240 L Frost Free Double Door 1 Star Refrigerator with Cool Pad for Extended Cooling & Spacious Fresh Zone(Moon Silver, HEF-251EGSA-P)

The maker's exact model code. Appliance marketing names are reused across capacities and star ratings, so the model number is the only reliable identifier when comparing listings.

Usable volume in litres. For refrigerators this is the gross figure, which counts space the shelves and fittings occupy, so the usable amount is lower.

India's Bureau of Energy Efficiency rating, from 1 to 5. More stars means less electricity for the same work, and the running-cost gap over a decade often exceeds the difference in purchase cost. Always read it with the rating year.

The year the star rating was issued. BEE revises its thresholds periodically, so a 5-star from 2018 can be worse than a 3-star issued today. Without this year the star count alone can mislead.

Electricity the appliance uses in a year under the BEE test conditions. Multiply by your tariff for a running-cost estimate; real use varies with how you set and run it.

Electricity drawn while running. It decides whether the appliance can run on an inverter or a generator, which the star rating does not tell you.

Whether the motor runs flat out and switches off, or varies its speed. Inverter types hold the temperature steadily and use less electricity over long runs, which is why they dominate higher star ratings.

The gas the cooling circuit uses. R22 is being phased out under the Montreal Protocol, so servicing it gets harder and dearer; R32 and R290 have far lower global-warming impact.

Operating noise in decibels. A difference of 10 dB is heard as roughly twice as loud, so it matters for a bedroom air conditioner or a washing machine in a flat.

How the refrigerator handles ice build-up. Frost free circulates air and never needs manual defrosting but uses slightly more electricity; direct cool is cheaper to buy and run but needs periodic defrosting by hand.

Whether compartments can be switched between fridge and freezer use, or cooling can be stepped down for a partly filled unit.

Whether the unit tolerates voltage swings without an external stabiliser, and across what range. It removes a real extra cost where supply is unstable.

Whether the appliance can be powered from a domestic battery inverter during a cut. High-draw appliances often cannot without a large inverter.

Whether the appliance can be controlled from the maker's phone app. App support can be withdrawn years later, which removes the feature from a working appliance.

How the appliance connects to a network and to other devices.

Width x depth x height in millimetres. Check it against doorways and the alcove the appliance must fit, and allow the clearance the maker specifies for ventilation.

The finishes this model is sold in.

What the maker covers and for how long, usually split between the whole appliance and its most expensive part. Compressor and motor warranties often run far longer than the general one, and that gap is the fact worth reading.

Whether the maker includes installation. For air conditioners this is a substantial separate cost, and additional copper piping is usually charged extra either way.

A link to the maker's own specification page for this exact model. It is the source a disputed fact here should be checked against, and it outranks any marketplace listing.

Which revision of the maker's spec page these facts were read from, as a date or version. Makers quietly edit spec pages after launch, so this records which wording was in front of us.
