I have to say ,,I had another brand of tankless water heater before ordering this Marey GA16LPETL 4.3 GPM ,,,,The heater I had was noisy and you had to adjust the water input and gas input to arrive at the temp. you wanted,,,,The Marey is like driving a luxuary car...Its quiet ,,,You just set the digital temp,,,,And its great,,,Yes I would recommend this heater,,,And its well priced,,!
