Havells Water Proof Immersion Water Heater HB 15 1500 Watt (White Blue)

In this product has large three pin . Build up quality is too good. Water heat faster in the comparision of gas oven.

Immersion heaters have changed very little in terms of features or design over the 40 years or so I’ve been using them. And regardless of which brand name is stamped on them, they look like clones of each other. It was therefore with some excitement that I bought this Havells model that had at least three novel features: an auto-cut-off facility, a temperature control knob, and a protective plastic cover for that part of the heater users could come into accidental contact with. But quite a bit of my excitement drained away when the heater arrived. I couldn’t use it straightaway because it has a cord that’s barely a metre long, and it just couldn’t reach the 16A socket it needs to be plugged into. Such heavy-duty sockets are normally positioned high in most bathrooms, so that they are easily accessible to any storage water-heaters that may be installed. Havells should have made allowances for this and added at least another foot-and-a-half to the cord length. For a large-scale manufacturer, this extra length would have made little difference to the production cost. The product, anyway, is priced a couple of hundred Rupees more than other 1500W heaters (the MRP being even higher, at Rs1000).

In my case, therefore, the heater had to be ‘accessorized’ before it could be used: I had to buy a stool that would raise the the bucket off the floor, and thus compensate for the shortness of the cord. And no, it can’t be any stool lying around in your home: it has to be a stool of a certain height, about 14 inches for me. Any taller, and the bucket can’t be accommodated under the tap; any shorter, and you begin cursing Havells again for their miserliness with the cord. The stool took two days to arrive, and I ‘inaugurated’ the heater a full four days after it was delivered. Thank God my old immersion heater was still usable, in spite of its heavily calcified condition.

There is yet another problem with this heater: though it helpfully allows you to choose between three temperature settings, you don’t know what value each setting corresponds to. What does ‘high’ temperature mean — 60 degrees Celsius? Seventy? I found out the hard way when I set the temperature high, and the heater wouldn’t switch itself off for 15 minutes, which is five minutes longer than the time my old heater takes to heat up some 20 litres of water. And by then, the water had turned scaldingly hot. I tried the ‘medium’ setting the next day, and again had the nasty experience of having to deal with extra hot water. Perhaps the right setting is ‘low’ then. I’m not sure. Neither the product literature that came with the heater nor the Havells website has any information that will help you choose the right setting, and stop you burning yourself.

So both the innovative features of this heater that made me buy it — the variable heat setting and the auto-cut-off
— ultimately turned out to be quite useless. I still have to depend on my instinct, and on my experience with my old ‘featureless’ heater, and manually turn the heater off when I think it’s done its job.

I have a question for other users of this product, or for the manufacturer: can the temperature be set to in-between values, something between ‘low’ and ‘medium’, for instance. The way the controlling knob is marked, with several lines between the presets, suggests this is possible. Or maybe that’s yet another ‘useless’ feature of this fancy heater. More trial-and-error? But should such a basic piece of equipment be so difficult to use?

Update
After a week’s use of this heater, I’d like to add a word of caution for the benefit of other buyers and users. Since the heater has its own indicator light, which switches off at the set temperature, you may forget to switch the socket switch off, particularly if the switch is away from the socket, as in some contemporary bathrooms that have all switches bunched together at the bathroom door. If you forget to switch the socket off, and, in the meantime, have removed the heater from the bucket, it will begin to heat up again once the temperature has fallen below the set value. This dry-heating will damage both the heater and wall, if you’ve hung the heater up. But, more significantly, it will also be extremely hazardous if your body is wet, and there’s no one around to switch the socket off for you. This happened to me twice. Call me dumb, if you want to, but please be careful.

But slowly slowly water hitting

Product is good but wire very short so I advise to company for improvement
