Cost Comparison
Oil vs Heat Pump Cost in Connecticut (2026)
If your winter bill is the problem, this is the question that matters most: what will your yearly heating cost look like after a heat pump upgrade? The right answer depends on your home load, equipment efficiency, and local utility pricing.
Connecticut rate context for planning
- EIA state electricity profile reports Connecticut among the highest average retail electricity prices in the U.S. (24.37 cents/kWh in 2024 data release).
- EIA heating oil updates show significant weekly volatility in Connecticut during the 2025 to 2026 heating season.
- Utility supply rates and delivery charges change over time, so use your recent bill for final project sizing decisions.
