Install a Heat Pump to Meet Your Daily Hot Water Needs

Are you tired of high electricity bills from your water heater? Looking for a more efficient way to get hot water? Look no further than a heat pump water heater. This device can help you meet your daily hot water needs consuming 75% less electricity than a geyser.

Let’s understand in detail why heat pumps are the best choice for all Indian Households.

What is a Heat Pump Water Heater?

A heat pump system 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. 

Understand the Heat Pump Working Principle

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.

How is Heat Pump the Best Water Heater in India?

In Indian households, three main types of water heaters are common:

1. Geysers
2. Solar Water Heaters
3. Heat Pumps 

Let’s compare them!

Geysers

Geysers are most common in Indian households, because of their lower installation cost. It seems to be the cheaper option. But they consume huge amount of electricity, to meet your daily hot water needs. This results in high electricity bill every month. So in the long run, it is very costly.

Geysers heat water by directly using electricity to heat water. The process is very simple, but consumes huge amount of electricity in the process. So it is not energy-efficient. It increases your costs and has a negative impact on the environment. They directly convert electricity into heat. This is simple but inefficient.

Solar Water Heaters

Solar Water Heaters don’t use electricity at all. It uses sunlight to heat water. It is a great way to save electricity. But these systems have a few drawbacks:

• Time-consuming: Solar Water Heaters take 6 long hours to heat water. They need the entire day time to heat water.
• Dependent on Sunlight: Solar Water Heaters become inefficient during cloudy days or during lack of sunlight. You will not get hot water when there is no sunlight.
• Fixed Capacity: As this system takes a long time to heat water, it can provide you with a fixed amount of hot water only per day.

To avoid these drawbacks, heat pumps come into play.

Heat Pumps

Heat pumps consumes electricity, but is significantly lower than other electric water heaters like a geyser. It absorbs heat from surrounding air to heat water. So it is not dependent on sunlight, nor is it running fully on electricity. So a heat pump is efficient even on cloudy days. Today’s heat pump technology can absorb heat from the air even in extreme cold climates.

A heat pump is also regenerative. It means that it keeps absorbing heat from outside, and keep heating water. So the capacity is not fixed. The process is not time consuming, and can work during night time as well. It takes around 3 hours to heat water normally. 

As a heat pump uses electricity to extract heat and compress the heat, it is not 100% renewable. It is said to be up to 90% renewable. 

There is also another type of water heater, which is a hybrid water heater. It is a combination of a solar water heater and a heat pump. To know more about this system in detail, watch the video given below:

From the comparison, it is clear that a heat pump is definitely the best choice for Indian households. It is energy-efficient. It is an unpopular choice or Indian households because of its high upfront cost. But in the long-run it is the best alternative to save cost, while meeting your daily hot water needs efficiently. 

What are the Benefits of Heat Pumps?

Heat pumps come with a range of benefits:

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.

Conclusion

Installing a heat pump water heater is a smart move for any Indian household. It provides reliable hot water while saving energy and money. It is now time for us to invest in heat pumps to not only save cost, but also a way towards a sustainable future.
