Understanding the Two Main Types of Water Heaters

Instant Water Heaters: Quick and Compact

Instant water heaters, as the name suggests, heat water on demand. There is no tank involved, so water flows through a heating element and gets heated instantly.

Best for:

• Small families or individuals
• Kitchens and single-bathroom homes
• Places with limited space

Key Advantages:

• Instant hot water with no waiting time
• Compact design saves wall space
• Lower initial cost
• Reduced heat loss (no stored water)

Things to Consider:

• Limited flow rate (not ideal for multiple outlets)
• Higher power draw during use
• Not suitable for bathtubs or rain showers

Storage Water Heaters: Consistent and Powerful

Storage water heaters come with a tank that stores heated water for later use. They are commonly found in homes with higher hot water demand.

Best for:

• Families with multiple bathrooms
• Bathtubs and rain showers
• Homes with predictable usage patterns

Key Advantages:

• Consistent water temperature
• Can supply hot water to multiple taps
• Works well with low water pressure

Things to Consider:

• Requires more space
• Higher upfront cost
• Heat loss over time if not insulated well

How to Choose the Right Capacity

Capacity is one of the most important factors when selecting the best water heater.

Recommended Capacities

• 1–3 Liters: Kitchen use
• 6–10 Liters: Single bathroom (instant)
• 15–25 Liters: One bathroom (storage)
• 25–50 Liters: Multiple bathrooms or bathtubs

Choosing the wrong capacity often leads to dissatisfaction either running out of hot water or paying more than needed.

Power Consumption: What Impacts Your Electricity Bill

Power consumption depends on:

• Heater type (instant or storage)
• Wattage rating
• Daily usage habits
• Insulation quality

Instant Water Heater Power Use

• Consumes high power (3–6 kW) but only while in use
• Ideal for short-duration needs

Storage Water Heater Power Use

• Uses lower power (1.5–3 kW)
• Consumes energy over a longer period to maintain temperature

Smart Water Heater: Is It Worth It?

A smart water heater is not just a luxury, it can be a smart investment for modern homes.

Smart Features to Look For
