ed Water Heaters. DOE used average equipment prices, installation costs, and energy use values from the 2010 Water 

re.energy.gov/buildings/appliance_standards/residential/heating_products_fr.html). Because the average total installed 

ge water heater (ESWH) ($1,005) is higher than the average cost of relining ($848) for a new gas storage water heater 

n the GSWH is at the end of its useful life. The average installed cost of a GSWH ($2019) includes the total installed cost of 

ost of relining($848). The total installed cost of switching to an ESWH ($1005) includes both the total installed cost of the 

 adding electrical service ($295). On average, the consumer will see a total installed cost savings of ($1,014) when 

fset by the operating cost difference between gas and electric water heater. The operating cost is determined by 

or both ESWH and GSWH and multiplying the use by the appropriate energy prices. The average energy use for a ESWH is 

ption of 44 gallons/day and a baseline efficiency of 0.95 EF; for GSWH the same average water consumption of 44 

efficiency of 0.62 EF (the energy efficiency standard in 2016). This results in 2,678 kWh/year for ESWH compared to 15.4

Implementation of APGA Installation Costs

AGA Cost Data Range of 

Est. Cost (2005$)

Reline existing chimney or resize vent to accommodate the remaining 

appliance (code requirement for proper vent sizing) $600 - $1,000

Install drain pan for condensate from condensing furnace (code 

requirement to avoid structural damage) $150 - $250

Install freeze protection for condensate line to ensure reliability of 

disposal (for installation outside of conditioned space) $200

Perform structural modifications (including boring holes in Interior 

walls, floors, exterior walls for vents and new vent termination kit) $300 - $450

Install condensate drain, pump, acid neutralizer, etc. $250 - $300

* Adjusted using CPI (2009 vs. 2005)

APGA Comment: Implement AGA Survey Ranges of Installation Cost for Furnace Replacements of Category I Systems with Ca

and these ranges should be simulated as uniform cost distributions for the component costs. The AGA survey costs have bee

included in the DOE installed costs (e.g., drain pans) should be included as additional cost adders, either by including them ex

the case of the latter approach, DOE should document how it added costs to other cost categories.

Response: DOE used APGA Installation Cost Data and applied it to the LCC spreadsheet as shown in the table below.

Distribution (2009$)* Implementation

Replaced all chimney relining and resizing costs with this range (applied this 

range to cells k36, k37, k44, k46, k47, and k48 in "Installation Cost" worksheet 

in LCC Spreadsheet).

$165 - $275

Replaced Condensate Drain Pan value with this range (cell k53 in "Installation 

Cost" worksheet in LCC Spreadsheet).

$220

Replaced Condensate Heat Tape (Freeze Protection) value with this range (cell 

k52 in "Installation Cost" worksheet in LCC Spreadsheet). Assumed that this 

cost range includes electricity outlet costs (therefore, set cell k50 equal to 

zero).

$330 - $494

Replaced all components of Plastic Venting Installation Costs (Flue Venting 

(Plastic Vent); Concealing Plastic Venting (Retrofit Only); Combustion Air Pipe 

(Direct Vent)) values with this range (applied this range to cell k40 and set cell 

41 and cell42 equal to zero in "Installation Cost" worksheet in LCC 

Spreadsheet).

AEO 2011 High Shale EUR Scenario 

Note: AEO 2011 High Shale EUR Scenario is based on: "The total unproved technically 

recoverable shale gas resources are increased from 827 trillion cubic feet in the Reference 

case to 1,230 trillion cubic feet. The estimted ultimate recovery per shale gas well is 50 

percent higher than in the Reference case."

AGA Comment: DOE should use a marginal price analysis when evaluating the impact of natural gas 

prices on the life-cycle-cost savings associated with conservation standards.

Response: DOE derived natural gas marginal price factors based on RECS 2005 billing data.
