can save the customer $40 for every $100 spent on fuel. High-efficiency gas and electric furnaces can cost $4,400 to $4,600, and Oil-based ones can cost about $6,000. Always choose a system that comes with a good warranty.
