Certainly, you will not be able to do a task that requires a water heater if you do not have a water heater installed. A water heater’s performance may decrease over time due to overuse.

However, you can prolong the lifespan of your water heater and make it serve you for a longer time. For this to be possible, you first need to be aware of the factors that can affect the lifespan of your instant water heater, which are in detail below.


Build Quality

Choosing a low-quality instant water heater cannot guarantee that it will last you for a long time. Just like other home appliances, the higher the price is of the water heater, the better the quality will be. If you engage water heater professionals such as Water Heater City Singapore, we can help you find the best instant water heater in Singapore which meets your demands and is affordable. Our experts have excellent knowledge of the different water heaters available in Singapore. Not only will we help in finding the ideal instant water heater for you, but we will also help to install the water heater at your home.


Water Pressure

High water pressure is bad for your instant water heater. It can cause system damage to the unit and decrease its working lifespan as well as make your water heater faulty. If you already have a pressure relief valve (PRV) installed, this will help to remove any excess pressure to prevent your water heater from experiencing any issues.




Proper water heater installation also has a vital role to play. No matter how expensive or how good a brand your heater is, if it is not installed the right way, common water heater problems may occur. You should hire a professional technician to help you decide if you are going to install either an instant water heater or a storage water heater. Factors like ventilation, insulation, accessibility, and the building codes are to be considered.




The lifespan of your instant heater depends a lot on the way you use it. Huge amounts of water will increase the workload on your instant heater – one of the reasons that your water heater may be failing as it is overworking to meet your demands.

Selecting the right size of the water heater is very important. If you now have an upper story or have perhaps added a few rooms, then you should choose an integrated instant water heater like Rheem RTLE – 33P. You should replace the old water heater that does not meet the household demands.




If you want your instant water heater to last you for a very long time, it is necessary to opt for regular maintenance. You will need to engage a water heater professional to schedule regular maintenance for your water heater. The water heater professional is well trained and has years of experience in dealing with all types of water heater issues. As part of their maintenance process, they will flush your tank on a regular basis. This will help remove the sediment from the bottom of the heater tank and keep it clean. They will also inspect the entire water heater and see if there are any problems. Corrosion, water present under the base of the unit, and rust stains are some signs that you might need to replace your water heater.



Newly bought instant water heaters from top best-selling water heater brands can prolong their lifespan if they are correctly maintained. Considering factors (e.g., overtime usage of the water heater, the water pressure of the water heater, and the build quality of the instant water heater) that affect your water heater lifespan can help you assess if you should replace or repair your water heater. If you are looking for a long-lasting instant water heater, do consult a water heater professional such as Water Heater City Singapore so that they can recommend instant water heaters that meet your demands and provide installation services.
