Types Of Best Hot Water Recirculating Pumps

Hot water recirculation systems are closed systems although there is some room for variation under the closed system umbrella. Some are simply on all the time while others will automatically activate when the water in the system reaches a certain temperature and still others can be programmed to turn the device off when you anticipate that no one will be home.

  • The temperature activated pump – This type of recirculation pump monitors the temperature of the water in the system and when it falls below a certain point – say for instance 80° Fahrenheit – the pump is activated. Conversely if the water temperature rises above a certain point – let’s say 95° Fahrenheit – the system will shut down so as not to waste energy. These types of hot water recirculation pumps are very popular.
  • The time activated pump – This is a programmable pump that turns the pump off automatically for period of time based on your settings. A great idea if the house is typically empty during the day when everyone is at work and/or school. Just program the pump to shut down at 10 am for instance and to restart automatically an hour or so before you or others typically get home. This way you have hot water waiting for you but you don’t have to pay to have the pump in operational mode all day long.
  • The ‘always on’ pump – These are usually the least expensive recirculation pumps and that makes sense. After all, features cost money to develop and implement. It must be said though that the always-on pump is fast going the way of the dinosaur and within a few years will likely be phased out altogether.

How to Install a Best Hot Water Recirculating Pump

Here are the 11 steps involved in a typical installation of a Grundfos-type hot water recirculator:

  1. Shut off the cold water pipe running into the water heater. It is usually located at the top of the heater. Open a hot water faucet somewhere to make sure the flow has stopped.
  2. Disconnect the flexible hot water supply line where it attaches to the water heater. Be careful though. Residual water is bound to spill out, so have a rag handy to catch it.
  3. If you have a programmable pump set up the times you want it to turn on and off now. It will be a bit more difficult to do so after the pump is installed.
  4. Now screw the recirculation pump into the hot side of the water heater where the flexible hose was. Be sure the timer face is visible when the pump is tightened down.
  5. Connect the loose end of the flexible line to the ‘out’ valve on the recirculation pump and tighten it down securely. Then reopen the cold water valve you closed earlier.
  6. Go now to the sink in the house that is furthest away from the hot water heater. Shut off the water supply to both faucets using the valves under the sink.
  7. Screw the water supply tubes hanging from the sink onto the 2 outlets on top of the check valve. The hot line should be to the left and the cold to the right.
  8. Connect the 2 tubes on the bottom of the check valve to the valves on the sink’s water supply lines above the shut off valves. Make sure to attach hot to hot and cold to cold.
  9. Mount the check valve to the wall under the sink in a way that does not create crimps in any of the lines. There will be holes on the check valve to accept mounting screws.
  10. Turn the water back on to both the hot and cold lines. Check for leaks and tighten any connections as necessary. Then run the water until all the air is out of the lines.
  11. Once you are sure the check valve is properly installed return to the hot water heater and plug in the hot water recirculating pump.

Pro and Cons of  Recirculating Pump

In the interest of providing both sides of the issue here are the pros and cons of installing a hot water recirculation pump in your home.

Pros

  • Hot water on demand – Even those not particularly concerned about water conservation can appreciate the difference having hot water on demand will make. No more waiting around for the water to heat up.
  • Smaller water bills – It’s estimated that 10-15% of the water we pay for is the water that comes out of the faucet or shower head and goes straight into the drain while we’re waiting for the water to heat up. End the madness with a hot water recirculation pump.
  • They’re affordable and easy to install – Installing one of these pumps typically takes a couple of hours. Also, a recirculation pump will cost about the same as a pair of high-end athletic shoes and last a lot longer while improving your life a lot more.
  • They’re adaptable – Most recirculation pumps are compatible with most plumbing systems found in today’s houses. Even older homes.
  • No work permit required – You can install the pump yourself on your own time without having to apply for a construction permit.
  • DIY – You can do this type of installation yourself without any special equipment or training. You just need to be careful and methodical and not try and rush through the process.

Cons

It’s hard to find fault with this type of device but we’ll give it a try.

  • It will cost money to run – Some hot water recirculating pumps will ignore this fact. But it’s true and it’s why you should look into a programmable pump that will automatically shut off at certain times.
  • Cold water delay – This type of system may cause a delay in the delivery of cold water. If it does occur it should not be serious.
  • Initial cost – The pumps reviewed above average about $200 each. That’s not enough to break most people’s bank, but it is $200.

Wrapping Up

The best hot water recirculation pumps can transform your home from a water waster to a water saver and add convenience and speed to your daily routines. You’ll save money, time and aggravation and increase the bottom line value of your home at the same time. We hope you found these best hot water recirculating pump reviews and buyer’s guide helpful.
