EATING
Your new Green Mountain Insert 70 wood insert 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 insert. Whole house zone heating
works best when the insert 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 insert 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 insert 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 insert, the size, layout and age of
your home and your climate zone. Three-season
vacation homes can usually be heated with smaller
inserts than houses that are heated all winter.
