“Quiet and Efficient”

I have had this tankless for about 2 months. I like the higher efficiency from this condensing unit compared to my previous one (not Rinnai). This one is also much quieter. As with the previous unit, I have this mounted on the outside of the house which avoids PVC venting.

“Super efficient way to heat household water. ”

This unit is much quieter than my previous heater. The quality is top notch. I wish it had a built in recirculating pump, and I wish it had wireless buttons to place around the house to start the recirculating.

“Rinnai eleminated the controller prices have not been reduced even though Rinnai claiming it has. $150 additional for Wi-Fi or controller is too much, wifi also has many problems and doesn't work always. ”

Rinnai needs to decide either sell through Lowe's or through contractors, both won't work.

The water is hot right away, even when my son wants a really hot shower and turns the temp up. It is easy to turn up, then back down to the temp I like. I have been in my new home about 2 months and my gas bill is less then half.
