Upgrade Path	Annual Gas Savings	15-Year Total	Payback (No Rebate)
60% → 96% AFUE	$520 – $840/yr	$7,800 – $12,600	3 – 5 years
80% → 92% AFUE	$165 – $280/yr	$2,475 – $4,200	4 – 8 years
80% → 96% AFUE	$233 – $420/yr	$3,495 – $6,300	3 – 6 years
80% → Heat Pump	$500 – $1,100/yr*	$7,500 – $16,500*	5 – 10 years*
96% → 98% AFUE	$30 – $60/yr	$450 – $900	15 – 30 years

*Heat pump savings combine furnace gas reduction + AC electricity savings. Burlington Enbridge commodity rate ~$0.138/m³. Annual heating gas consumption estimated ~1,800–2,600 m³ for average Burlington two-storey.

Understanding the Math Behind Furnace Efficiency Savings

AFUE is straightforward: a furnace rated at 80% AFUE converts 80% of each cubic metre of natural gas into useful heat. The remaining 20% exits as flue gas. A 96% unit loses only 4% to exhaust — meaning it requires far less gas to produce the same heat output.

To estimate your savings without the calculator: take your annual heating-only gas cost (approximately 65–70% of your total Enbridge bill, since the rest goes to hot water and cooking), multiply by (1 − old AFUE/new AFUE). Example: $1,600 heating gas × (1 − 80/96) = $1,600 × 0.167 = $267/year saved. That's the efficiency saving from the furnace alone, before accounting for reduced repair frequency on a newer system.

Annual Heating Gas Cost	Savings: 80% → 96%	Savings: 80% → 96% + Rebate	Payback (Rebate)
$900/yr	$150/yr	$150/yr + $500 rebate	2 – 5 years
$1,400/yr	$233/yr	$233/yr + $500 rebate	2 – 4 years
$1,800/yr	$300/yr	$300/yr + $750 rebate	1 – 3 years
$2,200/yr	$367/yr	$367/yr + $1,000 rebate	1 – 3 years

✓ Burlington-Accessible Rebates That Improve Payback

Canada Greener Homes Grant:

Up to $5,000 for qualifying cold-climate heat pump installations — if replacing with a heat pump, this dramatically compresses the payback period

Enbridge Home Efficiency Rebate+:

Rebates on qualifying 96%+ AFUE furnace upgrades for Enbridge customers — Burlington is in the Enbridge service area; check current available amounts seasonally

Alectra Smart Thermostat Rebate:

Up to $125 for qualifying smart thermostats that optimize furnace scheduling — easy to stack with a furnace replacement and often overlooked

Stacking federal + provincial/utility rebates is permitted — Burlington homeowners replacing furnace + AC together with a heat pump have received $3,500–$7,500+ in combined incentives

Frequently Asked Questions

How do I find my current furnace's AFUE rating in Burlington?

Three ways: check the yellow EnerGuide label on the furnace unit itself; search the model number in the AHRI certified products directory at ahridirectory.org; or use the installation year as a proxy. Furnaces installed in Burlington before 1992 are likely 60–72% AFUE (older induced-draft or gravity units). Units from 1992–2009 are typically 78–80% AFUE. Post-2009 standard installations are 80%. Anything marketed as "high efficiency" from 2006 onward is generally 92–96% AFUE. If you can see pilot light flames through a viewing port, it's a conventional (80% or lower) unit — high-efficiency furnaces have electronic ignition only.

My Burlington Enbridge bill is $2,800/year. How much is heating vs. everything else?

For a typical Burlington home, approximately 65–72% of annual Enbridge gas consumption is space heating, 18–22% is domestic hot water, and the remainder is cooking and other uses. On a $2,800 annual bill, that's roughly $1,820–$2,015 for heating. That heating portion is the number your furnace efficiency acts on — the hot water heater, stove, and fireplace run at their own efficiencies and aren't affected by furnace replacement. The savings calculator uses this split to isolate furnace-specific savings from your total bill.

Is it worth upgrading from 96% to 98% AFUE in Burlington?

Almost never purely for the 2% efficiency gain. The annual gas savings from 96% to 98% AFUE on a typical Burlington home run $30–$60/year — and the premium for a 98% variable-speed unit is typically $1,000–$2,000 over a comparable 96% model. That's a 20–50 year payback on the efficiency difference alone, which exceeds any realistic equipment lifespan. Variable-speed furnaces that achieve 98% AFUE are worth considering for their comfort improvements — more even temperatures, quieter operation, better dehumidification — not the 2% efficiency difference. Buy the variable-speed for comfort; the extra AFUE is incidental.
