Canada's cold winters make hot water reliability non-negotiable. But traditional tank heaters waste energy keeping 40–60 gallons warm around the clock — even at 3am when nobody is home. Point-of-use tankless water heaters solve this differently: they heat water instantly, only when you need it, right at the tap.
What Is a Point-of-Use Tankless Water Heater?
A point-of-use (POU) tankless water heater is a compact unit installed directly at the fixture — under a kitchen sink, in a bathroom cabinet, or mounted on the shower wall. Unlike whole-home systems, POU units heat water on demand as it flows through, with zero standby heat loss. No more running the tap for two minutes waiting for warmth to travel up from the basement.
For Canadian homes and businesses, the advantages are significant: energy savings, space savings, and consistent hot water with no tank-refill delays during high-demand mornings.

Why Canadians Are Switching to Tankless
The energy savings are the headline, but the full picture is more compelling:
- No wait time. Hot water arrives in seconds — especially valuable in larger Canadian homes where water travels long pipe runs before reaching you.
- Space savings. Under-sink units eliminate the 40-gallon tank dominating your utility room or basement.
- Freeze-resistant design. No tank of standing water to freeze during extreme cold snaps. The heating element is only active when water flows.
- Longevity. Tankless units typically last 15–20 years vs. 8–12 years for conventional tank heaters.
- Energy efficiency. Eliminating standby losses cuts 15–20% of a typical home's hot water energy use — meaningful savings on a Canadian hydro bill.
What to Look for When Buying in Canada
Voltage requirements. The TapHeat 3.5kW Mini runs on 120V (standard Canadian outlet). Higher-wattage units (5.5kW+) require a dedicated 220V/240V circuit. Most Canadian homes have capacity in the electrical panel — check before purchasing.
Match flow rate to use case. Handwashing sinks need 0.5–1.0 GPM. A shower typically needs 1.5–2.5 GPM. Always match the unit's rated GPM to the fixture it serves.
Installation. Under-sink models install in 10–30 minutes if the water line and outlet are accessible. Wall-mount models require a cold water connection and an electrical hookup — a straightforward DIY job once the circuit is in place.
