What is bar pressure or rated pressure in water heaters?

bar pressure in geysers

Generally, the water heaters or geysers in the market are sold on different bar pressures that are required for the home or commercial purpose.

So, what is bar pressure in a water heater? The water pressure in the water heater is measured by ‘bars’, therefore bar pressure is nothing but a water pressure that hits your water tank in a geyser/water heater.

This rated pressure in the geysers varies from building to building or flat to flat in an apartment.

For example, if you are living on a loft of three stored building hence you will receive less water pressure than a guy living on the ground floor. And, this water pressure is subject to change from time to time.

In the morning rush hours, every house in the building withdraws water from the storage tank hence the water pressure is low in the morning but the pressure is high during noon or later in the night.

So, keeping all this in mind we must buy the best water heaters for home.

Also, check our recommendations on best geysers based on bar pressure that arr suitable for all most all kinds of buildings.

The role of Bar Pressure in Geysers

In general, we directly connect the cold-water inlet to the water heaters which is directly connected to the outlet of the overhead storage tank of the building.

In this case, the water pressure directly gets contact with the inner walls of the water heater tank, over the period of time the water heater inner walls get thin and damaged. And, start to leak water from the geysers tank. Finding 6 bar pressure vs 8 bar pressure is completely uour choice.

Hence to avoid this, it’s always suggested to get an 8 bar pressure water heater for your home.

How to calculate bar pressure in water heaters?

To calculate the bar pressure in your house you may take the help of plumber he measures it through a pressure gauge instrument and it is simple. If you wish to do it yourself then buy a pressure gauge from here.

You can also calculate bar pressure manually. For the rough estimation let’s look at the following calculations.

calculating bar pressure in water heaterIn general, the bar pressure is a distance calculated in meters between the bottom of the overhead tank to the tap or shower in the bathroom.

Suppose, if the distance between the bottom of the tank to the shower is 1 meter then the bar pressure is 0.1bar. So, in order to achieve 1 bar pressure, there must be 10 meters gap between the overhead tank and the shower or tank.

For more details, look at below table

Distance Bar pressure
1 metre 0.1 bar = Low
2 metres 0.2 bar = Low
3 metres 0.3 bar = Low
4 metres 0.4 bar = Low
5 metres 0.5 bar = Low
6 metres 0.6 bar = Low
7 metres 0.7 bar = Low
8 metres 0.8 bar = Low
9 metres 0.9 bar = Low
10 metres + 1.0 bar = High

What is the bar pressure required for geysers?

Usually, the geysers are employed in households that can be distinguished in two types of high rise buildings or an independent house (G+1).

For high-rise buildings or apartments, there will be a lot of distance between the overhead tank and the lowest floor. So naturally, the water pressure is high hence the bar pressure required is high.

It is always recommended 8 bar pressure geysers for high rise buildings for better results in water pressure handling.

In case of an independent house, the pressure is slightly low, therefore it is recommended to get a 6 or 6.5 bar pressure water heater for your home.

In some occasions, the pressure might not work equally in your water taps and showers, the reason is simple you need to buy water taps which are suitable for low to high pressures basing on your water pressure.

safety valves

Along with high bar pressure, these days every water heater in the markets gets a safety water pressure valve, the main function of the pressure valve is to discharge the water from the water heater during water flow more than the threshold. This water pressure saves the water heater from major failure.

Conclusion

At the end of the day, the life and efficiency of the geysers matter the most no matter. So, choose the best-rated pressure water heater depending upon the water flow travel distance in your house.
