Hi : When your unit pumps the cold water back, how does the pumped water
end up in the hot water tank, and not going back to the "main" cold water
supply. ?
Thanks
ANSWER:
Mr. S,
The pump inlet is connected to the hot water pipe which connects to the water heater outlet. The pump outlet is connected to a cold water pipe which in turn is connected to the water heater inlet. A big loop of pipe into and out of the water heater with a pump in the middle.
In order to pump water out of the water heater water must flow into the heater at the same time. The pump is pushing water into the cold water pipe, but since there is no place for it to go except back into the water heater that is where it goes.
You could turn the water main off and the system would function just the same. Water flows where there is a pressure difference and that is created by the pump and has nothing to do with the water main.
Hope that helps.

I am interested in your product, but have two questions regarding the
details of operation.
1) It states that the pump shuts off after the temperature has increased
between 3 and 12 degrees. During a long day away from home, or even
overnight, I would expect the hot water line to cool towards the ambient
air temperature. If this is 70 degrees or even lower on a cold day, how
will I ever get hot water without re-starting the pump several times?
2) It also states that the pump is locked out when the water temp reaches
96 degrees. This seems low, as my hot water tank is set around 120. What
is the reason for the value of 96 degrees?
ANSWER:
Mr. M,
The pump shuts off when it senses an increase in temperature.
There is a time delay when you measure temperature due to time constants involved with getting the heat to travel from the water to the brass housing and from brass housing into the integrated circuit temperature sensor.
If the water in the pipes is at ambient temperature... say 68 degrees... and you push the button to start the chilipepper, the pump comes on, and when the pumps senses an increase in temperature it means the hot water is arriving.
If you waited till the temperature sensor reached 120, by the time the pump shut off there would be a lot of hot water in the cold water pipes.
So no matter how cold your water cools down to it doesn't affect your ability to get hot water.
If however your pipes didn't cool down, then you would have a problem with getting hot water with the Chilipepper.
Hope that makes sense.
The 96 degree lockout temperature was picked by IAPMO (International Association of Plumbing and Mechanical Officials) as the lock-out temperature for hot water demand systems.
Would not have been our first choice.
However, if the water at the fixture is 96 degrees, you most likely very recently used hot water, and it should get there pretty quickly since the pipes won't be cold and suck the heat out of the water as it travels.
Hope I helped... feel free to keep asking questions, and thanks for your interest in our product.

We are installing a Noritz 751 Series Residential Tankless Water Heater
(LP GAS) It is an outside unit. I was recommended the ACT/Metlund Hot
Water D'MAND or Taco D'MAND. I found your company while doing research on
hot water pumps and am impressed with the price of the Chilipepper unit.
Just wanted to make sure your product will work with the Noritz 751.
ANSWER:
S,
Yep, the Chilipepper will work with the Noritz 751, and every other tankless water heater ever made.
Thanks for choosing the Chilipepper!
