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 www.energystar.gov.

5. Combustion Systems & Garage Isolation

5.3  Fireplaces and fuel Burning Appliances located in conditioned spaces shall meet the following efficiency or emissions standards and restrictions: 
Masonry fireplaces are not permitted, with the exception of masonry heaters, as defined by ASTM E1602, and the IBC, 2112.1.

Factory-build, wood-burning fireplaces shall meet the certification requirements of UL 127, and meet the emission limits in EPA 40 CFR Part 60.

Natural gas and propane fireplaces shall be power vented or direct-vented, as defined by NFPA 54, 3.3.108, have a permanently fixed glass front or gasketed door, and comply with ANSI Z21.88/CSA 2.33.

Wood stove and fireplace inserts as defined in Section 3.8 of UL 1482, shall meet the certification requirements of that standard, and shall meet emission requirements of EPA 40 CFR Part 60 and WAX 163-433-100(3).
 
Pellet stoves shall meet the requirements of the ASTM E1509.

Decorative gas logas as defined in K.1.11 of NFPA 54 (National Fuel Gas code) are not permitted.

Un-vented combustion appliances are not permitted, with the exception of kitchen-type cooking devices with exhaust ventilation meeting ASHRAE 62.2 section 5.

5.4 Fireplaces and Fuel Burning Appliances located in conditioned spaces shall meet the following additional design and installation requirements:
Vented to the outdoors; AND
Adequate combustion and ventilation air shall be provided minimizing the potential for spillage or “back-drafting”, either by complying with ASHRAE 62.2 section 6.4 or equivalent design requirements, or by conducting a Worse Case Depressurization Combustion Air Zone (CAZ) Test according to an established protocol.
