Key Features

Endless Hot Water
No tank means no running out. The RL94eP heats water on demand — shower, wash dishes, and run the laundry all at once. Hot water flows as long as you need it.
Condensing Efficiency
A secondary stainless steel heat exchanger captures heat from exhaust gases that non-condensing units waste. The result: 0.93 UEF and noticeably lower gas bills.
Wi-Fi Control
Monitor and adjust your water heater from your phone. Set temperature, check status, and receive maintenance alerts. The Rinnai app makes managing your hot water effortless.
Space Savings
Mounts on an interior or exterior wall — freeing up the floor space a traditional 40-60 gallon tank occupies. Perfect for utility closets, garages, or mechanical rooms.
Scale Detection
Built-in scale detection alerts you before mineral buildup affects performance. Scheduled flushing keeps the unit running at peak efficiency for 15+ years.
12-Year Heat Exchanger Warranty
Rinnai backs the RL94eP with a 12-year residential heat exchanger warranty and 5 years on parts. H&C handles all warranty registration for you.

Frequently Asked Questions

How does a tankless water heater work?
Instead of storing 40-60 gallons of preheated water, a tankless unit heats water on demand as it flows through the heat exchanger. When you turn on a hot water tap, cold water enters the unit, gets heated instantly, and flows to your fixture. When you turn it off, the unit shuts down — no standby energy waste.
Will I really never run out of hot water?
Correct — as long as you stay within the unit's flow rate capacity. The RL94eP delivers up to 9.8 GPM, which is enough for 3+ simultaneous showers in most Canadian homes. H&C sizes the unit to your household's peak demand so you never experience a cold surprise.
How much will I save on energy bills?
Most homeowners save 20-40% on water heating costs compared to a standard tank. Tank water heaters lose heat 24/7 through the tank walls (standby loss). A tankless unit only burns gas when you need hot water. The savings add up over the 15-20 year lifespan of the unit.
Can I replace my tank water heater with a tankless?
Yes — H&C handles the full conversion. We remove the old tank, upgrade your gas line if needed, install the new unit with proper venting, and commission the system. Most conversions are completed in a single day.
What maintenance does a tankless unit need?
Annual flushing with food-grade vinegar removes mineral scale from the heat exchanger. In hard water areas, H&C recommends installing a scale prevention system. We offer annual maintenance plans that keep your unit running at peak efficiency.
How long does installation take?
A tank-to-tankless conversion typically takes one day. This includes removing the old tank, upgrading the gas line (if needed), mounting the new unit, running the vent, and commissioning. H&C handles all permits and inspections.
