Install Heat Pumps to make your Home an Energy Efficient Building

Do you want to reduce costs? Then replace your water heater with a heat pump. It will make your home an energy efficient building. It will not only save costs, but also save our planet.

In this blog, we will talk about the efficient energy use of a heat pump, and how it is the best choice for Indian homes. Let’s get started!

Energy Efficient Meaning

Energy efficiency is about using less energy to perform the same task. These appliances work smarter, not harder. They reduce waste and save you money in the long run. 

For example, heat pumps use 75% less electricity than an electric geyser to meet your daily hot water needs. Here, both the systems are doing the same work. But heat pumps are consuming significantly less amount to electricity. This is called being energy-efficient.

Wonder how does a heat pump achieve this? Let’s understand in detail about heat pumps, and how they work.

What is a Heat Pump?

A heat pump is a water heating device, to meet your daily hot water needs. It is energy-efficient, as it uses less electricity than other traditional water heaters. The difference lies in the working principle. Any traditional water heater, like a geyser, uses direct electricity to heat water. Whereas, a heat pump uses electricity to only transfer heat from one place to another. This heat is used to produce hot water, rather than electricity. 

How does a Heat Pump System Works?

A heat pump works on the principle of transferring heat from one place to another.

This system consists of two main components: an indoor unit and an outdoor unit.

The outdoor unit has two parts – an exhaust fan and a compressor. The indoor unit is the storage tank, where water is stored.

The exhaust fan absorbs heat from the surrounding air, while the compressor compresses the refrigerant gas, increasing its temperature. This heated refrigerant gas then passes through a spiral condenser inside the indoor unit, transferring its heat to the water stored in the tank. This process continues until the desired water temperature is reached.

Unlike traditional geysers that use a significant amount of electricity to generate heat, heat pumps consume less energy by simply moving heat from one place to another. This makes them more energy-efficient and cost-effective in the long run.

Understand Heat Pump Efficiency

How to understand whether a heat pump is really efficient or not? Let’s talk numbers. Heat pump efficiency is measured by the Coefficient of Performance (COP). What’s that? It’s the ratio of heat output to electricity input. A higher COP of heat pump means greater efficiency.

For example, a COP of 4 means for every unit of electricity used, you get 4 units of heat. That’s 400% efficiency! In India, a Coefficient Of Performance of heat pump above 3.5 is considered good. If you compare that to traditional heaters like a geyser, which rarely exceed 100% efficiency.

Are these systems only energy efficient? Heat Pumps are the best choice for Indian households, because it comes with several benefits. They are:

1. Cost-Effective

Heat pumps have high upfront cost. However, they make up for it through lower operating costs. Heat pumps transfer heat rather than generating it directly. This uses far less electricity – up to 75% less. Over its 10-15 year lifespan, a heat pump can save you hundreds or even thousands in energy costs. So it is actually a cheaper alternative to other traditional water heaters like geysers.

2. Long Lifespan

With proper maintenance, heat pumps last 15 years or more – significantly longer than standard electric geysers (8-10 years). So there is no need for replacement for a long time. This extended life cycle also contributes to it being a cost-effective option.

3. Reduced Water Wastage

Traditional water heaters constantly heat and reheat the same water, leading to significant energy losses. Heat pumps are automatic system as it heats water more efficiently. So when you run the hot water tap, the hot water flows instantly, and you don’t have to wait for it to flow. This results in a decrease in wastage of water. This conserves water, especially in households with long pipe runs.

4. Positive Environmental Impact

By consuming significantly less electricity than conventional water heaters, heat pump water heaters have a lower carbon footprint and contribute to reducing greenhouse gas emissions. This positive environmental impact is achieved by relying on renewable energy sources (ambient air) and minimizing the use of fossil fuels for power generation. Additionally, the longer lifespan of these systems further reduces the environmental impact associated with manufacturing and disposing of water heaters.

5. Efficient in Cold Climates

One common misconception about heat pump water heaters is that they may not perform well in colder climates. However, modern heat pump water heaters are designed to be efficient even in low temperatures. They can effectively extract heat from the surrounding air, even when the temperature drops below freezing. This makes heat pump water heaters a viable and energy-efficient option for hot water needs in various climates, including colder regions.

6. Manual Temperature Setting

Most heat pumps allow you to change temperature as per your requirements. This ensures you have hot water when needed without wasting energy by overheating the water beyond your requirements.

7. Availability in Different Sizes

Heat Pumps normally have an indoor and an outdoor unit. But many homes in India, specially in big cities, may not have that space available. For that, a single-unit heat hump is designed. It is also called Integrated Heat Pump.


Energy efficiency is a necessity, as it will help you save money on the long-run. So India must adopt appliances like heat pumps, which work efficiently, while consuming significantly less electricity. Install a Heat Pump to make your home an energy efficient building.

Before you buy a heat pump, make sure to check its coefficient of performance. Also, take help of a professional before you buy it. Make sure to choose the best heat pump for your home to achieve 100% efficiency. Remember, it is a huge investment, and it will only be worth if you make it right.
