How Tankless Water Heaters Work
-
Tankless water heaters, also known as on-demand water heaters, operate by heating your water directly without the need for a storage tank.
-
When you turn on the shower or hot water tap, cold water enters the unit through an inlet pipe. Inside the tankless water heater, a powerful electric element or a gas burner rapidly heats the water as it flows through a heat exchange.
-
The average tankless water heater produces 160,000 BTUs. BTU stands for British Thermal Unit – it is a fancy way of measuring the amount of energy your tankless water heater needs to heat your water. The hot water then travels through the outlet pipe and to your hot water taps.

4 Benefits of Tankless Water Heaters
Tankless water heaters are the future of water heaters. From their endless supply of hot water to their efficiency, they offer many benefits that you won’t find with a traditional tank water heater.
Below are some of the benefits of tankless water heaters:
- Energy Efficiency. Tankless water heaters are energy-efficient because they only heat water when you turn on a hot water tap. Traditional tank water heaters continuously use energy to maintain a set temperature. This “on-demand” heating principle reduces standby energy losses and can result in substantial energy savings.
- Endless Hot Water. One of the most notable advantages of tankless water heaters is their continuous supply of hot water. Since there is no storage tank to deplete, you can enjoy hot water for as long as you need it. This advantage is particularly beneficial if you use a lot of hot water – such as running a couple of showers at the same time.
- Space Saving. Tankless water heaters are compact and mounted to your wall. They take up significantly less space compared to their tank-based counterparts. Their small size allows for flexible installation in various locations, including tight spaces such as utility closets. By freeing up floor space, tankless water heaters can be advantageous for both new constructions and renovations.
- Longevity: Tankless water heaters typically have a longer lifespan compared to traditional water heaters. With proper maintenance, tankless units can last up to 20 years or more whereas a tank water heater lasts 8-12 years on average. This extended lifespan reduces the frequency of replacements and contributes to long-term cost savings.
Despite these advantages, tankless water heaters may have higher upfront costs compared to traditional models. However, the long-term energy savings, improved efficiency, and durability often outweigh the initial investment.

Frequently Asked Questions
-
Having instant hot water depends on where your hot water taps are located in the house. Showers or faucets close to the tankless water heater will get hot water pretty quickly. But if you have a shower, tub, or plumbing fixture on the opposite end of the house, it can take a bit longer to get hot water. For these scenarios, you can install a recirculating pump with your tankless water heater. The other option is to get a tankless water heater with a recirculating pump built into it. We’d be happy to walk you through these options during your appointment.
-
The frequency of flushing your tankless water heater depends on the quality of your water. If you have hard water, we recommend flushing your tankless water heater every year. If you have a water softener or if your water is already soft to behind with, you’d only need to flush your tankless water heater every few years. Do you have any questions, or would you like to schedule a tankless water heater service? Call us or request your appointment online.
