What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

Replacing a water heater involves removing the old tank, disposing of it, and installing a new unit that meets current safety standards. Price factors include the size of the tank, the type of fuel used, and any necessary updates to your existing pipes. We help you choose a replacement that balances your hot water needs with your budget. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in Ontario

How long do hot water heaters typically last?

In the Inland Empire, water heaters generally last between 8 to 12 years. Factors like the mineral content in the local water and how frequently you use hot water can influence this lifespan. Regular maintenance, such as flushing the tank to remove sediment, can help prolong its life. The pros can assess your unit's age and condition.

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

For efficiency in Ontario homes, consider high-efficiency tank models or tankless water heaters. Tankless units heat water on demand, saving energy by not constantly heating a large volume of water. High-efficiency tank models offer better insulation and performance. The pros can help you determine which type best suits your household's usage and budget.

What are signs I need a new water heater?

Signs you might need a new water heater include a noticeable decrease in hot water supply, rusty or discolored water from your faucets, and unusual noises like popping or rumbling. Leaks from the tank itself are a strong indicator that it's time for a replacement. If your unit is older, these symptoms warrant professional attention.

What is the most common problem with a hot water heater?

Sediment buildup at the bottom of the tank is a frequent issue, reducing efficiency and causing noise. Another common problem involves the thermostat or heating elements malfunctioning, leading to no hot water or insufficient hot water. While flushing can help with sediment, other issues often require expert diagnosis and repair.

Is it worth it to repair a water heater?

Repairing a water heater can be a good option for newer units with minor issues, such as a faulty thermostat or a small leak. However, if your water heater is nearing the end of its lifespan and has significant problems like tank corrosion or frequent breakdowns, replacement is often more economical in the long run. The pros can provide an expert opinion.
