When to Replace Your Water Heater

Knowing when it’s time for a water heater replacement in Mississauga can save you from costly repairs or property damage. Here’s what to watch out for:

plumbing

Rusty or Discoloured Water

Brown or reddish water coming from your taps is a common sign that the inside of your tank is corroding. Left unresolved, this can lead to leaks and ultimately result in the complete failure of the tank. It may also indicate deterioration in your home's plumbing system; however, the culprit is often an aging water heater.

Lack of Hot Water

Suppose you're constantly running out of hot water or experiencing fluctuating temperatures. In that case, it may mean your heater can't keep up anymore—or that it's losing efficiency. This is particularly inconvenient during morning routines or when multiple people in the household rely on hot water for their daily needs.

Frequent Repairs

Needing constant service calls? That's a red flag. Components like the thermostat, heating element, or pressure relief valve may be deteriorating. Replacing a failing unit is often more cost-effective than continuing to fix it.

Unit Over 10 Years Old

Most traditional tank water heaters last around 8–12 years. If yours is a decade old, replacement is often the smarter, safer option. Newer models are far more efficient and built to stricter safety standards.

Tank Leaks or Noise

Leaks require immediate action, while banging or rumbling noises may indicate sediment buildup—a sign of a struggling unit. Ignoring these sounds could lead to internal damage, flooding, and property damage.

Our Recent Projects

Replacement Options Available

At Delex Plumbing, we provide a range of replacement options to suit every budget, home size, and energy preference.
1

Standard Tank Models

Traditional tank water heaters are affordable and familiar. They are ideal for homes with steady hot water usage and space for a large tank. These units store a set amount of water and continuously heat it, ensuring hot water is always available.
2

Tankless Units

Want hot water on demand? Tankless water heaters heat water only when needed—perfect for energy savings and space-conscious homes. These systems are more compact and often have a longer lifespan than tank models.
3

Energy-Efficient Upgrades

Today’s models include ENERGY STAR-certified units that can significantly reduce your energy consumption. High-efficiency units utilize advanced technology to minimize standby heat loss and enhance performance. Over time, these savings can offset the cost of the upgrade itself.
4

Electric vs. Gas Systems

Electric units are easy to install and maintain, while gas systems offer faster heating and lower operating costs. Your choice depends on existing infrastructure and usage habits. We’ll help you compare upfront costs, energy efficiency, and long-term performance.
5

Sizing Recommendations

From compact 30-gallon units to 80-gallon tanks and high-flow tankless models, we match your water heater size to your household’s daily hot water demand. Proper sizing ensures efficiency and prevents future issues with performance or capacity.
