Tankless water heater services
Tankless water heater systems, also known as on-demand or instantaneous water heaters, offer numerous exciting advantages over traditional tank water heaters. Our certified technicians handle everything from offering customized recommendations to tank or tankless water heater repair in Toronto
Why Toronto Homeowners Are Switching to Tankless Water Heaters
- Unlimited on-demand hot water - End the “last-shower-is-cold” problem—tankless units heat water the instant you open the tap, sized to your household’s peak GPM flow
- Zero standby heat loss → lower utility bills - No 40-gal tank constantly reheating; NRCan studies show 20–40 % energy savings for Toronto’s climate zone
- Space-saving wall mount - About the size of a carry-on suitcase, freeing floor space in condos & basements
- Cleaner, fresher water - Water isn’t stored for hours, reducing rust and scale contamination
- Longevity and Durability
Built to last 20 + years
Tankless water heaters typically last longer than traditional tank systems. Quality heat exchangers + modular parts outlive tank heaters by a decade
Lower maintenance load
No anode-rod corrosion or heavy sediment buildup means fewer service calls. With no tank to corrode or fail, tankless systems have fewer problems related to water quality (e.g., sediment build-up).
- Safety
Enhanced safety—minimal leak risk : Eliminates the chance of catastrophic tank rupture and flooding
Superior Water Quality :
With no water storage tank, the risk of rust and scale contaminating your water is significantly lowered, ensuring consistently clean and fresh water.

Tankless Water Heater vs. Conventional Hot-Water Tank
A tankless (on-demand) water heater heats water only when a tap opens, so there’s zero standby heat loss. Natural Resources Canada data show that cutting the “always-on” reheating cycle trims 20 – 40 % off annual energy use in Toronto’s climate, which can translate into Greener Homes rebate eligibility and roughly half a tonne less CO₂ each year. Because water isn’t stored in a steel cylinder, tankless units last 20 + years, mount neatly on a wall, and all but eliminate the flood risk that comes with a ruptured 180-litre tank.
A storage-type hot-water tank wins on lower upfront cost, but it continuously reheats 150 – 230 litres of water—even while you sleep—so utility bills stay higher and the anode rod eventually corrodes, giving most tanks an 8- to 12-year lifespan. Once the reservoir is empty, you wait 20-60 minutes for recovery, and sediment buildup means more maintenance visits.
Bottom line: If you value endless hot water, lower utility bills, and reclaimed floor space, tankless pays for itself within about five to seven years for most GTA households. Storage tanks remain a budget option when initial capital is the only consideration.
How a Tankless Water-Heating System Works
Water heating system are also known as on-demand water heaters. It does not have a storage tank and it heats water only when hot water is needed, thus avoiding stand-by heat loss through tank walls and water pipes. A tankless—or on-demand—water heater uses smart flow sensors instead of a storage tank. When you open a hot-water tap, the sensor signals a control board that instantly fires the sealed gas burner (or energises electric heating coils). Cold mains water rushes through a high-efficiency copper or stainless-steel heat exchanger, picking up heat as it passes.
Because water is heated only while it moves through the exchanger, there is no standby heat loss through tank walls or piping. For homes with recirculation loops or high simultaneous demand, the system can feed an optional buffer or storage tank, giving you both on-demand efficiency and a reserve supply.
