Water Heater Replacement

Our water heater went out with a house full of kids and no hot water. Water Heater Rescue answered right away, came out the same day, explained everything clearly, and gave a flat price upfront. No hidden fees, no runaround. We had hot water again that afternoon.

FAQ

Common questions about tankless water heater installation

How much does tankless water heater installation cost?

Tankless installation typically costs more than a standard tank replacement due to venting, gas line work and the unit itself. We give you a full upfront quote before any work begins so there are no surprises.

Will a tankless water heater save me money?

Yes, in most cases. Tankless units are 24–34% more energy efficient than tank heaters for average households. Over a 20-year lifespan, the energy savings typically offset the higher upfront cost.

Can my existing gas line handle a tankless water heater?

Not always. Tankless units have a high BTU demand during operation, which sometimes requires upgrading the gas line. We assess this during the site visit and include any required gas line work in the quote.

What brands of tankless water heaters do you install?

We install and service Navien, Rinnai, Rheem, Noritz and other major brands. We'll recommend the unit that best fits your home's needs and your budget.

How long does tankless installation take?

Most installations take 4–6 hours. Jobs requiring gas line modification or new venting runs may take a full day. We'll give you a time estimate before scheduling.

Do tankless water heaters require maintenance?

Yes - tankless units should be descaled (flushed) once a year in areas with hard water to prevent mineral buildup and maintain efficiency. We offer annual maintenance service.
