What are the Different Water Heaters Available in India?
There are many water heaters available in India. Some of them are listed below:
- Geysers: These are electric water heaters that heat water using electricity.
- Tankless Water Heaters: Also known as instant water heaters, these devices heat water on demand without a storage tank.
- Gas-Powered Water Heaters: These use natural gas or LPG to heat water in a storage tank.
- Solar Water Heaters: These systems use solar energy to heat water stored in insulated tanks.
- Heat Pumps: These device use electricity to transfer heat from the surrounding air to water in the tank.
- Hybrid Water Heaters: Combining heat pump technology with solar water heater. These systems offer increased efficiency and backup heating capability.
Why is a Heat Pump the Cheapest?
A Heat pump water heater is the most energy-efficient option for heating water. This makes it the cheapest to operate in the long run.
A heat pump has 3 components:
- Exhaust Fan: An exhaust fan draws in air from the surrounding environment.
- Compressor: The compressor pressurizes the refrigerant, increasing its temperature.
- Storage Tank: The hot refrigerant passes through a condenser coil inside the insulated tank, transferring heat to the water.
This process consumes significantly less electricity than traditional electric water heaters, resulting in lower operating costs. Additionally, heat pump water heaters can extract heat from the air, effectively multiplying the energy input, making them incredibly efficient and cost-effective.
What are Some Other Benefits of Heat Pump Systems?
Aside from their cost-saving potential, heat pump water heaters offer several other advantages:
1. Long Lifespan
Heat pumps have a typical lifespan of 10-15 years, which is significantly longer than other water heaters. This is because they have fewer components exposed to intense heat, reducing wear and tear. The compressor and fan are the only moving parts, making them more durable and less prone to breakdowns.
2. Reduced Water Wastage
If a geyser is installed in your home, you must have noticed that it takes few minutes before hot water comes out of the tap. But it is not the case for heat pump systems. It will give you instant hot water, as you will switch on the hot water tap. This reduces wastage of water.
3. Positive Environmental Impact
By consuming up to 75% less energy than other electric water heaters, heat pumps have a much lower carbon footprint. They consume less electricity. This reduced energy consumption translates into lower greenhouse gas emissions, making them an eco-friendly choice.
4. Efficient in Cold Climates
Heat pump systems can extract heat from the air even when the temperature is as low as 5°C (41°F). This makes them suitable for most parts of India, including colder regions. They use advanced technologies like compressor blankets and intake air duct systems to maintain efficiency in low temperatures.
5. Not Dependent on Sunlight
Solar Water Heaters also save money, as they don’t use electricity at all. But the disadvantage is that it is highly dependent on sunlight. So at places where there is lack of sunlight, it will not work efficiently. But, a heat pump will work efficiently with just 3 hours of electricity.
Conclusion
If you are wondering – which is the cheapest water heater to run, it is a heat pump. This is the time for every Indian household to install a heat pump. It is cheaper in the long run. Not just that it is extremely efficient, uses less electricity. Also it has a positive impact on the environment.
