  • Electrical requirements: The heater requires a dedicated electric circuit with specific amperage and voltage requirements. Consult a professional electrician.
  • Ventilation: Electric tankless models don’t need a flue or vent but may need ventilation.
  • Space: Smaller footprint allows for flexible placement in the home or office, but must be accessible.
  • Location is key – it should be easy to access in emergency scenarios.

Electric heating dates back over 100 years. Now modern technology lets us use energy-efficient appliances such as electric tankless water heaters. Check also: Fixing Hot Water Heater Leaking.

Which electric tankless water heater has a high flow rate?

One electric tankless water heater that stands out for its high flow rate is the Ecosmart ECO 27. This unit has a maximum flow rate of 6.5 gallons per minute and can provide enough hot water for multiple showers or appliances running simultaneously.

Additionally, it has self-modulating technology that adjusts the unit’s power consumption based on demand, resulting in even greater energy savings.

Another option with a high flow rate is the Stiebel Eltron Tempra Plus 36 KW Tankless Water Heater. It boasts a maximum flow rate of 7.

Should I oversize my tankless water heater?

One of the main reasons why someone might choose to oversize their tankless water heater is for future-proofing purposes. If you anticipate that your household will grow in size or your hot water needs will increase over time, then investing in a larger unit now could save you money in the long run.

Additionally, if you live in an area with particularly cold groundwater temperatures or hard water, then an oversized unit can help ensure that you always have enough hot water on demand.

Can an electric tankless water heater run a whole-house?

The answer is yes, an electric tankless water heater can run a whole-house, but it depends on several factors.

Firstly, the size of your home and number of occupants will determine the size of electric tankless water heater needed. A unit too small for the household’s needs will not be able to provide enough hot water to meet demand.

Secondly, you need to consider your home’s electrical capacity as electric tankless systems require high amounts of electricity to operate. Upgrading your electrical panel may be necessary in order to accommodate this increased load.
