Isn’t it surprising that a home water heater is an essential domestic appliance even in hot and humid Singapore? On dark, overcast early mornings, that welcome cascade of warm water helps you ease into a busy day. This is our list of the best water heaters in Singapore.

It includes energy-efficient models, those with innovative features, and options for every budget. Whether you’re looking for a tankless water heater or a traditional storage tank water heater, our recommendations will help you make an informed decision.

7 things to consider before buying a water heater

  1. Type: There are 2 main types of water heaters— storage tank and tankless. Storage tank water heaters are more common and store hot water in a tank for use as needed, while tankless water heaters heat water on demand.
  2. Size: For heaters with water tanks, a larger household will generally require one with larger capacity. Size is also a factor when you decide where to install it, as well as for its aesthetics.
  3. Safety features: Water heaters can pose safety risks, so look for models with features like temperature and pressure relief valves to prevent accidents.
  4. Energy efficiency: Water heaters with a higher efficiency rating will use less energy and save you money on your utility bills. The planet wins, too.
  5. Recovery rate: For storage heaters, recovery rate is how quickly the water heater can heat up a tank of water at room temperature. A higher recovery rate means that the water heater can provide hot water more quickly. A large household can use a smaller water heater if the device has a good recovery rate. Instant water heaters don’t store water and thus don’t have a recovery rate.
  6. Durability and warranty: Look for a water heater that is built to last and comes with a good warranty to protect your investment.
  7. Cost: Water heaters can vary significantly in price, with tankless models generally being more expensive. Consider your budget and long-term savings when making your decision.

We also considered styling in our review. After all, it’s not just how hot your water gets— just as important is how hot your bathroom looks with the water heater in it.
