Heat Pump ROI Report
Measured from your bills — not a rule of thumb. Sample — no elevation lapse correction (site ≈ ERA5 grid cell).
Balance point 15.5 °C · fit CV(RMSE) 6.2%

Heat-pump sizing (bin analysis)
Mitsubishi Zuba Central 3-ton (PUZ-HA36NKA, cold-climate ducted)
- Compressor
- 5,066 kWh/yr
- Aux (resistance)
- 0 kWh/yr
- HP balance point
- -22.5 °C
Below the heat-pump balance point the compressor can't meet the load and electric backup (aux) makes up the deficit — counted separately, never blended into the COP.
Operating cost (marginal rate)
- HP electricity
- $748 CAD/yr
- Gas displaced
- $993 CAD/yr
- Gas basic (kept)
- $162 CAD/yr
- Annual saving
- $246 CAD/yr
Priced at the marginal tier your added load lands in — a blended average would understate it by $116 CAD/yr.
Payback
Simple payback is ~8 years against a ~15-year equipment life.
- Equipment
- $13,000 CAD
- Install labour
- $5,000 CAD
- Rebates
- −$16,000 CAD
- Net install
- $2,000 CAD
The no-regret call
Heat Pump Favourable
The envelope, load split, and payback all point the right way — a heat pump is a defensible move for this building at current rates and rebates.

Analyze My Bills →Estimates from a measured energy signature and published utility rates and rebate programs, for planning only — not an engineered heat-loss calculation, a rate quote, or a guarantee of rebate eligibility. Equipment performance is modelled from the NEEP cold-climate ASHP directory rating points for the named unit; real installed performance varies with ducting, refrigerant charge, and controls. Confirm sizing, rates, and rebates with a licensed contractor before purchasing.
