Waiting for hot water is a pain. And it seems that no matter what kind of water heater you have installed—even if it’s an “on-demand” tankless system—you’ll still have to wait for hot water.

Like many homeowners, you may have simply accepted this as fact. But what you might not be considering is just how wasteful it can be to wait for the water to warm up.

Regardless of whether you’re waiting for the kitchen sink or for the shower to warm up, you can bet that you’ll be draining several gallons of cold water before you can start using the warm water. Multiply that cost every day, and for every person in the home who uses hot water, and you’ll see that this is no longer just an inconvenience.

Fortunately, there is a way for tankless water heaters in Glendale to offer truly instantaneous hot water, and it requires the help of a recirculating pump.

Why Don’t Tankless Water Heaters Provide Instant Heating Already?

You may be wondering why your tankless water heater doesn’t heat your water instantly in the first place. After all, isn’t that what these devices promise?

We understand where the message can get mixed up when discussing tankless water heaters. These heaters are often referred to as “on-demand systems,” which gives the impression that they provide hot water immediately.

What it actually means, however, is that the system will start heating the water immediately. There’s no need to heat a large batch of water before dispensing it, such as in the case of a storage tank heater. Tankless water heaters will only use energy when prompted, and they can provide hot water endlessly.

So, What Is a Recirculating Pump and How Does It Help?

Technically, a tankless water heater could heat water much faster than they do, but the sudden increase in temperature would damage the device. That’s why you first must let the water run before it can start safely raising the temperature. However, as mentioned above, this process wastes plenty of cold water.

A recirculating pump takes that cold water and pumps it back into the system. This allows you to avoid wasting water, and it even helps heat the water significantly faster.

However, your recirculating pump must fulfill a few characteristics:

  • It needs a high-speed pump to return cold water back into the water heater instead of sending it down the drain.
  • It shouldn’t operate continuously. Continuous operation puts a lot of stress on the water heater and will void or reduce your warranty.
  • It does not keep your water lines hot unless there’s a demand. Otherwise, it would waste energy and increase the chances of pinhole leaks developing.

In other words, you can’t just have any recirculation pump installed. These devices exist for both tank and tankless water heaters, but due to the unique construction of a tankless system, they require a specific type of recirculation pump. That’s where you’ll need a professional to help install the right system.
