Truth Unveiled! 5 Common Water Heater Myths Debunked

Debunking water heater myths

In the realm of home appliances, few are as essential and taken for granted as the humble water heater. It's the unsung hero that brings warmth to our showers and makes dishwashing a more tolerable task. 

Yet, amidst the convenience they provide, water heaters often find themselves shrouded in myths and misconceptions. Let's embark on a journey to debunk five prevalent myths surrounding water heaters and uncover the facts that may reshape the way you perceive these everyday appliances.

Myth 1: Storage heaters cannot produce hot water instantly

One common misconception is that storage water heaters fail to deliver instant hot water. The truth is, these heaters are designed to store hot water in a tank, maintaining its temperature for up to 24 hours.

This ensures a readily available supply, ready to be tapped into on demand. The myth of delayed hot water is nothing more than a misunderstanding of the storage heater's efficient design.

You can and should be able to get hot water instantly with a storage water heater.

Myth 2: Storage heaters consume electricity if left on for over two hours

Another prevalent myth revolves around the notion that leaving a storage water heater on for an extended period leads to unnecessary energy consumption.

In reality, well-insulated storage heaters activate their thermostat only when the water temperature drops by approximately 5 degrees. The 12-hour cycle to register this minimal drop showcases the efficiency of a properly insulated heater.

Researching and investing in a well-insulated heater can significantly contribute to energy savings, debunking the myth of rampant electricity wastage.

Myth 3: Water heaters should not be switched off after use

Contrary to the belief that constantly turning a water heater on and off accelerates wear and tear, the truth is quite the opposite.

Water heaters should be powered off when not in use, and the on-off cycle doesn't harm the internal mechanisms of the heater. There's no complex reboot system in play; it is just a straightforward cut in and cut out of power to the thermostat.

Knowing when to switch off your water heater can save you lots of money in the long run.

Myth 4: Turning off the water heater means no more hot showers.. immediately!

Contrary to popular belief, you might think that powering off your water heater equals an immediate plunge into icy showers. However, the reality is quite the opposite.

Even when your water heater is switched off, the storage tank acts as a reserve of hot water. The heating element might be inactive, but you can still enjoy hot water till the tank runs out, dispelling the myth that a powered-off heater spells the end of your hot shower bliss.

Myth 5: Higher wattage equals higher energy consumption

A common misconception suggests that a higher wattage water heater translates to increased energy consumption. However, wattage alone doesn't determine energy usage.

Consumption depends on usage patterns. Families of different sizes may use a water heater with the same wattage, but the key factor to how much energy they consume is how much hot water is used.

Higher wattage simply means faster heating, not necessarily more energy usage. Understanding this fact can help you make an informed decision based on your household's specific needs.

Conclusion

Understanding the truth behind these water heater myths can empower you to make informed decisions about your appliances. It also helps you to use your water heater intelligently.

By debunking these myths, we pave the way for a more efficient, cost-effective, and sustainable approach to water heating. Now, you're better equipped to save energy for your home! 

Aircon Ledge Installation: Can you do it in Singapore?

For HDB, its a no! Condos, maybe.

HDB regulations generally prohibit installing heaters, including water heaters, on the aircon ledge, though some condos allow it.

HDB flats typically require water heaters to be installed within the unit, such as in the service yard or bathroom. If you're a resident, you should verify specific regulations with your contractor or the HDB directly to avoid non-compliance.

If in doubt:
• Contact Town Council or MCST directly
• Consider indoor placement, the safe option

Worst case:
• You may be asked to dismantle heater at your own cost

Why this rule exists:

Safety:
• HDB regulations are in place to ensure the safety of the building and its residents.
• This means preventing installations that could be hazardous
• These installations may block essential building functions

Compliance:
• Improper installation can lead to issues with the building's structure
• Some walls are not meant to be drilled
• For condos, aesthetics are important as well as potential fire or gas leak hazards.
Installation Team did an outstanding job in the installation of my storage heater. Patient and very tidy. Did not tarnish the looks of my condo unit at all. Really appreciative of them as I was initially hesitant to swap out my gas heater for fear of having unsightly pipes and trunking due to wiring and piping. Absolute joy and pleasure. I am glad i made the switch. Thank you once again AOSbath.

When my instant gas water heater stopped working, I started looking around for an electric storage heater. After much research, I decided on AOSmith from AOS bath. Highly recommended.

The AOSmith was a much needed upgrade. Hot water was always available rather fast and water temperature remain relatively stable. Very very good experience! Installation was a breeze thanks to Suruj and Rana.

Aircon ledge FAQ

What is the best place to install the heater?
All heaters has a dedicated location. Some are above false ceilings, some are meant to be installed inside bathrooms.

There should also be a dedicated power source and suitable mounting wall close by. Shifting your heater away from the dedicated location may require you to shift water pipes and electrical points.
About 10% of heaters installed in Singapore are at air-con ledges. Most of these are gas heaters in condominiums. These heaters have already been pre-installed by developers when the condo was built.
You will need to do lots of piping and electrical work. It is best to do this only when your house is under full renovation.

It is also important to check your ceiling height space to ensure there is enough space to fit a heater tank. If your condo was originally fitted with a gas heater, the ceiling height space may be shorter than others.
