On Demand Hot Water Pump.

Many homeowners experience a long wait for hot water to reach their shower or bathroom faucets that are not located near to the hot water heater. This delay is caused by water that has cooled down while standing in the hot water line pipes. While the homeowner waits, the shower or faucet is left open, and the water running, which simply goes down the drain, thereby wasting the cost of the water as well as the sewer cost of removing the water.

On demand Hot Water Pump

The solution is an On Demand Hot Water Pump.

An On demand, Hot Water Pump drives a recirculation system, which is activated as needed by a homeowner, to pull hot water from the water heater, while simultaneously sending cooled-off water from the hot-water lines back to the water heater.

In addition to having the convenience of near-instantaneous hot water, the system conserves water and uses little energy.

How does an On Demand Hot Water Pump work?

After you push a button, or activate the motion sensor, while you are preparing to shower, your On demand Hot Water Pump system will swiftly and briefly pull hot water from the water heater to your fixture as follows:

  • The On demand Hot Water Pump is connected to the hot water supply line at the furthest fixture from the water heater, and then connected to the cold water supply line.
  • The On demand Hot Water Pump uses the cold water supply line as the return loop to the water heater.
  • A motion sensor or activation button is installed at any plumbing fixture to wirelessly activate the On demand Hot Water Pump.
  • The temperature sensor in the On demand Hot Water Pump shuts it off when hot water reaches it.

The On demand Hot Water Pump can work with conventional or thankless water heaters.

What are some benefits of an On Demand Hot Water Pump?

  • Saves Time. No more waiting for hot water. With an On demand Hot Water Pump System, hot water takes about 15-20 seconds for hot water to reach your water fixture after you activate the system. During this time, you can engage in your normal routine, without running the water.
  • Saves Water. The Department of Energy estimates that 3,600 to 12,000 gallons of water per year can be saved by the typical household of four with four points of hot water use.
  • Saves Municipal Energy Use. When energy is used to treat municipal water, pump it to households, and then treat wastewater are factored in, the Department of Energy estimates that energy savings per the same household of four range from 800 to 1,600 kilowatt-hours per year.

Will an On Demand Hot Water Pump save you water, energy and money?

Whether it will or not depends on the location of your hot water heater(s) in relation to the furthest shower and faucets, the design, internal diameter and insulation of the plumbing lines, the number of occupants, their habits, the thermostat settings and many other factors.
