Types of Storage Water Heaters

Electric Storage Water Heaters

Households in Singapore frequently have electric storage water heaters. To provide a steady supply of hot water, they heat water that is kept in a tank using electricity. These heaters are reasonably priced and need little maintenance.

Gas Storage Water Heaters

Gas storage water heaters use gas to heat water in a tank. Though less prevalent, they are incredibly effective for bigger houses. Proper ventilation and a steady gas supply are necessary for these heaters.

Digital Storage Water Heaters

Digital storage water heaters provide modern features such as a thermostat panel, which allows for exact temperature control. These heaters are commonly found in luxurious residences and niche businesses.

Active Solar Water Heaters

These solar water heaters use solar panels to capture the sun’s energy to heat household water in the storage tank. This is an eco-friendly way of providing domestic hot water, with a significant saving on the energy cost.

The Heat Pump Water Heaters

This water heater is likewise driven by electricity, but the heat is produced in a separate device before being pumped to the storage heater tank, as the name indicates.

Types of Instant Water Heaters

Electric Tankless Water Heaters

Instant water heaters, or electric tankless water heaters, heat water just when needed and don’t store it. They are perfect for smaller houses and HDB apartments since they are energy-efficient and compact.

Digital Instant Water Heaters

They provide precise control over the temperature; therefore, these are the best in modern homes and condos. They deliver hot water so fast.

Gas Instant Water Heaters

Gas instant water heaters heat and deliver hot water instantly by utilising gas. Used extensively in industrial applications, these can also be installed in residential properties to access hot water with instant heating.

Common Storage Heater Problems

Energy Loss

If hot water is not utilised right away, storing it might result in large energy losses. Higher energy use is the outcome of this.

High Running Costs

Heating a significant amount of water requires much energy to heat it, particularly if hot water is kept overnight.

Water Temperature Problems

If the capacity of the storage heater is less than the required amount of water to be heated, then there are chances that the water will not be adequately heated.

Temperature Shock

Sensor problems can cause fluctuations in temperature in automatic storage heaters, which may hinder their heating efficiency.

Common Instant Heater Problems

Initial Cold Flow

Instantaneous water heaters are ineffective in delivering hot water initially because it takes some time for the water to heat up while flowing through the heater.

Abnormally Heated Water

If the temperature is set too high, the water can become dangerously hot.

Noise Emission

Older instant heaters may emit noise due to wearing out; they may, therefore, need some repairs or replacement.


Instant heaters are prone to leaking due to pressure, corrosion, or overheating. This can be prevented by regular water heater repair.

Discoloured Discharge

Corroded heating elements lead to rust and mineral accumulation in a heater, which causes discoloured heated water.
