Key Features to Look for in an Instant Water Heater

When shopping for an instant heater, specific features can significantly enhance its performance and durability.

Instant Hot Water

FUJIOH instant heaters provide hot water shortly after you turn on the shower tap, without extended waiting.

Adjustable Temperature

You can adjust the temperature of the shower water to your desired comfort level by simply turning the control knob.

Water Filtration

These water heaters include a stop valve with a built-in filter. This filter helps to prevent dirt and other particles from entering the unit, which is important for protecting the internal flow switch.

Environmental Friendliness

Instant water heaters are environmentally friendly as they consume less energy and reduce water wastage. By heating water on demand, they lower your home’s carbon footprint while helping you save on utility bills. Many modern models also use eco-friendly materials and manufacturing processes, further contributing to sustainability.

Instant Water Heater Safety Features You Should Know

Safety is paramount when it comes to water heaters. The following safety features ensure your heater is both secure and reliable for daily use.

Overheat Protection

Overheat protection is a critical safety feature that ensures the water heater doesn’t exceed a safe temperature. This prevents potential damage to the unit and protects users from scalding. It also enhances the overall lifespan of the instant heater by preventing unnecessary wear and tear.

Dry Heating Protection

Dry heating occurs when the instant heating element operates without water, which can damage the unit. Dry heating protection safeguards the instant heater by automatically shutting off the element when no water is detected. This feature ensures the safety and longevity of your appliance.

Pressure Relief Valve

A pressure relief valve is essential for releasing excess pressure that can build up inside the unit during operation. This not only prevents potential damage but also ensures safe use, especially in high-pressure water systems.

Temperature Control and Regulation

Temperature control allows users to set and maintain their desired water temperature, providing a safe and comfortable experience. Some of the most modern instant water heater models also include automatic regulation systems to prevent overheating and ensure consistent performance.

Leak Detection

Many instant water heaters come with built-in leak detection systems to identify and address leaks promptly. This feature helps prevent water damage, reduce waste, and maintain the heater’s efficiency over time.

Electrical Surge Protection

Electrical surge protection safeguards the instant water heater against power fluctuations, preventing potential damage to its internal components. This feature ensures uninterrupted performance and enhances the unit’s durability.

Maintenance Tips for Your Instant Water Heater

Proper maintenance is also essential for keeping your heater in top condition.

Clean the Water Filter Regularly

To ensure consistent shower performance, periodic cleaning of the water filter is recommended. This involves removing the filter head from the stop valve, taking out the filter net, and gently cleaning it with a soft brush under running water. Make sure all trapped dirt particles are thoroughly removed before fitting the clean filter back into the stop valve.

Inspect for Leaks

Conduct routine checks for leaks in the unit or connections to prevent water wastage and damage to surrounding areas. Promptly addressing leaks also enhances the safety and longevity of your instant water heater.

Seek Professional Help

For certain malfunctions such as electrical issues or a faulty triac, it is important not to attempt repairs yourself. Instead, have the shower unit thoroughly checked by a qualified and competent electrician or contact our dedicated Customer Service for assistance. Similarly, if you suspect a flow switch malfunction, professional diagnosis and repair are necessary to ensure the safe and proper operation of your water heater.

Ensure Proper Water Pressure

Maintaining appropriate water pressure is essential for the efficient operation of your instant water heater. Excessive pressure can strain the unit, while low pressure may lead to inconsistent heating.

Clean the Exterior

When cleaning the exterior of your water heater, avoid using thinner, alcohol, or petrol. Many household cleaners contain abrasive chemicals that can damage plated or plastic fittings. Instead, gently clean these surfaces with a mild washing-up detergent or a soap solution. After cleaning, wipe the exterior thoroughly dry with a soft cloth to maintain its finish.

Test the Temperature Control

Regularly test the temperature control to ensure it’s functioning correctly. This helps you avoid unexpected fluctuations and ensures safe usage.

Frequently Asked Questions About Instant Water Heaters

1. Are electric instant hot water heaters worth it?

Instant hot water heaters can be totally worth it, however, it depends on your specific needs and circumstances. The main advantage of instant electric water heaters is you can have instant hot water as and when you need it.

2. How effective is an instant water heater?

An instant water heater is an effective solution for providing a hot water supply on demand and instantly without having to wait. If you do not want to heat and store large volumes of hot water, which is possible through our storage water heaters, you can try our instant water heaters instead. They only heat the amount of water that is used at any given point in time. This makes them useful for busy households or in instances where a quick source of hot water might be required, such as the early morning rush to get ready for work or school.

3. Is an instant water heater or a storage tank better for homes in Singapore?

Choosing the better option really depends on your priorities. An instant heater is ideal for HDB and BTOs as it saves significant space and conserves energy by heating water only on demand. However, a storage heater may be suitable if you prioritise stronger water pressure, though it requires more space.

5. What water heaters are new BTO homeowners using?

While the final choice depends on homeowner needs, new BTO owners often use water heaters with features, such as precise temperature control, temperature stability, and energy efficiency.
