  • Instant Geyser
  • Geyser with a Storage Tank

Instant Geyser occupies less wall-mounting space when compared with the Geyser that comes with a storage tank.

Factors defining consumption of electricity

The wattage mentioned on the water heater is just an indication of the quantity of electric power that the geyser might consume. Let us look at the main defining factors.


The volume of hot water you use is the principal driving factor of electricity consumption. The electricity consumption is directly proportional to the volume of water you use.

Input water temperature

Colder water will take a longer time to reach the thermostat temperature. Hence, a water heater will consume more electricity in Delhi as compared to Chennai. This is because of the marked difference in the temperature of input water.

Thermostat temperature

Usually, all geysers have a standard 60C as the thermostat temperature. You have water heaters that have external controls to change this setting.

Standing loss

There is a misconception that water heaters do not lose heat. In fact, they do. This is known as standing loss, the heat lost through the water surface. BEE has a different definition of standing loss.

According to BEE, standing loss is the energy consumed by a water-filled geyser connected to an electric supply without anyone drawing the water. A lot depends on the quality of materials used in the manufacture of the water heater.

Hot water requirement

The guidelines are very simple to follow. (Source –

  • Normal bathing using buckets – 15 litres / person
  • Shower bath – 25 litres / person
  • Bath tub – 35 litres / person
  • Washing clothes – 10 litres / person
  • Washing utensils – 5 litres / meal

The quantity of water depends on the number of people in the house using the geyser.

Benefits of Bajaj Geysers

Bathing temperature

This temperature is different from the thermostat value. The ideal bathing temperature is in the range of 35C to 37C. The thermostat temperature is around 60C. This entails that you need to add cold water to the geyser water before taking a bath.

Calculation of Electrical units consumed by water heater

This is what you have been eagerly waiting for. You follow this simple formula from your physics text book.

Units consumed = Volume of water X Temperature difference X 0.0012

Hence, if your family uses 100 litres of water at 40C with input water temperature being 20C, you will use 100 X 20 X 0.012 = 2.4 units per day.

Is this a universal calculation?

The answer is NO. We have taken an ideal solution.

The other factors that determine power consumption are standing loss, the geyser size, and the way you use it. What does this imply?

Bigger heaters have a higher standing loss because of the larger surface area. As a thumb rule, a 100 litres geyser will have a standing loss of more than 1unit per day whereas a 70 litres geyser will have a figure of around 0.9 units / day.

One way to overcome this problem is to switch on the geyser just before using it and switching it off immediately after you finish your bath. You save electricity in this manner.

Effect of wattage on water heaters:

Wattage of the geyser has a direct relation with the time taken for heating the water. A 4.5 KW heater will heat the water faster than a 2 KW heater. It can reduce wastage of hot water. However, it does increase the overall load of the house thereby increasing the fixed charge component of the electricity bill.

Some Points To Note

1. If you are living in a place with a colder climate, the water heater will have to work more and extra power will be utilized. A water Heater in Cold North Indian state will consume more electricity than a Geyser in Andhra Pradesh.

2. The More Amount of Hot water you use, the more will be your electricity bill. The Thermostat temperature of most of the Geysers or Water Heaters will be around 60 Degrees Celsius.

Water Heaters will lose some heat, and this is called as standing loss. Always, opt for a Branded water purifier that has high-quality components.

3. Water Heaters wastes electricity when unused hot water is left in the storage tank. Always switch on the water heater before use and switch it off immediately after.

4. Most of the Geysers have a thermostat setting of 60 degrees Celsius which means the water can be heated up to 60 degrees Celsius.

5. Please note that the water having such high temperature is extremely dangerous to human skin and can cause severe first-degree burns. So, Make sure you mix the hot water with some cold water and lower down the temperature.

Geyser For Hard Water

If your water source contains more salts (Hard Water), you have to buy a Geyser that comes with a corrosion resistant tank. You can also install a water softener that converts the Hard water into the soft water, so there will be no damage to the heating element.

The ideal temperature for bathing is about two degrees more than the normal Human body temperature which is 37 degrees Celsius.

Best Water Heater – Frequently Asked Questions

1. Which is the better option, an instant egyser, or a storage geyser?

It depends on your requirements. An instant geyser can save power because it gives hot water instantly. The storage geyser is different because it takes more time in comparison. Hence, it consumes more power. While instant geyser can be more efficient, the storage geysers are less expensive. As far as maintenance is concerned, instant geysers require more maintenance, especially in areas having hard water.

2. What should be the ideal temperature setting for a geyser?

It is not possible to control the temperature in the case of instant heaters. In storage heaters, you can set the thermostat temperature level at more than 50 degrees Centigrade. Water below 50 degrees Centigrade can get contaminated by bacteria. In winter, the temperature setting should be between 60 and 65 degrees, whereas, in summer, it can be between 50 and 55.

3. Why should we switch off the geyser when not in use?

Many people believe that the thermostat maintains the temperature at the desired level. Its function is to regulate the electricity supply after heating the water to the set temperature. It switches off the supply, thereby saving electricity. However, the water cools down if left unused in the storage tank. If you fail to switch off the geyser, the thermostat will restart the electricity supply if the temperature dips below the set temperature. It can result in the consumption of unnecessary electricity.

4. Can water heaters give electric shocks while bathing?

One should ensure to have proper earthing in the house for all electrical equipment. Secondly, you should call a trained technician to install the water heaters. If they are not installed properly, the electric current does not get isolated from the water. It can flow through the water and cause electric shocks.

5. Is an instant geyser suitable for a shower bath?

No, the instant geyser is not at all suitable for a shower bath because it delivers hot water that your body cannot bear. The storage water heater is the ideal one to have a shower bath because you can switch off the geyser before the water reaches the set temperature.

6. What is the cut-off system in a geyser?

If you accidentally keep the geyser on in the absence of water supply, the geyser switches off as the coil temperatures reach a specific cut-off point. The heating element gets overheated, followed the tripping of the thermal switch that cuts off the electrical supply.
