IoT Geysers? Racold or Havells

Reviewers review it well but it has a lot of complaints on the e-commerce platforms. Also not sure if it offers the 7+4+2 warranty that other brands do. Normally that is cut on the cheaper options.

The general recommendation is to get ones with Incoloy heating elements which I believe the cheaper ones don’t have.

Also there are service complaints with nearly all the brands but AO Smith seems to have the most and somehow manages to be noisy.

Yeah.. going through different sites and different reviews, I guess I’ll skip this. Checking the Havells Adonia Spin. Seems to come with the same 7+4+2 warranty. Other than the digital temperature display and remote control that come with the Adonia R, there seems to be no major difference between the two. Price is almost 3k lesser for the Spin.

Getting Racold CDR DLX 35L, for 9000 to 9200 offline, including free installation but will need to reconfirm. No online platform is able to beat this offer.

Any specific reason you are looking for a 35L geyser? Especially since it is a 2kW appliance, wouldn’t it take much longer to heat?

Seems it is less than 9k after bank discount on Croma and Flipkart, so not sure why you are saying the offer is unmatched.

2kW is recommended for 15l, most 25l ones step up to 3kW to retain the same heating time.

Updating the thread, I would advise everyone to stay away from IoT geysers and instead go with an offline one.

My Adonia I 25L geyser suffered with an issue in which its internal mcb tripped whenever I set its temperature above 60 Celsius. This was due to non updated firmware which became a nu-sense on its own. The service guy obviously had no clue what so ever and tried to order new MCB etc. as a replacement. But even then issue remains only to be rectified by the firmware update which was random and optional.

So my advice would be to stay away from a tech that causes more pain than gain.

I had purchased the Adonia R initially and then read more reviews where nearly all issues within 3 years came from the PCB. Switched to the Adonia Spin after that which is basic enough to not have the same issues.

But agree with your point that nearly all the IoT geysers seem to suffer from the PCB issue.

Still cant see cdr dlx <9k anywhere. Got cdr dlx plus (display meter) for 9.5k offline (incl free installation, pipes etc). Lets see if it is free-free or part free.

This will be replacing older 35 liter installed at wife+kid bath, they dont want change and want ready supply of hot water during northern winters. OTOH Crompton 25 Liter in my bath feels inadequate and in the end I have to make do with not so warm water.

Everybody uses shower so need higher capacity.

Few months ago seen on AZ, hindware Atlantic Evano 50L Horizontal 50L for around 5-6k. Did not go for it as felt some kind of scam.

Get this 50 litres water heater: Racold (PLATINUM NXT-50 V, White) on Flipkart

https://dl.flipkart.com/s/t9IqErNNNN

Installed, the service including 2 pipes and wall fasteners was free. Removal of old geyser if any is chargeable.

The service feedback is bad for all the companies but I usually don’t experience that in Mumbai. However, Havells took nearly a week to do the installation. Seems the first 2 guys were just ignoring the requests for whatever reason but the third guy was quite responsive.

Tried the usual, is installation charged covered thing at the end which of course was. However, I shifted from a horizontal to vertical geyser and the pipes provided were just too short to install in the alternative location.

The installation guy told me I can get it done later by anyone but I got him to get the 2-metre company pipes later and complete the installation, though of course he pocketed extra money for that.

Since the hot water is always mixed with cold for the shower, 15L is more than good enough and it takes about 10 minutes to heat the water.

I have been using racold onmis wifi for 3 years and it needs thermostat replacement every season. Iot geysers are complex and the part availability will be hard. The thermostat and pcb is main part of my geyser and it costs 2500rs every season. Also racold service in my area is ultra poor. Better go for normal geyser and use it with smart plug. Normal geyser use generic parts and can be easily repaired and can last for 6 yrs or more .

There are 2 types of heaters in the market .

  1. Direct element heating .
  2. Indirect heating

With direct element heating - the water quality is important and if the water is salty not advisable . The salt can corrode the heating element fast and chances of shock is also very high .

Indirect heater elements are much better suited for hard water , no chance of any shock but are not so efficient .They are also costlier due to copper tank .

3kw direct heating element is the best but again wiring also needs to be beefier enough .

These are the basics before you buy a water heater .

Hey, I’m looking at 4 qty AO smith 25L water heaters. Can a 3kw water heater run on 2.5mm thick wire? Or will it need 4mm wire?

Technically 3.5kw (assuming starting load to be higher than rated load), is 15.9A.

So it shud run. But unaware of wiring at your place il recommend to stick to a good 2kw geyser like Ao smith full abs square body geyser

@sato1986 Thanks for the reply. I’ve 2kw 15l racold geyser and am not satisfied with the shower experience (hot water runs out before the last part of shower).

I’ve used Polycab and Finolex PVC FR grade (nor FRLSH) for wiring. The wire run is 25 meters and has a dedicated MCB.

I think a 25l geyser can fix the shower experience and 3kw will reduce the waiting time for water to heat up. My electrician says that 3kw geyser should work fine with the current wiring, but I’m trying to get a second opinion.

I’m looking at this particular model. Amazon.in

3000w/250v = 12A + adding 25% buffer = 15A. My wires are in conduit, not sure how much to factor for efficiency loss for 25m conduit wire run.
