Watts 500800 Premier Review


The Watts system is equipped with a 24-hour dual setting timer, which is intended to conserve energy as it operates only when necessary. Whenever you need hot water, the programmable timer activates the pump. This system is designed to work with zero flow, which explains why it uses less electricity. So when the sensor valve closes, the water is not being moved. When the sensor valve reopens, it is the pump that moves water from the hot water line to the cold water one.

Unlike other products, this one requires no electricity for the sensor valves to operate. They keep the water temperature at the faucet at 100 degrees, which is comfortably warm and safe.

What Does It Do?

Watts 500800 Instant Hot Water Recirculating SystemThe Watts recirculating system can provide enough hot water on demand for every faucet and shower at your home. Doing so, it reduces the wasting of water. Another benefit of this product is that it is a budget-friendly option if we take into account the fact that it saves up to 15,000 gallons of water annually. If we calculate this money-wise, we will come to the conclusion that you will spend only $ 0, 5 daily for its operation. Do the math, and you will see that this system will save you 10% of your bill annually.

If you want to use this unit without the sensor valve, you have to install a separate return line. However, you should be warned that you will have very hot water running since there is no temperature control at the faucet. In case your hot water line is in a loop, then the only thing you need to do is to hook the pump up to the sink furthest from the water heater, and you will have hot water in all faucets. If you have more than one plumbing loops at your home, then the Watts offers a system with additional sensor valves.
