What Is Bar Pressure in Geyser – Everything You Need to Know

In general, water heaters or geysers on the market are offered at various bar pressures depending on whether they are used in the home or for commercial purposes.

So, what does a water heater’s bar pressure mean? Because the water pressure in a water heater is measured in ‘bars,’ bar pressure is simply the water pressure that reaches your geyser/water heater’s water tank. In most circumstances, an 8 bar pressure geyser is recommended to be on the safe side regardless of the building’s rise.

Take a look at our round-up of the best home geysers on the market in 2021.

The rated pressure in the geysers varies from one building to the next, or from one apartment to the next.

For example, if you live on the third floor of a three-story structure, you will have less water pressure than someone who lives on the ground floor. This water pressure is also liable to alter over time.

During morning rush hour, every house in the building pulls water from the storage tank, resulting in low water pressure in the morning, but high pressure later in the day or late at night.

Keeping this in mind, we must choose the best water heaters for our residence.

Why is it critical to select the proper bar pressure?

You may be wondering why you need to buy a geyser with a high or low pressure rating after reading all of the above.

What happens if I don’t purchase a geyser with the correct bar pressure?

So, if you’re planning to buy a random geyser without doing any study, proceed with caution.

Let me explain if you reside in an area with extremely high water pressure and have purchased a geyser with a low bar pressure rating.

Your geyser’s inner tank will be harmed by the excessive water pressure. The inner tank’s delicate material would be unable to resist the enormous water pressure and would clash.

It can cause issues such as water leaking, increased heating time, short circuiting of geyser components, and electric shock.

To avoid these issues, you should purchase a geyser with the appropriate pressure rating.

In usually, the cold-water inlet is directly connected to the water heaters, which are directly connected to the building’s overhead storage tank outlet.

In this instance, the water pressure comes into direct contact with the inner walls of the water heater tank, causing the inner walls to thin and get damaged over time. And the geysers’ tank begins to leak water. Choosing between 6 and 8 bar pressure is entirely up to you.

To avoid this, it’s usually a good idea to invest in a home with an 8 bar pressure water heater.

How can you figure out the bar pressure in a water heater?
You can hire a plumber to compute the bar pressure in your home; he measures it using a pressure gauge device, which is straightforward. If you want to do it yourself, you’ll need a pressure gauge, which you can get here.

You can also manually calculate bar pressure. Consider the following calculations for a preliminary estimate.

calculating water heater bar pressure
In general, the bar pressure is the distance in metres from the bottom of the overhead tank to the bathroom tap or shower.

The bar pressure is 0.1bar if the distance from the bottom of the tank and the shower is 1 metre. To achieve 1 bar pressure, the distance between the above tank and the shower or tank must be 10 metres.

For more details, look at below table

For geysers, what is the optimal bar pressure?

The bar pressure is influenced by a number of factors. The building’s height, however, is the most important factor.

If you live in a high-rise building or a multi-story apartment, this is especially true. The water pressure would therefore be significantly higher.

In this instance, a geyser with a high pressure rating is required. To be on the safe side, geysers with an 8 bar pressure rating are recommended.

However, if you reside in a single-story or two-story home. Then there would be no need to be concerned about water pressure. In this instance, a geyser with a low bar pressure rating can be purchased.

Other factors that influence water pressure include:

The floor on which you reside
The number of taps utilised at the same moment depends on the time of day.


In the geyser, I’ve addressed everything about bar pressure.

I hope this answers all of your questions and allows you to calculate the bar pressure required for your geyser.

To be safe, choose water heaters that have a pressure rating of 6 bars or above. They are more sturdy and long-lasting and can readily sustain high water pressure.
