Choosing the Right Home Heating System in Ottawa

Ottawa winters demand a reliable, efficient heating system. But with different types of systems available, how do you know which one is best for your home? Let’s break down the most common heating systems, how they work, and what makes sense for Ottawa homeowners.

Types of Home Heating Systems

Most Ottawa homes are heated by one of three main systems:

Forced-air furnace (natural gas): The most common in Ottawa.
Boiler (hot water radiators): Less common locally, but still found in some older homes.
Heat pump (electric/air-source): Growing in popularity due to efficiency and year-round comfort.

At Ercan’s Heating and Cooling, we specialize in furnaces and heat pumps, as they are best suited to Ottawa’s climate and housing styles.

How Each System Works

Furnace: Burns natural gas to heat air, then distributes it through ductwork and vents.
Boiler: Burns natural gas to heat water or steam, which travels through pipes to radiators or baseboard heaters.
Heat pump: Moves heat between the outdoors and indoors using electricity—providing both heating in winter and cooling in summer.

Efficiency and Cost

Efficiency and operating costs vary by system:

Furnace: Rated by AFUE (Annual Fuel Utilization Efficiency). High-efficiency furnaces can reach 95%+. Heats quickly but requires venting for carbon monoxide.
Boiler: Also measured by AFUE. Boilers are very efficient and quiet, but they heat more slowly and lack cooling functions.
Heat pump: Rated by HSPF (Heating Seasonal Performance Factor). Very efficient and also serves as an air conditioner. In extreme cold, some models may need backup heating.

Suitability and Installation

Boilers are best suited for homes already built with radiators or hydronic piping.
Furnaces are ideal for houses with ductwork and are fast at heating.
Heat pumps can be installed with ductwork or as ductless mini-split systems, making them versatile for homes without ducts.

Pros and Cons

System

Furnace

Boiler

Heat Pump

Pros

Quick heating, affordable fuel, works with ducts

Quiet, efficient, long lifespan

Very efficient, heating + cooling, ductless options

Cons

Produces CO (needs venting), requires annual tune-ups

Slower to heat, no cooling, less common in Ottawa

May need backup in extreme cold, higher upfront cost

Lifespan and Maintenance

15–20 years / Annual duct & chimney checks

20–30 years / Annual boiler & radiator checks

15–20 years / Regular filter cleaning, system tune-ups

Local Climate Considerations

In Ottawa, all three systems are possible—but most homes already have ductwork, making furnaces and heat pumps the most practical choice. With advancements in high-efficiency heat pumps, they are now a reliable option even for colder winters, especially when paired with a backup heating source.

Making the Right Choice

Choosing the right system depends on your home’s setup, your budget, and your comfort preferences. An expert evaluation ensures you get a solution that keeps you warm while lowering long-term energy costs.
