Our Tankless Water Heater Installation Process

Every tankless water heater installation follows a structured process to ensure safe operation and compliance with Ontario regulations.

Step 1: In-Home Evaluation

We begin by assessing your home’s layout, reviewing household hot water demand, and confirming existing gas, venting, and electrical capacity. This allows us to determine the appropriate system requirements before installation begins.

Step 2: System Sizing and Capacity Verification

Correct sizing is essential for consistent performance. We calculate demand based on fixture usage and confirm that gas supply and venting meet the capacity requirements of the selected unit.

Step 3: Unit Installation and Connection

The system is mounted and connected using approved materials and fittings. Gas lines, venting components, and electrical connections are secured in accordance with provincial code standards.

Step 4: Testing and Code Confirmation

Before the system is placed into service, it is tested for proper ignition, steady temperature control, and stable operation. A final inspection ensures the installation meets Ontario safety requirements.

Benefits of Switching to a Tankless System

Switching from a traditional tank system to a tankless unit changes how water is heated in your home. Instead of storing a large volume of water, the system heats water as it is needed, improving efficiency and reducing unnecessary energy consumption.
Hot water on demand: Water is heated instantly as it moves through the system, providing a consistent supply without waiting for a storage tank to refill.
Lower impact on your utility bill: Because there is no stored volume to reheat, the system uses less fuel during normal operation, which can reduce monthly utility costs.
High efficiency ratings: Certain high-efficiency tankless systems are rated up to 0.96 on the energy factor scale, indicating reduced energy loss during operation.
Compact wall-mounted design: Tankless models are compact and free up valuable floor space in a basement or mechanical area.
Reduced risk of tank leaking: Eliminating a large storage tank removes the potential for tank leaking and water damage over time.
Long service life: With proper maintenance, many systems can operate reliably for up to 20 years.
If you are considering a tankless water heater for your home, our team can review your household usage and recommend a suitable option.

Condensing vs Non-Condensing Tankless Water Heaters

Tankless systems are available in two primary configurations. The difference comes down to how each unit manages exhaust heat and overall efficiency.
Feature Condensing Tankless Non-Condensing Tankless
Heat Capture Uses a secondary heat exchanger to condense exhaust gases and recover additional heat Uses a single heat exchanger and vents exhaust directly
Energy Factor Rating Typically higher, with some systems rated up to 0.96 Moderate rating, still more efficient than a traditional tank
Fuel Usage Uses less fuel during operation Slightly higher fuel consumption compared to condensing
Venting Requirements PVC venting Metal venting required
Installation Cost Higher upfront investment Lower upfront cost
Suitability for Canadian Climate Well-suited for colder climate conditions Suitable for many homes, depending on layout
Both options provide reliable hot water on demand, but installation requirements and operating efficiency can vary. Our team can review your home layout and recommend the right system for your needs.

Find Your Best Option

Does a Tankless Water Heater Save Money?

In many homes, yes. A tankless system heats water only when it is needed, which reduces standby energy loss compared to a traditional tank.
A traditional tank reheats stored water throughout the day
An on-demand system operates only during active usage
Reduced standby heating can lower energy consumption
Actual savings depend on usage patterns and fuel type
While results vary by household, many homeowners see a reduction in monthly utility costs over time.

Tankless Water Heater FAQs

What is the cost of installing a tankless water heater in Ontario?

Installation costs vary depending on venting, gas supply, and whether existing infrastructure needs upgrading. Homes switching from tank water heaters may require adjustments to gas lines or electrical connections. Most projects depend on system size, measured in gallon demand capacity, and overall installation complexity.

How long does a tankless water heater last?

With proper maintenance, a tankless system can last up to 20 years. Unlike traditional storage tanks that continuously reheat water, modern systems use controlled heating technology and durable internal components designed for extended service life.

Can a tankless system reduce monthly energy bills?

Because water is heated only during active usage, energy efficiency can improve compared to systems that store and reheat water throughout the day. Many high-efficiency gas tankless units operate without a standing pilot and use electronic ignition, which reduces unnecessary fuel consumption.

Is there a downside to installing a tankless water heater?

Initial installation costs are typically higher than standard systems. In some homes, gas upgrades may be required, particularly if the system must support multiple simultaneous fixtures. Proper sizing based on the number of people in the home is essential for consistent performance.

What maintenance is required for a tankless water heater?

Annual service is recommended to remove mineral buildup and inspect internal components. Systems with a built-in recirculation pump should be checked to ensure proper flow and performance. Routine maintenance helps prevent cold water fluctuations and supports long-term reliability.

Does the brand of a high-efficiency tankless system affect utility costs?

Different manufacturers use varying internal designs and efficiency ratings, such as UEF. Some models include a built-in recirculation pump or systems similar to a ComfortFlow system to improve delivery. Proper installation matters more than brand alone in overall performance and operating cost.
