Bajaj Flashy 3kW Tankless Instant Water Heater, White
The Bajaj Flashy 3kW Instant Water Heater is apparently “instant,” because who does not want to wait a few seconds for hot water while dreaming of a tropical shower? It comes in a sleek white finish, weighs a feather-light 1.4 kg, and promises high efficiency, because saving a few bucks on electricity is always thrilling. Its wall-mounted design makes it perfect for tiny bathrooms or kitchens where space is “precious,” and the smart electronics claim to keep the water temperature constant even if your flow changes. Of course, it only supports a maximum operating pressure of 12 bar, so if you live somewhere with unusually high water pressure, maybe enjoy lukewarm showers.

Great for singles, couples, or small families. Works well in apartments or high-rise buildings.
