Questions and Answers

Customer Questions

How many showers can this tankless water heater support simultaneously?

With a 199,000 BTU capacity and an 11.1 GPM max flow rate, it supports up to 4 showers at once in warm climates, and 2 to 3 showers at once in colder northern climates where incoming water temperatures are lower.

Why is the EZ Series advertised as a "direct tank replacement" unit?

This unit features top-mounted water connections that align with the plumbing setup of traditional storage tank water heaters. Unlike standard tankless units with bottom connections, this design minimizes the need for extensive re-piping, helping reduce installation time and labor costs.

Can I run this model on Liquid Propane (LP) if I don’t have Natural Gas?

No. This model is factory-configured for Natural Gas (NG) only and cannot be used with propane as-is. If your home uses liquid propane, you will need to purchase the dedicated LP version.

Do this tankless unit requires professional maintenance?

No, basic maintenance is straightforward. To help prevent mineral scale buildup and ensure optimal performance, this unit simply requires an annual vinegar flush of the heat exchanger and periodic rinsing of the built-in, cleanable water filter.

Can this unit be installed outdoors, or is it indoor-only?

This unit is approved for both indoor and outdoor residential installations. For outdoor setups, it includes built-in freeze protection down to -30°F (-34°C). However, an optional outdoor vent cap is required to protect the exhaust opening from weather exposure.
