Important Pre-Purchase InformationPrior to purchasing your Stiebel Eltron Tankless Water Heater, it is important that you ensure that your home has sufficient electrical capacity for the desired model, or that you have budgeted for any upgrades that might be necessary. Please note that all electrical tankless water heaters, regardless of the manufacturer's claim, are restricted in reality to approximately 3 gallons per minute of flow at any given time in cold winter climates. This is generally more than enough for residential applications, however, certain simultaneous water usages in the home at single or multiple outlets may exceed this capacity. Please bear this in mind when selecting a model or system for your home. See the chart on our Tankless Water Heater Model Selector page for maximum flow capabilities based on your climate and model selected. Electrical Requirements for Stiebel Eltron Tempra Series Tankless Water Heaters:Before purchasing a Stiebel Entron, or any other electric tankless water heater, please ensure that your home has sufficient electrical capacity for your desired model, or that you have taken note of any upgrades that may be required.
* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. 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. The above specifications are only guidelines. 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. |
