Tankless Water Heater Installation in Etobicoke, ON
Imagine never running out of hot water mid-shower again. That's the promise of a tankless water heater — endless hot water on demand, better energy efficiency, and a compact unit that frees up space. But tankless units have specific installation requirements, and getting them right is what separates a system that performs beautifully for two decades from one that struggles. For professional tankless water heater installation in Etobicoke, ON, Waterworks Plumbing & Drains delivers properly sized, correctly installed systems that deliver reliable hot water for years.
Whether you're upgrading from a traditional tank, replacing an old tankless unit, or installing one in a new home, our experienced team helps you choose the right model and installs it safely and correctly — from gas and venting to the final performance test.
Why Choose a Tankless Water Heater?
Tankless (on-demand) water heaters work differently from traditional tanks: instead of constantly heating a stored reservoir, they heat water only as you need it. That difference brings several real advantages:
- Endless hot water — Hot water on demand, so you won't run out during back-to-back showers.
- Energy efficiency — Heating water only when needed reduces standby energy loss and can lower your bills.
- Space savings — Compact, wall-mounted units free up the floor space a bulky tank takes.
- Longer lifespan — Tankless units typically last around 20 years, well beyond a traditional tank's 10 to 15.
For many Etobicoke homeowners, those benefits make the switch well worth it.
Our Tankless Water Heater Installation Services in Etobicoke
We install tankless systems of all types and handle the requirements each involves.
Gas Tankless Installation
Gas tankless units are a popular, powerful choice. They require an adequately sized gas line and proper venting to operate safely and efficiently, both of which our team handles correctly.
Electric Tankless Installation
Electric tankless units suit certain applications and homes. We install them with the proper electrical connections to support their demand.
Tank-to-Tankless Conversions
Switching from a traditional tank to tankless involves more than swapping units — it often requires gas line, venting, and connection changes. We manage the full conversion so the new system works as it should.
Tankless Replacement
If you already have a tankless unit that's reached the end of its life, we remove it and install an efficient new model sized to your home.
Choosing the Right Tankless Unit
Proper sizing is critical with tankless units. Unlike a tank, which is sized by capacity, a tankless unit is sized by its flow rate — measured in gallons per minute — and the temperature rise it needs to deliver. In other words, the unit has to be able to heat enough water at once for everything you might run simultaneously, raising it from the incoming water temperature to your desired temperature.
An undersized unit will struggle to keep up when multiple fixtures run at once, while an oversized one costs more than necessary. We assess how your household uses hot water and recommend a unit sized to match, so you get consistent, endless hot water without overpaying.
What to Expect During Your Tankless Installation
Tankless installation has specific requirements that make professional work important. Here's how we approach it:
- Selection and sizing — We help you choose the right unit for your home's hot water demand.
- Gas line or electrical assessment — Gas tankless units often need an adequately sized gas line, which may require an upgrade; electric units need proper electrical capacity.
- Venting — Gas units require correct venting to safely exhaust combustion gases, using the venting type the unit calls for.
- Water connections — We connect the unit properly and securely to your plumbing.
- Mounting and setup — We mount the unit and configure it for your home.
- Testing — We test for safe, leak-free operation and proper hot water delivery before finishing.
Because tankless installation involves gas or electrical work and venting, professional installation protects your home and ensures the unit performs as designed.
Caring for Your New Tankless Unit
To get the full 20-year lifespan from your tankless heater, regular maintenance matters — and in Etobicoke that's especially true. The area's water is moderately hard (around 120 mg/L), and over time hard water leaves mineral scale on the unit's heat exchanger. Periodic descaling (flushing) removes that buildup, keeps the unit efficient, and prevents the error codes and heating problems that neglected units develop. We can set you up with the right maintenance routine from the start. And if your unit ever does act up, our tankless water heater repair service is here to get it running again.

FAQs
For many homeowners, yes. Tankless water heaters provide endless hot water on demand, use less energy by heating water only when needed, take up far less space than a tank, and typically last around 20 years — well beyond a traditional tank's 10 to 15. The trade-off is a higher up-front cost, and installation can be more involved, often requiring an adequate gas line and proper venting. Whether a tankless unit is worth it for you depends on your hot water usage, your budget, and your priorities around energy savings and space. We're happy to help you weigh the options for your home.
Tankless units are sized by flow rate (gallons per minute) and temperature rise, rather than by tank capacity. The unit needs to heat enough water for everything you might run at the same time — for example, two showers and a sink at once — while raising the incoming water to your desired temperature. A larger household or one that runs multiple fixtures simultaneously needs a higher-capacity unit, while a smaller home can use a smaller one. An undersized unit won't keep up during peak demand, and an oversized one costs more than necessary. A professional assessment of your hot water usage is the best way to determine the right size.
Yes, tankless units have installation requirements that differ from traditional tanks. Gas tankless models in particular often need an adequately sized gas line — which may require an upgrade — along with proper venting to safely exhaust combustion gases, using the specific venting type the unit calls for. Electric tankless units need sufficient electrical capacity. Because of these gas, venting, and electrical requirements, tankless installation is more involved than a simple tank swap and should be done by a qualified professional to ensure the unit operates safely and efficiently.
