Heat Pump vs Boiler Radiator: Which Is Better for Toronto Homes?

Toronto homeowners, especially those in charming older houses, often have to choose between modern heat pumps and classic boiler radiators for heating. Which is the smarter choice for comfort, energy savings, and future-proofing your home? Here’s a complete comparison from the experts at Temperature Care.

How Do They Work?

Boiler Radiator:

A central boiler heats water (using natural gas, oil, or electricity)
Hot water or steam circulates through pipes to cast-iron or modern radiators, radiating warmth into each room
Provides even, comfortable heat—ideal for drafty or older Toronto homes

Heat Pump:

Transfers heat from outdoors to indoors using electricity (and reverses for cooling)
Can be ducted (using existing ducts) or ductless (mini-split, with wall-mounted indoor units)
Heats and cools your home with unmatched energy efficiency

Efficiency and Cost

Feature	Heat Pump	Boiler Radiator
Efficiency	200–350% (COP 2–3.5)	80–95% (newer models)
Fuel Source	Electricity	Gas, oil, or electricity
Heating Style	Air (or radiant w/ hydronic)	Radiant, quiet, draft-free
Cooling	Yes (AC built in)	No
Operating Cost	Lower, big hydro savings	Higher, volatile fuel cost
Upfront Cost	Higher, but rebates available	Lower (if existing)

Heat pumps qualify for generous rebates:
- Canada Greener Homes Grant
- Enbridge Home Efficiency Rebate Plus

Comfort and Air Quality

Boiler radiators:
- Silent, draft-free, and moist radiant heat—great for people with allergies
- No air movement, so dust stays settled
- Only provides heating (no summer cooling)
Heat pumps:
- Provide both heating and cooling
- Filter and circulate air, improving air quality
- Flexible: install as a central system or mini-split for zoned control

Installation & Maintenance

Boiler radiators:
- Great if your home already has them, but you may need upgrading for efficiency
- Requires annual boiler service and periodic radiator bleeding
Heat pumps:
- Can use existing ducts or go ductless (ideal for older homes)
- Require annual maintenance check—generally lower maintenance than boilers

Environmental Impact

Heat pumps:
- Super low emissions, especially in Ontario’s green electricity market
Boilers:
- Produce carbon emissions unless running on electricity, which is less common and efficient

Which Should You Choose?

Choose a heat pump for the highest energy savings, year-round comfort, and future-proofing your home.
Stick with boiler radiators if you love radiant heat, want ultra-quiet heating, or can’t upgrade your electrical panel yet.
