DESCRIPTIONS
Brand New AQUAH Premium direct vent natural gas tankless water heater with free stainless steel vent pipe;
Compact, highly efficient and ideal for indoor use with thermal efficiency of >=88%;
Water temperature, once set, will remain constant regardless of fluctuations of water/gas flow;
