Recirculation pumps are an important part of hot water supply in your home or business, even though they may not be included in a tankless or conventional water heater.

You will need to have an additional pump and the dedicated line for units without recirculation pumps. You will also need a timer to turn on the recirculation pump with the traditional unit. It is expensive and can be very costly.

Different types of Recirculation Pumps

There’s three types of recirculation pumps.

  • Pumps for basic recirculation
  • Pumps for recirculation on-demand
  • Temperature and time pumps

Pumps for basic recirculation

This is the simplest form of a basic recirculation pumps. It moves water through pipes and water heaters.

This option is for those who don’t have any specific needs but still want the recirculation pumps to their water heater.

Pumps on-demand

Only hot water is available to on-demand pumps when a person turns on the hot water supply in a shower, bathtub, or sink.

The on-demand pump will keep pushing hot water from the heater until it is switched off or the temperature is reached.

This option is recommended by our plumbers for those who don’t need hot water often but want to cut down on water costs.

Temperature and time pumps

Finally, temperature and time recirculation pumps are set to turn on at a particular time to pump water up until it reaches a specified temperature. The pump operates only when it is needed. This can help you save money and still provide hot water. This is a great option for anyone who is looking to cut down on water costs.
