How much can I save on heating by upgrading insulation in a Moncton home? | Insulation IQ?

Heating savings from an insulation upgrade in Moncton depend on several variables — your current insulation levels, the heating system you use, your home's age and construction type, and how thoroughly air sealing is addressed alongside the insulation work. That said, real-world results from NB homeowners and energy modelling data give us a solid picture of what to expect.

Moncton sits at approximately 4,500 to 4,700 heating degree days annually, making it somewhat milder than Edmundston or Campbellton but still firmly in ASHRAE Climate Zone 6 territory. The typical pre-1980 Moncton home — a common house type throughout the older residential areas of the city — was built with R-8 to R-12 in the attic, minimal or no basement wall insulation, and 2x4 walls with R-11 fibreglass batts at best. These homes lose enormous amounts of heat through the building envelope, and insulation upgrades in this context deliver some of the highest returns available in home improvement.

Upgrading an attic from R-10 to R-60 in a typical 1,400 sq ft Moncton bungalow can reduce attic-related heat loss by 60 to 75 percent. In a home heated with electric baseboard (common across Moncton), this single measure alone often saves $400 to $800 per year on the NB Power bill. In oil-heated homes, the savings translate similarly to 150 to 300 litres of fuel oil annually — worth $300 to $600 at current prices.

Adding basement wall insulation (bringing an uninsulated concrete wall to R-20) addresses what is typically the second-largest heat loss pathway in a Moncton home. Basement walls in contact with cold soil lose heat continuously through the heating season. Insulating a full basement to code levels typically saves an additional $200 to $500 per year depending on basement size and heating fuel.

Air sealing, done in conjunction with insulation, is arguably the highest-return measure in older Moncton homes. Heat loss through air leakage — around the electrical boxes, plumbing penetrations, rim joists, attic hatches, and top plates — can account for 30 to 40 percent of a home's total heat loss. A comprehensive air sealing treatment combined with attic insulation commonly achieves bower door test results of 2.0 to 3.0 ACH50 or better, down from 6.0 to 10.0 ACH50 in an unsealed older home. This can add $300 to $700 per year in additional savings on top of the insulation work itself.

For a typical 1960s to 1980s Moncton home doing a comprehensive upgrade — attic to R-60, basement walls to R-20, rim joists spray foamed, and thorough air sealing — total annual heating savings commonly land in the range of $1,000 to $2,000 per year. At those savings rates, a project costing $12,000 to $18,000 has a simple payback period of 8 to 15 years, well within the lifespan of the improvements themselves. If NB Power rebates ($2,000 to $3,500) and any available federal incentives are applied, the payback shortens considerably.

Heat pump adoption has changed the savings calculation in recent years. Many Moncton homeowners have installed mini-split heat pumps and use them as primary heating for most of the season. In this scenario, insulation upgrades allow the heat pump to run more efficiently and cover a larger portion of heating demand before backup resistance heat is needed, magnifying the savings from both the insulation and the heat pump together.

The most accurate savings estimate for your specific home will come from an EnerGuide home energy assessment, which models your actual house geometry, construction type, and heating system. These assessments are available from NB Power-approved energy advisors and are the first step in qualifying for both provincial and federal rebate programs.
