If you’re in the market for a new water heater, you may be wondering if a tank or tankless model is right for you. Each has its own advantages and disadvantages. Read on to explore the pros and cons of both to help you make an informed decision for your home.
Difference Between Tank and Tankless Water Heaters
The main difference between traditional tank water heaters and tankless water heaters is the presence of a tank. A tank water heater stores hot water in a cylinder, while a tankless model heats water on demand. Common energy sources for water heaters include natural gas and electricity.
How Does a Storage Tank Water Heater Work?
A tank water heater has a storage tank that keeps hot water ready for use. It is connected to a cold water supply and a gas or electric heat source. As cold water enters the tank, the heater warms it up. The heated water rises to the top of the tank and is available when you need it for your sink, shower, or washing machine.
Advantages of Tank Water Heaters
- Lower Initial Cost: Less expensive to purchase and install a tank water heater.
- Higher Hot Water Tolerance: Can handle simultaneous hot water usage.
- Simpler Operation: Easier to operate and repair.
Disadvantages of Tank Water Heaters
- Wait Time: Requires time to heat up more water once depleted.
- Shorter Lifespan: Typically lasts 8 to 12 years.
- Higher Energy Bills: Consumes more energy to keep water hot.
- Space Requirement: Needs more space for installation.
- Leak Risk: Potential for leaks, which can cause water damage.
What Size Tank Water Heater Do I Need?
To determine your water heater sizing, calculate your peak hour demand by adding up the gallons-per-minute (GPM) flow rate of all the appliances and fixtures that will use hot water simultaneously. Choose a tank water heater with a first-hour rating (FHR) that meets or exceeds this demand.
How Does a Tankless Water Heater Work?
A tankless water heater heats water as needed, without storing it. When you turn on the hot water, the tankless water heater activates, using a powerful heat exchanger to warm the incoming cold water instantly. This provides a high amount of hot water on demand, flowing through your pipes to your faucet or showerhead.
Advantages of Tankless Water Heaters
- Energy Efficiency: Heats water only when needed, reducing energy consumption.
- Space-Saving: Smaller and can be installed in various locations.
- Longer Lifespan: Can last up to 20 years with proper maintenance.
- Lower Leak Risk: Less likely to leak compared to tank models.
Disadvantages of Tankless Water Heaters
- Higher Initial Cost: More expensive to purchase and install a tankless water heater.
- Installation Requirements: May need gas line or electrical upgrades.
- Lag Time: May have a delay in providing hot water.
- Maintenance Needs: Regular maintenance required to prevent mineral buildup.
What Size Tankless Water Heater Do I Need?
Calculate the flow rate needed by summing the GPM for all fixtures that will run simultaneously. Also, consider the water temperature rise required to meet your desired temperature. Choose a tankless unit that meets these specifications to ensure a steady supply of hot water.
Gas vs. Electric Water Heaters
Both tank and tankless water heaters can use gas or electricity. Each energy source has its pros and cons:
- Electric Tankless Water Heaters: Cheaper to install but have a lower flow rate.
- Gas Tankless Water Heaters: Higher initial costs but better flow rates and efficiency.
- Electric Tank Water Heaters: Higher operating costs and longer recovery times.
- Gas Tank Water Heaters: Heat water quickly but may have a shorter lifespan.
Water Heater Installation Costs
Tank Water Heaters
- Gas Models: Typically range from $2,500 to $5,500 for installation.
- Electric Models: Generally cost between $2,000 and $3,500 for installation.
Tankless Water Heaters
- Gas Water Heaters: More expensive, starting at $8,000.
- Electric Water Heaters: Often cheaper but may require electrical upgrades.
Installation Costs and Maintenance
Installing a new water heater involves various costs. Gas models may need ventilation and gas line installations, increasing costs. Electric units may require electrical system upgrades. Regular maintenance, such as flushing the system and checking the anode rod, is essential to prolong the life of your water heater.
Which Type of Water Heater is Right for You?
Deciding between a tank and tankless water heater depends on your priorities. If you want a lower upfront cost and straightforward installation, a tank water heater might be best. However, if you prefer energy efficiency and a longer lifespan, a tankless water heater could be the smarter choice. Consulting with a professional can help you determine the best option for your home.
