AquaStar Design Features
|
|
The features list is long
The AquaStar is
designed to last a lifetime. The quality of the AquaStar begins with this
inside story: all water parts are solid copper or solid brass. The unit is
constructed with stainless steel and aluminum. Unlike tank heaters, every
part is replaceable or recyclable. Properly maintained, this may be the
last water heater you ever buy.
