GENERAL DESCRIPTION
WHAT DOES THIS GUIDE SHOW?
This operational cost savings guide has been prepared to show theoretical
cost savings for Bard dual fuel “add-on” heat pumps when used with either
existing or new furnaces. It covers add-on applications for electric, oil,
propane gas and natural gas type forced air furnaces. It Includes both air
source heat pumps and ground water source heat pumps at many combinations of
gas, oil and electrical rates. It enables the user not only to make a
theoretical operating cost comparison at today's fuel costs but also at
future estimated higher energy costs.
It Is Important to understand that this Is a theoretical comparison between
fuels. Actual operation costs can vary depending on many difficult to
predict variables such as the actual design heating or cooling load, air
Infiltration, and wind effects, solar effect, efficiency of existing furnace,
severity of weather for a given heating or cooling season and also individual
usage pattern.
X
SPECIAL FEATURE—FUEL SAVER MODULE
These estimates utilize the Bard Fuel Saver Module which permit the heat pump
to operate below the balance point to maximize the energy savings. For each
application an analysis should be made to determine the economic balance
point which Is the outdoor temperature at which It becomes more cost
effective to shut the heat pump down with an outdoor thermostat. This
temperature varies with each combination of fuel cost and furnace and heat
pump efficiency level. Refer to tables included in the instructions with the
Fuel Saver Module.
FURNACE EFFICIENCY
For purposes of these cost estimates, furnace efficiency levels of 100% AFUE
for electric, 78% AFUE for natural and propane gas and 78% AFUE for oil was
chosen. We recognize that any variation in efficiency from these values will
change the operating cost somewhat. These values were chosen to best
represent typical efficiency levels of most equipment in the field today.

You now have located the page or pages that will help you determine annual

operating cost. See example—Figure 1.
A. Locate the closest structure loss in Btuh column on left side of
page (step 1).
EXAMPLE: 70,000 Btuh Heat Loss
B. Locate the heating cost per unit at top of page (step 3).
EXAMPLE: $1.40 per gallon fuel oil
C. Now read down the fuel cost column until directly across from the
structure heat loss in Btuh. This will be the theoretical annual
heating cost using only the furnace.
EXAMPLE: 70,000 Btuh heat loss 0 $1.40 per gallon fuel oil,
the annual cost will be $1,912.
D. Next locate the electric cost $/KW under Heat Loss Btuh for
structure (step 3).
EXAMPLE; $.06 KW rate
E. Now once again read down the fuel cost column until directly across
from electric cost $/KW. You now have located the annual heating
cost for the house using an add-on heat pump with the furnace.
EXAMPLE: 70,000 Btuh structure heat loss, with $.06 KW cost and
$1.40 per gallon fuel oil. The annual cost using a
36UHPQA Bard heat pump with the oil furnace would be
$1,613 for an annual savings of $299 ($1,912 minus $1,613),
Now repeat steps 8 through 9 for each type fuel and/or heat pump
selected. This will enable you to select the best combination of
furnace and heat pump to use for a structure.

10. The balance point (the outdoor temperature at which the heat pump Is
running 100% of the time and just meeting structure heat loss
requirements) is located on right side of page.
EXAMPLE: For a structure with a 70,000 Btuh with a 36UHPQA heat pump has
a balance point of 31®F. Below this theoretical balance
point, the heating load is automatically transferred between the
heat pump and the furnace by the wall thermostat to maintain the
desired temperature. This is accomplished with the Fuel Saver
Module.

NOTE: The accuracy of the "Dual Fuel-Add-On Heat Pump Guide to
Energy Cost Savings," is directly affected by how accurately you
estimate the structure's heat loss and heat gain in step 1.
Because of uncontrollable variables, Bard Manufacturing Company is
not responsible for any variation In actual operating costs from
these theoretical estimates.
