Considering a Tankless Water Heater? Here’s What You Need to Know

If you’ve watched a home renovation show, you may be intrigued about the benefits of a tankless water heater. Maybe you even have a friend who raves about their long showers and low energy bills. But would a tankless water heater work for your home? In this article, we’ll cover some of the most important aspects to consider to help you make the best choice.

Considering a Tankless Water Heater

What makes tankless water heaters different from traditional units?

When thinking about a water heater, we usually picture a giant tank that stores 30 or more gallons at a time. A tankless water heater works completely differently by only heating up water when needed – such as when you turn on the shower or dishwasher. As water passes through the small unit, it’s heated up immediately and then continues on through the pipes. That’s why tankless systems are sometimes called on-demand water heaters.

They are usually more expensive to install but save on energy bills

The biggest benefit of a tankless water heater is improved energy efficiency, which means you can significantly lower your monthly energy bills. This is because a tank water heater uses (some would say wastes) a lot of energy to keep all that water warm around the clock, even when you’re not home or appliances aren’t in use. Of course, that’s not the case with tankless systems, which is where the energy savings are realized.

The downside is that tankless systems come with a higher upfront cost. This is partially due to installation labor such as new venting and potentially upgrading the electrical panel.

Longer service life and less maintenance

A traditional tank water heater has an expected service life of 8-12 years. To get the full lifespan out of the unit, you need to perform regular maintenance to prevent mineral deposits from building up inside the tank. If the tank fails due to internal corrosion, it often ends up leaking, which can be messy and costly.

On the other hand, tankless water heaters can be expected to last about 20 years. This extended life can also make it a better long-term investment than a tank unit. Tankless water heaters also require regular maintenance, especially if you have hard water. However, since it does not store a large amount of water, the chance of a leak and water damage due to failure is much smaller.

Tankless technology is proven and reliable

Some homeowners may be nervous to try unproven technology. You’ll be happy to know that tankless water heaters are already popular in other parts of the work, including Europe and South America. So you can install one in your home with confidence.

Tankless water heaters come in natural gas or electrical models

You may like to know that you can choose the fuel source that works best for you. Natural gas and electric tankless units have their own advantages and disadvantages. But both are exceptionally energy-efficient and take up less space than a tank unit.
