Lemee see if I understand this spam...
It pumps the "cooled down" water in the hot water line back down the
cold water line so that the the hot water line is always filled with hot
water (whenever the unit is "on" per the 24 hour timer or other control
This leads me to ask two questions:
1.If I want to draw a glass of nice cold water to drink, won't I have to
run the cold water (down the drain) until all that warm water which was
been pumped into the cold water line gets pushed out?
2. What about the fuel cost to keep the water in the hot (and cold)
water pipes hot all the time the unit is on? Those pipes usually aren't
insulated, so the thermal energy in the water radiates away and has to
be made up by whatever fuels the water heater.
I'd be suspicious about believing any claims from someone who doesn't
understand basic electrical energy/power units and makes a meaningless
statement like this one (from his web site's FAQs:
How much does it cost to operate?
This unit uses only 14 watts in a 24 hour period if the built-in timer
is not used. If the timer is used, the unit uses even less.
I don't doubt that this device accomplishes it's claimed purpose of
easily converting an existing system to let you get "instant hot water"
in one (or maybe more, depending on the piping layout) room in a home.
Devices like this have been around a long time.
But, I bet the real overall energy costs are a lot higher that this guy
would have you believe.

Yea , the LIAR is hereee again, you wont save a thing, not a
penny in utilities, it will cost you to heat more water.
And his claim of operating costs, well just more crapola con artist
Bull Shit .
The size of that pump at that cost to operate , well very litte GPM.
Just look at that cute little non-commercial quality timer, looks just
like the ones that last me a year. Crap, Lies, Bull Shit and More
Bull Shit from Ready Crap , your friendly Lian Con Man
The dam thing will never give you pay back because your pipes will now
be HEATERS radiating heat into your house which as summer is here will
only increase your Air Conditioner usage and overall gas and electric
Circulator pumps cost money to operate, and waiste energy
The professionals no better...
Purchase a Hot Water Recirculating System from participating dealers

Purchase a crappy , cheap, non commercially built ready BS and receive
a 200 $ increase on your water heater bill Every Year , its the gift
that keeps on giving. Forever, or until the cheaply built crap breaks.
And don't forget it keeps your walls allot warmer even in this 90
degree heat 24-7 so your air conditioner wastes even more energy
trying to cool you down all summer.
Spam SPam SPAm SPAM From lowlife Richard HEELson, the shithead
who cant even spell and has to lie to make a sale. Yea folks a great
deal, pay More to heat your water, heat your pipes and your house and
pay more to cool it.
They might well warn that this is a mixed blessing,
with less water usage and more energy usage.
Not much, with a motion sensor instead of a timer. Taco's developing one
like that. $295 doesn't seem like a bad price for this RedyTemp package
with all the hoses. Perhaps they can offer it cheaper with a sound sensor
but no timer. We might make something like this from standard parts like
Grainger's $18 4PC96 aquastat and their $103 5P429 pump in series with
a $77 3A434 solenoid and an $18 3A440 coil.
The RedyTemp site says it saves gas, ie water heating energy, because
it sends warmed vs cold water back to the water heater. This seems false,
since the hot water loses heat to house air on the way back. A seperate
recirc line back to the water heater would be more efficient. Without that,
you might walk into the kitchen and trigger the motion sensor and pump
some hot water into the cold line, then open the cold faucet and have to
wait for the water to get cold again, which is a waste of time and energy.
