High Efficiency Plus Tankless Water Heaters

High Efficiency Plus tankless water heaters in this collection are gas-fired RL-family units that heat water as it flows through the appliance. They differ from storage tanks and condensing tankless models, so selection should begin with required hot-water delivery, approved location and fuel configuration.

Match Hot-Water Demand and Installation Type

The collection includes indoor and outdoor model references. Compare the exact appliance rather than applying one unit’s flow rate or installation method to the entire series.

Flow at Temperature Rise

Assess simultaneous fixtures and the rise from incoming to required water temperature. A maximum flow figure does not describe delivery at every Toronto winter inlet condition.

Indoor or Outdoor Model

Confirm the approved installation location and cold-weather requirements. An exterior-model listing is not confirmation that outdoor mounting is suitable for the proposed GTA property.

Gas and Venting

Verify fuel, gas supply capacity and the exact vent arrangement for the selected model. Replacing a storage heater or another tankless generation may require connection changes.

Non-Condensing Compared With Condensing Tankless

The RL High Efficiency Plus references belong to a non-condensing tankless family. Compare a condensing alternative using the complete installation requirements, including venting and condensate provisions where applicable.

Do not infer that all products labelled high efficiency use the same technology or efficiency metric. Use the documentation for the exact supplied model.

Replacement and Hot-Water Expectations

Record the existing model, fuel, vent system and household draw pattern. A same-brand replacement may still need different piping, controls or service provisions.

Tankless operation also does not by itself eliminate the wait for hot water to travel through the plumbing. Discuss distribution and any approved circulation arrangement separately from heater capacity.

Installed Cost and Current Availability

Confirm supply and replacement options for the listed older model references before ordering. A current product with a similar capacity may have different requirements.

Include gas and electrical work, venting, water connections, isolation for service, removal and commissioning. Compare complete installed packages rather than a heater price alone.

Prepare a Tankless Replacement Assessment

Gather household demand and existing installation details before choosing the unit. These checks clarify the appropriate package.

High Efficiency Plus Selection Checklist

Record simultaneous hot-water uses and required temperature.
Compare delivery at the stated temperature rise.
Confirm model, fuel and permitted location.
Assess gas supply and approved venting.
Review distribution and service-access requirements.

Choose the Heater Around Verified Delivery

Confirm hot-water demand and site suitability before selecting the model. A complete assessment helps distinguish a compatible replacement from a broader installation change.
