Pros and Cons of Tankless Water Heaters

Gone are the days when you’d need to feed a large burner with firewood to heat the water in your home. Now, there are tankless water heaters available on the market.

They have many names like instant-on, inline, or flash water heaters. The idea of these devices is to heat water instantly as it goes through the heater rather than having constantly heated water sit in a tank waiting to be used. Inside is a coil that generates heat that increases the temperature of the water.


These high-tech devices are becoming more popular in households and businesses. They have many advantages compared to the old types of heaters. Still, they have some drawbacks that you should consider. Before deciding on getting one for your home, here’s a list of the pros and cons of tankless water heaters.


Hot Water in an Instant

You can get instantly heated water when you use a tankless water heater. Once you’ve flushed out the remaining cold water from your pipes, you can enjoy hot water immediately. It would only take a few seconds.


Standard water heaters can last up to about 10 years. These are high-quality heaters which are quite expensive. Tankless water heaters can last more than that, usually two times as long. This can save you a lot of money because you won’t need to replace it after a decade or less.


Unlike standard water heaters, tankless ones can ultimately save you more money. This is because of their energy-efficient technology.

Continuous Hot Water Supply

Water heaters that rely on storage tanks would run out after some time. This will happen a lot faster if many people in the household use hot water. Using tankless water heaters can give you a continuous supply of hot water. You’ll never have to worry about refilling water tank once it runs out.


Smaller homes can now enjoy hot water with tankless water tanks. They’re smaller than conventional water heaters. They’re also usually mounted on walls so it won’t take up any floor space.

No Standby Loss

Conventional water heaters continuously heat your water even when you’re not home. Tankless water heaters only heat water when needed. This results in lower utility costs.


Inconsistent Heating

Users often complain about the inconsistent temperatures their tankless water heater provides. The problem often stems from the inability to supply heated water to many outlets at the same time.

<>Expensive Initial Costs

Tankless water tanks are expensive. The cheapest ones you can find will cost about $1,000. More advanced models can cost even more. The installation fee of specialized tankless heaters is also pricy.

Not Advisable for Big Families

If you have a big family, you may need to install more than just one tankless water heater. That’s because it can only heat water a few gallons at a time. This is great for one person who’ll wash the dishes or take a shower.

May Require Some House Renovations


Installing a tankless water heater may require you to hire people to reroute your gas lines or make other changes to your house. This can add more costs and inconvenience to you and your family.
