Heat Pump Water Heater: The Best Choice for Indian Homes

Imagine an eco-friendly water heating solution that cuts your electricity bills and requires minimal maintenance. Heat pump water heaters fit the bill perfectly – sustainable, energy-efficient, and hassle-free. It consumes far less electricity compared to traditional geysers. In this blog what a heat pump is explained and how does it work. 

What is a Heat Pump?

A Heat Pump Water Heater is an energy-efficient appliance that uses a refrigeration system to transfer heat from the surrounding air to heat water. It absorbs heat energy from the environment, which is then compressed, and then the water stored in the tank is heated. As electricity is required only in the compressor, it consumes only one-fourth of the electricity consumed by geyser. 

A Heat Pump normally heats water to 55 degrees but can be changed as per the requirements.

How does a heat pump work?

There are three Heat Pump components. They are:

  1. Exhaust Fan: The exhaust fan is responsible for drawing in air from the surrounding environment. It plays a crucial role in absorbing heat from the air, which is then utilized to heat the water in the tank.
  2. Compressor: The compressor is a vital component that compresses the refrigerant gas, increasing its temperature and pressure. This compression process allows the refrigerant to transfer heat more efficiently, enabling the system to heat the water effectively.
  3. Tank: The tank is where the water is stored and heated. It is designed to hold a specific volume of water and is equipped with coils or a heat exchanger to facilitate the transfer of heat from the refrigerant to the water.

The heat pump water heater utilizes a refrigerant to absorb heat from the surrounding air through the evaporator coils. The exhaust fan draws in air over these coils, causing the refrigerant to evaporate. The gaseous refrigerant is then compressed, increasing its temperature. This hot, high-pressure gas enters the condenser coils inside the water tank, releasing its heat to the water. After condensing back to a liquid, the refrigerant undergoes an expansion process before repeating the cycle. This continuous closed-loop system efficiently transfers environmental heat to the water without directly generating heat, resulting in energy savings and eco-friendly operation.

How is a heat pump water heater better than a traditional electric geyser?

A Heat Pump Consumes 75% Less Electricity

1. Automatic System:

Heat pump water heaters have an automatic backup electric coil. This coil activates when there is no heat available from the surroundings. It ensures a constant hot water supply up to 55°C. Need hotter water? No problem – the coil can further heat the water above 55°C. In contrast, the temperature of water heated using geyser cannot be changed as per the requirements.

2. Saves Electricity:

A significant advantage is electricity savings. Heat pump water heaters consume only one-fourth of the electricity units used by geysers. This translates to lower electricity bills and cost savings for homeowners. Geysers consume much more electricity, resulting in higher utility costs. This leads to heat pump efficiency.

3. Lesser Waiting Hours:

With heat pump water heaters, hot water is always available on demand. There is no need to wait for the water to heat up, as is often the case with geysers. This convenience eliminates the frustration of lengthy wait times.

4. Sustainable:

Heat pump water heaters are an eco-friendly and sustainable option. They harness heat from the surrounding air instead of generating heat directly. This process is more environmentally friendly and reduces the carbon footprint. Geysers, on the other hand, rely on direct heating methods that can be less efficient and more harmful to the environment.


Heat pump water heaters are the clear winner over traditional geysers. They provide automatic hot water, save substantially on electricity bills, and ensure hot water is always available. Most importantly, they are an eco-friendly and sustainable choice. This is due to heat pump efficiency. The initial cost may be higher, but the long-term benefits make heat pump water heaters a wise investment. Therefore, Heat Pump best choice for India!
