Home Heating Costs
- How to keep your heating costs down this
winter
-
- Your furnace uses more energy than any other appliance
in your house. Consequently, the cost of heating your house
accounts for the biggest part of your energy bill - an overwhelming
60%. Even if you're using natural gas, which saves 40% to
60% over using electricity, oil or propane, winter can still
hit you in the pocket book. If you're in the market for
a new furnace, upgrading to a more efficient model could
be the most effective way for you to improve your home's
energy efficiency and save money on energy costs. And even
if you're not ready to buy a new furnace, tuning up your
existing one should help keep your winter heating bills
down.
-
- What you can do to keep your existing
furnace operating at its peak this winter.
- * Change or clean furnace filters regularly.
- * Inspect fan belts while you change the filters.
Replace if cracked or worn (turn off electricity first!)
- * Insulate ducts in unheated areas with fireproof
insulate. Seal cracks and joints with duct tape.
- * Vacuum heat and return air ducts regularly.
- * Close off heat registers and doors to unused rooms.
Tip: Do not shut more than one-third of total heat registers.
This forces furnace to cycle more frequently.
- * Adjust room registers (open them and ensure they
are clear of rugs or furniture) in the rooms you use.
- * Vacuum baseboards if you have a radiant baseboard
system.
- * Consider a programmable thermostat. You'll save
energy at night and while you're away, and return home
to a warm house. While you can do a good deal of furnace
maintenance by yourself, some things should be left
to the experts. A qualified technician should service
your furnace according to the manufacturer's instructions.
-
- What only a qualified technician should
do.
- 1. Tune-up the furnace. A qualified technician can
clean and adjust the pilot burner, main burner, fan
or blower, and test and tune your furnace for maximum
combustion efficiency.
- 2. Check chimney and appliance vent system.
- 3. Do a full safety inspection.
Tip: Make sure a one-year parts and labour warranty
is included on any work done.
-
- What if you need a new furnace?
-
- At a certain point it makes more sense to replace your
old furnace than to service it again. Chances are you'll
know when you reach that point. If you're presently at this
point, it is helpful to know what is currently available
in natural gas furnaces. Natural gas furnaces are available
in mid- and high-efficiency models - either of which will
heat your home at a fraction of the cost of electricity
or oil. By law, the minimum allowable furnace efficiency
is 78%, the starting point for mid-efficiency models.
-
- Mid_Efficiency Furnaces
- Mid-efficiency furnaces are considered today's average
furnace. They have electronic ignitions, eliminating the
need for a continuous pilot. They also have induced draft
fans which provide better control of combustion air, eliminating
the need for a draft hood. You'll find mid-efficiency furnaces
from 78% to 83% efficient.
-
- High-Efficiency (condensing) Furnaces
-
- High-efficiency furnaces range from 90% -97% efficient.
They have an additional heat exchanger to recover even more
heat from the flue gases. Therefore, they use about 30%
less natural gas than a similarly-sized standard natural
gas furnace while providing the same heat. And because high-efficiency
furnaces can be vented through an exterior wall, they give
you more flexibility in installation.
-
- High-efficiency furnaces generally cost more to purchase
than mid-efficiency models, but the higher price can easily
be offset by long-term fuel cost savings and possible savings
from eliminating the need to construct a chimney in a new
home.
-
- How to select the right furnace for
your home.
- Before you select a new furnace, consider the following
points:
- Furnace Sizing:
To give you the most comfort and economy, your new furnace
must be the correct size to meet the heating needs in
your home. Factors such as the size, construction and
heat loss of your home, local winter temperatures, ductwork
design, filter system, venting and space limitations
should all be taken into consideration. Furnace sizing
should be determined only after your heating contractor
has completed a "design heat loss" calculation for your
home.
- Home Improvements:
If you're upgrading your home's windows, doors, weather-stripping
or insulation, it is best to do it before you choose
a new furnace. The resulting reduction in heat loss
may decrease the size of the furnace you need and allow
you to purchase a smaller, less expensive model for
your home.
- Obtaining Quotes:
Purchase and installation prices may vary considerably
- always compare the products of a variety of manufacturers
and get several installation price quotations. Make
sure you're comparing similar products.
- Installation:
A well-designed furnace must be properly installed to
achieve its maximum efficiency. After your furnace installation
is complete, ask your contractor to certify that all
tests specified in the manufacturer's instructions have
been carried out. Be sure to read and follow the manufacturer's
directions for your furnace's operation and maintenance.
