Is a 3-litre geyser really enough for bathing in a small bathroom?

Yes, it can be, if you use a bucket or a low-flow shower. Instant geysers heat water continuously, so as long as the water flow is moderate, a 3-litre model works perfectly fine.

Which type of geyser should I prefer if my home has hard water?

AO Smith EWS Plus is a better pick as it has a Blue Diamond glass-lined tank that resists corrosion and scaling caused by hard water, which helps it last longer.

Why does my instant geyser turn off and on repeatedly while heating?

It is a normal safety function. That usually happens because of the thermostat automatically controls the temperature to prevent overheating.

Can I keep my instant geyser on for long periods in winter mornings?

There is no need to keep it on continuously. These geysers heat water instantly, so turning it on just before use saves power and keeps the element safe for longer life.
