**Case Description CASE 1:**  Fixed Furnace Lifetime of 16 years No Learning Curve APGA Installation Costs 2007 Furnace Final Rule Venting Weights

AEO 2011 Reference Case **CASE 2:** Apply Case 1 AEO 2011 High Shale Case **CASE 3:** Apply Case 1 Replaced LCC lifetime distribution (cell D5 in "lifetime" worksheet in LCC spreadsheet) with a fixed value of 16 years. Replaced learning curve price factor index (cell D99 in "Equip Price" worksheet in LCC spreadsheet) with 1 to represent no learning trends. **Implementation**

See "APGA Inst. Costs" worksheet. (*) No changes, since the 2011 Furnace DRF LCC analysis used similar weights as in 2007 Final Rule. (see "Venting Fraction Comparison" worksheet). Replaced regional AEO 2010 Reference Case prices with regional AEO 2011 Reference Case prices (cells BH9:DB40 in worksheet "Energy Price Trends" in LCC Spreadsheet). See "AEO Energy Price Trends" worksheet.

Replaced regional AEO 2011 Reference Case prices with regional AEO 2011 High Shale EUR Case prices (cells BH9:DB40 in worksheet "Energy Price Trends" in LCC Spreadsheet). See "AEO Energy Price Trends" worksheet. Applied Case 1 as described above.

Applied Case 1 as described above.

## Electric Water Heater replacement of 10% of

Orphaned Water Heaters

**CASE 4:** Apply Case 1 No Chimney Relining **CASE 1 + Natural Gas Marginal Prices** Apply Case 1

Natural Gas Marginal Prices Applied Case 1 as described above. Adjusted Energy Prices to account for Natural Gas Marginal Price Factors derived from RECS 2005 Billing Data (Marginal Price Factors multiplied times monthly energy prices by region in cells S25 to AD38 in "Energy Price" worksheet in LCC Spreadsheet). See "NG Marginal Price Factors" worksheet. Applied randomly to 10% of Orphaned Water Heaters. DOE used average equipment prices, installation costs, and energy use values from the 2010 Water Heating Final Rule (http://www1.eere.energy.gov/buildings/appliance_standards/residential/heating_products_fr.html). Because the average total installed cost of switching to an electric storage water heater (ESWH) ($1,005) is higher than the average cost of relining ($848) for a new gas storage water heater (GSWH), switching only occurs when the GSWH is at the end of its useful life. The average installed cost of a GSWH ($2019) includes the total installed cost of the water heater ($1,171) plus the cost of relining($848). The total installed cost of switching to an ESWH ($1005) includes both the total installed cost of the water heater ($710) plus the cost of adding electrical service ($295). On average, the consumer will see a total installed cost savings of ($1,014) when switching to an ESWH. But this is offset by the operating cost difference between gas and electric water heater. The operating cost is determined by calculating the average energy use for both ESWH and GSWH and multiplying the use by the appropriate energy prices. The average energy use for a ESWH is based on the average water consumption of 44 gallons/day and a baseline efficiency of 0.95 EF; for GSWH the same average water consumption of 44 gallons/day is used with a baseline efficiency of 0.62 EF (the energy efficiency standard in 2016). This results in 2,678 kWh/year for ESWH compared to 15.4 MMBtu/year for GSWHs. Applied Case 1 as described above. Set Chimney Relining variable (cell F13 in "Installation Cost" worksheet in LCC Spreadsheet) equal to 0).

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 Category IV. The following table of installation costs is from the AGA survey data, and these ranges should be simulated as uniform cost distributions for the component costs. The AGA survey costs have been previously submitted to DOE and are in the rulemaking docket. Costs not included in the DOE installed costs (e.g., drain pans) should be included as additional cost adders, either by including them explicitly as new cost categories or added to other, existing cost categories. In 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.

## Cost Data Range Applied

**in LCC Spreadsheet using a Uniform**  **Distribution (2009$)*** **Implementation**

$659 - $1,098 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).

$275 - $330 Replaced Condensate Pump value with this range (cell k51 in "Installation

Cost" worksheet in LCC Spreadsheet). Assumed that this cost range includes electricity outlet costs (therefore, set cell k50 equal to zero). Implement AGA Survey Ranges of Installation Cost for Furnace Replacements of Category I Systems with Category IV. The following table of installation costs is from the AGA survey data, and these ranges should be simulated as uniform cost distributions for the component costs. The AGA survey costs have been previously submitted to DOE and are in the rulemaking docket. Costs not included in the DOE installed costs (e.g., drain pans) should be included as additional cost adders, either by including them explicitly as new cost categories or added to other, existing cost categories. In the case of the latter approach, DOE should document how it added costs to other cost categories.

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

DOE used the following AEO price forecasts: **AEO 2010 Reference Scenario AEO 2011 Reference Scenario**  **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."
