Frequently Asked Questions

Is a tankless water heater right for my home?
Tankless units are great for most homes, especially those with high hot water demand. However, they may require upgrades to your gas line or electrical system. We provide a thorough assessment to determine if it’s a cost-effective choice for you.
According to the Department of Energy, tankless water heaters can be 24%–34% more energy-efficient than conventional storage tank water heaters for homes that use 41 gallons or less of hot water daily.
Yes. Because they heat water so rapidly, minerals can build up on the heat exchanger. We recommend an annual flush (descaling) to maintain efficiency and prevent damage. This is often required to keep the manufacturer’s warranty valid.
We install and service top-rated brands known for reliability, including Navien, Rinnai, and Noritz. We only recommend units that have a proven track record of performance.
