Review: Definitivamente el mejor calentador de agua que he tenido, silencioso, ahorrativo, calienta el agua excelente, definitivamente lo recomiendo, de hecho ya lo he recomendado a varios de mis clientes, soy arquitecto y estoy feliz con mi calentador
Review: Previously, I had an old Electric water heater. I can't complain, it lasted 17 years with minimal maintenance. Decided to look into a tankless due to the electric costs being so high. I purchased an outdoor unit, since I didn't have any previous vents to the outside. It is super quiet and sometimes I have to go outside to make sure it is working when the hot water is on. The new Rinnai tankless has only been installed for a month but works great! Even survived the cold Northern Indiana winter so far. The heater has sensors to keep the pipes warm within the unit but be sure to protect the outside piping going to the unit from the cold. Hot water everywhere in the house and at the same time. Never installed a tankless water heater before, but with many videos on you-tube about Rinnai water heaters, made it easy and answered all the questions to know what to do. Two settings, Factory default is 120F, tested with a temperature gun and was getting 117F at the faucet. 140F degree setting is producing 133-135F at the faucet. If it saves on electric cost, it should pay for itself within a year. Should have done this years ago. Definitely has exceeded my expectations so far!
