Tankless Water Heaters in Pittsburgh, PA

The cost depends on the unit's size and type, whether your gas line needs to be upsized, and how much venting and electrical work your home needs. We give you an exact, upfront price after looking at your home, and we offer financing through GoodLeap and regular tankless offers to make the upgrade more affordable.

Most installations are finished in one day. Jobs that need a new gas line or a long vent run can take a little longer, and we'll tell you the timeline before we start.

Yes. Because they heat water only when you need it, tankless units avoid the standby heat loss of a tank. The U.S. Department of Energy estimates they're 24% to 34% more efficient than tank models in homes that use 41 gallons of hot water or less per day.

Yes, if it's sized correctly. Incoming water is much colder in winter, so the unit has to raise the temperature further. We size every system for your peak winter demand, and larger homes sometimes use two units together.

For whole-home use in most Pittsburgh houses, gas tankless units deliver more hot water at once. Electric models need no venting and work well for smaller homes or a single bathroom, but they often need a dedicated high-amperage circuit or a panel upgrade.

We stock Navien tankless systems because of their reliability and performance, but we're happy to install any brand, including units you've already bought. Whatever the model, we make sure it's sized and installed correctly.

Most tankless repairs cost between $200 and $600, depending on the part and the complexity of the problem. Major repairs on advanced systems can cost more. We always give you the price before starting work.

The most common causes are scale damage inside the heat exchanger, a loose fitting, a relief valve releasing excess pressure, or a clogged condensate line on a condensing model. Shut off the unit and the water supply to it, then call us so we can find the source before it causes water damage.

Error codes point to specific problems such as ignition failure, a venting blockage, low gas pressure, scale buildup or a sensor fault. Write down the code and call us. We'll review the unit's code history as part of the diagnosis.

With annual descaling, most tankless water heaters last about 20 years, roughly twice as long as a typical tank. Skipped maintenance and hard water can shorten that considerably.

Most manufacturers recommend professional maintenance and descaling at least once a year. Homes with harder water may need it more often, and we'll recommend a schedule based on what we see inside your unit.

Homeowners can clean the inlet screen and the outside of the unit. Descaling, inspecting gas and venting connections and checking internal components should be done by a professional to avoid damage and keep your warranty intact.
