Are heating-system retrofit and tune-up programs really increasing the efficiency of oil-fired systems?

Description

Oak Ridge National Laboratory conducted a two-year field test involving over 300 homes to evaluate the US Department of Energy Weatherization Assistance Program for low-income fuel-oil-heated houses. One conclusion was that houses receiving oil-burner clean and tune-ups did not increase in system steady-state efficiency any more than a similar group of weatherized and control houses not receiving clean and tune-ups. A set of oil-burner performance goals proposed by the Alliance to Save Energy were not attained by most of the tuned-up oil systems, thereby not achieving a major benefit of heating-system programs from current implementation methods. Whole-system replacements produced higher-than-average ... continued below

A set of oil-burner performance goals proposed by the Alliance to Save Energy were not attained by most of the tuned-up oil systems, thereby not achieving a major benefit of heating-system programs from current implementation methods. Whole-system replacements produced higher-than-average savings and systems with flame-retention burners had higher steady-state efficiencies and used less fuel than normal burners. Other space-heating-system measures including setback thermostats were not statistically significant in reducing fuel-oil consumption. Secondary benefits of improved safety (such as lowering carbon monoxide concentrations in flue gases and inside houses) and reliability were present in weatherized houses, although not in as high a quantity as is often espoused.
