With a sleek, wall-mounted design and state of the art technology, EcoSmart’s electric tankless water heaters have revolutionized the industry. EcoSmart will help you to Save Money, Save Space, and Save Energy. Hot water on demand is the key to conserving energy for consumers and for the environment.

Electric tankless water heaters are available for whole home use, point of use, radiant heating, and pool & spa applications. They can be used in residential, commercial, and industrial settings. EcoSmart is also great at heating water for recreational use in boats and RVs. The patented Self Modulating Technology and design allows you to save up to 50% on your water heating bills as compared to a storage tank.

EcoSmart electric tankless hot water heaters are 99.8% energy efficient and provide digital temperature settings in increments of 1 degree. Set it and forget it. With experienced customer service and a limited lifetime warranty, EcoSmart is the perfect choice for your water heating needs.


– 99.8% thermal energy efficiency. Most water heater tanks are only 65% efficient.

– No standby heat loss. Heats water when you want it, instead of keeping water hot 24/7

– Saving energy reduces your carbon footprint.



– EcoSmart provides you with a limited lifetime warranty, ensuring that you will enjoy their product for the long haul.

– EcoSmart electric tankless water heaters are 90% smaller than a tank type heater, allowing you to place them almost anywhere.

– Because they are so small, they can be installed at the point of use, so you don’t have to waste water waiting for your water to heat up.


– Tankless water heaters can last over 20 years, much longer than any other water heater.

How electric tankless water heaters work

Cold water goes in one side, is heated “instantly,” and goes out the other side.

“On Demand” is a better description. Although the water is heated “instantly,” it still needs to pass through pipes so hot water will not arrive instantly.

One huge advantage of an electric tankless water heater is the ability to install it closer to the point-of-use. This reduces the amount of travel time within the pipes and provides hot water more quickly.

Electric tankless water heaters eliminate Stand-by Loss and Cycling Loss. They only heat the hot water as demanded, reducing water heating costs by up to 60%.

There are 3 pieces of information necessary to determine what size tankless water heater is right for you:

  • Watts – the amount of energy necessary to heat a given demand.
  • Temperature Rise – The difference between the inlet water temperature and the set outlet temperature.
  • Flow Rate – Measure in Gallons Per Minute (GPM) represents the amount of water that will be heated at one time.

How electric tankless saves energy

Traditional storage water heaters have a set amount of water that is kept heated to a set temperature so that is always ready to go. When the stored water reaches its set temperature, the thermostats disconnect power going to the element and the unit stops consuming energy. The water then loses temperature, a principle known as Stand-by Loss. The elements will then turn on again and consume energy to heat water back to the set temperature.

When hot water is used, the water storage is refilled with cooler, ground water that needs to be reheated. This causes further heat loss, or Cycling Loss, requiring the elements to turn on and consume energy.

Stand-by loss and Cycling Loss are responsible for up to 20% of energy loss.

EcoSmart electric tankless heaters save energy by only activating when water is flowing through the system, so that there is no stand-by loss or cycling loss.


Patented Self Modulating Technology

Activation and energy consumption control refer to the minimum flow rate at which the unit activates, how it activates, either by flow switch or flow sensor, and how it controls the amount of energy it consumes.

All EcoSmart electric tankless water heaters activate at .25 gpm and, with the exception of the POU models, operate on Flow Sensor technology. The flow sensor modulates the energy consumption to meet the demand for hot water. Flow switch activation, on the other hand, activates the unit by either switching power on or off to the heating elements instead of modulating.

Other tankless water heaters in the market today operate via a flow switch. When hot water is demanded the flow switch is pushed or moved via the water flow and activates the unit. Most flow switches are designed to activate the units at flow rates between ¾ to 1 GPM. This becomes a problem since in areas of low water pressure the units might not activate or in the case of mixing cold water to lower the outlet temperature the hot water flow is reduced and if reduced under the activation flow the unit turns off thereby producing a cold water rush.

Temperature Control

All EcoSmart electric tankless water heaters, except POU models, come with a digital display showing the outlet water temperature setting. The digital temperature control can be adjusted in increments of 1ºF and ranges from 80º to 140º F.

The temperature controls allow you to set it and forget it.

Heat Exchangers & Elements

Heat exchangers and elements are the components the water passes through to heat up. The elements heat the water and the exchangers encase the elements.

All EcoSmart electric tankless water heaters come with standard Emerson Electric heating elements made of either copper or stainless steel. These elements come with a brass top to prevent electrolysis and easily screw in and out of the top of the exchangers, which are also made of copper and stainless steel depending on the model.

Most other tankless water heaters on the market use uncommon or coiled heating elements that can only be found with the manufacturer.  If an element burns out for any reason then the entire heating module must be removed to service the heater or the heater must be replaced entirely.  These elements are often encased in a poly-plastic exchanger which increases heat dissipation and decreases energy efficiency.  EcoSmart tankless water heaters have standard, reliable, easily serviceable elements and heat exchangers that provide 99.8% energy efficiency


Overall, design considers the simplicity of the unit and how all the components integrate together to promote functionality, durability and serviceability. All EcoSmart electric tankless water heaters come with an automatically resettable thermostat as opposed to a manually resettable thermostat. The integration of all components and quick connections are designed to promote simplicity for the installer and the user.

Most other tankless water heaters on the market have overly complicated designs and uncommon parts that are difficult to service.
