Installing an instant water heater offers many benefits. Nonetheless, before engaging in water heater services, it is important to know some of the factors that suggest if your space is suitable for installing and replacing a water heater.

Some of the most crucial factors you must consider before installing an instant water heater are the hot water usage pattern, demand, budget, consumption, and current water heater at your place.


Power Consumption

Instant water heaters are smaller than storage water heaters, but they still provide heated water and are energy efficient. Without the storage tank, an instant water heater still provides hot water whenever you open the faucet or shower – making a convenient bathroom fixture and your home 23% more energy efficient. If you want to save more, install energy-efficient water heaters. Energy efficiency is one of the features to have in a brand new water heater.

Storage water heaters only have a limited capacity to store heated water from 151 to 227 litres. When installing or replacing an instant water heater, you will never have to worry about heated water consumption and supply. Instant water heaters provide unlimited heated water to an entire home’s faucet, showers, and more!


Hot Water Usage


Besides the price, selecting between instant and storage water heaters also depends on your water usage. For example, you should know where you will use heated water and measure your hot water usage. You can install instant water heaters to supply hot water to your water fixtures like faucets and showers. Likewise, you can set up each tap to receive hot water, depending on the time.

Instant water heaters available in the market today supplies heated water from 7.5 to 18 litres per minute. Your high-flow showerhead can provide a 7.5 to 9.4 litres per minute flow rate, while a washing machine consumes 11 litres per minute. Using hot water for laundry, dishes, and bathrooms is just some of the reasons why you should opt for an instant water heater installation. You can efficiently distribute hot water throughout your home as needed.


Overall Budget


Properly installing water heaters can be challenging with the electrical wiring and plumbing works. Hence, hiring a professional to install your storage water heater or instant water heater is the best decision. You may want to install a storage water heater based on service cost rather than an instant water heater. You only need around $300-$600 for the storage type, while instant water heaters require about $700. However, the long-term benefits of instant water heaters outweigh the low installation cost of storage water heaters.

One of the common misconceptions about instant water heaters is they can be costly to maintain and use. Instant water heaters are energy-efficient, and you only use them as needed. Also, storage water heater services for water heater leak repair and usage could be costly.


Current water heater

Setting up a new water heater requires the help of plumbers, electricians, and other contractors. The cost increases depending on the services needed. Thus, list the things to note during water heater installation – such as the location, water supply, and more. When you ask for a quote, always check the details to avoid water heater issues and potential extra fees during the installation.




Property owners always try to reduce energy consumption and their monthly utility bills. They can do so by installing an instant water heater in their homes. If you live in a small home, a storage water heater may not fit your bathroom. These are just some of the benefits and differences between a storage water heater and an instant water heater.

Lately, the types of instant water heaters available in the market feature advanced functions and parts, and plumbers may find them complicated to install. Instant water heaters seem like the best option for your home but installing one depends on your property or building. You need gas connections to heat water. Should you have your water heater replaced with an instant one, you need a gas connection. If you do not have the piping installation, instant water heaters may not be the best option for you despite the promising long-term benefits.



Instant water heaters have become most Singaporean homeowners’ first choice for the benefits it brings to the whole family. Most popular water heater brands offer instant water heater models packed with modern features. Nonetheless, before buying one for your space, know your preferred energy consumption, water usage, water heater set up, and your property. These factors affect your purchase and installation budget.
