Five Signs You May Need a Tankless Water Heater

If you’ve been thinking about upgrading your home’s hot water system, you’ve probably come across tankless water heaters for sale. But how do you know if it’s time to make the switch? Here are five signs you may need a tankless water heater in your home.


1) Do you have a large family and/or often run out of hot water? 

Large households tend to use a lot of hot water—showers, laundry, and dishes add up quickly. Traditional tank water heaters store a limited amount of hot water. Once the tank runs out, you’re stuck waiting for it to reheat.

Tankless water heaters, on the other hand, heat water on demand. That means no more staggering showers or fighting over who gets the hot water first. If you’re searching for tankless water heaters for large homes, this upgrade may be perfect for you.

2) Do you have a bulky heater in a small space?


Standard water heaters often take up valuable floor or closet space. A tankless system is wall-mounted and much more compact. Even better, they can be installed inside or outside, depending on your home setup.

Can tankless water heaters be installed outside?

Yes! Many models are designed for outdoor installation, especially in warmer climates like Texas.


3) Do you want to save energy and money?


One of the biggest benefits of going tankless is energy efficiency. Traditional tanks constantly heat stored water, even when you’re not using it—wasting energy and money. Tankless heaters only heat water when you need it.

Why are tankless water heaters better?

Because they reduce energy waste, save you money on monthly bills, and last longer than traditional models. Many also qualify for tax credits and rebates.

4) Do you worry about your water heater leaking and destroying your flooring, walls, and ceiling, plus causing black mold?

Tank water heaters can leak, leading to costly damage and even black mold growth. Since tankless systems don’t store water, the risk of leaks is much lower.

Tankless water heaters create hot water fresh on demand, giving you peace of mind and protecting your home.

5) Are you tired of repairing or replacing your heater after your 6-year warranty runs out?

Traditional water heaters typically last around 6–8 years. Many tankless systems, like Navien, offer 15-year warranties on heat exchangers and can last up to 20 years with proper maintenance.

Yes, the initial investment is higher, but you’ll save on repairs, energy costs, and replacement fees over the long run.

Gas vs. Electric Tankless Water Heaters


 Are tankless water heaters gas or electric?

Both! Tankless units come in gas and electric models

Can tankless water heaters be electric?

Yes. Electric tankless heaters are available and can be a good choice for smaller households or spaces without a gas line. Gas models are usually better for larger homes with high hot water demand.

If you’re searching for tankless water heaters near me, make sure you choose a certified installer who can recommend the right model for your household.
