Metlund D'mand S-02T Circulating Pump
and the
Chilipepper CP6000 - Water Conservation Products Compared
Metlund D'Mand system pump modelS-02T , compared to the Chilipepper CP6000 hot water demand pump. The author is the inventor of both water conservation products.
Hot Water Demand Systems are Water Conservation Products
Metlund S-02T D'mand System
The Metlund S-02T Series D’MAND® System is a
water conservation product known as a "Demand"
type hot water delivery system, meaning that the hot water does not get pumped
to your fixtures unless you "demand" it by pushing a button or activating the
system in some other way.
The pump is located at a fixture such as under
the bathroom sink or under the kitchen sink. Typically you would want to locate
it at the end of a main hot water run that supplies other fixtures as well so
you can use one pump for several fixtures. It depends of course, on how your
home was plumbed.
When the pump senses a sudden increase in
temperature it knows the hot water is arriving and it shuts off so the hot water
does not get into the cold water line. The Metlund pumps turn off when they
sense a 3° increase in temperature. Now you have hot water instantly at the
fixture and anywhere else plumbed off the main line.
According to Metlund, the S-02T models are designed for use in large homes or
commercial buildings where the distance from the water heater to the farthest
fixture is greater than 100 feet. They are compatible with tankless water
heaters.
The pump has a maximum pressure of about 13 PSI
and a 1/8 horsepower motor.
The S02T model weighs 16 lbs. Dimensions are 16"
wide, 9 deep, and 6½" tall. The motor used for the S-02T is a Taco Model 0011
Circulator pump.
Installation of the S-02T requires full 1/2
plumbing connections, normally requiring the removal of the angle stops under
the sink to T into the piping. This is because the pump does not develop
enough pressure to overcome the pressure drop that would occur in the small
openings in fixture supply hoses.
The prices listed are from Metlund's website.
S-02T-PF Kit retails for about $797.50, and comes with
flanges, two copper “T” compression fittings, and two stainless steel flex-lines
for easy installation.
S-02T-PF-R Kit ($852.55) Same as S-02T-PF plus one remote control package.
The Chilipepper Water Conservation Product
The CP6000 is also a water conservation product and a demand system very similar to the Metlund
D'mand System. The major differences include a much more powerful
motor...1/3 horsepower, a much higher maximum pump pressure...50 PSI, and an
adjustable shut off sensing temperature. The range is 3° to 12°, which allows
you to fine tune the "hotness" of the delivered water when the pump shuts off.
The high rpm powerful motor makes enough noise that you can hear
it run. Since you can hear it run you can hear it shut off and you then know
it's time to turn on the hot water.
Connection to the plumbing is done with the same type of supply
hoses as most of today's homes. The water supply to the house does not
need to be turned off. You just shut off the angle stops under the sink,
connect up the hoses, and turn the valves back on.
The CP6000 weighs 5 pounds, Dimensions are 6" wide, 8-1/4" deep,
and 3-7/8" tall..
The CP6000 works great with any tankless water
heater on the market regardless of brand or model.
The CP6000 retails for $179.99 and comes with a button, a six
foot control wire, and two "T" fittings with adaptors for 1/2" or 3/8" hoses.
The CP6000 can be purchased bundled with a remote
control receiver and transmitter for $215.99.
