Question: Hi Robert, thank you for allowing the breakfast interruption last week. It was gracious of you to take the time to answer our questions. We need to install a new water heater, but we are also considering an instant hot system. We have a home that is about 4,000 square feet with our master bedroom upstairs and in the back of the home, so getting hot water to that point is most important to us both in time and volume.
We’ve heard of putting a loop in so that we can have instant hot water. Is this something we can and should consider?

Answer: John, no problem regarding stopping by my table for a question. I’m happy to help. The loop is designed for a multi-dwelling building. Installation is with a half-inch or three-quarter-inch line in which the water constantly circulates.
The volume of water passing through a smaller space, such as a single-family home, allows the microscopic particles to begin to deteriorate the line prematurely and failure of the lines occur. There is also the pump that needs maintenance on a loop, another source of your time and money for maintenance.
You can definitely use a tankless water heater to improve the duration of having hot water — just don’t waste your resources installing a loop line. That’s my best advice. Good luck.
