You’re in the middle of a relaxing shower when, suddenly, the water turns ice cold. It’s a shock to the system that every homeowner dreads. If your current water heater is struggling to keep up with your family’s morning routine, or if it’s simply nearing the end of its life, you’re likely weighing your options.
The biggest question we hear at Any Hour Electric, Plumbing, Heating & Air is simple: “Is tankless water heater installation actually worth it?”
For decades, the standard 50-gallon metal drum was the only game in town. But today, tankless technology (often called “on-demand” heating) promises endless hot water and lower energy bills. But does the reality match the hype? Let’s dive into the details to help you make the best choice for your home.
What Exactly Is a Tankless Water Heater?
To decide if it’s worth the investment, you first need to understand how it differs from the traditional unit sitting in your basement.
- Traditional Tank Heaters: These units fill a large tank (usually 40 to 80 gallons) with water and keep it hot 24/7. Even when you’re sleeping or at work, your heater is burning energy to maintain that temperature.
- Tankless Water Heaters: These units don’t store water. Instead, they use high-powered burners or electric coils to heat water instantly as it passes through the pipe. When you turn off the tap, the heater shuts down.
How Much Does Tankless Water Heater Installation Cost?
Let’s address the elephant in the room: the price tag. If you’re looking strictly at the upfront purchase price, a traditional tank is almost always cheaper.
- Initial Investment: A tankless unit typically costs more to purchase than a standard tank.
- Installation Complexity: Installing a tankless system often requires rerouting gas lines, upgrading venting to stainless steel, or adding electrical circuits. This makes the labor cost higher than a simple “swap-out” of an old tank.
Now, let’s look at the Total Cost of Ownership. While the Day 1 cost is higher, the Year 10 cost often tells a very different story.
Will I Really Save Money on Energy Bills?
Yes, you almost certainly will.
Traditional tanks suffer from “standby heat loss.” Heat naturally escapes through the walls of the tank, forcing the unit to reheat the water repeatedly throughout the day.
- Efficiency Rates: A standard tank is roughly 60% efficient. A modern gas condensing tankless unit can be up to 98% efficient.
- The Savings: According to the U.S. Department of Energy, homes that use 41 gallons or less of hot water daily can be 24%–34% more energy efficient with a tankless unit.
Over the life of the unit, these monthly savings can add up to thousands of dollars, effectively paying back the difference in installation costs.
How Long Do Tankless Water Heaters Last?
If you’re tired of replacing your water heater every decade, this is a major selling point.
- Traditional Tanks: Have an expected lifespan of 8 to 12 years. Eventually, the steel tank corrodes and leaks.
- Tankless Units: Have an expected lifespan of 20+ years. Because they don’t hold standing water, they are less prone to rust and corrosion.
When you do the math, one tankless heater can outlast two traditional tanks. This means you’re paying for installation labor once every 20 years instead of twice.
Does “Endless Hot Water” Mean I Can Run Everything at Once?
The term “endless” refers to the duration of the hot water, not the volume at a single moment.
- The Duration: You can technically take a three-hour shower, and the water will stay hot the entire time. The heater never “runs out” because it creates hot water on the fly.
- The Volume (Flow Rate): This is where sizing matters. A tankless unit can only heat a certain number of gallons per minute (GPM).
If you try to run two showers, the dishwasher, and the washing machine simultaneously, you might exceed the unit’s GPM limit, resulting in lukewarm water. This is why it is important to have the experts at Any Hour Electric, Plumbing, Heating & Air properly size your unit based on your family’s peak usage.
Does It Save Space?
Absolutely. This is often the deciding factor for homeowners with smaller basements or utility closets.
A traditional tank takes up about 9 square feet of floor space and stands 5 feet tall. A tankless unit is roughly the size of a carry-on suitcase and mounts on the wall. This frees up valuable square footage for storage, shelving, or simply a less cluttered home.
Are There Any Downsides?
We believe in honest, transparent advice. Tankless heaters are fantastic, but they aren’t magic. Here are a few things to consider:
- The “Cold Water Sandwich”: If you turn the hot water off and then back on quickly, you might get a momentary burst of cold water while the heater kicks back into gear.
- Lag Time: It might take a few extra seconds for the hot water to reach your faucet compared to a tank that has hot water ready to go immediately.
- Hard Water Sensitivity: If you live in an area with hard water, mineral buildup can damage the heat exchanger. Regular maintenance (flushing the unit) is essential to keep the warranty valid.
The Verdict: Is It Worth It?
For most modern homeowners, the answer is Yes.
If you plan to stay in your home for more than a few years, the combination of energy savings, longevity, and the luxury of endless hot water makes it a superior investment. However, if you’re on a strict immediate budget or plan to move next year, a traditional tank might be the practical choice.

Tankless Water Heater Installation Frequently Asked Questions (FAQ)
1. Can I install a tankless water heater myself?
No, DIY installation is highly discouraged and often voids the manufacturer’s warranty. Tankless installation involves complex high-voltage electrical work, gas line sizing, and specific venting requirements. Improper installation can lead to carbon monoxide leaks or fire hazards. Always trust a licensed professional.
2. Does a tankless water heater require maintenance?
Yes. Unlike traditional tanks which are often ignored until they break, tankless units need to be flushed once a year to remove mineral buildup (scale). This is a simple service that ensures your unit maintains its efficiency and reaches that 20-year lifespan.
3. Will a tankless heater work if the power goes out?
Generally, no. Even gas-powered tankless units require electricity to operate the digital display, sensors, and ignition. However, some models can be equipped with a battery backup system to keep the hot water flowing during a blackout.
4. Is a gas or electric tankless model better?
In most cases, gas tankless heaters are more powerful and can handle a higher flow rate (more simultaneous showers) than electric models. Electric tankless heaters often require significant upgrades to your home’s electrical panel, which can be costly.
5. How do I know what size tankless heater I need?
Sizing is based on “Gallons Per Minute” (GPM). You need to calculate how much hot water you use during your busiest time of day (e.g., a shower running at 2.5 GPM plus a kitchen faucet at 1.5 GPM = 4.0 GPM). Our technicians can perform a usage audit to recommend the perfect size for your household.
