The H&C Difference

Installed by People Who Know Tankless

40%Lower Bills

Up to 40% Lower Bills

Tankless units only fire when you open a tap — zero standby heat loss. Most GTA homeowners save 20–40% on water heating costs versus a traditional tank.

∞Endless Hot Water

Truly Endless Hot Water

No tank to deplete — the 5th shower of the morning is just as hot as the 1st. Ideal for busy families running multiple fixtures simultaneously.

20+Year Lifespan

20+ Year Lifespan

Tankless units last twice as long as conventional tanks and are fully repairable. Wall-mounted design frees up valuable utility room floor space.

* Estimates based on Ontario average natural gas rates and typical tankless system performance. Actual savings vary. Installation cost assumed at ~$3,000. Individual results depend on usage patterns, water temperature, and local gas rates.

How a Tankless System Saves Energy Year-Round

Morning Rush: Tankless fires instantly — no waiting for a tank to recover between showers.
Standby Loss Eliminated: Tank heaters waste 15–20% of energy keeping water hot 24/7 — even when no one's home.
Back-to-Back Showers: Endless hot water on demand — tank systems run cold after 2–3 showers.
Long-Term ROI: Tankless units last 20+ years vs. 10–12 for tanks — better value over time.

FAQ

Frequently Asked Questions

Common questions about tankless water heater installation, sizing, and maintenance in the GTA

Most tankless installations take 4–6 hours. A full swap from a traditional tank to a new tankless unit — including draining and removing the old tank, running new gas/venting lines if required, and commissioning the new system — is typically completed in a single day by our TSSA-licensed technicians.
