Would You Prefer Instant Hot Water At Faucets & Shower?

How long do you have to wait for the water to heat up before you take a shower?

One minute? Three? Five?

You can only imagine how much water you’re wasting in that time.

If you have others in your house who shower daily, the amount multiplies.

Wasted water is money out of your pocket.

Eliminating the wait time for hot water will not only save you time and frustration, but it will also save you money.

A hot water recirculation system could be the solution. These systems recirculate water that cooled in the pipes back into the water heater. 

For a full recirculating pump system, an additional pipe is installed to your home’s plumbing to create a loop from the faucet to the water heater and back again.

At the end of your shower, the leftover hot water in the pipes is drawn back by the pump.

This way, water is never left in the pipes to cool off.

When you turn on your shower or bath water, hot water is already waiting for it. 

These systems also take energy costs into account.

Many of them come with sensors and timers.

The sensor will turn off the pump once the hot water has made a complete loop.

The timers will allow you to control when the pump activates.

You can set it to stay off during times you know you won’t need it, such as when you’re sleeping, at work, or away for the weekend.

Not all pumps come with these features, but they can be added later.

Another option for those who cannot install a new pipe is a system often referred to as a “comfort system.”

This system uses a cold water pipe to send water back to the heater.

Since this pipe already exists in your plumbing, there’s no need to install a new one.

These systems do not eliminate wait time completely, but they significantly lessen the wait time for fixtures that are farthest away from your water heater.

With this system, the cold water may run lukewarm for a while before it cools off completely, which can be troublesome in the summertime.  

Some recirculation pumps have a dedicated return line to send unused water back to the heater.

The pump is mounted on a pipe connected to the water heater.

Hot water flows from the water heater and passes by your home’s hot-water outlets.

These systems have three lines:

  1. a cold water line
  2. a hot water line
  3. a dedicated recirculation return line

That line starts at the fixture furthest from the water heater, which will vary depending on the layout of your home.

When the hot water outlet is closed, the pump circulates the water to return it to the water heater.

If the heater senses that the returning water is cold, it reheats it back to its set temperature.

This results in a continuous stream of hot water whenever you need it. 

Depending on what kind of recirculation system you are interested in, this upgrade can be a relatively low-cost project resulting in savings that pays for itself.

If everyone in your home wastes the same amount of water every single day waiting for it to warm up, you could lose hundreds or even thousands of gallons of water by the end of the year.

Your money is falling down the drain right along with it.

By eliminating that wait time, you’ll save money that you never realized you were losing.
