Hard water is a challenge for Denton residents and can lead to mineral buildup in their water heaters. In winters when water heaters are more than necessary, having a broken heater will create only havoc, requiring plumbing repairs. Here, most people start comparing tank vs tankless water heaters and get into a dilemma to select the appropriate one.
The two types possess their strengths and limitations, and the decision highly relies on your budget, the number of people living in the home, and long-term energy saving objectives. Today, we are going to discuss the main differences, advantages, and disadvantages of tank and tankless water heaters to make an informed choice of which one can suit your home.
Tank Water Heaters
Traditional tank water heaters keep a huge amount of water (typically 30-80 gallons) in a tank. It keeps the water hot 24 hours a day, even when you are not using it. Whenever you switch your hot water tap, the hot tank water is always at the top, and cold water replenishes the tank. Although this system is easy to use, it may experience a shortage of hot water in case there are too many people using it simultaneously.
Tank Water Heater Advantages:
- Lower Initial Cost: Tank water heaters start at a fraction of the cost and may range, depending on the unit, between $400 and $1000.
- Simple Installation: These units are simpler and faster to install, which may lower labor expenses.
- Works for High Hot Water Demand: Tank heaters are more suitable in households with several people using hot water simultaneously (e.g., multiple showers or when operating the dishwasher).
Tank Water Heater Disadvantages:
- Energy Inefficiency: The tank keeps heating water, hence consumes more energy. This may result in increased power or gas bills.
- Limited Hot Water Supply: When the tank empties, you will have to wait until it warms up again..
- Takes Up Space: These units are large and need a special place in your house, such as a garage or utility room.
- Shorter Lifespan: The average life of tank water heaters is about 10-15 years, but with the proper care, these products can last longer.
Tankless Water Heaters
On the other hand, tankless water heaters don’t store water at all. These units heat water as it flows through them, providing hot water only when you need it. Because they operate on demand, there’s no risk of running out of hot water. This makes them a great option for households that require hot water continuously.
Tankless Water Heater Benefits:
- Energy Efficiency: Tankless water heaters only use energy when hot water is needed. This is potentially highly efficient in terms of energy conservation in the long run, and hence makes them more efficient (up to 34% efficient than conventional tanks).
- Endless Hot Water Supply: As long as your tankless unit is sized properly, you’ll never run out of hot water.
- Space-Saving Design: These are much smaller and can be attached to the wall, leaving the space in your home free.
- Longer Lifespan: Tankless heaters will have a lifespan of 20 or more years, which is twice the life of traditional tanks.
Tankless Water Heater Drawbacks:
- Higher Upfront Costs: The tankless units are more expensive, ranging from $1,000 to $3,000. You can also make extra payments in installments, including a gas line or electric upgrades.
- Installation Complexity: Installing a tankless water heater can be more complicated, especially if your home requires system upgrades to accommodate the unit.
- Potential Output Limitations: A tankless heater may not be able to satisfy the demand if there are several hot water outlets operating at the same time (e.g., two showers at the same time).
- More Complex Maintenance: While tank heaters require only annual flushing, tankless models need professional inspection and descaling, especially in areas with hard water.
Cost Comparison: Upfront, Installation, and Operating Costs

- Tank Water Heaters: Tank water heaters are generally cheaper to install and generally cost between $400 and $1000.
