Are you tired of running out of hot water during showers—or paying to keep a big water tank heated 24/7? If so, it might be time to consider a tankless water heater.
At John’s Home Comfort, a growing number of homeowners in Vaughan, Etobicoke and Toronto areas making the switch, and for good reason. Here is what you need to know about going tankless—and why it might be the right choice for your home.
What Is a Tankless Water Heater?
Unlike traditional storage tanks that always heat and hold 40–60 gallons of water, but tankless units heat water on demand. That means no storage tank and no standby heat loss. When you turn on the tap, hot water is instant as it flows through the unit.
Benefits of Tankless Water Heaters
Tankless water heaters offer advantages that make them an appealing choice for homeowners. One of the biggest benefits is endless hot water—since these systems heat water on demand, you will never run out mid-shower or during back-to-back use. They are also energy-efficient, using up to 30% less energy than traditional water heaters because they only heat water when it flows, reducing your energy bills.
Additionally, tankless units boast a longer lifespan, typically lasting over 20 years with proper maintenance, compared to the 10–12 years of conventional systems. Tankless Units are compact, wall-mounted design also means they use up far less space, making them ideal for smaller homes with tight utility areas. Lastly, they provide cleaner water—because there is no large tank holding standing water, there is less chance of rust and sediment buildup, keeping your hot water fresher and safer.
Things to Consider Before Switching
While tankless water heaters offer benefits, there are key factors to keep in mind. First, the upfront cost is typically higher than traditional systems, including installation and potential upgrades to gas lines or electrical systems. However, the long-term energy savings, reduced maintenance costs, and extended lifespan often make up for the first investment over time.
Proper sizing is essential to ensure consistent hot water supply throughout your home. Choosing a unit that matches your household’s hot water demands—based on the number of bathrooms, fixtures, and simultaneous usage—is critical. At John’s Home Comfort, we will assess your home’s needs and help you select the right model for best performance.
Annual maintenance is important to keep your tankless system running efficiently. This includes descaling the unit—especially in areas with hard water—to prevent mineral buildup that can reduce performance or damage components. Regular service will help extend the life of your system and maintain peak efficiency.
