Tankless Water Heater Installation — Santa Rosa CA

Endless hot water. Lower energy bills. 20-year lifespan. We install all major brands throughout Sonoma County.

Why Upgrade to Tankless?

Traditional tank water heaters keep 40–50 gallons hot around the clock, wasting energy even when no one is home. Tankless (on-demand) heaters fire only when you turn on the hot water tap, delivering continuous hot water at up to 30% lower energy cost.

For Sonoma County households tired of cold showers, high gas bills, or a water heater taking up half the garage, going tankless is one of the best upgrades you can make.

Frequently Asked Questions

How much does tankless water heater installation cost?
Tankless water heater installation in Santa Rosa typically runs $1,500–$3,500 installed, depending on the unit and whether gas line or venting upgrades are needed. We provide free in-home estimates.
What are the benefits of going tankless?
Tankless units provide endless hot water on demand, use 20–30% less energy than tank heaters, last 15–20+ years, and free up significant storage space.
Can I install a tankless water heater where my old tank is?
Yes, in most cases. Your existing gas line may need to be upsized (tankless units draw more BTUs), and new venting is usually required. We assess this on the estimate visit.
What brands do you install?
We install and service Navien, Rinnai, Noritz, Rheem, Bosch, and other major tankless brands.
Do tankless water heaters work with solar?
Tankless gas units work independently of solar. If you have solar thermal, we can discuss hybrid options. For solar PV homes, a heat pump water heater may be an even better fit.
How long do tankless water heaters last?
With annual descaling (critical in Sonoma County due to hard water), tankless units typically last 15–20 years or more.
