Unlicensed vs Licensed Storage Water Heater Installation in Singapore

When it comes to storage water heater installation in Singapore, homeowners are frequently confronted with a significant choice – deciding between an unlicensed installation or engaging a licensed professional storage water heater installation service with PUB submission. This article aims to shed light on the importance of licensed storage water heater installation in Singapore, highlighting the various factors that differentiate it from unlicensed installations. From regulatory requirements to safety hazards, warranty issues to installation costs, this comprehensive guide will provide homeowners with the necessary information to make an informed decision.


PUB Regulation


The Public Utilities Board (PUB) in Singapore plays a vital role in ensuring the safety and quality of water supply. In line with their regulations, all storage water heater installations must be carried out by licensed plumbers. One reason why you should hire a professional to install your storage water heaters is to ensure that the installation meets the necessary safety standards and does not pose any risks to the homeowner or the general public. Engaging a licensed plumber ensures compliance with PUB regulations, giving homeowners peace of mind knowing that their storage water heater is installed correctly.


Warranty Issues

Warranty is a significant consideration when installing a storage water heater. Most reputable manufacturers provide warranties that cover the product and its installation. However, these warranties are often voided if the installation is not carried out by a licensed professional. 

Opting for an unlicensed installation can result in a loss of warranty, leaving homeowners responsible for any repairs or replacements when encountering issues with storage water heaters. By engaging a licensed plumber for storage water heater installation, homeowners can ensure the warranty remains valid, providing them with the necessary protection and peace of mind.


Safety Hazards

Perhaps the most critical factor to consider when choosing between licensed and unlicensed storage water heater installation is safety. Licensed plumbers undergo extensive training and adhere to strict safety protocols, minimizing the risk of accidents or hazards. 

On the other hand, a reason you shouldn’t hire an unlicensed storage water heat installation service is that they often lack the necessary expertise and safety measures, posing a significant risk to homeowners and their property. From gas leakages to electrical fires, improper installations can have severe consequences. By engaging a licensed professional, homeowners prioritise safety and protect themselves and their loved ones from potential hazards.


Improperly Secured Wires

Another common issue with unlicensed storage water heater installations is the improper securing of wires. One thing you should know about when hiring licensed storage water installation service is that they possess the expertise to manage electrical connections securely, guaranteeing that wires are fastened correctly and won’t meld together. This is vital in avoiding electrical malfunctions, short circuits, or potential electrical fires.

On the other hand, unlicensed installations often involve haphazard wiring, increasing the risk of electrical hazards. By engaging a licensed professional, homeowners can rest assured that the wires are correctly secured, minimizing the chances of any electrical mishaps.


Use of Quality Parts


One of the key benefits of hiring a licensed professional for storage water heater installation is the use of quality parts. Licensed plumbers are well-versed in the industry and have access to reliable suppliers who provide genuine and durable parts. 

On the other hand, unlicensed installations often involve the use of substandard or counterfeit parts, which can lead to frequent breakdowns and costly repairs. By opting for a licensed installation, homeowners can be assured that their storage water heater is equipped with high-quality parts, ensuring its longevity and efficient performance.


Installation Costs


While some homeowners may be tempted to opt for unlicensed installations due to lower costs, it is essential to consider the long-term implications. PUB-licensed plumbers may charge higher upfront fees, but their expertise and use of quality parts result in a more reliable and durable storage water heater installation

Unlicensed installations, on the other hand, may save money in the short term, but homeowners often end up spending more on frequent repairs and replacements. Therefore, it is advisable to double-check the plumber’s servicing cost before making a decision, as investing in a licensed installation can lead to significant cost savings in the long run.


Positioning of Storage Water Heater


What you should know about storage water heaters is that proper positioning is crucial for its efficient operation and safety. Licensed plumbers have the necessary expertise to determine the optimal location for the water heater, taking into account factors such as ventilation, accessibility, and proximity to electrical outlets. 

Improper positioning can lead to various issues, such as inadequate heating, overheating, or even fire hazards. It is essential to engage a licensed professional who understands the intricacies of storage water heater installation and ensures that it is positioned correctly to guarantee optimum performance and safety.
