Are tankless water heaters worth the extra money? There are some notable advantages over traditional water heaters. Consider these pros and cons while deciding which type of heater is best for your home.

Tankless Water Heater – Pros

  • Energy Savings – Average homeowners see a 30-50% drop in energy usage.
  • Unlimited Hot Water – No waiting on a tank to fill. Hot water is continuously supplied.
  • More Available Space – Units are compact and can be mounted on a wall.
  • Longer Life – Most units last 20+ years vs 10-15 for a tank model.
  • Less Maintenance – Units have fewer problems and reduced maintenance.
  • Peace of Mind – Because no water is stored

Tankless Water Heater – Cons

  • Higher Initial Cost – More expensive to purchase and install.
  • Difficult to Install – Converting to tankless requires professional installation.
  • Venting Requirements – For gas models, ventilation may need to be added.
  • Water Limitations – Small units may not be able to serve many rooms simultaneously (e.g. running the dishwasher and showering at the same time). Make sure you have a model adequate for your needs.

How Tankless Water Heaters Work

A water heater with a tank preheats water and is stored in a large tank. The hot water is delivered when needed. Tankless heaters do not store any water, they quickly heat it as it is being used.

Sometimes tankless water heaters are called “on-demand” water heaters for this reason.

A traditional tank model is less expensive to install, but uses more energy and raises utility costs. You’re constantly using energy to keep water in a tank warm, whether you use it or not. This energy usage can add up over time. Learn more about how to improve your existing water heater’s energy efficiency and save money!

Tankless models provide on-demand hot water. A traditional tank model, however, can run out of hot water and it takes time to re-fill and re-heat.

Tankless water heaters can run on electricity, natural gas, or propane. There are benefits to each type, and this should be considered for each home. Gas may increase capacity, but electric models are typically more efficient and have lower costs.

Although tankless water heaters can cost more upfront, most homeowners agree, their savings and benefits, in the long run, are usually worth the price. Consider these advantages and disadvantages when it’s time to replace your current system.
