Quick Tips on Buying a Water Heater in Singapore

If you don’t have time to read through this entire guide, this section serves as a quick summary for you. Do check out the next section where we share a summary of the best water heater brands in Singapore and the models to buy. 

  • Type of water heaters
    • The first step is to decide which type of water heater to buy. There are two types, storage water heaters, and instant water heaters.
  • Amount of space available
    • You will want to consider your space available. Do you have a space to place a tank? If your space is limited, an instant water heater will be best. 
  • Capacity
    • How much hot water do you need for your household? Storage water heaters can hold quite a fair amount of water, but it is a limited supply. If you have a huge household and wish to take back-to-back showers, instant water heaters might be a better option because it will not run out. 
  • Lifestyle and preferences
    • If you wish to take showers with strong water pressure, a storage heater would be more suited. Also if your bathroom aesthetics matter, a storage unit can be concealed. Note that if you want hot water in your basins, kitchen sinks and more, only a storage heater can do that. 
  • Budget
    • Storage water heaters may cost more upfront to purchase and install, but they last longer (10 years or more) than instant water heaters (5 to 7 years) and they can service multiple bathrooms. Depending on the number of bathrooms you want to install, your cost between the two options can even out to be about the same ($500 – $600 per home for 2 bathrooms). But if you are on a tight budget, instant water heaters have lower-end models that cost less than $100
    • I suggest buying the best model you can afford, for this is an item that you will want to last the years. 
    • The cost of a storage heater will start from $200 and go upwards to $500 or more, depending on the model and capacity. An instant heater is cheaper and you can get a good unit from $100 – $200. The cost of installation is separate from the unit purchase. Note that a storage heater can service multiple bathrooms whereas an instant heater can only service one. 
    • The cost of installation will average from $80 to $200, depending on the complexity. Make sure to find a reliable plumber/handyman to help you with the installation. Do not attempt to do it yourself. 
  • Brand
    • Buy your water heaters from a reputable brand. The top 3 brands in Singapore are Ariston, Rheem, and Joven. 707, Champs, Rubine, and Rinnai are also considered good brands.

Types of Water Heaters

Instant water heater

water heater installed in bathroom

Like its name, an instant water heater heats water at the point of time you need it. There is no tank to hold the water. The water instead is heated as it flows through the unit’s heat exchanger. It is usually installed in the bathroom and you can see the unit just next to the shower system. It is best used as a single-point heater (one for each bathroom) and can only heat up the water to your shower (not the sink). 

Instant water heaters are more energy-efficient as it offers on-demand heating. However, there are also pros and cons of this model, with water pressure and aesthetics being the main concerns. 

Pros: 

  • Relatively inexpensive to install. You can buy and install one for less than $200.
  • On-demand water heating, so you do not need to worry about hot water running out
  • Energy is only used when the heater is being run 
  • Compact and does not take up much space (compared to a storage tank)
  • The water might not be as hot 
  • Easy to install, maintain and replace 

Cons

  • Only able to power a single shower
  • The unit is installed in the toilet and will affect the aesthetic of your toilet. You will see that luxury hotels do not have instant water heaters placed next to their shower. That being said, there are nice-looking water heaters in Singapore like Ariston (Rinnai and Toshiba). But if you want inbuilt water fixtures, it is unlikely you will go with the instant heater. 
  • Water pressure is lower due to the flow restrictive that allows the water to be heated as it passes through the heater. Though some instant water heaters in Singapore come with a “boost” function, it is not very effective and usually noisy. An instant heater is unlikely to be able to power rain showers.
  • Water temperatures are inconsistent, as it is dependent on the flow rate. That being said the Rubine Instant Water Heater with Rain Shower Set RWH-3388 and Ariston Aures Luxury ST33 is said to not have this problem
  • Usually only able to power hand showers due to limited flow rate. That being said, I use the Rinnai and one model comes with a rain shower extension. It works relatively well though the rain shower is not very strong it has good coverage and is sufficient for home use. 

Recommended Instant Water Heater in Singapore:

Rubine Instant Water Heater with Rain Shower Set RWH-3388

rubine instant water heater

Instant and effective water heater with rainshower

The Rubine BOW Rain series offers a minimalist design that blends in with any bathroom style. Both matte black and classic white versions of the RWH-3388 instant heater are sleek and slim, which takes up little space in your bathroom if space is a concern. We personally have this water heater installed in our bathroom, and I thoroughly enjoy the rainshower experience.

What’s great about the Rubine RWH-3388 is that it offers a variety of water pressure and functions. It comes with an overhead rain shower that perfectly mimics the feel of raindrops, a hand shower with five settings for different water pressures, and a tri-way diverter that provides hot water to the overhead shower, hand shower, and the spout.

Cost-effective and powerful

What we love about the Rubine RWH-3388 is how both its rain and hand showers are designed to be water-saving, and its heater unit reduces up to 55% of energy cost. The inverter DC pump can boost the water pressure despite fluctuations in water flow, and the UK technology heating element (UL-approved standard) heats up water quickly and efficiently.

Safe and quiet

Moreover, the independent thermo cut-out and safety thermostat of RWH-3388 prevents the water from overheating to scalding temperatures, keeping you safe from any accidental burns. Lastly, the low noise inverter DC pump operates quietly at <45db, allowing you to enjoy a peaceful showering experience. 

Why buy this:
  • Sleek & slim minimalist design
  • Water-saving overhead rain shower & hand shower with 5 different water pressures
  • 55% reduction in energy cost
  • Very efficient heating element and anti-scalding protection
  • 1-year warranty for parts & 5-year warranty for the heating element and inner tank

Storage water heater

storage water heater singapore

This is the traditional type of water heater that typically looks like a cylindrical tank (though there are more modern shapes and designs now). The water in the tank is kept at a constant temperature. The storage heater releases hot water from the top of the tank, and cold water enters from the bottom of the tank to be heated again. This means that you will always have hot water anytime you need it. 

A storage water heater is useful to supply hot water to the entire house (whereas instant can only supply hot water to 1 shower outlet). If you want hot water in your sinks and kitchen basin, you need a storage heater. It is generally a more reliable option in terms of water flow and consistent temperature. That said, it does have its pros and cons, of which a more complex installation is of concern.

Pros

  • A storage tank can supply hot water to the entire house (not just bathrooms, but also your basins and the kitchen sink) 
  • Consistent temperature 
  • Can be placed out of sight 
  • Allows a high-pressure flow of up to 10 litres per minute
  • Can power any type of shower, from rain showers to massage jets to bathtubs
  • Longer life expectancy (10 years or more) 

Cons:

  • The tank is bulky and takes up space
  • Slightly more troublesome and more difficult to install compared to an instant heater 
  • Higher cost (but can serve more than one toilet) 
  • Limited supply – make sure to choose the right tank capacity for your household
  • Take up a fair bit of energy (gas/electricity) as it heats up the entire tank

Xwell Classic Plus Electric Storage Water Heaters

Rheem Singapore - Best Water Heaters in Singapore

Designed to improve the quality of your shower

Are you someone who enjoys a relaxing experience of a hot and soothing shower? Be it for chilly mornings or after a long, tiring day, a hot shower definitely feels like a huge relief as it helps to flush out the toxins that got trapped in your skin all day and also alleviates the muscle tension in your body. With Rheem’s Xwell Classic Plus Electric Storage Water Heaters’ extensive range of features, you can elevate the quality of your showers.

Rheem’s Xwell Classic Plus Electric Storage Water Heaters are fitted with an exclusive RheemFoam™ insulation, a high-density and top-grade polyurethane foam that provides 16% more heat retention. This means that water remains hot for a longer amount of time in the inner tank, leading to reduced heating cycles. They are also equipped with the RheemHot+™ Diffuser which regulates the incoming flow of water into the tank so that heating is optimised, resulting in 45% more hot water for your hot showers. With less waiting time and more hot water, your showers will be much more enjoyable, be it on a rushed morning or on a tiring night after a busy day.

Safe for the entire family

While taking hot showers is a relaxing and comfortable experience, there may be the fear of scalding especially if you have children or elderlies at home. With Rheem, you can enjoy your warm showers and baths with peace of mind. The Xwell Classic Plus Electric Storage Water Heaters are equipped with a RheemSafety feature that automatically stops the heating process once the temperature of the water reaches a predefined temperature. This way, you and your loved ones can shower in ultimate comfort without having to worry about anyone getting scalded by hot water

Built to last 

Naturally, when buying home appliances, you would want to invest in something that is durable and reliable. Rheem’s Xwell Classic Plus Electric Storage Water Heaters do not disappoint in this aspect. They are built with a RheemHD+™ sacrificial anode rod that is placed inside the water heater tank. The sacrificial anode rod allows aggressive water to attack the anode rod before the walls of the inner tank, so if corrosion were to happen, it would occur on the anode first. This is a good thing because anode rods are much easier to replace as opposed to a leaking tank! 

Moreover, the inner walls of Rheem’s Xwell Classic Plus Electric Storage Water Heaters are coated with a RheemGlas™ virtuous enamel glass lining coating to provide added protection against corrosion. With both the sacrificial anode rod and durable glass lining coating in place, you and your family can enjoy years of relaxing, rejuvenating and revitalising warm showers.

Get the right capacity for your household needs

When choosing a storage heater, make sure to get the right capacity for your household. Alternatively, you can choose a smaller capacity but avoid taking back-to-back showers. A bigger capacity will take up more energy to heat. An 8 -10-minute shower will take about 60 – 70 litres of water on average with a medium-flow showerhead. As a guide, you will pick the capacity depending on the number of people in your household. 

  • 1 person: >30 litres
  • 2 – 3 persons: 30 – 40 litres 
  • 4 – 5 people: 40 – 50  litres 
  • 5 people or more: >50 litres

Storage vs Instant Water Heater: Which should I choose? 

I have both a storage water heater and an instant water heater installed in my home. 

My two main bathrooms are powered by the storage heater (this was done during my home renovation so it was easy to conceal). My spare bathroom uses an instant heater (I had this done after I moved in). They both work equally as well, each with its own advantages. 

Choosing between storage or an instant heater to power your home is dependent on your needs and lifestyle preferences.

Lifestyle preferences

  • If you want hot water in your basins and kitchen sink, only a storage heater is able to do that.
  • If your bathroom aesthetics are of concern, and you prefer built-in water fixtures, you should opt for the storage unit.
  • For very hot showers, powerful rain showers, or soaking in the bathtub, an instant heater will not be suitable as the water flow and pressure is limited.
  • But if you are simple, and just want something that is easy to install and works alright, you can opt for an instant heater.
  • It also depends on whether you are staying in a house or a flat. If you are staying in a 2-storey house you might opt to do both – a storage heater for the top floor bathrooms and an instant heater for the spare bathroom, like what J Babies did.

Cost-wise, if you are buying a water heater for a new home (2 bathrooms), it will work out to be pretty much the same cost (about $500 – $600) for the purchase of the unit and installation.

You can refer to this summary table for the list of pros and cons between storage and instant heater.

FAQs & Installation

How much is it to install a water heater in Singapore? 

The cost of installation of an instant water heater will average between $80 to $150. 

What does the installation require? 

You will require both a water point and an electrical point for the instant heater to work. 

Where do I install my water heater? 

For an instant heater, it will be installed in the bathroom next to your shower. It will be connected to water and electricity points. As it is compact, it can fit in almost any bathroom. 

rainshower and heater

A water storage heater, on the other hand, is bulky and heavy. You can install it in the bathroom ceiling and have a false ceiling to cover it from sight. 

For HDB Built-to-order flats, usually have a designated place for the storage water heater. 

How long will the installation take? 

Generally, instant water heaters are easier to install than storage water heaters. When I installed my instant heater in our third bathroom, it took less than an hour. The handyman simply fixed the heater and shower on the wall. He then connected the electrical point via the ceiling so the switch for the heater could be placed outside the toilet. 

For a storage heater, the installation will take longer as the handyman will need to connect the heater to 2 or more bathrooms, which means that the water pipes will have to be connected between the bathrooms. The storage heater also usually requires a bracket to hold it up (if it is not standing). This process might take several hours. 

Replacing an old heater would be more straightforward as the connections are already there. 

Can I install my own water heater?

Unless you are an experienced plumber, the answer is no. Installing a water heater requires proper expertise and experience. A heater involves both water and electricity, which can be unsafe if not properly installed. Always seek a highly-trained plumber or handyman to install your heater. 

How is a water heater installed? 

I will usually leave it to my professional plumber, but if you are curious, here are the steps to install a heater.

  1. Turn off electrical power
  2. Remove old heater (if doing a replacement) 
  3. Disconnect supply cables and pipes
  4. Position new heater to match the water inlet
  5. Screw holes to hold up the heater
  6. Position and fix the heater on the wall, and connect it to the water inlet 
  7. Connect the electric supply and water supply to the new heater (if first time installation, this needs to be set up) 
  8. Check that it is filled with water, and switch on the power
  9. Test out the heater and check for any leakages

How long does a water heater last? 

The life expectancy of an instant heater is about 5 to 7 years. For a storage heater, it should last about 10 years or more. Getting it properly installed will ensure that your heater lasts long. 

For proper maintenance, flush the storage heater every 5 years. For instant water heaters in Singapore, check the wiring every 3 – 5 years. 

When do I need to replace my water heater? 

If your heater has turned yellow on the outside, or if you find problems with it, you can either get it repaired or replaced. 

Below are some common problems that you may face with old water heaters in Singapore: 

  • Inconsistent water temperature: If the temperature of the water is inconsistent, there might be an issue with the thermostat. Do check with a plumber on this issue and do not try dismantling it yourself to check. 
  • Weird noises: If your heater is making weird noises, it might be cause for concern. This might be due to sediments building up over the years. This will cause the heater to be inefficient and take more energy to heat the water. 
  • Water leakage: If your heater is leakage, this might be due to cracks or loosened water piping. Do check with a plumber. 
  • Rusty: If the water coming out from your heater is brown or weirdly coloured, this could be a sign of rustiness inside the heater. Water heaters in Singapore are generally noncorrosive, but overtime can deteriorate. If you find that the water is murky, do replace your heater. 

Should I replace my water heater? 

For an instant heater, if it is past its life expectancy and has issues, I suggest getting it replaced as an instant heater might cost the equivalent to repair. 

For your storage heater, it depends on the problem as the cost will be higher. 

A replacement job will cost about $80 – $100 and might be more during weekends. 

A repair job will cost about $30 – $50 for transport and service fees. Depending on the severity of your problem and the materials required for repair, the cost will differ. If you choose not to repair, you will incur the transport and service fee. Usually, if you choose to repair, the transport and service fee will either be waived or subsidized into your total cost. 

Where to buy a water heater in Singapore?

You used to only be able to buy a water heater in Singapore from stores, but now you can purchase them online for the ultimate convenience and even enjoy discounted prices! Shopee and Lazada are my go-to for shopping electronics. If you prefer to see the water heaters in-person, you can always pop by any of the consumer electronics stores like Best Denki, Courts, Harvey Norman and Gain City near you to check it out before purchasing online. 

How to finance your home purchase?

If you would like to take up a loan for your home purchases, consider a personal loan, as renovation loans do not give you the cash upfront. You can find the best personal loan suitable for you on Singsaver.
