Compare Electric Tankless Water Heaters

There is a huge range of technology current on the market with respect to tankless water heaters. For the consumer, the task of evaluating different technologies can be daunting. We believe that the evaluation of electric tankless water heater technologies can all be boiled down to a few important considerations:

SMART CONTROLLER TECHNOLOGY allows you to set the temperature from 80º to 125º F... once the temperature is set the unit self regulates by measuring the inlet water temperature and flow rate to adjust its energy consumption thereby offering greater savings and the ability to run multiple applications.

• What technology does the heater incorporate to modulate power to the heating elements in accordance with changes in water flow rate and incoming water temperature?
  
  
• What level of technical assistance and warranty support is available?
  
  
• How much does it cost?

Power Modulation Technology

No single factor will impact your day to day experience with your tankless water heater as much as the unlerlying technology that controls the power output of the heating elements. The technology on the market today varies considerably:

• No Flow Modulation / Full on or Full Off - This represents the most crude and basic technology. In this case, the heater only has one power setting and does not compensate in any way for changes in incoming water temperature or pressure. These are unsophisticated models and are prone to many problems in the field. They are not suitable for whole house use.
  
  
• No Flow Modulation / Various Power Settings - This is a slight variation on the above, except that the user can adjust the power output setting of the heater. In applications with consistent flow rates from faucet to faucet on a city water supply with steady pressure, this type of heater can provide a reasonable constant flow of hot water. However, in many cases, lower flow applications will overheat causing the hi-limit temperature sensors to trip frequently causing the water temperature to fluctuate. Water temperatures will also fluctuate when additional faucets are turned on or off during use.
  
  
• Basic Flow Modulation - This type of heater does measure the flow rate of water and will modulate overall power output by turning heating elements on and off. The problem is that most tankless water heaters only have 2 to 4 heating elements, so the range of control is still pretty limited and "stepped" rather than continuous. The result will generally be inconsistent output temperatures at the faucet when flow rate or pressure changes occur.
  
  
• True Flow Modulation / Thermostatically Controlled - This is the most advanced type of electric tankless water heater available. This type of heater constantly measures the water flow rate, and both incoming and outgoing water temperatures to modulate power (amperage) to the heating elements as changes are detected, thereby maintaining a precise output water temperature at the level selected by the homeowner/user.

Why we believe the American Heat tankless water heater is the very best choice on the market today:

1. True Flow Modulation & Thermostatic Control
Set it and forget it! The American Heat tankless water heater features the most advanced temperature control system available in an electric tankless water heater today. It constantly measures the water flow rate and incoming water temperature to modulate power to the heating elements to maintain a precise output temperature as selected by the user. A convenient digital display indicates the temperature setting.

2. Quality Components
The American Heat tankless water heater is made in the USA. The heating chambers are copper and brass. The unit is protected by an attractively-finished, sturdy aluminium case with integrated mounting bracket. Many competitors use inferior plastics to save costs.

3. Industry Leading Lifetime Warranty
The manufacturer, American Tankless Water Heater Corp., offers a lifetime parts warranty on all parts including the heating elements! If your heater ever needs to be repaired, a temporary replacement unit is sent to you while your unit is being fixed so you do not have to endure days or even weeks without hot water.

4. Technical Support
The founder of American tankless water heaters has been in the industry for more than 12 years. He is often referred to as the father of electric tankless water heating in North America and he has personally been resonsible for many of the innovations seen in the industry. The bottom line is that his company knows this business - there is not an application or situation they have not seen before. As an authorized dealer, our fully trained tech support staff are also available to assist you.

5. Price and Value
At the end of the day, price still matters too. As a homeowner or business, you deserve the best value for your dollar. Not only does the American tankless water heater deliver the most advanced technology, top notch quality, industry-leading warranty, and expert technical support, it offers it at a very competitive price. This is especially true when one considers that all American tankless systems are provided with a certified sub-panel and associated breakers (as required by most electrical codes) at no extra cost.
