Reduce Your Hot Water “Wait Time” and Water Bill With a Recirculation System

We’ve all experienced that “lag time” between turning on the water at the sink or shower and waiting for hot water to arrive. Not only is time ticking away, but a lot of water is going to waste. In fact, the U.S. Census Bureau and the Dept. of Energy report that close to 2 million Olympic-sized swimming pools of water are wasted by households every year while waiting for water to heat up.

If you’ve been looking for a smart way to decrease your water bills and wait-time for hot water, installing a hot water recirculation system can be a great place to start. Below we’ll explain what a hot water recirculation system is, how it works, and how it benefits you as a homeowner and the environment.

What is a hot water recirculation system and how does it work?

In short, a hot water recirculation system reduces or completely eliminates your wait time for hot water by changing how your plumbing system behaves.

To explain how a recirculation system works, we’ll first provide a brief explanation of a typical plumbing system, so that you can get a better understanding of how the two differ.

In a typical plumbing system, here’s what happens when you turn on the hot water at a faucet:

  • Water pressure moves hot water from your water heater toward the faucet.
  • That hot water travels through water supply pipes to get to the faucet. These pipes can be chilly and “steal” the warmth from your water. That’s why hot water can become cold by the time it gets to the point of use.
  • Once the pipes have warmed up enough, the water can pass through them without transferring all of its heat away, and hot water will finally arrive at your faucet.

When your plumbing system includes a recirculating pump, hot water circulates in a slow, constant loop through your hot water pipes and water heater. This mode of operation allows the water to always remain hot while requiring relatively little energy. It also means that you have a ready supply of hot water at your fingertips.

What are the benefits of a hot water recirculation system?

When your home is equipped with a hot water recirculation system, your wait time for hot water will be minimal or nonexistent. Not only will you save time, but you can greatly reduce the gallons of wasted water that end up down the drain. This is a significant benefit to both you on your water bill and the environment. Also, consider the energy your local treatment plant uses to treat your water: wasted gallons of treated water amount to wasted energy as well.

I have used green planet a few times. One time was an emergency clog, They were prompt and reasonably priced. Their most recent visit was planned work that was needed on my older home. They were honest and fair, did quality work, answered all my questions, explained my options and gave me sound advice. Green planet is who I call whenever I have a plumbing need. They have always done right by me

Justin rocks. He is incredibly knowledgeable and professional. Keeps it clean and courteous. As a contractor, I have had him and the green planet team rough in and trim out multiple jobs and even work on my own home. Couldn’t recommend a better plumber.

I am SO relieved to have found Green Planet, a plumber I can trust. For years, I had a colleague in my business networking group who did amazing work without bait and switch and ridiculous markup, but he retired. Green Planet came recommended by my next door neighbor. They first did routine maintenance on my rental unit, but this week I called them with a bit of urgency. My water shut off valve snapped off, thankfully when I was not in an emergency, like a burst water pipe. I decided to have them also fix a toilet that on occasion would run for hours and an exterior spigot that was shooting water the wrong direction. Technician arrived within 45 minutes, took a look at everything, and provided a written estimate. He discussed what could go wrong once we removed drywall and fixtures, but made every effort to work diligently to avoid these scenarios. One of the main issues would be the presence of old, corroded, pipes versus modern pex. He had the spigot and toilet fixed quickly and then focused on the main project. Steady lines on the drywall removal help make it easy for me to replace that. Once done, even with a quick parts run to the warehouse, he was wrapped in about 90 minutes with everything looking great. We discussed my aging hot water heater, and options to install an upgraded toilet, so I can make plans to budget those projects down the road. Such a relief to have a company I can trust after some bad experiences with the big brands you see on TV (I see how those types of companies can afford big splashy campaigns).

We had a really great experience with Eddie from Green Planet. We had a shower faucet that was leaking, and also the handle had completely separated from the faucet. Green Planet doesn’t change for an estimate which was really appreciated, and also their estimate to replace the cartridge in the faucet was less than half what other companies had charged us for the same service. We were weighing whether to replace the entire faucet, and he gave us helpful thoughts on that as well. We chose to go with a cartridge replacement because to replace the faucet they would have had to open up a wall. We didn’t have a dry waller in mind. The repair was fast and works great. Thanks so much Green Planet!

It was a pleasure to have Justin and Henry replace our hot water tank and snake out our kitchen sink drain. They were very pleasant and easy to talk to and made sure all questions and concerns were answered. Very rapid response, I called for an estimate and they were here the next day. I approved the work and they were able to start the work the following day. They arrived early and got right to work. They protected all exposed surfaces before starting. When complete they made certain that we understood how to operate the controls on the tank and explained all they did. All at a reasonable cost. We definitely will call Green Planet Plumbing again for any future plumbing needs.
