instant geyser price in Lahore

What are Instant water heaters?

Instant water heaters: Best electric geysers in Lahore have a small storage capacity and a high heat output. They have a small storage capacity of 1 to 3 liters. DC heaters are also known as tank less water heaters. They are smaller, hotter and provide hot water immediately. These instantaneous water heaters can be installed in different locations in the home. If needed, they provide hot water continuously as compared to a traditional storage tank.

How do water heaters work?

A tankless water heater or instant water heater heats water on demand. Instead of using a storage tank to heat water, it heats the water directly. When the hot water tap is turned on, cold water flows through the pipes to the heater and an electric heating element heats the water. As a result, the DC heater provides a continuous supply of hot water. As with a buffer tank or conventional boiler, you don’t have to wait until you have enough hot water.

Typically, instantaneous water heaters provide hot water at a rate of 2 to 5 litres per minute.

How long does it take for a tank less water heater to heat water?

The time it takes a tank less or best electric geyser in Lahore depends entirely on the ambient temperature. In winter, the boiler temperature is usually between 4 and 21 degrees Celsius. Sometimes when the water temperature falls below 4 degrees Celsius, the water turns to ice. If all these temperature fluctuations are taken into account, you will know how long it takes the boiler to heat the water to a high temperature of about 60 degrees Celsius and an average temperature of about 39 to 40 degrees Celsius. The final calculation is as follows: It takes an average of 1 minute for a boiler to heat water to the average temperature and an average of 2 minutes to heat water to a high temperature.

 Benefits of a tank less or instant water heaters

There are many benefits to purchasing an instant or tank less water heater:

  • These heaters are compact, so they take up less space than traditional water heaters.
  • Instant geysers have no standby losses, i.e. the hot water remaining in the tank is cooled down when using, whereas there is no need to store hot water.
  • Less water is wasted because tank less water heaters provide hot water immediately on demand.
  • There is no need to wait for long periods of time for hot water in the bathroom. Thanks to instant water heaters that solves this problem.
  • Tank less water heaters also have the advantage of high energy efficiency, low electricity bills, and low fuel consumption compared to traditional geysers.

How to choose the right one for your homes?

Water geysres play an important role in our homes. However, choosing the right geyser can be the biggest hurdle.

Therefore, we are here to explain both types in detail. This will help you choose the right type for your needs.

Working process of the instant geysers

  • The working process of the instant geyser is advanced. And it gives you hot water just a few moments after you turn the geyser on.
  • Most of the instant geysers come with a capacity of holding 2–3 liters of water. They are best for instant usages like washbasins, kitchens, and bathrooms as well.
  • But if you have a 3 liter instant water heater, you may face some difficulty in taking shower. The reason is that the general water flow of the shower is 8 liter per minute.
  • And if you want a continuous water flow, you may not get the right temperature. Or you have to wait.
  • Water temperature is a vital factor in instant geysers. If the water temperature is 15C it will take two minutes to heat it to 60 degrees and one minute to 40 degrees.
  • But in the lower temperature, you may not get satisfactory results.
  • Water flow is another factor in this case. Most of the instant heater ignites only by sensing the minimum water flow of 0.5 gallons per minute.
  • However, some products have the capacity to work on a lower flow rate of 0.26 gallons per minute.

The above explanation is suitable for Pakistani instant water heaters. In foreign countries, the working process is a little different.

The working principle of the quick-heating geysers

  • Quick heat geysers work on a very advanced principle. After switching on the geysers, it will provide you with hot water in just a few minutes.
  • Most quick-heat geysers have a capacity of 2-3 litres of water. They are best suited for direct use in sinks, kitchens and bathrooms.
  • However, if you are using a 3 litre water heater, it may be difficult to take a shower. This is because the typical water flow rate for a shower is 8 litres per minute.
  • If you want a constant flow of water, you may not have the right temperature. Or you may have to wait.
  • Water temperature is an important factor in hot water geysers. At 15 degrees Celsius, it takes two minutes to heat water to 60 degrees and one minute to heat water to 40 degrees.
  • However, at lower temperatures you may not get satisfactory results. The problem with instantaneous boilers, therefore, is that they are only suitable for southern Pakistan where the water temperature is high.
  • The rate of water flow is another factor in this case. Most boilers will only work if they detect a minimum water flow of 0.5 gallons per minute.
  • However, some boilers have been able to operate at lower flow rates of 0.26 gallons per minute.
  • The above explanation applies to boilers in Pakistan. Abroad, the mode of operation is slightly different.

These boilers operate as follows.

  • When the switch is turned on, cold water flows into the boiler. The water flow sensor in the boiler detects the water flow and starts the burner and heat exchanger.
  • As the water circulates through the heat exchanger, it is heated and distributed through the hot water tap. A red and green indicator light shows whether the water is being heated or not.
  • When the green light is on, the hot water tap can be opened to release hot water.


Safety in use

The boiler has a thermostat which switches off the power when the water is hot enough. So you don’t have to worry about overheating. If you want to know more about thermostatic boilers, read the article ‘What is a thermostatic boiler’. In addition, the boiler does not store water, which reduces the risk of pressure and explosions.

Low energy consumption

Low energy consumption as there is no long waiting time and the amount of water stored is small.

Ideal for busy mornings

As most of us are in a hurry in the early morning, a quick supply of hot water is essential. With an instantaneous electric water heater, you can enjoy this convenience.


Boilers can run smoothly for 15-20 years. If you use natural gas, the lifespan can even be extended by several years.

Requires less space

With smaller tanks, these geysers are also more compact. These water geysers are ideal if you have less space in your home or want to install a water heater in a small bathroom.

Respect for the environment
  • They do not emit greenhouse gases. They are therefore not harmful to the environment.
  • The working principle of thermal storage geysers
  • The name of the geysers shows how it works. These thermal storage geysers have a storage tank that receives water and heats it up.
  • The water is then taken from a tap. The storage tank has insulated walls.
  • This blocks the heat.
  • The insulating walls determine how long the water stays hot after the switch is turned off.
Benefits Easy Installation

Tank less water heaters can present a number of risks during installation, while storage tanks do not.

With the purchase of a storage tank, you will not have to worry about installation.


Another key feature of this type of water heater is that it is very affordable. Therefore, if you have a higher budget, you can get a very good product.

Supplying water to multiple taps

Storage water heaters can supply hot water to kitchens, bathrooms and other toilets. As a result, they can give you more benefits at a lower cost.

Difference between instant and storage water heaters

  • If you already know the difference between the two, then you may have noticed that in the competition between instantaneous water heaters and storage water heaters, instantaneous water heaters are superior in terms of speed.
  • On the other hand, water boilers have a smaller water capacity.
  • However, these water heaters are durable, fit perfectly into your busy schedule, and consume less electricity.
