How To Get Hot Water Faster from A Tankless Water Heater

Everybody who has seen liquid go down a drain while hoping for it to heat has fantasized about quick hot water. It may not be as well-known as the search for meaning. Even so, almost everyone who has seen water go down a sewer while waiting for this to heat up has thought about it. It’s inconvenient to wait for hot water when you need it. When you understand how much water you’ll be wasting, you might feel a little terrible, but still not enough to have a cold bath first thing every morning. So, we think you want to know how to get hot water faster from a tankless water heater?

Continue reading the article to know the reasons and tips you will need to solve the problem and learn how to obtain them.

Why Don’t We Get Instant Hot Water from A Tankless Heater?

Before going to how to get hot water faster from a tankless water heater, the following are some issues addressing why we don’t get instant hot water from the heater:

  • Water left in pipes

Even with a tankless water heater, it’s one of the most typical reasons you’ll have to wait for hot water. When you switch everything on, water will start to flow from the faucet, but this will rarely be straight from the heater, and it takes the place of water inside the pipelines and reaches the tap.

  • Flow

The speed at which the water flows may also impact the waiting period. Fixtures typically have a modest flow velocity, and some include a volume restrictor meant to reduce the quantity of water from the institution.

Even though the devices save water and money, they cause a delay in the water supply. You wait even longer for hot water when it takes longer to come out.

  • Distance

Another factor to consider is how far the hot water must flow from the heater to a faucet, sink, or shower. The hot water will take a long time to reach the tap at the second-floor sink once the tankless unit gets placed in the basement.

The longer it takes to obtain hot water, the longer it would take.

  • Sediment buildup

The harshness of the water in the location might affect your water heater’s effectiveness. Even a conditioner won’t eradicate the problem because certain minerals will still exist. Minerals build up in the system even though the water does not stay in it for a long time.

When your tankless water heater has trouble heating the water, its longevity and performance suffer, and you don’t get as much hot water as you should.

  • Outside temperature

Even if the tankless water heater operates well, it will try to provide continuous hot water when the outside water temperature is shallow. Poor performance is all too common when living in a frigid place.

If the outside air is chilly, the subsurface water entering the pipes will also be cold. Therefore, the tankless heater would have to work much harder to raise the water temperature to the desired level. Even though the water is hot, the pipes may be cold, rendering the water heater ineffective and inefficient.

  • Malfunctioning

Even when a tankless heater gets designed to last long, its longevity may be compromised and begin to work poorly. Improper installation, hard water, and inadequate maintenance are just a few of the numerous issues that affect the unit’s functionality.

How To Get Hot Water Faster From A Tankless Water Heater?

There is no easy fix for increasing your tankless water heater’s efficiency. The fundamental restriction is the unit’s power. Unless you adjust the system, if the tankless heater only could heat the water at a set rate, you’ll be stuck with that rate. The following are two of the most prevalent ways to acquire hot water faster:

  • Recirculating pump

The hot water goes via the pipes to your chosen tap after passing through a water heater. As a result, when the faucet gets turned off, the pipeline water is left to cool.

You may have to wait for a new batch of hot water all the time you turn on the tap, depending on the distance between your water heater and the faucet. A recirculating pump can get used to overcome this problem.

The water in the pipes gets recirculated and then gets connected to the water heater by a recirculating pump. You’re building a “dedicated loop” between your water heater and other fixtures throughout your home.

A recirculating pump gets featured in many tankless heaters. However, a recirculating pump is incompatible with many tankless heaters. As a result, if this is crucial to you, choose one with this feature.

Our next solution could be more suitable if you want to save the cost of creating a loop.

  • Secondary Water Heater

You might buy a supplementary heater rather than a circulation loop for each valve or tap, and you need hot water immediately. A tiny water heater directly attached to a faucet, shower, or fixture is known as a point-of-use water heater.

This water heater heats any remaining cold water in the pipes. On the other hand, the central tankless heater warms water from below.

A second water heater is usually less potent than the primary heater, filling in the gaps. In contrast, the direct heater heats your water to the desired temperature.


To sum up, the above article covered one of the most prevalent areas of concern with these trendy water heater designs. A tankless heater is a terrific method to save money and space, but it has a few drawbacks compared to a standard heater. As you’ll see, with some innovation and clever plumbing, you can ensure that you always have access to hot water.
