I'm looking into installing another bathroom (toilet, 2 sinks, shower, and
tub) that will be about 55 feet horizontally, and 8 feet vertically, from
my
water heater (I've got a 60-gallon indirect water heater). Is that too far
to run a hot water line? If it is, any suggestions?

Thanks in advance,

Mike Shapp


The biggest problem will be waiting for hot water. The smaller the pipe
the faster you get hot water ( less volume) Code would probably call for a
3/4" feed, but with all these low flow fixtures 1/2" would most likely work.
As mentioned a hot water circulating system would be ideal. You could run a
3/4" for the feed a 1/2" for return. You do not have to pipe right to the
fixtures but the closer the better. You will want to insulate the pipe. The
circulating pump is usually at the water tank. it also a good idea to
install a timer so it is not constantly running. You could run the return
line ( it would be a good idea) and then see if you really need a circ.
pump if so add later. It might be feasible to do all the hot waters in the
house while your at it.
