New code for us.


Just wondering if any of you professionals have run into the 50 foot to farthest hot water fixture from the hot water heater rule yet? Ohio started requiring you use a circulation system to drop the distance to 50 foot max.

Have any of you guys used heating on a residential application. That is also a way to get around it.

is this part of an energy code or actual IPC
My state of Idaho has it's own code and we stay away from things like energy and ADA stuff. We leave that up to the building officials

Re: New code for us.


607.2 Hot or tempered water supply to fixtures. The developed length of hot or tempered water piping, from the source of hot water to the fixtures that require hot or tempered water, shall not exceed 50 feet (15 240 mm). Recirculating system piping and heat-traced piping shall be considered to be sources of hot or tempered water.
607.2.1 Circulation systems and heat trace systems for maintaining heated water temperature in distribution systems. Automatic circulating hot water system pumps or heat trace shall be arranged to be conveniently turned off, automatically or manually, when the hot water system is not in operation.


New IPC to Ohio we just adopted this in November. Have you ever installed heat trace?

Interesting, never heard of this. Must be energy related, as longer runs = more energy loss to environment. Does this still apply if you insulate the pipes?

Re: New code for us.


From what I read in the commentary the only 2 ways to meet the code is heat trace or a circulation loop. Loops over 100 foot still require insulation.

According to the commentary the reason why this was added was because of the 1/2 gallon of water that was wasted waiting for hot to arrive. Seriously!
