Never run out of hot water again. A tankless water heater installation delivers unlimited on-demand hot water exactly when you need it — no storage tank, no standby heat loss, no cold showers. Sacramento homeowners switching from traditional tank systems consistently report energy savings of 20–35% on water heating costs. According to the U.S. Department of Energy, tankless water heaters can be 24–34% more energy efficient than conventional storage tank heaters for homes that use 41 gallons or less of hot water daily.

The 5 Star Plumbing handles every step of the tankless water heater installation process — from system sizing and gas line upgrades to final testing and permit filing. Our licensed plumbers service all major brands including Rinnai, Navien, Rheem, Noritz, and Takagi.

Frequently Asked Questions

How much does tankless water heater installation cost in Sacramento?
Most whole-home tankless water heater installation in Sacramento runs $1,500–$3,500 depending on the unit, fuel type, and whether gas line upgrades are needed. Electric units start lower. We provide upfront, itemized quotes before any work begins.

What’s the difference between a gas and electric tankless water heater?
Gas units deliver higher flow rates (ideal for families) and lower monthly energy costs in most CA markets. Electric units are simpler to install, require no venting, and are well-suited for smaller households or supplemental applications.

How often does a tankless water heater need to be flushed or descaled?
In Sacramento — where water hardness is moderate to high — we recommend annual descaling to prevent mineral buildup that reduces efficiency and can shorten unit lifespan. Signs you’re overdue: reduced flow rate, fluctuating temperatures, or error codes.

Can you repair my tankless water heater the same day?
Yes. We offer same-day tankless water heater repair across Sacramento and surrounding areas. Common issues we fix: error codes (E1, E3, LC), ignition failures, cold water sandwiching, fluctuating temperature, and pressure problems.

My tankless water heater is not producing hot water — what’s wrong?
The most common causes are a blocked air supply or exhaust vent, a gas supply issue, a tripped high-temperature limit switch, or a faulty flow sensor. Call us at (888) 909-0120 for a same-day diagnostic — we’ll identify and fix the issue in one visit.
