Instant Hot Water System vs. Tank System: Which Is Better?
Who doesn’t love a steaming hot shower after a long day? Though we may not think about it much, hot water is an essential part of daily life. And suddenly not having any makes it a noticeable loss!
If your current hot water tank is starting to have issues or is nearing the end of its life, you may be doing research on an instant hot water system in place of your tank system. The real question is, which is better?
It can be difficult to make a decision without fully understanding the pros and cons of each option. Let’s talk about factors you need to understand like the differences between each type of hot water system installation, function, affordability, and lifespan.
Storage Tank Water Heaters
Tank water heaters are the most common systems used among homeowners due to their affordable cost and familiarity, they’ve been around forever. These tank water heaters use an electric element or gas burner to warm the water in the tank and store it until it’s needed. When hot water is used for showering, dishwashing, laundry, or other uses, the tank must heat more water before it’s available again.
The size of the tank depends on your household demand. A large family will need hot water more frequently than a smaller family or single person. Electric and gas hot water models can range in size from 25 litres to 400 litres.
Pros of tank water heater systems
Hot water is quickly available for use and ready to go
Should have regular maintenance to flush the tank at least yearly
When hot water runs out, it can take a while to fully heat another tank
Instant Hot Water System
Also known as tankless water heaters, instant hot water systems are gaining in popularity. They are capable of heating water on demand, meaning you will never run out of hot water as long as there is a constant flow. These systems don’t require a large holding tank and can fit in tight spaces. Like tanks, they can run on electricity or gas.
Pros of instant hot water systems
Highly energy efficient since water is only heated when it’s needed
No large storage tank
Less chance of leaks, corrosion, and rust
Longer lifespan than tank heaters (often up to 20 years)
Unlimited hot water on demand
Cons of instant hot water systems
More expensive to install
Requires higher flow rates
What to Consider When Choosing a System
Here are some things to consider when choosing a hot water system:
Number of people in your home
The bigger the household, the larger demand there is for hot water. If you live with a lot of people or have a big family, tankless might be the way to go.
Space for hot water system
Continuous hot water heaters take up much less space than tanks. You’ll want to consider if you’d rather have more space that isn’t taken up by a large water tank.
Upfront costs
Though an instant hot water system is an excellent choice, upfront costs might be a factor when making your decision. Even though you may save money over the life of the hot water system, the initial costs can be high.
