Why install a Hot Water Pump?

The Watts Instant Hot Water Recirculating System brings convenience and savings to your home, giving you hot water instantly at every faucet or shower when you need it. This unique product connects easily to existing plumbing, saving up to 12,000 gallons of water per year.

How does it work?

This recirculating pump eliminates water waste caused by waiting for water to heat up. The device uses the pump at the water heater and a patented under-sink sensor valve to create a pressure differential. The pressure differential allows the cold and cool water in the hot water supply line to bypass into the cold water supply line at a low volume through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a "no-wait" temperature throughout the home.

Step by Step Installation Guide

Hot Water Pump

Sensor Valve

Valve Kit

Step 1 - Installing the Pump

A pump with a built-in timer mounts directly on the hot water line from the water heater with 3/4" connections.

Step 2 – Installing the Sensor Valve

A patented sensor valve opens when the water on the hot water side cools and pushes the cool water back to the water heater. As the temperature in the hot water line hits 98º, the valve closes.

Step 3 – Installing Sensor Valve Kits

If one section of your home does not receive hot water, you will need to purchase a Watts Sensor Valve Kit for each hot water loop. For best results, the valve should be located at the faucet furthest from the water heater in each loop.

The Only Review You Need To Read
5 Stars
The Only Review You Need To Read
I happened upon the idea of hot water recirculating pumps while looking for a small on demand hot water heater for under my kitchen sink. My home is over 4,000 square feet and has 5 different levels plus a basement. Hot water is supplied via a single gas heater in my basement. The kitchen sink is actually the closest tap to the heater but with mine and my wife's schedule, we are actively using hot water at two different times of the day.My wife and I are both up at 5 am, I get ready for work while my wife works out. In prefer a shower at night so in the morning I'm only preparing my breakfast and packing a lunch. After preparing breakfast and lunch I'd rinse the dishes, the hot water would reach the tap just as I was finishing. I'm out the he door by 6 am at which time my wife is be jumping in the shower. She'd have to let the shower in the master bedroom run for a min or so to get hot. The master bath is above the kitchen.At night I hit the gym on the way home. I'm home around 6 at which point I'd clean up my dishes and make dinner or if my wife cooked I'd eat. My wife gets home from work around 5 pm. I'm in the shower between 8-9 pm and as the saying goes, rinse and repeat.....I've found that I'm constantly waiting for hot water. When my wife and I return home from work, we clean or rinse dishes etc and the water takes time to warm up. As we all know, once the pipes get hot, the subsequent use of hot water within 15-30 mins results in instant hot water. When I move upstairs to my master bath, the cycle repeats, the pipes leading to the shower have to heat up since the bathroom wasn't used since 6 am that morning.Solution, I purchased this unit and installed the valve on the guest bathroom which is on the same level as my master bath and happens to be the farthest from the hot water heater. I set the timer on the pump to run from 4am-10am and 4pm-10pm. I found that hot water wasn't instant at the kitchen or master bathroom but it only took 5 seconds or so for hot water. The guest bathroom has instant hot water at these times and the cold water from the sink comes out like warm for 20-30 seconds.Conclusion: the pump is honestly a no brainer. The only drawback is the sink with the valve won't have instant cold water, instead it will be luke warm for some time. The power consumption is minimal, any worry about cost of operation should first consider the cost of operating a TV or computer va this until which saves literally thousands of gallons of water. As far as energy consumed heating additional water, I would consider this; based on my hot usage, my pump turn on about 1 hr before my wife and I wake up and start using hot water. The hot water heater will trigger startup about 30-60 minutes after the pumpHas started due to the drop in temperature caused by the pump slowly circulating hot water. Once we start using hot water, this of course adds to the demand on the hot water heater what I found is that the hot water heater doesn't start more often, it just runs for a longer period of time. This is a win win because the units waste most of the energy consumed (gas, oil or electric) during startup as the components get up to temperature. Think of it like this, how much has downs your car consume while driving down the highway? Cars are most efficient when traveling down the road in its highest hear at between 60-75 mph. Any faster and the wind resistance takes significantly more effort to overcome. Any slower and the vehicles motor is turning to slow to create enough power to maintain speed or a lower gear is needed which is less efficient. Your hot water heater about 10-20 minutes after startup is like your car cruising down the road as I explained. Now think about when your car is stopped and turned off. To get going your first have to turn the car on then start driving. While excelerating, your car is very inefficient but once up to speed, all is well and it's becomes efficient again. Setting up the timer to turn the pump when you normally use water will usually only extend the runtime of your hot water heater. This results in very little wasted energy but the water savings and impact on our environment from the saved water vs increased fuel consumption is dramatic. If you have a well and septic system as I do, this relieves close to 15% of water consumed from your well which in turn puts less stress on your septic as there is significantly less waste water.Lastly this pump includes one of the thermostatically controlled valves so don't bother purchasing a seperate one unless you have a home with a branched hot water line off the main line. In that case a second valve can be put on that line so you heve instant hot water from all taps.
