Electrical Requirements for an EcoSmart Electric Tankless Water Heater

Please see the chart for electrical requirements:

The above specifications are only guidelines. Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

If your home is already equipped with a large number of electrical appliances, you may require a larger electrical service than the one recommended above. Please consult an electrician before placing an order.

If your home does not have the minimum household electrical service as specified for your desired model, you can still purchase an ECOSMART electric tankless water heater, however, upgrades to your electrical service will likely be required. It is recommended that you consult your certified electrician prior to purchasing.
