H&C supplies and installs the GTA's top tankless water heater brands — Rinnai, Noritz, and A.O. Smith — backed by TSSA-licensed technicians and 24/7 support.
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.

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.

"H&C installed our Rinnai tankless in one day. No more cold showers for our family of five — the fifth shower is just as hot as the first. Worth every penny."
