Questions & Answers

Q:What size of gas pipe it need
by|Apr 6, 2024
1 Answer
Answer This Question

A:  Hi Pulido, please work with a technician that is certified to size gas appliances. There are quite a few things that you have to factor, included BTU load for all appliances in the home, distance from the meter, material used on your gas line and distance from meter to your tankless. Along with a manometer to calibrate the product. Gas sizing is very unique and has to be sized by your application.

          Simply Incredible!
          My wife and I are so extremwly happy with our Rinnai 11 GPM Tankless Water Heater. It has a recirculater built in so the water is hot immediately. We can take 3 showers at the same time with zero hot water issues now. We are so happy with this water heater! Goodbye to my irritating electric heating tank. I highly recommend that you all switch over to tankless.

            Best addition to my house in 2023
            The company offered a High efficiency version of the Rinnai I purchased. I purchased a Super High Efficiency model, the difference being that the high efficiency model expels unused gas out to the atmosphere, whereas the Super High Efficiency model recirculated the exhaust gas back to be reheated...Love IT !!!!

              Sadly I am not able to give the Rinnai RSC199ip a TEN STARS rating! This is an OUTSTANDING Water Heater and the Rinnai support is the best I have ever experienced! I installed the Thermal Bypass valve at the water distribution manifold which has made hot water available at all fixtures in less than ten seconds! I also installed a new Water Softener, UV Light and had the Well Pump replaced. Of those systems the Rinnai Water was the easiest of the the systems to install! I do not expect to ever need another water heater in my lifetime but I WILL DEMAND a Rinnai if i ever do!

              I am a code official and I had a flood in my home from a tank water heater. I jumped on the idea of moving my new water heater outside where it could cause no more damage. I am pleased with the quality and instant hot water produced. It's efficiency exceeds the other units in comparison. I love this tankless heater.
