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

The cost to install a tankless system depends on your home’s infrastructure, such as venting requirements and the size of your gas meter. Because these units provide on-demand heat, the installation process is more technical than a standard water heater replacement. We provide a full assessment of your home to determine the final investment required for a seamless upgrade. 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?

Standard tank water heaters usually last between 10 to 15 years. Tankless water heaters, however, are designed for longevity and can often last 20 years or more with proper maintenance, making them a durable choice for homes in Ontario.

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

The cost to install a water heater in Ontario varies based on the unit type and installation complexity. Tankless water heater installations tend to have a higher upfront cost due to the technology and potential need for plumbing or venting modifications. We can provide a precise estimate.

What is the most efficient type of water heater?

Tankless water heaters are recognized as the most energy-efficient option. They heat water on demand, meaning energy isn't wasted keeping a large tank hot when it's not in use. This efficiency can lead to significant savings on your utility bills.

What are signs I need a new water heater?

Watch for signs like a reduced hot water supply, unusual noises from the unit, or leaks around the base. If your current water heater is aging (10-15 years) and showing these symptoms, it's a strong indicator that a replacement is needed in Ontario.

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

Sediment buildup is a frequent issue with tank water heaters, affecting performance and lifespan. Tankless units can sometimes experience problems with mineral deposits or vent blockages. Regular professional check-ups help prevent these common issues.

Is it worth it to repair a hot water heater?

Repairing a newer water heater for a minor problem is often a good investment. However, if your unit is old, has needed multiple repairs, or is an inefficient model, the long-term benefits and cost savings of installing a new, more efficient system, such as a tankless unit, usually make it the better choice.
