How long is a geyser's tank actually covered under warranty in India?

It depends on the brand and, for some, the specific model. Havells' published terms give 7 years on the inner container across its storage range. Racold's published terms state 7 years on the storage tank generally. Bajaj's flagship Shield and Armor series storage models carry 10-year tank warranties, though its budget and instant-heater lines get less. AO Smith's Elegance Prime series states 7 years on the tank - but unlike the other three, AO Smith's terms make that figure conditional on registering the product, not automatic from the invoice date alone. Crompton's official 2025-26 product catalogue lists up to 10 years on its flagship Solarium Care storage line, with most of its other storage models at 7-8 years.

Does my geyser's tank warranty apply automatically, or do I need to register it?

That's the one real difference between these brands. Havells', Racold's, and Bajaj's published multi-year tank figures apply from the date of purchase shown on your invoice, with no separate registration step described in their terms. AO Smith is the exception: its published terms state that extended warranty on the heating element or tank requires registering at its call center or online within 60 days of purchase - unless installation was done through an AO Smith-authorized service provider, in which case it's applied automatically. If you own an AO Smith unit and skipped registration, it's worth checking whether the 60-day window has already closed. Crompton does run its own product-registration scheme, but it's worth being precise about what it actually covers: Crompton's published terms for that scheme state it applies only to its fan categories, not water heaters - so don't assume it extends your geyser's coverage the way it would a Crompton fan's.

What is an MFV and why does it matter for my geyser's warranty?

MFV stands for multi-function valve (sometimes called a multi-function safety valve) - a single fitting on the cold-water inlet that does four jobs: releases excess pressure, stops water flowing backward into the mains, vents expansion during heating, and lets you drain the tank. A storage geyser is a sealed, pressurized tank that heats water to a set temperature continuously, and the MFV is the part that keeps that pressure from building past a safe limit. Havells' published warranty terms state plainly that the warranty is void if the MFV isn't installed - not because it's a minor accessory, but because it's the safety device the rest of the warranty assumes is doing its job.

Will hard water void my geyser warranty even if I never touched the unit?

Possibly, and this is worth knowing before you buy in a hard-water area. Racold's published terms list 'water quality issues, including scale or sediment deposition' as a condition that voids coverage. Bajaj's general appliance warranty terms separately exclude 'failure of parts due to scale deposition' from coverage entirely. Neither brand is blaming you for the water in your area - but neither is covering the heating-element or tank damage that hard water causes over time, either. If you're in a known hard-water area, ask about periodic flushing and anode-rod replacement (where the unit has one) as preventive steps, since the warranty terms themselves won't compensate for skipping it.

Does a geyser need periodic servicing to keep the warranty valid, like an air conditioner does?

Not in the same explicit, dated-interval way an AC does - none of the five brands' published terms state a fixed 'service every N months' requirement the way LG's or Voltas's AC terms do. But it isn't a clean 'no' either: Havells' warranty terms state coverage 'only applies if... maintenance has been carried out as instructed,' and its own instruction manual recommends getting the unit serviced once a year by an authorized technician. So while there's no numeric interval printed on the warranty card itself, skipping service entirely still weakens your position if a claim is ever disputed - it's a softer requirement than an AC's, not an absent one.

How Long Is Your Geyser's Tank Actually Covered? What Racold, AO Smith, Bajaj, and Havells Warranty Terms Really Say

By Applimate Team · August 21, 2026 · 11 min read

Key takeaways

The inner tank warranty is the number that matters, not the 1-2 year base warranty - Havells covers it for 7 years, Bajaj and Crompton's respective flagship models up to 10 years, Racold up to 7 years, and AO Smith's Elegance Prime series 7 years, all published from the date of purchase.
AO Smith's tank and heating-element coverage isn't automatic the way most of the other brands' published terms are - it only applies if you register within 60 days of purchase, or if an AO Smith-authorized technician handled the installation.
Bajaj's general warranty terms explicitly exclude 'heating tubes/rods for failure or breakage' and damage from 'scale deposition' - two of the most common real-world reasons a tank or element actually fails in hard-water areas.
Nearly every brand voids the warranty if the multi-function safety valve (MFV) isn't installed - the one condition genuinely specific to geysers, and it exists because that valve is what keeps a sealed, pressurized tank from becoming dangerous, not just a paperwork formality.
Crompton's official 2025-26 product catalogue lists tank warranties up to 10 years on its flagship Solarium Care line and a multi-function safety valve as standard equipment - but unlike Havells, Racold, Bajaj, and AO Smith, Crompton doesn't publish a dedicated warranty terms page spelling out what voids that coverage, so its own warranty card is the only place to check the specifics.
Bajaj's general appliance warranty terms require any defect to be reported within just 3 days of the invoice date to remain eligible for a refund - a far tighter window than anything in the warranty terms of the other appliance categories we've covered.

Buy a geyser and the box usually shouts one number at you - “10-year warranty” or “7-year tank warranty” - in large type near the brand logo. What it doesn’t say on the box is whether that number applies the moment you plug it in, or only if you complete a registration step within a deadline you’d have no reason to know about. Havells’ published terms cover the inner tank for 7 years starting from your invoice date, no extra step required. AO Smith’s comparable 7-year figure on its Elegance Prime series works the same way only if you register within 60 days of purchase - or skip that step entirely because an AO Smith-authorized technician did the install. Bajaj’s flagship storage models advertise up to 10 years on the tank, but its general warranty terms separately exclude the single most common reason a tank actually fails in Indian conditions: scale buildup from hard water. Crompton’s flagship Solarium Care line matches that 10-year figure - but Crompton’s own official materials don’t publish the kind of dedicated void-conditions page the other four brands do, which is itself worth knowing before you assume the fine print reads the same way. Five major brands, five warranty cards, and the number on the box turns out to be the beginning of the question, not the answer.

Why the tank warranty is the number that actually matters

Every geyser sold in India carries a base product warranty, typically 1 to 2 years, covering the unit as a whole against manufacturing defects. But the inner tank - the sealed steel container that holds and heats the water - is the part that’s genuinely expensive and disruptive to replace, and every brand we checked backs it with a separate, much longer warranty on top of the base coverage. This is the same pattern this site has already documented for refrigerator compressors: manufacturers know which single component is the one that actually determines whether an appliance is worth keeping, and they compete on that component’s coverage specifically rather than on the whole-unit number most buyers remember.

For a geyser, the tank is that component. A geyser with a leaking tank isn’t a geyser with a minor fault - it’s a wall-mounted unit slowly leaking water into your bathroom, and replacing the tank generally means replacing the unit. That’s exactly the failure a multi-year tank warranty exists to protect against, which is why the number worth writing down isn’t the “2-year warranty” sticker on the box, but the tank-specific figure buried in the terms.

What each brand’s published terms actually say

Based on the currently published terms of Havells, Racold, Bajaj, AO Smith’s, and Crompton’s India operations:

Brand	Tank warranty	Heating element / other	Registration required?
Havells	7 years (Inner Container)	4 years element, 2 years comprehensive on other electrical components, 1 year on shock-safe plug	Not stated - applies from invoice date
Racold	Up to 7 years (storage tank)	3-7 years on heating elements, 2-year comprehensive on the product	Not stated - applies from invoice date
Bajaj	Up to 10 years (Shield/Armor series storage models)	Up to 6-year element, 4-year product on flagship models; shorter on budget/instant models	Not stated on flagship models - applies from invoice date
AO Smith	7 years (Elegance Prime series)	Varies by model	Yes - register within 60 days, or auto-applied via authorized installation
Crompton	Up to 10 years (Solarium Care, flagship storage line); 7-8 years across most other storage models	2-6 years element and 2-year product depending on model	Not independently published for water heaters - Crompton’s own 15-day registration scheme is stated to apply to its fan categories only

A few things worth noticing beyond the headline numbers:

AO Smith’s coverage isn’t automatic the way most of the other brands’ is. Its published terms state that “customer can avail Extended Warranty for heating element or tank of Water heater by doing a warranty registration process at call center… within 60 days from the date of purchase,” and that this step is skipped only “if customer did their product installation through authorized service provider of A.O. Smith.” If you bought an AO Smith unit, had it installed by a local plumber rather than an AO Smith technician, and never called the registration number, the multi-year tank figure on the box may not actually be active on your unit.
Bajaj’s headline “10-year tank warranty” comes with a carve-out that matters more than the number itself. Its general Appliances warranty terms - which govern its water heaters alongside its other appliance categories - explicitly list “heating tubes/rods for failure or breakage” and “failure of parts due to scale deposition” among the things the warranty does not cover. In a country where hard water is common in large parts of the north and west, scale deposition is not a rare edge case - it’s one of the ordinary ways a heating element actually degrades over years of use.
Bajaj’s terms also give you just 3 days from the invoice date to raise any defect if you want to remain eligible for a refund rather than a repair - a noticeably tighter window than anything in the warranty terms for the appliance categories this site has covered so far.
Racold is the only one of the five whose own website copy gives a range rather than a fixed figure for the heating element - “3-7 years,” depending on the model - which means the tank number and the element number can diverge more on a Racold unit than the marketing headline suggests.
Crompton’s flagship figure matches Bajaj’s, but the fine print doesn’t. Crompton’s official 2025-26 product catalogue confirms the tank/element/product warranty years model by model, and lists a multi-function safety valve as standard equipment across the storage range - but unlike Havells, Racold, Bajaj, and AO Smith, Crompton doesn’t publish a dedicated warranty terms-and-conditions page spelling out what voids that coverage. That’s not evidence its terms are worse, just less publicly documented - the physical warranty card that ships with the unit is the more reliable source for a Crompton geyser specifically.

The one condition that’s genuinely specific to geysers: the safety valve

Every other warranty guide on this site has covered conditions that also apply to fridges, ACs, or appliances generally - unauthorized repair, non-genuine parts, voltage damage. Geysers have all of those too, but they also have one condition that doesn’t show up anywhere else: the multi-function valve, usually shortened to MFV, fitted to the cold-water inlet.

The MFV isn’t an accessory - it does four jobs on one fitting: it releases pressure if it builds past a safe limit, it stops water flowing backward into the mains supply, it vents the water’s natural expansion as it heats, and it lets you drain the tank when needed. A storage geyser is a sealed tank holding pressurized, heated water around the clock, and the MFV is the single part standing between normal operation and a pressure buildup with nowhere to go. That’s why Havells’ published warranty terms state outright: “Warranty Void if MFV is not Installed with water heater.” It isn’t there to catch you out on a technicality - it’s the one component the warranty treats as non-negotiable because the alternative is a genuine safety risk, not just an inconvenience.

"The MFV isn't there to catch you out on a technicality - it's the one component the warranty treats as non-negotiable because the alternative is a genuine safety risk."

If you’ve ever had a geyser installed and the technician didn’t mention this valve at all, it’s worth checking whether one is actually fitted. It’s a small, inexpensive part relative to the cost of the unit it protects, and every brand in this comparison references it as a required fitting, not an optional upgrade - Crompton’s own product catalogue lists a multi-function safety valve rated to 8 Bar as standard equipment across its entire storage range, the same “not optional” framing the other four brands use, even though Crompton doesn’t spell out in public terms what happens to the warranty specifically if one isn’t installed.

What else actually voids a geyser warranty

Beyond the MFV requirement, the causes that void a geyser warranty largely mirror what this site has already documented for appliance warranties generally, based on the currently published terms of Havells, Racold, and Bajaj:

Repairs by anyone other than an authorized service center or dealer. Every brand we checked treats this as an automatic disqualifier, not a judgment call - Havells’ terms void coverage for “un-authorized repair,” Racold’s for “unauthorized repairs,” and Bajaj’s terms state that repair “by any other person apart from the authorized dealers… shall absolve the Company of any warranty herein.”
Non-standard or non-genuine parts and accessories, even if a technician installs them competently.
Improper or non-standard installation - Racold’s terms name this specifically, and Havells’ terms make correct installation “as per instruction manual” a precondition for the warranty to apply at all, not just a void condition if it goes wrong.
Installing the unit in direct sunlight or where it takes regular water splashes - a condition specific to Havells’ terms, tied to the physical environment the unit is designed for rather than anything the owner does to it directly.
Water quality issues - scale, sediment, or damage from water pressure beyond the specified limit - covered under Racold’s terms and, separately, Bajaj’s exclusion for scale-related failures. This is the condition most likely to catch an owner off guard, since it isn’t caused by misuse in the usual sense - it’s caused by the water supply itself.
A missing, altered, or removed serial number, and, under Bajaj’s terms specifically, using the unit for any purpose other than what it’s “commonly used” for.

None of this requires memorizing every clause of every brand’s warranty card. The practical version is the same advice that applies to any appliance: call the brand’s authorized service line for repairs, even when a local technician could come faster, and don’t assume the small parts - the MFV, the anode rod, the flexible pipes - are outside the warranty’s attention just because they aren’t the tank itself.

Quick reference: geyser warranty checklist

Find your unit’s brand-specific tank warranty figure - don’t assume the number on the box applies without checking the warranty card, and don’t assume a brand’s registration scheme covers your geyser just because it covers that brand’s other products (Crompton’s does not)
If you own an AO Smith geyser, confirm whether you registered within 60 days of purchase, or whether an AO Smith-authorized technician did the installation - either one is required for extended tank/element coverage to actually be active
Confirm an MFV (multi-function valve) is actually installed on your unit - most brands’ terms void the warranty if it isn’t, and it’s a genuine safety device, not just a paperwork requirement
If you’re in a hard-water area, ask about periodic flushing and anode-rod replacement (where applicable) - scale-related failures are explicitly excluded from at least two of the five brands’ terms
Use only authorized service centers for repairs, for the full length of the tank warranty
If you own a Bajaj unit, note the unusually short 3-day window to report a defect if you want refund eligibility, not just repair
Keep the invoice and warranty card somewhere you’ll actually find years later, not just in the box the geyser came in
If a valid claim is ever refused, escalate in writing, then to the National Consumer Helpline (1915), then to e-Jagriti if needed

How Applimate helps

A geyser's tank warranty can run 7 to 10 years, but as this guide shows, whether that figure is actually active on your unit can depend on a registration deadline you'd have no reason to remember months later. Applimate is built to hold that record for you: the invoice, the exact purchase date, and the specific terms for your unit, all attached to the appliance itself rather than left to a 60-day window you'd otherwise have to track manually. (If you're storing this kind of document in any app, including this one, it's worth knowing what access that app actually needs - see Applimate's privacy policy for what that should look like: photos and storage access requested only for the specific feature that needs it.)

A geyser’s warranty card carries more genuinely distinct conditions than most other appliances this site has covered - a registration deadline that only one brand enforces, a safety valve that several brands treat as non-negotiable, and a hard-water exclusion that has nothing to do with how carefully you used the unit. None of that is unusual or unfair on the manufacturers’ part - it’s just detail that’s easy to miss when the only number you remember is the one printed on the box.
