Do it Yourself: Re: [DIY] Recirculating hot water system

We did not opt for the smaller model but installed the Rheem mid size and it will heat the water st full flow. With this system you are not heating then cooling the water back to usable temp which is both a waste of energy and water.
Another big advantage is that is the wife tuns on the hot or cold water in another part of the house the water at the bath remains constant. No cold dips or hot flashes.

With only hot water flowing to the shower/bath (ie, yousaid added not cold water)
my question is how is the volume of flow without adding cold? Satisfactory? Seems
almost diminished 30-40%..and these old bones love lots of flow...esp here in California
where we take a bath or shower once a month whether or not we need it! hehhe
(and shower with a close friend is now state law!)

FYI, we replace our entire hot water system with a gas
fired
tankless water heater with a remote temperature control
which we
installed in the bathroom. We knew that the
temperature setting for
bathing and the time delay would be too low for normal
kitchen use
so a 6 gallon electric point of use tank was added in
line with the
hot water supply to the kitchen and installed in the
basement
directly under the kitchen sink. I turned the
temperature of the 6
gallon heater up approaching 180 degrees and we leave
the tankless
temperature set on 102 to 104 which is just right for
showering and
bathing. In this way we only heat the water to the
temperature we
want and so never need to add cold water for bathing.
After two
years we would never go back to a tank type system and
having a
continuous supply of warm bath water is much appreciated
when it is
necessary to alleviate the pains of aging on tired old
bones and
joints. I've considered a second point of use tank
for the bathroom
sink, but have not found it necessary.

My second question is about recirculating hot
water systems.
It currently takes a full minute to get hot
water to our
upstairs kitchen sink from the lower area where
the hot water
heater is and since the new half bath is about
20' further on
the line, it would be longer. Our water comes
out of the
ground very cold, and it's not yet real winter
here, and pipes
cool off immediately. The only place we have hot
water
quickly is at the bathroom sink, directly next to
the hot
water heater on the ground level. I was
concerned about
getting hot water to the dishwasher, without it
constantly
kicking into a delay cycle to heat the water -
even with the
pipes insulated they still run through open areas.
They
suggested we could try a booster on the hot water
heater that
would probably work for the sink, not sure about
the
dishwasher. A recirculating system, while more
expensive,
would definitely solve the problem. There was
several hundred
dollars difference in price. He said if the
booster didn't
work he would refund all the labor costs but could
not refund
the actual cost of the booster. We decided to go
ahead with
the recirculating system - but now I'm wondering
about the
cost to operate vs the convenience of having hot
water. The
plumber was very thorough about explaining
everything, options
etc but I hope it wasn't an expense we'll
regret. Although
we've lived in the country almost forever this
is the first
time we've lived where conveniences are so hard
to get and our
"home" wasn't built as a full time residence
so we're facing
more problems. Not as young as we used to be so
have to rely
more on professionals.
