What affects the price

Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.

About this service

Electric tankless units provide hot water by heating it as it passes through high-powered electric coils. These systems require a specific electrical service capacity to function correctly. If your unit isn't heating properly, the issue often lies with the flow sensor or a tripped breaker. We can help you troubleshoot these units or install a new system if your current one is failing. Installation costs typically depend on your home's electrical panel capacity, with exact pricing confirmed free on the call.

Frequently asked in Ontario

How long do hot water heaters typically last?

Most tank-style water heaters last about 8-12 years. Electric tankless models, with proper care, can often last 20 years or more. The pros in Ontario can give you a more precise estimate based on the unit and your household's usage patterns.

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

What is the most efficient type of water heater?

Electric tankless water heaters are often considered very efficient because they heat water only when you need it, which can save energy in Ontario homes. However, the 'most efficient' choice can also depend on your specific hot water usage. The specialists can help you find the best fit.

What are signs I need a new water heater?

Look for signs like rust-colored water, visible leaks, or unusual noises coming from your current unit. If you're frequently running out of hot water in Ontario, it's a strong indicator that it's time for a replacement. Addressing it early prevents bigger issues.

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

Sediment buildup is a frequent issue for tank water heaters, which can cause noise and reduce efficiency. Electric tankless units might experience problems with heating elements or flow sensors. The local pros are skilled at diagnosing and resolving these common issues quickly.

Is it worth it to repair a water heater?

Repairing a water heater can be worthwhile if the unit is relatively new and the repair cost is reasonable compared to a replacement. If your water heater is older or requires extensive repairs, investing in a new, more efficient model might be a better long-term decision for your Ontario home.
