How do you get hot water from a recirculating pump?

Quote from the video:
Quote from Youtube video: Now open a hot water faucet preferably a tub faucet elsewhere in your home in order to drain out all of the hot water. After it stops flowing leave the faucet in the on position until.

How does a hot water return line work?





This system creates a loop from the water heater to the faucet and back again. The unused hot water is drawn back through this loop by the pump, so when you turn on your hot water faucets, you get hot water quickly. Water is not left in the pipes to get cold and you waste less water because you don’t have to wait.

Does hot water need a return line?

Not every domestic hot water recirculation system requires a return line. For residential and light commercial applications, there is another way to save water and maintain hot water at the last fixture.

How do I know if my hot water recirculating pump is working?

If the circulator pump is on the RETURN side of the heating piping loop (the usual and better location) then you can feel the pipe at the circulator pump – doesn’t matter which side – in or out flow – since if the pump is running the pipe will get warm, then hot if it is successfully moving hot water out of the boiler …

How do you make a hot water circulation loop?

Quote from the video:
Quote from Youtube video: And it's working really well what we've done obviously the heater runs a little bit more often you're trading using less water for using more gas everything's a trade-off. But.

Are recirculating pumps bad for pipes?





High velocity due to an oversized pump is the number-one cause of pinhole leaks in recirculation pipes. In addition, when the city water company adds chlorine to the water, it becomes worse. Chlorine is a disinfectant added to water to kill bacteria. However, it is kryptonite to piping—all kinds of piping.

What is a secondary return hot water?

Secondary hot water returns are generally used in domestic hot water applications where the point of usage (i.e. taps) are a distance away from the hot water cylinder. They are used to remove the need to draw off a large quantity of cool water, ( left in the pipe run), before hot water actually reaches the tap.

Why is my recirculating pump not working?

Circulator pumps can stop working for several reasons: a blown fuse, bad wiring or a dead motor. Troubleshooting the possible causes in a systematic manner ensures you can find the reason your circulator pump isn’t working so you can get it back up and running as soon as possible.

How do you install a dedicated hot water return line?

Run a single 1/2″ line back from the end of each hot water branch until it gets back to the middle. Join the two 1/2″ lines to a single 3/4″ line back to your cold water input to the water heater. Install a circulating pump with a built in check valve in the line to prevent reverse flow.

How long does it take to get hot water with a recirculating pump?



The wait for hot water can be affected by several factors such as distance, pipe size, number of joints in the pipes, etc. Homes with WaterQuick Standard or WaterQuick Tankless typically get hot water in 30 seconds to 45 seconds.

Should my circulator pump be hot?

A: Circulator pumps are generally used to circulate hot water. The temperature of the pumped medium is transferred to the pump, and it is normal for the pump’s surface to be warm or even hot.

How do you know if you have a bad circulator?

There are a few tell-tale signs that indicate your circulator pump system isn’t working correctly. You may notice: The water flow pipe isn’t hot despite the pump running. A water leak coming from the pump.

How do you bleed a circulating pump?

  1. Step 1 – Turn off the power. …
  2. Step 2 – Protect against water damage. …
  3. Step 3 – Turn off the water at the shut-off and gat valve. …
  4. Step 4 – Slowly remove the pump bleed screw. …
  5. Step 5 – Mop up all the water that trickles out of the pump. …
  6. Step 6 – Screw the bleed screw back into place. …
  7. Step 7 – Turn on the power.
  8. Do circulating pumps run continuously?



    While the system is capable of running continuously, it doesn’t always do this. Most hot water recirculating pumps come with sensors or timers to regulate operation. Sensors can detect the temperature of the hot water in the pipe, only running the recirculation pump when the temperature drops below a specified level.

    How long do circulator pumps last?

    5 to 10 years

    A typical Taco circulator pump usually last from 5 to 10 years unless leaks are left unchecked.

    How much should it cost to replace a circulator pump?

    Replacing a failed circulator pump can cost as little as $400 or as much as $750 or more for the parts and labor at the time of publication. Cost of just the circulator pump itself falls in the range of $100 to $300 depending on the model your system needs.

    What size circulating pump do I need?



    1 GPM = 10,000 BTU/hr, meaning that for every 10,000 BTU’s of heat load the circulator must output a 1 gallon per minute flow. Assuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop.

    Where do you put the circulator pump on a boiler?

    Locating the Circulator Pump on the Boiler Return or “cold” or “inlet” side. On the boiler return or inlet side: most but not all residential heating boilers and probably most commercial heating boilers mount the circulator pump on the return or inlet side of the heating boiler.

    Should a circulation pump be on the flow or return?

    The best place for the pump(s) is still on the flow side. This keeps the bulk of the system under positive pressure from a combination of the pressure imposed by the system water connection, and then when the pump is running, the pressure provided by the pump.

    Does circulating pump go on flow or return?

    Yes that can happen but the pump will only be on when the water is hot enough for the circuit, also you may find the cylinder will take the heat and return it to the boiler if for example the flow and return are in 1″ but the branches to rads are reduced to 3/4 and 1/2″.
