Frequent Asked Questions


What is a tankless water heater?
A tankless water heater has no storage tank and is activated only when there is a demand for hot water.  A tank heater consumes energy 24 hours a day whether you use it or not.  Tankless water heaters also provide unlimited hot water as there is not stored capacity to run out.  Because there is no storage, the physical size of a tankless heater is much smaller allowing you to install the heater much closer to the application. 

What is the tankless advantage?

  1. Compact size – can be installed at point of use, saving space and providing hot water instantly.
  2. Ruggedly designed for decades of reliable operation
  3. Saves money – only consumes energy when hot water is needed for up to 50% savings
  4. Endless hot water – never run out of hot water again.

Will hard water affect a tankless Eemax water heater?

How do I make sure I have the right Eemax tankless water heater for my application?
