Oil Heat Faces a $6-a-Gallon Test
Heating oil is about to get a lot more expensive. The Energy Information Administration expects average prices of $4.80 a gallon this winter, up 33% from last year, and one New York-area supplier has already charged $6.86. The jump is tied to tight global oil supplies and the wars in Iran and Ukraine, and it mainly affects Northeast homes that heat with oil. If your oil furnace or boiler is old, replacing it can still help even if you stay with oil. Industry data cited in the piece shows high-efficiency oil boiler swaps saving around 25% on fuel compared with older units, and oil-heated homes today burn less than half the fuel a similar home used in 1978. That said, a full switch to a heat pump (a system that moves heat instead of burning fuel) costs two to three times as much as simply replacing an oil system in some New England homes, with a payback period of six to seven years. One contractor quoted in the article says leads from oil customers asking about heat pumps are up 30%, and expects a strong sales season as prices bite. Electricity costs matter too, since New England rates are among the highest in the country. Massachusetts is trying to improve the math: it now requires major utilities to offer discounted winter rates for homes that heat primarily with heat pumps, which saved participating households over $250 last winter. Those discounts are getting bigger this year — National Grid's rate cut is rising from about 2.5 cents to 4 cents per kilowatt-hour, and Unitil's from about 2 cents to 3.6 cents. If you're in Massachusetts and considering a heat pump, it's worth checking whether your utility offers this rate.
help please- spray foam closed cell insulation disaster
A homeowner on the South Shore of Massachusetts is dealing with a spray foam insulation job gone wrong. Closed-cell spray foam (a dense, plastic-like foam insulation sprayed into attics and walls) was installed in their attic, and more than 35 days later it's still releasing a strong chemical smell. The installer tried blaming a separate fireproof coating, removed and replaced it, but the odor persisted. The family has been out of their house for over a month, through a range of fall temperatures, and say air quality tests show pollutant levels in a "moderate but elevated" range. They're now asking the installer to remove the foam entirely. Responses from building science forum members offered a blunt diagnosis: a bad chemical mix during spraying can leave foam that never fully cures, meaning it keeps off-gassing indefinitely. In cases like this, patching or adding more product rarely fixes the problem — full removal and specialized cleaning is usually the only real option. One commenter also noted that homeowners in this situation sometimes need to pursue legal action to get the cost of removal and cleanup covered. For homeowners considering spray foam insulation, the case is a reminder that improper mixing or application during installation can turn into a serious, long-lasting indoor air quality problem rather than a quick fix. If you ever notice a chemical smell lingering well beyond the first few days after a spray foam job, it's worth treating that as a sign something went wrong with the installation itself.
