When it comes to something as essential as hot water, the way your system is set up matters. Whether you’re building a new home in Waco, replacing an outdated unit, or upgrading for efficiency, the water heater installation you choose will impact comfort, costs, and convenience for years to come.
At Smelscer Plumbing, we’ve helped Central Texas families make this decision for decades. We know the pros and cons of both tank and tankless systems, and more importantly, we know how to help you choose what fits your lifestyle and home best.
So what’s the real difference between tank and tankless, and how do you make the right choice?
Understanding the Basics
A traditional tank water heater stores a large amount of hot water, usually 30 to 50 gallons, ready to go whenever you need it. When you use hot water, it draws from the tank. When the supply runs low, the heater refills and reheats.
A tankless system, sometimes called on-demand, heats water as needed. Cold water passes through a heat exchanger, warming instantly before it comes through your faucet or shower. No tank, no waiting for refills.
Each system has its benefits and limitations, and at Smelscer Plumbing, we’ve seen both work beautifully — when matched with the right home and water usage habits.
Tank Water Heaters: Tried, True, and Still Popular
Tank water heaters are common for a reason. They’re cost-effective to install, relatively simple to maintain, and come in various sizes to suit small households or large families.
In many Waco homes, especially older ones, a tank system is already in place. Replacing an existing tank with a similar model tends to be straightforward and budget-friendly.
For homes with consistent, moderate water use, tank heaters can do the job efficiently without a major overhaul.
However, they do have limitations. Once the hot water in the tank runs out, you wait. In households where multiple showers run back to back or laundry and dishes compete for hot water, this can become a daily frustration.
They also tend to use more energy over time, as the system keeps water hot even when no one’s using it. That’s called standby heat loss — and it’s a key factor when looking at energy efficiency.
Tankless Water Heaters: Efficient, Compact, and Fast
Tankless water heater installation is gaining popularity in Waco for good reason. These systems are smaller, energy-efficient, and provide endless hot water, at least in theory.
Since they heat water only when you need it, there’s no standby energy loss. And because the system is compact, it can free up valuable space, especially in smaller homes or utility areas.
If your home has high water demand, or if you’ve ever stood in a cold shower while waiting for the tank to refill, tankless might sound like a dream come true.
Still, there are some things to consider. Tankless systems often require higher upfront costs, both in the unit itself and in the installation process. In many cases, homes need upgraded electrical systems, gas lines, or ventilation.
Smelscer Plumbing handles all aspects of tankless conversion, from inspecting your home’s layout to safely upgrading connections. We’ll let you know upfront what it would take to make the switch, and whether it makes financial sense for your situation.
Installation Factors to Consider
So how do you choose between these two options? It helps to look at five big questions.
1. How many people are in your home?
Larger families with overlapping hot water use may benefit from the endless supply of a tankless system. But some high-capacity tank models may still handle the load with ease.
2. How much space do you have?
Tankless units save space, especially useful in smaller homes, utility rooms, or garages that double as storage.
3. What’s your upfront budget?
Tank units typically have lower initial costs. Tankless costs more up front, but savings may add up over time through energy efficiency.
4. Do you plan to stay in the home long-term?
If you’re investing in a forever home, the long-term benefits of tankless can outweigh the initial price. For short-term stays or rental properties, a tank may make more sense.
5. Do you want energy savings and lower utility bills?
Tankless systems are more energy efficient overall. If you’re looking to reduce monthly costs or take pressure off your utilities, tankless may align with your goals.
Maintenance and Service Life
Both systems need regular care to run at their best. Tank water heaters may develop sediment buildup over time, especially in areas with hard water. Regular flushing helps prevent this.
Tankless systems need descaling to avoid mineral buildup that can restrict water flow or reduce heating efficiency.
At Smelscer Plumbing, we offer maintenance for both styles of water heaters. Whether you’ve got a ten-year-old tank system that’s still running strong or a newer tankless setup that needs fine-tuning, our technicians are trained to keep it performing at its best.
One big advantage of tankless? Longer lifespan. Tank heaters typically last 8 to 12 years, while tankless models often reach 15 to 20 years with proper care.

Signs It’s Time for a New Water Heater

Water isn’t staying hot as long
-
You hear strange popping or rumbling noises

Rusty or discolored water from taps
-
Leaks or moisture around the base of your unit
-
A system over 10 years old that’s out of warranty
