Buying a New Water Heater in Ottawa

There are many options for water heaters on the market today from the classic, reliable storage water tanks to the modern, compact tankless water heaters. Some homes even use what’s called a combi boiler to provide both heating and hot water to the home. We outline all these options below to help you select the right equipment for your home and your family.

Types of Water Heaters

A water heater provides your home with hot water by burning fuel like natural gas or propane or by using electricity. This hot water is then distributed throughout the home through your plumbing. There are several types of water heaters, and the right one for you depends on your home, budget, hot water use and desired level of efficiency.

Types of Water Heaters:

A water heater tank (also called a storage tank water heater or hot water tank) is the most common type of water heater in Ottawa. As the name suggests a water heater tank is a large tank that holds a certain volume of water. Equipped with a heating element, thermostat, and insulation to minimize heat loss, these heaters maintain a preset water temperature, allowing hot water to be readily available for use. 

Water heater tanks take up more space than other types of water heaters (such as tankless water heaters) however, they remain the standard choice for Ottawa homeowners due to their affordability and reliability. 

Common water heater tank sizes include 30, 40, 50 and 75 gallons. 

If you have questions about water heater tanks or are looking to buy a hot water heater tank – Call us today!

A tankless water heater (also called an on-demand water heater, instant water heater or continuous water heater) is a system that heats water only when needed, eliminating the need for a storage tank. Tankless heaters use high-powered burners or electric coils to heat water on-demand as it flows through the unit. This means that tankless water heaters are more energy efficient because they only use energy when called on, whereas a water heater tank will use energy all the time even if no hot water is used. 

These compact wall-hung water heaters are loved by many Ottawa homeowners for a couple reasons: you save on energy, you save space and you get an unlimited supply of hot water. Tankless water heater are however more expensive than the typical hot water tank. 

If you have questions about installing or repairing a tankless water heater in Ottawa – Call us today!

A combi boiler (short for combination boiler) is a compact heating system that serves both the central heating and hot water needs of a home in a single unit. This space-saving design not only provides instant hot water but also reduces energy consumption by heating only the water needed, making combi boilers a practical and efficient choice for homes with limited space and varying heating requirements.

Combi boilers are a great option for Ottawa homeowners who currently heat their homes with standard boilers or for those interested in installing in-floor heating.

Water Heater Fuel Options:

The vast majority of water heaters in Ottawa and throughout Canada are powered by natural gas. This is because natural gas was the most affordable heating fuel choice for many decades and is more efficient than its predecessors like oil. However, this has started to change with the introduction of the Canadian Federal Carbon Tax and instability in fossil fuel supply and cost. The Carbon Tax is set to triple in the next seven years and with it increase monthly utility bills for water heaters powered by fossil fuels such as natural gas and propane. It’s worth keeping these economic conditions in mind when selecting a new water heater.

Natural gas hot water tanks are the most common water heaters installed in Ottawa. This is because natural gas has been the most affordable fuel option in Ottawa for decades however, it’s important to keep in mind that utility bills on these water heaters will continue to rise as the Carbon Tax does. 

If you have questions about gas hot water tanks or are looking to buy a water heater in Ottawa – Call us today!

Propane is a popular option on the outskirts of Ottawa such as Stittsville, Carp and Manotick, where natural gas isn’t available yet. It is more expensive than natural gas but still generally more affordable than electricity. As noted above the price of propane will continue to rise as the Carbon Tax does.

The homeowner must also work with a utility provider to ensure the propane is stored safely and refilled on a regular basis.

If you have questions about propane water heaters or are looking to buy a hot water heater in Ottawa – Call us today!

Electric water heaters are becoming a much more appealing option for Ottawa homeowners as the Carbon Tax continues to increase to cost of fossil fuels.

Renting vs Buying a Water Heater

At Francis Plumbing Heating & Cooling we do not believe that water heater rental contracts are in the best interest of Ottawa homeowners which is why we do not offer rental contracts. The long-term trust of our customers is our number one goal and we want to enable you to make the smartest choice for your home and your budget!

Should You Rent Or Buy Your Water Heater?

The issue with renting your water heater is that monthly fees add up quickly over time, especially when you consider that a typical water heater lasts for 10 years. The reality is that with most rental contracts, you will have paid the same amount as an upfront purchase by year 8 but you will have to continue renting for the rest of the equipment’s life. Most analysis shows that buying can cost up to 35% less than renting, even including a maintenance plan! Ultimately, when presented with the option to buy, especially if financing is available, it is almost always more wise to purchase new equipment as opposed to renting.

Have more questions about the best way to purchase a new water heater? Give us a call! Our HVAC & water heater experts will be happy to walk you through all the details and help you select the best equipment for your home.

We used Francis Plumbing & Heating in the fall to replace our hot water tank and furnace in the same week after a friend recommended them. The experience was very smooth, professional, efficient, and the jobs were done on time, cleanly and were well priced. We also just had our air conditioner die in the first heat wave of the season and did not hesitate for a second before calling up Francis Plumbing & Heating. Once again, they delivered with exceptional responsiveness, quality, and value. Every one we've dealt with from that first phone call to receive a quote, to working with admin for payment and scheduling, to the employees in our home doing the installation have been amazing; so polite and friendly, so knowledgeable and helpful, so hardworking and efficient. HVAC and plumbing jobs are never fun because they are inconvenient and tend to cost a lot but Francis Plumbing & Heating Ltd has made our experiences very positive! We 10/10 recommend them.

Francis Plumbing & Heating has impressed me with their courteous and professional service from initial quote with advice that saved us hundreds of dollars and felt more like a masterclass in heating and ventilation than a sales pitch (thanks Ray) to follow-up communication without pressure from Ray and Jeff, to personal-touch front-office booking and communication, all the way to COVID-19 precautions during installation and obvious pride of workmanship from the technicians involved (Jeff, Ian, and Jordan H). The prices are fair, and competitive. The quality of the workmanship is top-notch. The customer service leaves the impression that Francis Plumbing & Heating is a reputable company is proud of their reputation, but doesn't rest on their laurels, and sees every project as an opportunity to earn your respect and future business.

Francis Plumbing was great! I was able to get the installation just a few days after my quote. Ian and Ray were great during the installation process, and when we discovered an issue with the installation, they were able to find me a suitable alternative and still install it on the same day.

We have used Francis Plumbing & Heating for three years now and have no regrets using them on each and every project. They are a stellar team of professionals I would 100% recommend to anyone looking for work to be done. They helped us on our new home to assess the plumbing, install outdoor faucets, get a new efficient water heater in, and to help us connect all our new appliances. We've had them back for furnace maintenance, new faucets, new toilets, etc. This week they installed a heat pump system for us and helped manage all the work to have an energy assessment for the available rebates. The new heat pump is amazing - quiet, efficient, and functions so well. The team at Francis is always friendly, kind, professional, and careful. They do clean work that is always really well managed, and they clean up fully after all their work. They are a fantastic group who communicates clearly, who let us know our options, and offer great financing too. We would work with no one else.

Water Heater FAQs

Water heaters typically last for 10-15 years however, this can vary depending on the type of water heater, the quality of installation and the frequency of maintenance. Regular maintenance and proper care can extend the lifespan of a water heater. – Learn more about water heater maintenance

Draining your water heater annually is generally recommended to remove sediment buildup that can affect its efficiency and lifespan. However, some water heaters may require more attention and others less due to factors such as the hardness of the water and the type of water heater. It’s best to consult with a water heater expert about your system’s specific needs.

Signs that your water heater may be reaching the end of its life include reduced hot water supply, unusual fluctuations in water temperature, unusual noises such as banging or rumbling, visible signs of corrosion or rust on the tank, leaks or puddles around the unit, and increased energy bills. Regular maintenance and proper care can extend the lifespan of a water heater. – Learn more about water heater maintenance
