ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU
Your new WFP-75 wood fireplace is a space heater, which means it is intended to heat the area it is installed
in as well as spaces that connect to that area, although to a lower temperature. This is called zone heating
and it is an increasingly popular way to heat homes or spaces within homes.
Zone heating can be used to supplement another heating system by heating a particular space within a
home, such as a basement family room or an addition that lacks another heat source.
Houses of moderate size and relatively new construction can be heated with a properly sized and located
wood fireplace. Whole house zone heating works best when the fireplace is located in the part of the house
where the family spends most of its time. This is normally the main living area where the kitchen, dining and
living rooms are located. By locating the fireplace in this area, you will get the maximum benefit of the heat it
produces and will achieve the highest possible heating efficiency and comfort. The space where you spend
most of your time will be warmest, while bedrooms and basement (if there is one) will stay cooler. In this
way, you will burn less wood than with other forms of heating.
Although the fireplace may be able to heat the main living areas of your house to an adequate temperature,
we strongly recommend that you also have a conventional oil, gas or electric heating system to provide
backup heating.
Your success with zone heating will depend on several factors, including the correct sizing and location of
the fireplace, the size, layout and age of your home and your climate zone. Three-season vacation homes
can usually be heated with smaller fireplaces than houses that are heated all winter.
2.5 THE BENEFITS OF LOW EMISSIONS AND HIGH EFFICIENCY
The low smoke emissions produced by the special features inside the WFP-75 firebox mean that your
household will release up to 90 percent less smoke into the outside environment than if you used an older
conventional stove. But there is more to the emission control technologies than protecting the environment.
The smoke released from wood when it is heated contains about half of the energy content of the fuel. By
burning the wood completely, your fireplace releases all the heat energy from the wood instead of wasting it
as smoke up the chimney. Also, the features inside the firebox allow you to reduce the air supply to control
heat output, while maintaining clean and efficient flaming combustion, which boosts the efficient delivery of
heat to your home.
The emission control and advanced combustion features of your fireplace can only work properly if your fuel
is in the correct moisture content range of 15% to 20%. See
Section 3: Fuel
of this manual for suggestions
on preparing fuel wood and judging its moisture.
2.6 THE HEARTHSTONE COMMITMENT TO YOU AND THE ENVIRONMENT
The HEARTHSTONE team is committed to protecting the environment, so we do everything we can to use
only materials in our products that will have no lasting negative impact on the environment.
2.6.1 WHAT IS YOUR NEW FIREPLACE MADE OF?
The body of your fireplace, which is most of its weight, is carbon steel. Should it ever become necessary
many years in the future, almost the entire fireplace can be recycled into new products, thus eliminating
the need to mine new materials.
The paint coating on your fireplace is very thin. Its VOC content (Volatile Organic Compounds) is very low.
VOCs can be responsible for smog, so all the paint used during the manufacturing process meets the
latest air quality requirements regarding VOC reduction or elimination.
The air tubes are stainless steel, which can also be recycled.
