When it comes to replacing or installing a water heater, many homeowners believe buying the unit from a big box store and hiring a plumber just for installation will save money. This assumption seems logical at first glance, but it often leads to higher costs and more hassle in the long run. There are three key reasons why choosing a professional plumbing service for both the water heater and installation is a smarter financial decision.

Lower Prices Through Plumbing Supply Houses
Professional plumbers have access to plumbing supply houses that offer water heaters at prices lower than retail stores. These supply houses sell directly to licensed professionals, cutting out the middleman and retail markup. This means the cost of the water heater itself is often less when purchased through a plumber.
For example, a typical water heater that retails for $1,000 at a big box store might cost a plumber $800 or less through their supply channels. This price difference alone can cover part of the installation cost or reduce the overall expense for the homeowner.
Additionally, plumbers often have relationships with suppliers that allow them to get discounts on bulk purchases or newer models, which are not always available to the general public. This access ensures customers receive better deals without sacrificing quality.
Better Quality Units Mean Fewer Problems
Water heaters sold through plumbing supply houses are usually commercial-grade or higher-quality models compared to the standard units found at big box stores. These units are built to last longer and perform more efficiently, which saves money on energy bills and reduces the chance of early failure.
Big box stores often stock entry-level models designed for mass-market appeal, which may not hold up well under heavy use or in homes with specific water conditions. Professional plumbers select units based on the home’s needs, ensuring the right size, capacity, and features.
Handling Failures Saves Time and Money
When a water heater purchased from a big box store fails, the homeowner faces extra steps and costs. The plumber must disconnect the faulty unit, transport it back to the store for a return or exchange, and then reinstall the replacement. Each of these steps adds labor charges and inconvenience.
In contrast, when Water Heater Boys install a water heater we sourced, we handle any failures directly. If the unit needs replacement, we only charge for the visit to swap out the old tank. This streamlined process saves you money on labor and reduces downtime without the hassle of store returns.
For example, a homeowner with a big box store unit might pay for two or three service calls just to get a replacement installed. With a professional-installed unit, we manage the warranty and replacement efficiently, often at a lower total cost.
Additional Benefits of Professional Installation
Beyond cost savings, professional installation ensures the water heater is set up correctly and safely. Plumbers follow local codes and manufacturer guidelines, reducing risks of leaks, poor performance, or safety hazards.
We also provide valuable advice on maintenance and operation, helping homeowners extend the life of their water heater. This guidance can prevent costly repairs and improve energy efficiency.
What Homeowners Should Consider
When deciding where to buy a water heater, consider the total cost of ownership, not just the sticker price. Factor in:
The price difference between retail and supply house units
The quality and longevity of the water heater
Labor costs for installation and potential future repairs
Convenience and warranty handling by the installer
Choosing Water Heater Boys for both the water heater and installation offers a better overall value. It reduces unexpected expenses and provides peace of mind knowing the job is done right.
Water heaters are essential home appliances that impact comfort and utility bills. Investing wisely upfront saves money and stress later.
