Racold Vs AO Smith Geyser 25L: Which Geyser is better in 2024?

When it comes to providing hot water for your home, choosing the right geyser or water heater is essential. The two most popular geyser brands in India are Racold and AO Smith. But which offers better features, efficiency and value for money?

This detailed comparison of Racold and AO Smith geysers I will help you find which is better suited for your needs based on storage capacity, energy rating, heating efficiency, price and more.

Overview of Racold and AO Smith Geysers

Racold is one of India’s leading geyser companies with over 60 years of experience. Their most popular models like the Racold Omnis and Racold Eterno come in storage capacities ranging from 10 litres to 35 litres.

AO Smith is relatively newer in the Indian market but is a global leader in water heating solutions. Their AO Smith SDS-Green line offers storage tank capacities from 15-25 litres along with good heating efficiency.

Both companies offer multiple instant geyser to smart feature variants with different storage capacities, energy ratings, safety features and warranties. Let’s compare them across key metrics:

Comparison Criteria

  • Storage Options
  • Energy Efficiency
  • Heating Performance
  • Durability
  • Pricing
  • After Sales Service

Storage Capacity Options

In terms of storage sizes available, Racold offers more choice ranging from 1 Litre instant to 50 Litre large storage geysers. Popular options are:

  • 10L, 15L, 25L (medium family sizes)
  • 35L+ for larger households

AO Smith offers models from 3 Litres upto 50 Litres capacity including:

  • 15L and 25L for 2-4 family members
  • 35L and above for larger households

For a regular household, 25 L(25 litre vertical water heater) is typically adequate. Higher capacity leads to longer wait times for reheating so 25L to 35L gives the optimal hot water supply.

Energy Efficiency – 4 or 5 star storage water heater

Both Racold and AO Smith offer 5 star rated water heaters across various models based on the BEE star rating system.

Some examples of 4 and 5 star storage water heaters from both brands are:

  • Racold Omnis Lux Plus: 25 litres, 4 star rating
  • AO Smith HSE-SDS-Green: 25 litres, 5 star rating

Higher star rating indicates better energy efficiency leading to 20%+ savings on your electricity bills annually. So 5 star models make sense despite higher upfront costs.

Heating Efficiency

When it comes to hot water and maintaining temperature, AO Smith heaters use advanced PUF technology which helps retain heat better and gives around 20% faster reheating.

Racold also offers good heating consistency thanks to features like:

  • Titanium enamel glass lined tank to retain heat
  • Turbo electronically controlled heating element

So both heat water quickly, but AO Smith water heaters seem to have an edge in terms of efficiency.

Build Quality and Lifespan

Being premium models from leading brands, both Racold and AO Smith geysers are made of durable copper or stainless steel inner tanks with quality certified components.

Some signs of good build quality are:

  • Materials Used: Titanium/steel heating elements, durable tanks
  • Safety certifications like ISI and CE
  • Long warranties up to 7 years

They are reliable with good lifespans of 8+ years for general use. So not much difference between Racold and AO Smith here.

Pricing and Budgets

When I look at online prices, AO Smith heaters tend to be around 20-25% more expensive on average. For instance, for 25 L 5 star models:

Rs. 11,877 Rs. 14,000

Last update was on: April 9, 2024 12:51 am

So are AO Smith water heaters worth the extra cost? The higher initial price usually pays off within 2-3 years going by electricity savings so can be a good value.

After Sales Service

Racold has been in India longer (over 60 years) compared to AO Smith so has more extensive service network across the country.

But AO Smith is also ramping up by partnering with regional technicians. Customer reviews indicate mixed experiences for both brands when it comes to after sales service and repairs.

So weigh service center availability near you before deciding on either brand.

Frequently Asked Questions

Q. Which type of geyser is best?

For most homes, 25 litre 5 star storage geysers offer the optimal balance across performance metrics. Popular models like Racold eterno pro 25L or AO Smith 25L SDS Green are ideal.

Q. What geyser wattage is best?

2000 Watts to 4000 Watts is the optimal heating capacity range for regular usage across 2-4 people. Higher wattage above 4500W tends to increase electricity costs.

Q. Is a instant water heater good?

Instant geysers heat water quickly but tend to have limited flow and capacity. They work where need is intermittent. For regular supply to bathrooms, storage geysers are better.

Q. Horizontal or vertical geyser – which is better?

Vertical geysers take less space and fit well in small corners or balconies. Horizontal geysers allow easier maintenance but need more space allocation. So choose as per your layout.

AO Smith can be considered one of the best geyser brands in India due to its proven product quality and reliability over the last 20 years. The brand scores highly when it comes to durability, energy efficiency, safety features, and after-sales service across the country.
