SK (Aqua ) Submittal The SK, named Aqua, is a premix gas-fired condensing hot water heater that complies with ANSI Z.0. SA. Gas-fired water heaters. The Aqua, is equipped with a low-tech stainless steel heat exchanger that consists of a single tube coil with a diameter of mm. This larger coil tube reduces the pressure drop across the heat exchanger, and prevents deis/limestone deposits and makes it much easier on maintenance. The Aqua features a :0 air/gas modulation which is important for energy savings and important in providing a wide range of desired flow rates and temperatures.
