NEW DELHI: Crompton's Juno 3-litre instant water heater is listed at Rs 4,600, against Rs 4,800 for the HydraJet 3-litre model. Juno is Rs 200 lower, while both carry a 3,000W rating. These are the manufacturer's tax-inclusive MRPs, rather than a local installation quotation. Price as of 30 October 2026, 00:53 IST.

The price gap does not change the core ratings
For someone comparing these names on a quotation, the striking detail is how much of the specification is shared. Capacity, electrical rating, pressure limit and external dimensions match. The official information gives no basis for describing the more expensive HydraJet as a larger heater or promising faster heating because of its price.
Both pages list a maximum temperature of 75 degrees Celsius, wall mounting and a stainless steel tank. Crompton also describes a plastic exterior and a four-level safety arrangement for each. These are manufacturer specifications; they do not establish how either appliance performs in a particular bathroom or at a particular incoming water temperature.
The two weight entries differ despite the matching dimensions. That is a useful reminder to read the individual model sheet rather than assume the products are identical under different names. It does not, by itself, tell us which unit is more durable, easier to service or better at keeping water hot.
HydraJet lists flexible pipes in the box
The HydraJet component list includes flexible hose pipes alongside the heater, mounting screws, instruction manual and warranty card. Juno lists the heater, screws, manual and warranty card, without naming those pipes. This is the clearest practical distinction in the published box contents, separate from their price and weight.
For an Indian household replacing a failed geyser, that distinction belongs in the installation conversation. Ask for the exact package description and an itemised fitting quotation. An accessory appearing in the box list does not establish that every connection, alteration or installation service needed at the property is included in the appliance MRP.
Equally, the absence of pipes from Juno's published list should not be turned into a made-up extra charge. The official pages do not quote such a charge. A fair comparison keeps the verified appliance figures separate from whatever an installer proposes for the actual location.
There is also a limit to what a matching pressure number tells a flat owner. It is a rating to check against the proposed installation, rather than evidence that either heater suits every building. Give the installer the model sheet and ask how the connection will meet its requirements. Do the same when replacing an older unit: keeping the old mounting position does not automatically answer questions about the new appliance's fittings or electrical connection.
Read the warranty by component
These listings divide cover between tank, element and complete product. That means the longest period displayed on the page should not be read as the duration for every part. Keep the model name on the bill and the warranty card together so a later service request identifies the product and the component involved.
The same discipline helps when comparing with storage heaters. Our existing Crompton Amica Pro price list covers a different family. The Arno Neo guide and Solarium Qube price list provide other reference points without treating their prices as interchangeable with these instant models.
For this pair, the official comparison is unusually close: the premium changes the published package contents, but not the headline capacity or element rating. That makes the exact model and supplied fittings more informative than a broad claim that the dearer geyser must be more powerful. Neither listing supplies a measured household running-cost comparison.
