Rent or Buy a Water Heater in Cornwall?
When you own your water heater, you pay approximately $2,500 upfront for purchase and professional installation. After that, your cost doesn’t increase over time (excluding routine maintenance).
When you rent, the average cost is about $40 per month — which may seem affordable at first, but adds up significantly:
- 1 year: Approx.$480
- 10 years: Approx.$4,800
- 15 years: Approx.$7,200
Over the lifespan of a typical water heater, renting can cost two to three times more than buying. While renting a water heater saves you the initial upfront price, it significantly costs more over a prolonged perspective of thousands of dollars over the life of the unit
Also to Consider:
- Rental contracts can complicate home sales and even impact the value of your home.
- Many rental agreements allow some maintenance and repair. Ensure these benefits really offset the total rental cost.

Hot Water Tank Replacement Vs. Tankless Water Heater Installation
Traditional tank water heaters heat and store a set amount of hot water so it's ready when needed. Tankless water heaters heat water as it passes through the system, eliminating the need for a storage tank.

Frequently Asked Questions
Is it cheaper to purchase and install a new water heater myself?
- Purchasing a water heater and doing your own hot water tank installation may save you the up-front cost of hiring a professional installer, but it is not recommended for a variety of reasons.
- Attempting your own water heater installation can put yourself at risk for costly problems later. Whether it’s a hot water tank replacement or tankless water heater installation, the job requires specialized work with electricity, pressurized equipment, plumbing and gas lines, all of which can pose significant safety hazards if not done properly and in compliance with bylaws and building codes in Cornwall.
- Even transporting your new hot water tank must be done correctly to avoid damaging it. Our installers in Cornwall will ensure safe, careful transportation of your new equipment.
How long does it take to remove and install a new replacement water heater?
- On average, a simple hot water tank replacement can be completed in about 3 hours. In that time, your installer will be able to disconnect and remove your old tank, place and connect the new one, and test your new system to ensure it is working properly.
- Allow more time for new hot water tank installations or tankless water heater installations where additional changes to existing wiring, gas hookups and/or exhaust piping are required.
- We encourage you to speak with your installer to get a clearer sense of the time they will need to complete your water heater installation in Cornwall.
How will I know my service provider is authorized by The Home Depot?
All Home Depot water heater installers carry an orange Home Depot Home Services badge that features a picture and authorization number. If this badge is not visible, ask to see it. This badge means they have undergone a thorough background screening process and are properly licensed and insured in Cornwall.
Does The Home Depot install water heaters purchased separately?
No. The Home Depot’s water heater installers will not install water heaters purchased separately, whether from a Home Depot store or elsewhere. For liability and warranty coverage, they only install and verify equipment supplied by Home Depot.
Does The Home Depot replace rental water heaters from other water heater companies?
- Generally, yes. Our licensed water heater installers in Cornwall will source & install an energy-efficient new replacement water heater for your home, whether you own or are renting your existing system.
- Some water heater rental contracts contain penalties and other charges related to terminating your agreement, particularly if the unit is still relatively new. It’s crucial that you speak to your rental provider to understand your obligations before proceeding.
- We also encourage you to speak with our expert water heater installers in Cornwall about your rental agreement, as they may advise or assist you depending on your situation.
Do I need a permit for my water heater installation in Cornwall?
- Generally, a permit is not required for a hot water tank replacement in Cornwall. Depending on your location, a permit may be required for some new water heater installations.
- Permit requirements and pricing vary by province and municipality. Our water heater installers in Cornwall will inform you if a permit is needed and review the process and costs with you.
Which type of water heater should I install in Cornwall?
- Our licensed water heater installers in Cornwall are qualified to handle all types of water heater installation.
- Consider fuel source (gas or electric), storage capacity (up to 80 gallons), tank type (tank or tankless), and warranty options.
- Installation cost will also impact whether you choose a conventional tank or tankless system.
Do I have an option of what type of water heater I purchase?
- Your Home Depot installer can provide and recommend a full range of options for any size, gas or electric.
- For tankless installations, our installers in Cornwall will source the best system and provide a detailed quote.
How do I know when I should replace my water heater?
- Water heater is over 10–15 years old (15–20 for tankless)
- Not enough or inconsistent hot water
- Reliability issues
- Signs of corrosion (rust or sediment)
- Rising energy consumption
What’s the difference between gas and electric water heaters?
- Gas heaters usually cost less to operate but are less efficient and have a slightly higher initial cost.
- Electric heaters cost more to operate but are more efficient and have higher energy ratings.
What’s the difference between a conventional hot water tank and a tankless water heater?
- Conventional tank heats and stores water continuously, good for high usage, up to 80 gallons, can be installed in closet, basement, or garage. Replacement is usually straightforward and affordable.
- Tankless water heaters have lower operating costs, take less space, reduce energy use up to 30%, provide continuous hot water but higher upfront cost and may require new venting.
What are some additional water heater features to consider?
- Ask about efficiency ratings, first-hour delivery, recovery time, and automatic shutoff valves.
- Self-cleaning units reduce lime/sediment buildup, extend tank life, maintain efficiency.
- Recovery speed: time to heat a full tank; look for fast recovery if high water usage.
- Automatic shutoff valves prevent fires by stopping gas flow if sudden surge or ground movement occurs.
What is the best way to ensure a longer life for my water heater?
- Flush your water heater annually to remove sediment or rust. This significantly increases lifespan and may exceed warranty period.
- Investing in a central water softener or filtration system optimizes performance and prevents scale/sediment build-up, extending water heater life.
