Product Description

The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The pump is characterized by ceramic shaft and radial bearings, carbon axial bearing, stainless steel rotor can and bearing plate, corrosion-resistant impeller, composite, PES, and cast iron pump housing. The motor is a 1-phase motor. No additional motor protection is required.

From the Manufacturer

Grundfos UPS15-58FC circulator pump (Grundfos# 59896341) incorporates a cast iron housing, three speed motor (Low/Med/High) and a built-in, removable check valve. Grundfos UPS15-58FC is among the most popular and most versatile circulator pump models on the market. Pump’s performance parameters cover nearly all traditional heating applications – from radiant and baseboards, to fan coils and zoning and many others. 3 speeds allow to set up the circulator pump in a way, that matches the system’s requirements, while wet rotor design allows it to be virtually silent while operating.

Product Description

The auto circ pump is installed under the sink or faucet farthest from the water heater – where hot water usually takes the longest amount of time to arrive. A built-in temperature sensor automatically turns the autocirc pump on when the water temperature in the hot water supply line cools down to 85º F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater. The autocirc pump turns off automatically when the hot water supply line to the faucet reaches a temperature of 95º F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. When the pump is automatically turned off by the built-in thermostat, an auto closure device prevents hot or cold water from mixing in either supply line. Another beneficial feature is that hot water will also be instantly available at all other faucets in the supply line between the water heater and the faucet where the autocirc pump is installed. Does not require a return line. Requires only 14 watts of power. Packaged complete with a 6 ft. long power cord. Requires only one pump and one installation for all fixtures on the hot water plumbing line. Has built-in fixed thermostat. Has a built-in 24 hour timer which allows the selection of system operating periods to suit family usage. Saves the average family of four up to 17,000 gallons of water annually.. Long lasting, silent operation. Saves energy, money, water and pays for itself in a short period of time (see additional images for energy saving chart). No shaft, no seal. Maintenance free without blockage. Single bearing design. Resistant to scale build up.

From the Manufacturer

The Laing Pump is installed under the sink or faucet farthest from the water heater – where hot water usually takes the longest amount of time to arrive. A built-in temperature sensor automatically turns the pump on when the water temperature in the hot water supply line cools down to 77º F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater. The Laing pump turns off automatically when the hot water supply line to the faucet reaches 91º F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. When the pump is automatically turned off by the built-in thermostat, an auto closure device prevents hot or cold water from mixing in either supply line.The product should be installed by a licensed professional.

The patented SmartPlug lets you upgrade any existing hot water recirculation pump with a power cord to “Smart” operation. Simply connect the SmartPlug to any 110V power outlet then plug the circulator power cord into the SmartPlug. Using a sensor that mounts to the hot water supply pipe, the SmartPlug will record the daily hot water usage pattern in a home and adjust the circulator run time automatically. Hot water will always be available when needed. No Programming, Timers or Aquastats Required • Sensor Included • U.S. Patent #8,594,853 and #9,207,682
