In Singapore’s hot and humid climate, you might not think much about hot showers — until the rainy season arrives or your water heater stops working. Whether you're upgrading your bathroom, moving into a new home, or simply replacing a faulty unit, choosing the best water heater Singapore can significantly impact your daily comfort, energy bills, and even bathroom aesthetics.
With countless brands, types, and features available, selecting the right water heater may seem overwhelming. In this comprehensive guide, we’ll walk you through the best water heaters available in Singapore in 2025, what to look for, and where to get them.
Types of Water Heaters in Singapore
Before diving into our top picks, it’s important to understand the two main types of water heaters commonly used in Singapore:
1. Instant Water Heaters
Instant heaters are compact, mounted on the wall, and heat water on demand. They are energy-efficient since they don’t store hot water and only work when turned on. These are ideal for smaller bathrooms or homes with limited hot water needs.
2. Storage Water Heaters
Storage heaters come with a tank that heats and stores hot water for later use. While they take up more space, they provide a consistent flow of hot water — especially beneficial for larger households or those who enjoy long showers.

Factors to Consider When Buying the Best Water Heater in Singapore
✅ Space Availability
For HDB and condos, space is limited. Choose slim, wall-mounted heaters or compact instant models to save space.
✅ Family Size
Larger families benefit more from storage heaters to ensure a steady supply of hot water. Smaller households can do just fine with instant models.
✅ Water Pressure
Instant water heaters typically require low water pressure, while some storage models may need higher pressure. Always check compatibility with your home's plumbing.
✅ Safety Features
Choose models with built-in thermal cut-offs, anti-scald protection, and pressure relief valves. Safety is non-negotiable.
✅ Energy Efficiency
Look for energy-saving certifications or features like smart timers, temperature control, and insulation. These can lower your utility bills over time.
Installation and Maintenance Tips
Hire Licensed Installers: In Singapore, it’s required by law to use PUB-licensed plumbers and EMA-certified electricians.
Regular Servicing: Especially for storage heaters, schedule maintenance every 2-3 years to prevent sediment build-up and prolong the unit’s lifespan.
Check Warranty: A good warranty period (usually 5 years for the tank and 1-2 years for parts) is a sign of quality and after-sales support.
