A Step-by-Step Approach to Choosing Your Next Water Heater

| Monday October 2, 2023

Water heaters have significantly changed warm water production, giving home and business owners in the Philippines an efficient tool to provide an instant supply of hot water. But despite its importance to many properties in the country, water heating units are just appliances. They will eventually reach a point where they need to be replaced, whether because of old age or irreparable damage.


And it might look like an easy task for many, but water heater replacements can be tedious. The demand for warm water can change over time, and buying a similar unit like the old one might not be able to provide the necessary amount of hot water. In addition, only considering the shower heater price in the Philippines might lead to purchasing substandard heaters that can result in more expenses in the long run.


A systematic approach when replacing water heaters can go a long way regarding reliability and functionality. This can ensure you make informed decisions when choosing a new water heater, ensuring that the replacement unit meets their immediate needs. This can also guarantee long-term efficiency, cost-savings, and reliability, which can help water heater owners save money over time.


So, if you need to replace your current water heater anytime soon, here are some steps you can take that can help you purchase the water heater of your dreams.


Evaluate the Current Heater


One of the most important things to do before buying a new heater is to assess the condition and specifications of the current heating unit. This is vital as checking the condition of the existing water heater can provide critical information about the current plumbing setup and the hot water needs of the residents.


Various things can be checked in an old water heater, giving the necessary information when buying a new one. For starters, finding out whether the heater is powered by electricity or gas can assist in determining the existing infrastructure for the heater. In addition, the heater’s age should also be evaluated, as it is one of the main reasons replacement units are needed. The Energy Factor rating can also be examined as it can be compared with newer models.


Apart from this, assessing the current heater can help discover potential unnoticed flaws, including possible internal leaks, corrosion, and inefficient heating. This can help you decide which unit to purchase to avoid having the same issues as the old one.


Understand the Property’s Hot Water Needs 


Another critical step when replacing an old water heater is to understand the warm water needs in the property clearly. Water heaters are used for many activities, from showering, dishwashing, laundry, and cleaning. And if the heater is only used for the bathroom, the number of people in the property affects how much warm water is consumed daily.


Knowing the precise demand for hot water in the property can be invaluable in picking the right water heater size and capacity that caters to the needs of the tenants. A general rule of thumb for those who only use heaters for showering is that an estimated 10 liters of warm water is consumed per person/shower.


Learn About the Different Types of Water Heaters


There are several types of water heaters available in the market, and learning about them can be beneficial when deciding on your next heater. The warm water needs in the property constantly change, and comprehending the differences between the water heater types can enable you to make an informed decision before finalizing your purchase. This is also crucial as your pick can impact the property’s infrastructure, which means there might be a need to modify plumbing and electrical systems.


Many homeowners’ two most common choices are storage heaters and tankless instant water heaters. Storage heating units allow properties to have a specific amount of warm water in the tanks, providing instant access to hot water for various activities. Meanwhile, tankless heaters provide an on-demand supply of warm water as they only heat water that passes through the unit, resulting in optimal energy efficiency.


Consider Your Budget and Space Requirements


Once you already know the warm water demands and water heater type you are looking to buy, it is crucial to look at your budget and space requirements. These are probably two of the most essential things to consider when buying a replacement heating unit, allowing you to purchase a heater that would not break the bank.


The budget for the new water heater is paramount as initial and installation costs can be pretty high. Brands offer many water heating units at different prices, so having a clear image of your budget can help you compare different products efficiently. Meanwhile, the available space in the property can also help you find heaters that fit where you plan to put the unit. This can help prevent you from spending more on modifications to fit the heater you purchased.


Work with Professionals


One of the most common mistakes people make when replacing their old heaters is to do everything on their own. Buying and installing water heaters involves dealing with complex systems, including electrical and plumbing connections, that usually require professional expertise. Working on it on your own can result in various safety hazards, including leaks, water damage, and electrical shocks.


Working with a plumber can be a game changer when replacing old water heaters. They can help with every step of water heater replacement, ensuring that you have a trusted expert who can guide you along the way. They can suggest water heating units to replace your old ones and have them installed efficiently on your property.




As modern heaters become more innovative, replacing old heating units is paramount for many residential and commercial properties. If you are already planning to purchase new heaters, it is vital to have a systematic approach to buying a new unit, as it allows you to make an intelligent decision. This guarantees that you can invest in a heater that caters to your needs and provides optimal functionality and efficiency.
