Home Heating - Measure

Sector: Residential

    Policy Description: Develop energy efficiency programs for oil and gas-fired

    heating and hot water systems.

    BAU Policy/Program: LIHEAP, WAP, REACH Central Heating Improvement (CHIP)

    Programs for low-income residents. (Energy Advisors, LLC, 2003)

    Data Needs, Sources & Assumptions for Preliminary GHG Savings and Cost Estimates:

    ; Maine residential heating and hot water systems annually consume:

    o 272 million gallons of #2 fuel oil (EIA, Fuel Oil and Kerosene Sales, 2002, Table 19

     Adjusted Sales for Residential Use)

    o 1196.75 MMCF natural gas (EIA, Annual Natural Gas Deliveries to Residential, by

    State, 2003)

    ; Greenhouse gas emissions associated with residential heating in Maine is XXX CO2e

    ; 22 states have natural gas conservation programs. In the Northeast, NH, VT, MA, NY, NJ,

    PA, MD and WV have natural gas conservation programs. ME, RI, CT and DE do not.

    o Vermont’s natural gas conservation program has saved 1,000 cubic feet/year

    (typically lasting 20 years) for every $29 spent. (Grevatt, 2003).

    o Programs include:

    ; promoting ENERGY STAR heating equipment;

    ; promoting ENERGY STAR-rated water heaters;

    ; promoting ENERGY STAR-rated programmable thermostats;

    ; increasing the efficiency of residential new construction;

    ; Maine should review market and regulatory barriers to identify best opportunities for

    increasing installation of cost-effective efficiency measures, and review potential

    mechanisms for incentivizing and implementing these measures. For example,

    Recommended Improvment Estimated Savings

    Heating System Tune 2 to 10%

    Reduced firing rate or nozzle reduction 6 to 10%

    Reduced temperature of circulating water/furnace 5 to 12 %

    air

    Pipe and duct insulation 5 to 10%

    Flame retention head burner 15 to 20%

    New high-efficiency hot water boiler 20 to 40%

    New high-efficiency warm air furnace 20 to 40%

    ; Pilot program As part of a more comprehensive residential heating efficiency program,

    Maine could promote and incentivize the early retirement of inefficient furnaces/boilers to be

    replaced with ENERGY STAR furnaces/boilers, integrated hot water heaters, and the

    installation of set-back thermostats.
