After installation I ran the hot water at both bathrooms and the kitchen and there was plenty of hot water. There are very specific venting parts that do not come with the Tankless Water Heater. Those parts can be an additional $250 depending on how you vent the heater. If you vent through the roof, you will also have to buy a roof flange, because the venting pipes are larger than the existing pipes. When they install the new flange, you will have to replace some shingles. The over all installation I thought would be just put it on the wall and connect the gas and water pipes ended up being quite a bit more than originally anticipated.

Rinnai Review
We moved into our new house in Oct'21. Our tankless Rinnai water heater (located in crawl space) works fast & decently when the source of the faucet is closest to the Rinnai tank (e.g. bathroom & shower). However, when the faucet is far away from the tank, we didn't get any hot water for over 2-3 minutes (e.g. our kitchen sink), and ended up installing a small 2.5-gallon Bosch hot water tank under our sink to get instantaneous hot water for the kitchen sink. So be sure that your tankless Rinnai water heater is large enough for your house (ours is too small), and that faucets farthest from the tank may take a while (e.g. minutes) to get warm/hot water.

    Endless hot water(eventually)
    I purchased the tankless hot water heater approx. 1 year ago. I am pleased with the performance of it so far. But the initial switch over was a big adjustment to get use to not having hot water instantly. Now that we have adjusted, we could not be happier! No more cold showers!

        Tankless hot water heater review
        Works great and never fails to heat water for as much as you need. On-demand supply means not having to use natural gas to keep a tank heated and ultimately saves energy and money.

          Heater always turns on when tap opened irrespectiv
          Hot water comes very late. It’s makes noise intermittently without any tap opened. Always turns on if I open cold water as well. I think some settings need to be adjusted.

            Rinnai unit produces hot water as long as you don'
            My home builder (Taylor Morrison) installed the unit in my attic. The problem is this - I like to set the water temp to 140 but when I do, the unit overheats and shuts down. Never had a problem like this with the old stlye hot water heater and am not sure I'll continue with tankless.

              New Home & New Tankless Water Heater
              My water heater has a circulating pump. The pump system is wifi and I have an app on my phone. I worked with tech support to get is all set up. Very helpful and sort of easy. The system works very well and I am happy with it. My tankless WH is in the garage and we live on the 3rd floor. W/O the pump it took almost six minutes, now it's only about 15 seconds.

                We are not getting consistent hot water.
                We have been in our new house since April. Occasionally when washing our dishes, the water will go cool ( only for a very short period of time ) ??

                  Hot water
                  3 months I've owned a Noritz before but it was recirculation type and I miss that on this model. This was a new build with no options to upgrade. Hot water does take a while without recirculation feature. Over all nice product.
