In both alternative A or B, the water heating units would be placed in the garage storage room, which immediately presents a different set of concerns as we lose the efficiency that came with the proximity of multiple tankless units throughout the house.
Our main concern in initiating the research into alternative water options had to do with one particular obstacle with the tankless units – Maintenance. Although these are great units, with much to like, we decided to do a little research and look into other water heating options that we could then present to the client. To set the stage better we have a 7,000 square foot custom home for a family of 5 (2 Adults, 3 Teens), with the original intent behind the 3 tankless units being to keep the runs from unit to end user as short as possible and serve 3 zones – 1. We’ve liked and used each of these types of water heaters for different reasons and in different contexts and are continuing to learn not only how well these operate over time, but how well they are meeting the specific needs of the residents they serve.įor this case study, the same three types mentioned above play a role (scroll to the end if you just want a numbers comparison of our three unit choices), starting with three(3!) Rinnai RU98i Tankless units currently slated for the project.
If you’ve been following this blog or my YouTube channel you’ve seen that we’ve reviewed and posted about a Rheem HP-50 Hybrid Heat Pump (and an AirTap ATI 66 ), a Vertex High Efficiency Gas Condensing unit and a Rinnai Tankless unit.
