Space savings
A wall-mounted tankless unit frees up the floor space a large tank would occupy — often useful in finished basements and utility rooms.

Water Heaters / Tankless Water Heater Installation
— Why Homeowners Consider Tankless
Tankless isn't automatically better than tank — but for many GTA homes, it's a strong fit. Here's what tankless actually delivers when it's installed and maintained properly.
A wall-mounted tankless unit frees up the floor space a large tank would occupy — often useful in finished basements and utility rooms.
A properly sized tankless heats water on demand, so back-to-back showers don't run cold — as long as the unit is sized for peak flow.
No standby losses from keeping a tank hot around the clock. Well-suited to households with variable or moderate hot-water demand.
With proper installation and regular descaling, tankless units are engineered to outlast a typical tank meaningfully.
We size to your actual peak demand — showers plus a dishwasher, for example — so the unit performs the way it should.
Tankless units are built to be maintained. Parts are typically replaceable, and descaling keeps them running properly for years.
— What A Proper Install Requires
Tankless installs are more involved than tank swaps. Getting the details right up front is what separates a great install from a frustrating one.
Most tankless units require a larger gas line than a conventional tank. We verify supply size, meter capacity and pressure — not assume.
Sealed-combustion condensing units use dedicated PVC or stainless venting with clearances and condensate drainage handled properly.
Sized for peak flow across the fixtures you actually use at the same time — not just the label on the old tank.
Toronto-area water can scale a tankless unit over time. We discuss maintenance and, where appropriate, filtration or softening.
Every install includes isolation and service valves so descaling is straightforward — not a plumbing project.
Dedicated electrical for the unit's control board, plus proper condensate handling and recirculation setup if requested.

Neither is universally better. Tankless offers continuous hot water, saves space and can be very efficient; tanks are simpler, cheaper up front and don't require descaling. We recommend based on your home and how your household actually uses hot water.
A properly sized tankless heats water on demand, so back-to-back showers won't run cold. But it can only heat what it's sized for — running two showers and a dishwasher on a unit sized for one shower will exceed its capacity.
Often, yes. Most tankless units require more gas than a typical tank. We check line size, meter capacity and pressure and include any required upgrades in the written proposal.
Modern condensing tankless units use sealed PVC or stainless venting with dedicated intake and exhaust runs. We design and install that as part of the job — with proper clearances and condensate drainage.
Yes. Descaling is the most important thing you can do for a tankless unit. Skipping it leads to reduced output, error codes and, eventually, heat-exchanger damage.
They make a small fan and burner sound when firing, then go quiet again. Most homeowners find them no more intrusive than a furnace short-cycling.
Yes. Many modern units support recirculation loops or built-in recirculation for faster hot water at distant fixtures. We can plan that in when appropriate.
Yes. Financing is available for water heater installs. See our Financing page for details.
