  4. 4.Should I buy a heater with a thermostat control?
  5. 5.What safety features should I look for?

1What's the difference between instantaneous and storage water heaters?

Instantaneous heaters heat water on demand and take up less space, making them ideal for apartments, while storage heaters keep a tank of hot water ready but need more installation space. Storage heaters are better if you have multiple bathrooms or high simultaneous usage, whereas instantaneous suits smaller households or single-bath setups.

2What capacity (in litres) do I actually need for my home?

For a single person or couple, 25-50 litres works fine; for families of 3-4, aim for 50-80 litres; larger households may need 100+ litres. Consider your shower duration and whether multiple people shower around the same time to avoid running out of hot water.

3What wattage or power rating matters for fast heating?

Higher wattage (3000W+) heats water faster, but requires a stronger electrical connection and costs more to run. Lower wattage (1500-2000W) is gentler on your electrical system and bills, but takes longer to heat a full tank—choose based on your home's electrical capacity and how quickly you need hot water.

4Should I buy a heater with a thermostat control?

A thermostat lets you set and maintain a specific temperature, preventing scalding and reducing energy waste, making it worth the extra investment. Budget models without thermostats are cheaper upfront but harder to control and less safe, especially if you have kids or elderly family members.

5What safety features should I look for?

Essential features include a pressure release valve (prevents tank rupture), overheat protection, and a thermostat with a temperature cutoff. Also check for a leakage detection switch and ensure the heater has proper grounding and certification marks for electrical safety.
