Tankless water heaters have many advantages. One of the key benefits is the endless hot water they provide, ensuring you never run out.
Unlike traditional models, they don’t use bulky storage tanks to hold hot water. Instead, they heat water only when needed, providing a steady supply without running out. This design makes them more energy-efficient, helping homeowners cut down on utility costs over time.
Their compact size makes them a great option for small homes, apartments, or any space where a traditional water heater might take up too much room. They also last longer, often outliving conventional models by nearly twice the lifespan. That means fewer replacements and better long-term savings.
If you’re thinking about upgrading your water heating system, Tennessee Standard Plumbing can help you decide if a tankless model is right for your home.

What Are Water Heaters?
Water heaters play a major role in daily life. Whether you’re taking a hot shower, washing dishes, or doing laundry, a water heater makes it all possible. These appliances generally fall into two main types:
Traditional Storage Tank Heaters – Also known as conventional storage water heaters, these hold 40 to 50 gallons of heated water, keeping it ready for use. However, once the hot water runs out, it takes time to reheat, which can be inconvenient for large households.- Tankless Water Heaters – Instead of storing hot water, these heat water only when needed. They provide a continuous flow, usually 2 to 3 gallons per minute, keeping up with demand without wasting energy. Tankless water heaters use a heat exchanger to heat water on demand, enhancing their efficiency.
Traditional Storage Tank Heaters – Also known as conventional storage water heaters, these hold 40 to 50 gallons of heated water, keeping it ready for use. However, once the hot water runs out, it takes time to reheat, which can be inconvenient for large households.Tankless water heaters use 22% less energy than gas-powered storage models. Homeowners can save over $100 annually on gas-powered tankless models and $44 on electric ones.
With a lifespan of 20 to 30 years, tankless water heaters often last twice as long as traditional ones. They also help reduce wasted energy, making them a good option for homeowners looking to cut down on energy use.
Comparing Water Heater Types
When choosing a water heater, it helps to understand how tank water heaters, also known as traditional storage tanks, and modern tankless systems differ. Here’s how they compare across key factors:
Storage Capacity
- Traditional Water Heaters – These come in sizes ranging from 30 to 80 gallons. Once the tank empties, you have to wait for it to refill and reheat. While good for homes that use a large amount of water at once, they aren’t the most efficient.
- Tankless Water Heaters – These heat water only when needed, meaning they don’t have a storage limit. However, they do have flow rate limits. A single unit may not be enough for a large family with multiple showers running at the same time.
For homes that use a lot of hot water throughout the day, a larger tank or multiple tankless units may be needed.
Energy Use & Cost Savings
One of the biggest reasons homeowners switch to tankless water heaters is energy savings.
- Tankless models heat water on demand, which eliminates wasted energy.
- Traditional tanks constantly keep water hot, which increases energy use over time.
- Gas tankless units can save homeowners more than $100 per year on energy bills compared to gas storage models.
- Electric tankless water heaters save around $44 per year, making them a good option for reducing costs.
While tankless models cost more upfront, they pay for themselves over time with lower energy bills and fewer replacements.
Lifespan & Durability
- Tankless Heaters – Built to last 20 to 30 years, nearly twice as long as traditional models.
- Traditional Water Heaters – Typically last 10 to 15 years, meaning they require more frequent replacements.
Since tankless systems have fewer parts exposed to standing water, they wear out more slowly, reducing maintenance costs over time.
Why Choose a Tankless Water Heater?
Tankless water heaters have several advantages over traditional models:
Condensing tankless water heaters offer additional efficiency benefits by recycling heat from exhaust gases, leading to cost savings on energy bills and greater overall efficiency.
1. Energy Savings
Tankless systems heat water only when needed, reducing wasted energy. Homeowners can cut water heating costs by up to 30% compared to traditional tank models.
Gas tankless water heaters, in particular, offer powerful and efficient water heating, utilizing natural gas or propane and requiring proper installation with access to a gas line and adequate ventilation.
2. Continuous Hot Water
No more running out of hot water mid-shower. Tankless models provide a steady supply of hot water by heating water on demand when the hot water faucet is turned on, making them a great choice for families who need a reliable system.
3. Compact Size
Tankless models mount on walls, freeing up valuable space in homes, garages, or utility closets. This makes them ideal for smaller homes or apartments where space is limited.
4. Lower Maintenance Costs
With a longer lifespan and fewer parts to replace, tankless water heaters require less maintenance. They also reduce the risk of leaks compared to storage tanks.
5. Long-Term Savings
Although the upfront cost is higher, homeowners recoup their investment through lower energy bills and fewer replacements over the years.
Choosing the Right Tankless Water Heater
Before switching to a tankless heater, think about these key factors:
1. Household Hot Water Use
- If your home uses 41 gallons or less per day, a single tankless unit should be enough.
- For larger families or homes that use a lot of water, multiple units may be needed.
2. Plumbing Compatibility
- Some older homes may require pipe upgrades to handle a tankless system.
- A professional plumber can check whether your home is ready for installation.
3. Gas vs. Electric Models
Gas tankless units provide higher flow rates and work well for homes with natural gas connections. Installing an indoor tankless water heater may require upgrades to existing plumbing or electrical systems to ensure proper venting, drainage, and maintenance.- Electric models are good for homes without gas lines, but may not supply as much water at once. Outdoor tankless water heaters, on the other hand, are suited for external installation with vents for free airflow and require draining in colder climates to prevent freezing.
