How it Works

electric water heater whole house

Electric tankless water heaters are quickly growing in popularity given their potential energy savings and ability to deliver hot water on demand. Electric tankless water heaters assist in reducing the energy consumption within your home by not having to heat water in storage tanks that goes unused. Reliance electric tankless models perform with high efficiency ratings and groundbreaking designs. They serve a wide range of applications, whether it be point-of-use or whole-house. These models deliver continuous hot water when you need it and they can be easily installed in places where tank water heaters can’t go, including closets and bathrooms.


Electric tankless water heaters heat your home’s water on demand. When a hot water tap is turned on, water from your pipes enters the water heater and passes through the heat exchanger. Within the heat exchanger, there is an electric resistance coil that warms the water to the desired temperature as it travels through. When sized appropriately, a constant supply of hot water is delivered to your home with ease.

Still Have Questions?

Both electric tank and electric tankless water heaters have their specific advantages. Electric tankless units can potentially help you save on home energy use and provide continuous hot water on demand. However, you should consider your usage preferences, energy supply, and space considerations when talking with your local water heater service provider.

Reliance electric tankless water heaters can provide hot water on demand and energy savings, all while taking up less space in your home. We recommend talking to a licensed professional before making the final decision on a water heater purchase. They will be able to offer guidance regarding electrical service requirements and any additional components needed for installation.

There is a potential to save energy with electric tankless water heaters. The electric tankless unit will only heat the water that you use and does not have the standby heat loss that typically comes with traditional tank-type products.

Industry-leading Reliance electric tankless water heaters include a 5-year limited warranty. While the lifespan of an electric tankless water heater can vary, factors like water conditions, usage rates and maintenance all contribute to your water heater’s health. You can help your tankless unit run longer and at optimal efficiency with routine maintenance and descaling.

Electric tankless products do work in cold climates. However, there are a few things to keep in mind. Colder climates mean colder incoming groundwater temperature, resulting in a need for more energy to heat the water to your desired temperature. Colder incoming groundwater temperature will limit the product options to the higher kW units, which require a larger electrical service and breaker size capacity. If there is adequate electrical service and room in the breaker panel, electric tankless is a great option.

Electric tankless units install similarly to an electric tank-type product. All you need is electricity and water. When having an electric tankless water heater installed by a professional, be aware of the electrical service requirements, the additional wires needed for installation, and your home’s climate. We recommend talking to a licensed professional before making the final decision on a water heater purchase.

  • Size?
  • The factors that will affect the size of your electric tankless water heater are the incoming groundwater temperature, hot water flow rate required, electrical service, and breaker panel restrictions.
  • Where to install?
  • Electric tankless water heaters can be installed in any location within your home with the appropriate hookups. Their compact size frees up valuable space within your home. Common applications include offices, lavatories, and remote fixtures.
  • Venting? No venting is required for Reliance electric tankless water heaters.
