How to Choose the Right Water Heater for Your Home

Tankless vs. Traditional: How to Choose the Best Water Heater for Your Home

When it comes to selecting a water heater for your home, the decision can often feel overwhelming. Traditional water heaters have been a household mainstay for years, providing reliable service that homeowners are familiar with. However, in recent years, tankless water heaters have become increasingly popular, offering a range of benefits such as energy efficiency and unlimited hot water. So, how do you choose between traditional and tankless options? In this guide, we’ll break down the differences between these two types of water heaters to help you make an informed decision.

Traditional Water Heaters

Traditional water heaters store a predetermined amount of hot water in a tank and continuously heat it until needed. This means that once the hot water is used up, you need to wait for the tank to refill and reheat the water before having access to more hot water. The size of the tank typically ranges from 20-80 gallons, depending on your household's needs.


  • Low initial cost: Traditional water heaters are generally less expensive upfront compared to tankless options.
  • Easy installation: Since traditional water heaters have a similar setup to older models, installation is typically quick and easy.
  • Familiar technology: Most people are familiar with traditional water heaters, making them an easy choice for replacement or upgrade.


  • Limited hot water supply: With a predetermined amount of hot water in the tank, you may run out during peak usage times.
  • Energy inefficiency: Traditional water heaters continuously heat the water in the tank, even when you're not using it, leading to energy waste.
  • Shorter lifespan: On average, traditional water heaters only last 10-15 years before needing to be replaced.

Tankless Water Heaters

Tankless water heaters use a heat exchanger to instantly heat the water as it flows through the unit. This means that hot water is available on-demand and there's no need for a storage tank. The size of the unit depends on your household's hot water needs, but they are typically much smaller than traditional heaters.


  • Continuous supply of hot water: With a tankless water heater, you'll never run out of hot water during peak usage times.
  • Energy efficiency: Since tankless water heaters only heat the water when needed, there is no energy waste.
  • Longer lifespan: Tankless water heaters can last up to 20 years before needing to be replaced.


  • Higher initial cost: Tankless water heaters are typically more expensive upfront compared to traditional options.
  • Complex installation: Installing a tankless water heater can be more complicated and may require additional modifications to your home.
  • Limited flow rate: If using multiple appliances at once, a tankless water heater may not be able to keep up with the demand and result in reduced water pressure.

Making Your Decision

When deciding between traditional and tankless water heaters, it's essential to consider your household's hot water needs, budget, and energy efficiency goals. If you have a large household that uses a lot of hot water, a tankless option may be the best choice for your home. On the other hand, if you're on a tight budget or have limited space for installation, a traditional water heater may be the better fit. Ultimately, it's crucial to research and compare both options to determine which one will best meet your specific needs. So, whether you choose the traditional or tankless route, make sure to consult with a professional to ensure that you choose the best water heater for your home. Happy heating!

Additional Tips

  • Consider adding insulation around your hot water pipes to reduce heat loss and save on energy costs.
  • Regularly flushing your traditional water heater can help improve its efficiency and extend its lifespan.
  • If you have a tankless water heater, it's important to have it serviced regularly to prevent mineral buildup and maintain optimal performance.
  • Don't forget to consider any rebates or tax credits that may be available for upgrading to an energy-efficient water heater. Overall, stay informed and make the best decision for your home and budget.
