Find the right fit for peak use

List the showers, sinks, and appliances likely to run together. That gives us a starting point for estimating peak flow and the temperature rise the heater needs to deliver.

Plan the conversion

A conversion may need changes to venting, gas supply, electrical service, or condensate handling. The installation site helps determine which models are appropriate and what the project involves.

Keep performance consistent

Manufacturer-recommended maintenance can include descaling and cleaning an inlet screen. If you notice a change in flow or temperature, share the model and any error code when you call.

Common question

Does tankless mean instant hot water at the tap?

A tankless unit heats water on demand. Hot water still takes time to travel to the fixture. A compatible recirculation setup may help where the pipe run is long.
