Tired of waiting for hot water? Or worse, running out mid-shower? A tankless hot water heater could be the solution. A tankless water heater heats water only when needed.
no waiting, no running out, and no wasted energy
But are they really better? Before you switch, it’s important to know how they work, their benefits, and whether they’re worth the investment. Keep reading for expert insights from PipePros!
What Is a Tankless Hot Water Heater?
A tankless hot water heater heats water only when you need it. Instead of storing hot water in a big tank, it uses powerful heating elements either gas burners or electric coils to warm the water as it flows through. This means no waiting for a tank to refill and no wasted energy keeping water hot all day.
They take up less space, last longer than traditional water heaters, and provide endless hot water. But before deciding, it’s important to compare them with traditional storage tank models.
Tankless Water Heaters vs. Storage Tank Water Heaters
Feature | Tankless Water Heater | Storage Tank Water Heater |
Hot Water Supply | Endless hot water on demand | Limited by tank size |
Energy Efficiency | Saves energy by heating water only when needed | Uses energy to keep water hot 24/7 |
Lifespan | 10–15 years | |
Size | Compact, wall-mounted | Large, needs floor space |
Installation Cost | Higher initial cost | More affordable |
Installation Complexity | Requires special venting and electrical/gas upgrades | Easier to install |
Maintenance | Requires descaling in hard water areas | Regular flushing needed |
Tankless heaters are a great long-term investment but they aren’t for everyone. The initial cost and installation can be a drawback.
Is a Tankless Water Heater Worth the Investment?
If you’re tired of running out of hot water or paying high energy bills, a tankless system might be the upgrade you need. But are tankless water heaters worth it? That depends on your household’s water use, budget, and long-term goals.
Tankless models save energy, take up less space, and last longer than storage tanks. But, they also come with a higher upfront price and potential installation upgrades. Weighing the tankless water heater’s pros and cons can help you decide.
Pros and Cons of Switching to a Tankless Water Heater
Pros | Cons |
Endless hot water | Higher initial cost |
Saves space | May require plumbing or gas line upgrades |
Lower energy bills | Takes a few seconds to heat water |
Lasts 20+ years | Limited flow rate (multiple users may reduce pressure) |
Less risk of water leaks | Needs maintenance in hard water areas |
With the new standards enforced by the Department of Energy (DOE) regarding new gas tankless water heaters, Andrew deLaski, Executive Director of the Appliance Standards Awareness Project, emphasized the benefits of updated standards:
“This is a commonsense step that will lower total household costs while reducing planet-warming emissions.”
Replacing a typical natural draft storage water heater with a tankless model can yield a 37% savings in water heating energy per household.
It has a lot of befits to offer but what is the downside of a tankless water heater? For one, it requires a professional setup. It can’t be a DIY project. It might also struggle if multiple appliances run at the same time. Some homes may need larger gas lines or electrical updates.
How To Choose The Right Tankless Water Heater Unit
Choosing the right tankless water heater depends on your household’s size, water demand, and available fuel source. Below are key factors to consider.
Household’s Hot Water Needs
A larger family with multiple bathrooms and appliances running simultaneously will need a unit with a higher gallon-per-minute (GPM) rating. Smaller homes may be fine with a lower-capacity model.
Efficiency Ratings
Tankless water heaters have different efficiency ratings. Look for models with a high Uniform Energy Factor (UEF) for better performance.
Consider the Fuel Type: Gas or Electric?
Fuel Type | Pros | Cons |
Gas | Heats water faster, better for larger households | Needs proper ventilation, may require bigger gas lines |
Electric | Easier installation, lower initial cost | Slower heating, may struggle with high demand |
Choose the Right Size for Your Home
Make sure your unit’s flow rate meets your home’s peak demand. If your home has three or more bathrooms, a higher-capacity system is recommended.
Installation Requirements and Space
Planning to get one installed? Be ready with the things you need:
- Needs proper ventilation (for gas models)
- May require larger gas lines or upgraded electrical circuits
- Works best when installed near points of high water use
- Compact and wall-mounted, saving floor space
Warranty
A good warranty can save you money on future repairs. Most tankless models offer 10–15 years of coverage which is longer than traditional water heaters.
Should I Make the Switch?
If you want endless hot water, lower energy bills, and a longer-lasting system, a tankless hot water heater is the perfect investment. But if you’re on a tight budget or have a large household that uses a lot of hot water at once, a traditional system might work better.

Tankless Water Heater FAQs
It depends on the unit’s capacity. High-capacity tankless water heaters can supply enough hot water for multiple showers simultaneously. However, smaller units might struggle to keep up with high demand.
Yes, regular maintenance is important. Tankless water heaters should be flushed at least once a year to remove mineral buildup, especially in areas with hard water.
While tankless water heaters can operate with hard water, mineral buildup can occur more rapidly, affecting performance. Installing a water softener can help mitigate this issue and protect your system.
If your home has low hot water demand or you’re concerned about the higher upfront costs, a tankless system might not be the best choice. Additionally, homes with outdated electrical or gas systems may require costly upgrades to accommodate a tankless unit.
Possibly. Many gas-powered tankless water heaters require a higher gas flow than traditional tank models. It’s important to have a professional assess your current gas line to determine if an upgrade is necessary.
Yes, certain tankless water heaters are designed for outdoor installation. These models are built to withstand various weather conditions and can save indoor space.
Tankless water heaters heat water on demand, so there’s no waiting for a tank to fill. However, the time it takes for hot water to reach your faucet depends on the distance between the unit and the outlet. Typically, you’ll have hot water within a few seconds.
