Types of water heater

There are generally 2 types of water heaters in Singapore, namely: Storage Heater Tanks and Instant Water Heater.

  • Storage water heaters – Storage water heaters are unique in the sense that it has a tank to store water to be heated up and then dispensed when needed.
  • Instant water heaters (a.k.a tankless water heaters) – Instant water heaters heat up water instantly and do not store water, unlike storage water heaters.

These water heaters can be further categorized into other categories depending on what it is powered by.

Types of Storage water heaters

  • Electric Storage Water Heaters – Fueled by electricity, these are the most common in most apartments in Singapore. Typically, in Landed properties or Condos, these water heaters have a tank wherein water is stored and heated to a set temperature. They are affordable and easy to maintain. They are however prone to leaks and high energy usage.

  • Gas Storage heater – A gas storage heater heats the water in the tank by burning gas. Compared to electric storage heaters, gas water heaters are less common in Singapore and are mostly used by Landed homeowners. It requires a constant supply of gas for it to function.

  • Digital storage heater – Powered by electricity, these high-end water heaters and a luxury item that can heat your water up to the temperature you desire with its thermostat panel. Although not as common as other water heaters, these are usually found within specialised industries and landed properties.

  • Heat pump storage heater – This water heater is also powered by electricity except that the heat is generated in another device before pumping it to the storage heater tank, thus the name implies.

Types of Instant water heaters

  • Electric tankless water heaters or Instant Water Heaters – These heat water when needed so they are more energy-efficient than storage water heaters. There are 2 types of such heaters: Single point and multi-point. The main difference is the water passing through its ports, either a single point or multiple points. They also fit in small spaces and maintain a constant stream of hot water without wasting energy. This makes it popular with HDB flat owners. Instant heaters mostly come with an attached showerhead. It can even come with a different function that can control the flow of output for your shower experience. Depending on the model, you can even customise the showerhead to suit your preference.

  • Digital instant heater – Similarly to digital storage heaters, this device heats up the water accurately, but in an almost instantaneous format. Like its counterpart, these are luxurious household items usually located in Condominiums.

  • Gas instant heater – Heats up water with the use of gas. This gas instant heater is mostly used in the industry to heat up water instantly, although household use can still be seen.

Water heaters can be placed anywhere around your home. It is up to the homeowner to decide where to install the water heater. However, bulky water heaters can only be installed in places with more space. Take water heater tanks for example, due to their big and bulky appearance, it needs to be installed in places like above the false ceiling, hidden in a cupboard, or even remain exposed hanging above the water. As for instant water heaters, they are compact and can be installed almost anywhere near a water source and electric powerpoint.

Things to consider before purchasing a new water heater

If you are looking to install a new water heater in your household, do keep in mind the following key points.

  1. Types of water heater

As explained above, there are many types of water heaters with unique capabilities. But you mainly have to decide between a storage water heater or an instant water heater. As for the type of source to power your heater, you will have to decide based on your preferences and other aspects such as convenience and type of use. Consider which would be the ideal water heater for yourself and your family.

  1. Cost

Being wallet-conscious can be a dormant trait that most adults will have. So, it is of no surprise that you would want to look for the best value water heater to fit your budget. Storage heaters are generally cheaper to install compared to instant water heaters. However, storage heaters would be ideal for family usage.

  1. Installation location

Depending on your place of residence, you may choose instant water heaters over storage water heaters. For example, if you live in an HDB flat, you will most likely go with an instant heater due to the fact that an instant water heater is compact and use up less space than compared to a big and bulky storage heater tank.

  1. Energy consumption

Energy consumption may be a factor that you want to keep in mind. If you are utility bill conscious and have a budget set aside for it, you may want to consider using water heaters which are more energy efficient, which means that it uses less energy for the same amount of output.

  1. Life cycles & Maintenance

On average, instant heaters have a lifespan of 10 – 15 years whereas storage heater tanks have a lifespan of 8 to 13 years. It is advised by our professional plumbers to get the instant heaters checked and maintained every 3 to 5 years and every 5 years for storage heater tanks.

  1. Warranty

Different water heaters have different periods of warranty. For instant heaters, the manufacturer will usually provide a 1-year warranty on parts, but it varies from the brand. Storage heaters have a warranty period of 3 to 10 years for the parts provided by the manufacturer, which also varies by brand.

Common water heater problems

Like every other electronics and commodity, water heaters will encounter issues in the long run and will need to be repaired or even replaced. When it comes to water heater repairs in Singapore, there are a few common problems experienced by homeowners first-hand.

When it comes to water heater problems, we will classify them into storage heater problems and instant heater problems too. Oftentimes, these issues may be confused with misconceptions or myths, especially with Instant heaters.

Storage heater problems

  • Loss of energy

When heated water is stored for a short amount of time without being used, about 40% to 60% of the heat energy can be lost. This can happen when the owner does not use the heater after it is heated but chooses to use it after a while.

  • High operation cost

A storage heater takes up a high amount of energy to heat up the entire tank before use. It can be even higher to keep the water heated overnight for morning use.

  • Difficulties in temperature control

The storage heater may not provide the ideal temperature you want, which can be the case if the storage heater is improperly sized for your home.

  • Abrupt temperature fluctuation

This issue is more common in automatic storage heater tanks. With time, the heat sensor may dull causing the temperature to fluctuate, which will lead to the water not being heated to a satisfactory extent.

Instant heater problems

  • Initial cold outflow

The initial outflow from the water heater may not be heated as it takes some time for the water to be heated through the pathway, unlike the storage heater which provides consistent heated water due to pre-heating.

  • Abnormally heated water

If the temperature is set too high and the output valve is set in a way that allows only a limited amount of water to pass through, this may lead to water being heated to a very high temperature flowing out.

  • Noise

Noise could be heard if the water heater has been around for some time. Constant heating of the water will cause wear and tear, which could be a sign of a need for replacement.

  • Leaking

As mentioned above, as time flows by, the instant heater is more prone to experience leakage, which may be caused by pressure, corrosion, or even overheating of the instant heater. These are just some factors that may contribute to the leakage, there are also other causes of leakages that are often dealt with in another way.

  • Discoloured discharge

Water discolouration can occur when the heating rod within the water heater becomes corroded.

It is important to keep in mind that although the water heater may develop problems in its later years, we can still take precautions to ensure that the issues would not affect the safety of your household. If your household has kids, be sure to set the temperature to a lower amount so as to prevent any accidents. Always educate the children to ensure proper water heater usage.

Proper water heater maintenance

In order to avoid some of the issues mentioned above, it is vital to look out for key areas during the water heater installation. However, proper maintenance should not be overlooked as it can prolong a water heater’s life and deter any possible issues in the near future.

  • Anode rod

The anode rods are made of aluminum or magnesium surrounding a steel wire. It acts as a protective agent that prevents the water heater tank from rusting. The anode rods should be inspected on a regular basis. If it is discovered that it is rusting or the steel wire is exposed, then the anode rod is due for a change. Frequent usage of the water heater will hasten this process; thus, it is advised to have an inspection is done yearly or every half a year.

  • Dip tubes

Dip tubes are flexible piping that directs cold water into the water heater for it to be heated up. Not every water heater may have them as some may be directed by other types of tubes. It is also prone to corrosion along the way, so it is would be good to get a technician to conduct a check on the tube every 6 months.

  • Flush

It is recommended to flush the water heater every year so as to wash out any sedimentation that could be in the water heater. Flushing with disinfectant will also prevent bacteria that may be in the tank from developing and multiplying.

  • Draining

Draining is more related to storage heater tanks. The storage heater tank should be drained when there is a prolonged period of non-usage. This is to prevent any harmful bacteria from developing inside the tank, which may cause corrosion and health hazards.

  • Water inlet piping

These inlet piping are not exactly part of the water heater, but it is essential to supplying water to the water heater and should be inspected for any wear and tear, and leakage so that the water heater can function optimally without any hiccups.

  • Temperature & Pressure (TP) Valve

The Temperature and Pressure valve is found on a storage water heater. This valve is a mandatory valve required by legislation to be installed on the storage tank. Its main purpose is to protect the water heater from excess pressure and temperature by allowing it to discharge the excess when it begins to go over the limitations. If there are constant drippings from the TP valve, it may be loose and would need to be replaced.

  • Insulation

Proper insulation of the water heater or the piping can ensure that the heat transfer can be done smoothly through the water, and prevents the heat from escaping along the way. This will translate into prolonging the longevity of the water heater.

It is recommended to get a plumber to do an inspection of the water heater and do the necessary maintenance to prolong the water heater’s life span. Do note that the advisable period would be every 5 years or earlier.

Why would I need a water heater replacement or repair?

Common reasons for a water heater replacement are when it does not produce hot water when it trips the power when switched on when the heater is leaking or if the water from the heater is discoloured or has an odour.

What are the signs that your water heater is failing?

  • Rusty water – When rusty water appears, it is caused by rusting in your water heater or a rusty pipe.
  • Water surrounding heater – The metal in the heater tank expands when it heats up, allowing fracture and a tiny leakage to happen.
  • Rumbling sound – A sediment buildup happens at the bottom tank of the water heater over time and hardens each time it heats up, causing the banging or rumbling noise to emanate from the heater.
  • Burn marks – Burn marks on your water heater’s bottom could suggest two possible issues – improper venting and damaged flue pipes. These are huge signs that your water heater is failing and about time you get a replacement.

Should I repair or replace my water heater?

A water heater should be replaced if it faces a recurring problem, if the damage is too severe, or if the water heater is old enough.

What are the things to look out for during water heater installation?

  • Location – Whether a plaster or drywall, it is important to look out for the area where you want the water heater installed.
  • Water supply route – Water is supplied to the water heater, and either used immediately or stored depending on the water heater. Instant water heaters require you to route the pipes supplying water to it and ensure the instant hot water heater pipe leads straight to the inlet, while the water pipe supplying your home is attached to the outlet.
  • Ensure proper clearance – When installing storage water heaters, there should be a minimum of 15cm clearance on the perimeter of the water heater, and place it away from any flammable material.
  • Test it out – Do not start up the electricity lines, but only the water valves. Open the faucets in your home to get water running from the model for 1 – 2 minutes and shut the valves off. Get the inline filter off, and remove any debris you find. Test the appliance to ensure that it is properly functioning.
