Some recirculation pumps can serve as a separate, add-on component that uses a dedicated pipe loop for hot-water recirculation.

But once the outlet was shut off, the remaining warm water in the pipes did not return to the water heater for reheating. Instead, it stayed in the pipes and eventually turned cold. When the outlet was next turned on, this resting cold water exited the pipes first, ahead of the incoming hot water from the water heater.

Some hot-water recirculation pumps are built into the water heater itself. An integrated recirculation pump is ideal if your home lacks a dedicated return line, and you want to avoid the cost of adding one.

Another option is to purchase a “crossover kit” that is sold with the water heater and acts as a substitute for a return line.

A hot-water recirculation system delivers hot water to a faucet, shower or appliance in seconds, eliminating the usual water-wasting wait. The system does so by recirculating the water that remained in the pipes and eventually turned cold, back to the water heater, through either the cold-water line or a dedicated return line.

So why does the water coming from your “hot”-water faucet or shower run cold at first before finally turning hot? When that outlet was last turned on, hot water flowed through the pipes, right?

The most efficient “traditional” recirculation method would use a combination of both a temperature sensor and a timer to activate the system.

Instead of wasting energy by having hot water flow through the system continuously, some water heaters have an integral display on the front of the unit that allows homeowners to program the recirculation system to operate at specified times.

So what’s the solution? Is it possible to get truly “instantaneous” hot water? Yes, with a hot-water recirculation system that delivers hot water with virtually no wait time.

One type of recirculation system — and the focus of this blog — is a closed-loop, pump-assisted, hot-water recirculation system.

O'Keefe continued, "We are pleased with the acquisition of Dormont. Dormont is a well-managed company with a strong brand name. Dormont provides us access to several new channels of distribution while allowing us to offer a broader product line to our existing professional contractor customer base. Dormont's annual revenue for 2005 is expected to be approximately $56.5 million. Under the terms of the purchase agreement, Watts will pay $94.5 million in cash to purchase all of the outstanding stock of Dormont and the land on which Dormont's manufacturing facility is located, subject to a post-closing working capital adjustment. Watts intends to fund the transaction with borrowings under its credit facility and cash on hand."

Not only is this inconvenient (and downright uncomfortable if you’re standing in the shower), but a typical American home annually wastes thousands of gallons of perfectly usable potable water down the drain, thanks to lengthy wait times at hot-water outlets in the bath and kitchen.

The best way to prevent backflow is for potentially 'at-risk' properties to install and maintain a suitable device.

Whether you choose to install an external recirculation pump or go with a fully integrated system, the benefits for both are clear. A hot-water recirculation pump eliminates the need to wait for hot water by recirculating the water through your plumbing system, keeping hot water flowing and ready for the moment someone turns on the faucet or shower.

A recirculation pump can operate 24/7. But the energy savings would be nonexistent if the external circulator were always on and continuously recirculating hot water.

Hot-water recirculation dramatically reduces water waste. With time and temperature sensors, hot-water recirculation pumps can control when the recirculation kicks on, ensuring that energy is not constantly being wasted.

Watts Water Technologies, Inc. announced the signing of a definitive agreement to acquire Dormont Manufacturing Co., located in Export, Pa., in a stock purchase transaction.

It’s safe to say we’ve all experienced the inconvenience of having to wait for hot water to arrive at the faucet or shower — most of us every morning. You’ve probably grown accustomed to waiting several seconds or even a minute or two, depending on the distance to your bathroom or kitchen from your water heater in your basement, garage or utility closet on the opposite side of the house. The longer that distance, the longer the wait, the bigger the annoyance.

Watts Water Technologies' CEO, Patrick S. O'Keefe, said, "Dormont Manufacturing Co. is a leading provider of flexible stainless steel connectors for natural and liquid propane gas connectors. Dormont is a leader in commercial food service applications with a significant portion of North American sales and a leading position in the United Kingdom. Dormont also works with appliance OEM's to provide internal component assemblies and private label gas connectors, which are sold under the OEM brand with the appliance in multiple leading retails chains. Dormont also supplies residential gas connectors through multiple trade channels and home improvement retailers."
