Water Heater Pumps, Hot Water Circulating Systems, Warm water Circulating
Systems, and Hot Water Demand Systems Compared and Reviewed
The following articles involve hot water pumps for water heaters, both storage
tank type heaters and tankless hot water heaters, hot and warm water circulating
systems, and compares and reviews several hot water demand systems.
The Astro Express System,
manufactured by Armstrong is what I refer to as a warm water circulating system.. It's similar to the Grundfos
Comfort system. A typical
recirculating pump is mounted at the outlet
of the water heater so that it pumps hot water out of the water heater and
through the hot water piping to the valves under the sinks.
An Astro Express Valve connects between the hot
cold water lines under each sink. This valve between the hot and
cold water lines creates a “loop” through the hot
water piping, the valve, the cold water pipe, and back
to the water heater.
Metlund D'mand System VS Chilipepper Sales CP6000
The Metlund D'MAND system consists of three models with
different size pumps. The bigger the pump the faster
the hot water flow rate. The S-50 model has the lowest power
and cheapest price at about $339.50. Metlund does
not recommended it for tankless water heaters. Metlund suggests using it for runs of less than 50 feet. You have to use full 1/2" fittings to plumb
in the
pump.
The Laing Autocirc1 warm water circulating system.
The Laing autocirc1 is a cold-water-return warm water circulating system.
It uses the cold water line as a return line and circulates hot water through
the piping keeping the water at the fixture between about 85 to 95 degrees
roughly. Tepid water. The cold water line will no longer be full of
cold water, it will be warmish. To get really hot water you still have to
wait, and if you want really cold water you have to wait then as well, which may
lead to wasting water.
Metlund D'mand S-50T Hot Water D'mand Pump vs. Chilipepper CP6000 Hot Water Pump
Comparing the
Metlund and Chilipepper Hot Water Demand Systems. This article compares the Metlund D'Mand system
model S-50T, to the Chilipepper CP6000.
If you have a tankless water heater that supplies a fixture 50
feet away, the Metlund model S-05T would not be able to produce enough flow to
turn the unit on.
The Metlund S-50T-PF Kit ($356.00) Comes with two ˝" threaded
male adapters two brass “T” compression fittings, two stainless steel
flex-lines, and one hard-wired button.
Watts Premier Recirculating Pump vs. Chilipepper CP6000
The Watts Premier Hot Water System, a comparison between the Watts Premier
hot water pump to the Chilipepper demand pump. The Watts Premier system provides faster hot water but it isn't instant by any means.
The Watts Premier system is a luke-warm water
circulating system. It uses a temperature sensing valve and a continuous
running pump to circulate warm water through the house plumbing.
Hot Water Pumps, Metlund, Grundfos, Autocirc, RedyTemp, Taco, Armstrong,
Chilipepper, and Watts Premier
I will examine the various types of
hot water pumps or systems and you can make a better informed decision about
which pump is best suited for your needs. I'll deal with traditional hot water
recirculating systems, warm water circulating systems like Autocirc, RedtyTemp,
and Watts systems, and hot water demand systems such as Metlund and Chilipepper.
