 There is a huge range of technology currently 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 80 degrees to 125 degrees 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.
POWER MODULATION TECHNOLOGY which controls the power output of the heating elements varies considerably on the market today.
There is the No Flow Modulation/Full on or Full off – These are unsophisticated models and are not suitable for whole house use.
There is the No Flow Modulation/Various Power Settings – These cause the water temperature to fluctuate.
There is only Basic Flow Modulation – These do measure flow rate, but there is inconsistent output temperatures when flow rate or pressure changes occur.
There is True Flow Modulation/Thermostatically controlled – This is the most advanced type to electric tankless water heater available – "The GULFWAVE 2". 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.
