ConceptEver got frustrated waiting for hot water in the morning or before taking a shower?... You are certainly not alone. Anywhere from 2 to 3 gallons of cold and/or warm water is wasted every time a hot water tap is turned on between long unused periods of time, especially in homes (buildings are equipped with re-circulating pumps to minimize this wasteful use of a precious resource - Water).
Grundfos "Comfort" pumps are ideal for hot water re-circulating. Economical and easy to install, these small circulators help save water and energy cost, adding the convenience of instant hot water.
APS Pumps & Motors has stock of these UP circulators especially designed for hot water re-circulating. Available in 9 models for every need and budget.
The models with built in thermostat can be set to stop at a preset liquid temperature. The setting range is 95-150°F. Thermostat function can be by-passed.
Models with a built in timer can be set to start-stop at preset intervals, such as mornings and evenings, when hot water is in most demand and likely to have been 'standing' in the pipes longer, and therefore has cooled off.
By turning the circulator on, that water is returned to the tank for re-heating, while 'fresh' hot water fills the pipes providing instant hot water without any water waste.

The comfort Valve offers another option to return the cold water in the pipes back to the Tank. It is simple to operate and install.
NO RETURN LINE REQUIRED
UNIQUE WET ROTOR DESIGN WHISPER QUIET OPERATION BUILT-IN TIMER AND POWER CORD
COMES COMPLETE WITH PUMP AND VALVE
A return line is installed near the faucet farthest from the water heater. The return line is connected to the UP 15 series pump and flows back to the water heater.
As water slowly cools in the hot water line, the UP 15 series recirculation pump then moves the hot water from the heater throughout the pipe back to the heater, creating a continuous loop of slow-moving warm water. When a faucet is turned on, warm water is instantly available for use with no waste.

Centrifugal Pumps
The CR pump series covers a performance range unmatched by any other pump in its field with pumps suitable for a variety of applications.
From drinking water to high viscosity liquids Grundfos' unique hydraulic design and the new production techniques allow the CR to offer the highest efficiency...a considerable advantage to the operating efficiency of large pumps.
PRODUCT RANGE:
Small CR Pumps (1s-1-3-5)
Large CR Pumps (8-16-32-45-64-90)
Series CRT (Titanium)
APPLICATIONS:
> Industrial & Process Applications
> Irrigation & Agricultural Applications
> Water Supply Applications
INDUSTRIAL & PROCESS APPLICATIONS:
Process water for food, petrochemical, steel and numerous other industries Wash-down, car-washing and cleaning Boiler feed, heating and cooling plants Cooling and lubrication for machine tools Water treatment plants, filtration and reverse osmosis systems Reliable even in Demanding Applications Grundfos CR pumps are designed for trouble-free running where choice of materials is of special importance--even when pumping aggressive liquids such as detergents and solvent solutions.
In the CRN models, all parts coming into contact with the pumped liquid are made from high grade corrosion-resistant stainless steel (316SS). These pumps incorporate several features for handling liquids containing air and particles. High efficiency Industrial applications typically require long operating periods. Grundfos CR pumps are ideally suited for this sort of application due to the very high efficiency ratios of greater than 80%.
