Zone Heating: An Efficient Way to Heat a Home

A central furnace cycles on and off several times an hour and heats your entire house – even unoccupied rooms – wasting money.  Using supplemental hearth appliances to heat only the rooms a family uses most allows them to turn down the thermostat for the central furnace, decreasing fuel bills.

“Zone heating” puts the heat where its needed, not only adding to a home’s comfort and ambiance, but also reducing household fuel consumption, conserving energy, and saving money.   Studies indicate that zone heating solutions can provide energy savings of 20-40 percent.*

Saving Energy:  An Easy to Use Fuel Calculator

HPBA has developed an easy to use fuel calculator that provides the projected cost of the hearth product’s use.

Energy Star

When selecting an appliance or guiding customers to a hearth product, consider an Energy Star appliance.  The following is excerpted from the Energy Star Indoor Air Package Specification, Version 2, dated April 19, 2007.  For complete information on Energy Star products and guidelines, visit
