How Much Is a Hot Water Tank Rental in Ontario?

For many homeowners, buying a new hot water tank means a larger upfront expense, while renting a hot water tank spreads the cost into affordable monthly payments. Rental agreements may also include routine maintenance and repair services. That said, deciding between buying and renting comes down to a lot more than initial costs alone.

This guide outlines how much hot water tank rentals are across the Greater Toronto Area, what's included in agreements, how to determine which option is right for you, answers to frequently asked questions, and more.

Buying your hot water heater outright may cost less over time, but does require a greater upfront investment. On the other hand, renting often requires a lower upfront cost and may include maintenance and repairs in each monthly payment. The right choice for your household will depend on the type of equipment purchased, the terms and conditions of the agreement, and how long you anticipate remaining in your home.

There isn't a single rental price across Ontario. Monthly rental fees will vary between providers, tank size, equipment type, location, and the rental agreement itself.

Current public examples for 2026 across Ontario include:

Note that some rental companies may also charge application, water heater installation, and other fees that are subject to HST.

Buying a water heater costs more upfront than rentals. However, once the purchase price is paid, you gain full ownership of the equipment and do not have to make ongoing payments toward ownership.

The cost of a new water heater can range between $1,200 and $2,800 for a tank model, while tankless water heater replacement costs can range between $3,500 and $6,500 or more.

Furthermore, an installation quote may include the following costs:

• The equipment

• Labour costs

• Delivery

• Removal and disposal of old equipment

• Plumbing, venting, gas, and electrical materials

• Testing the unit

• Warranty coverage

• Applicable taxes

A monthly rental fee can appear cost-effective when viewed by itself, but over time, that monthly payment will add up. For example, a monthly payment of $24.76 will look like the following over time:

• One year: $297.12

• Five years: $1,485.60

• 10 years: $2,971.20

Rates over time may also increase, which means you could be paying more every year.

The best way to compare buying vs. renting is to look at the total expected costs over how long you will be using your water heater.

Estimated buying cost = Installation + equipment cost + maintenance + repairs not under warranty + tax/ownership length

Estimated rental cost = Monthly rental fee + rate increase + additional fees + maintenance and repairs not included + taxes + cancellation or buyout costs (if applicable)

Rental agreements will vary between providers. Sometimes, they'll include the equipment, installation, regular maintenance, parts, labour, and repairs. Others may only include the equipment.

Ask exactly what “included repairs” means

When comparing rental agreements and companies, check whether "included repairs" cover:

• Parts

• Labour

• Service-call fees

• After-hours service

• Replacement equipment

• Damage unrelated to normal wear

• Venting

• Code upgrades

• Water damage

When you own a water heater outright, your main costs will be paid in the beginning. Afterwards, costs can include maintenance, repairs, and replacement costs in the future.

Yes, depending on the fine print of your contract, you may be subject to a rental rate increase each year. That's why you'll want to confirm the following:

• Whether your current rental price is guaranteed over the course of your rental term.

• How rental increases are determined.

• How much notice is provided

• Whether or not there is a maximum increase amount

Knowing this information ahead of time is essential, as it can significantly change what you pay in the end.

Again, how cancellations and buyouts are handled will depend on your agreement. Before you sign your contract, check whether it includes the following:

• A minimum rental term

• Early cancellation charges

• Buyout options

• How the buyout amount changes over time

• Whether removal costs are included or additional

• Your responsibilities for returning the equipment

Water heater rentals and lease-to-own agreements are not the same. Traditionally, rental agreements keep ownership in the hands of the rental company. On the other hand, lease-to-own programs provide homeowners with a path to ownership.

For example, Enbridge Sustain offers lease-to-own options with 15-year terms. You pay a monthly fee, and by the end of your agreement, you'll own your water heater outright. Early buyout options are also available, and maintenance and repairs are included in your monthly payments.

Below is a further outline of the differences between renting, lease-to-own, and buying:

The same considerations will apply to tankless systems as they do to conventional tank models. That said, upfront costs and rental payments will likely be even higher. Published examples across industry professionals reveal monthly payments of $52.26. With 120 unchanged monthly payments, the total costs would be $6,271.20 before HST.

To put this number into perspective, on average, the cost of a tankless water heater in Ontario in 2026 ranges between $3,500 and $6,500 or more. This comparison alone doesn't mean that buying is cheaper. Rates can change, and what's included in the rental agreement also matters.

To help you decide which option is right for your home, here's an easy-to-follow checklist:

Lease-to-own options may be worth considering for homeowners in Ontario who want lower upfront costs, affordable monthly payments, and a clear pathway to ownership in the end.

Before signing a rental agreement, ask the rental company the following questions:

1. What is the monthly payment today?

2. Does the monthly rate increase?

3. What is the initial contract term?

4. What is included in the installation services?

5. Which repairs and maintenance are included, if any?

6. What is specifically excluded from the rental agreement?

7. Can I terminate the agreement early?

8. What does the buyout cost today, and how does it change?

9. What happens if I sell my home?

10. What will I have paid after 5 and 10 years?

Note that under Ontario's Consumer Protection Act, those who sell water heaters must follow disclosure requirements, including providing itemized invoices for all services and other charges, payment terms, total lease payments over the period, and other information to customers.

Ontario homeowners who can comfortably afford the initial cost of buying a new water heater and ongoing costs may consider paying for their equipment upfront, as the cumulative costs over time are often lower than renting equipment. Rental services, on the other hand, may be the better option for homeowners who prefer lower upfront costs and all-in-one services for maintenance and repairs.

Remember to compare costs in the long run, ask whether rate changes apply, and what happens at the end of your rental agreement in terms of ownership.
