Tankless vs Traditional Water Heaters: A Guide for HVAC Contractors

As an HVAC contractor, choosing the right water heater for your clients can be a game-changer. With energy efficiency being a top priority, understanding the differences between tankless and traditional water heaters is crucial. In this post, we’ll break down the pros and cons of each type, helping you make informed decisions for your customers.

Energy Efficiency: Tankless vs Traditional Water Heater

Energy efficiency is a significant factor in the tankless vs. traditional water heater debate. Tankless water heaters are typically 8% to 34% more efficient than their traditional counterparts. This efficiency translates to lower monthly energy costs and reduced standby heat loss. For gas models, tankless units have an annual operating cost of $195 compared to $245 for conventional tanks. Electric tankless units cost about $535 per year, slightly less than the $580 for electric tanks.

Performance and Lifespan

When considering performance, both storage tank and tankless gas models can reliably reach set output temperatures of 120°F. However, electric tankless units may face challenges in colder climates where incoming water temperatures are lower. As for lifespan, tankless heaters boast a service life of over 20 years, while traditional storage tanks typically last between 10 to 15 years.

Hot Water Supply and Maintenance

Tankless models, such as the Ruud Ultra Series, offer a continuous supply of hot water, thanks to their on-demand heating design. These units can achieve up to .82 UEF and are up to 34% more efficient than standard tanks. However, tankless units require regular descaling, especially in areas with hard water, to maintain efficiency. Traditional tanks are more prone to scale and sediment buildup, which can impact longevity and performance.

Installation and Space Considerations

Tankless heaters, like those from Ruud, are compact and reduce the installation footprint. They feature diagnostic displays and remote Wi-Fi control, making them easy to install and maintain. The Ruud EcoNet® system enhances user experience with smart alerts and proactive maintenance.

  • Tankless water heaters are more energy-efficient.
  • They have a longer lifespan than traditional models.
  • Regular maintenance is essential to ensure peak performance.
  • Tankless models offer continuous hot water supply.
  • Compact design saves space and simplifies installation.

Conclusion

When weighing the pros and cons of tankless vs. traditional water heaters, consider the specific needs of your clients. Tankless systems offer superior energy efficiency, longevity, and space-saving benefits, making them a wise choice for many homeowners. As an HVAC professional, guiding your clients towards the best water heater option can boost satisfaction and reduce service calls.
