FAQs
What does your “rock-solid” warranty cover on a tankless water heater installation?
Every installation comes with two layers of protection. First, you receive the full manufacturer’s warranty—typically 10–15 years on the heat exchanger and 5 years on parts. Second, we add our own 5-year labor warranty that covers 100 % of workmanship, diagnostics, and any related repairs. If a part we supplied fails within the coverage period, we handle the paperwork, order the replacement, and return to your home at no charge. The warranty is transferable once, so if you sell your Hillsboro home the next owner enjoys the same coverage.
How long does a tankless water heater installation usually take in Hillsboro?
Most standard change-outs—from an existing gas tank to a new gas tankless unit—are completed in one working day (about 6–8 hours). If your project requires a gas-line upsizing, vent re-routing, or an electrical circuit, we may need a second day. You will have hot water by the time we leave each evening. We schedule city inspections for the next available slot; in Hillsboro that is normally within 24–48 hours.
Do I need permits or city inspections, and do you take care of them?
Yes. The City of Hillsboro Building Department requires a mechanical permit for any new or replacement water heater and may require a plumbing permit if we modify gas or water lines. As a licensed and bonded plumbing contractor in Oregon, we pull all required permits, coordinate inspections, and include the cost in your written estimate. You will receive a permit number and a copy of the finalized inspection report for your records.
How much can I expect to save on utility bills with a tankless system?
Savings vary with usage patterns, incoming water temperature, and fuel costs, but most Hillsboro homeowners report 20–40 % lower natural-gas bills compared with a conventional 40- or 50-gallon tank. Because tankless units heat water only when you open a fixture, you eliminate standby losses. ENERGY STAR® estimates a typical family can save about $95 per year; larger households and homes that frequently run out of hot water see the biggest return on investment.
What maintenance is required to keep my tankless heater and its warranty in force?
Manufacturers require an annual service that includes flushing the heat exchanger with a mild descaling solution, cleaning the inlet screen, and running a full diagnostic. In Hillsboro’s moderate-hard water (6–8 grains per gallon), we recommend a flush every 12 months; homes with water softeners can extend to 18–24 months. We offer a low-cost maintenance plan that logs each service, protects your warranty, and maximizes efficiency.
How do I know what size and model of tankless unit is right for my home?
We perform a free on-site assessment that measures ground-water temperature, total fixture flow rate, and simultaneous demand scenarios (e.g., shower + dishwasher). From that data we calculate the required gallons-per-minute (GPM) at a 70 °F rise—usually 7–9 GPM for a three-bath home in Hillsboro. We then provide two or three model options from trusted brands such as Rinnai, Navien, or Noritz, explaining differences in efficiency, recirculation features, and price. Our goal is to match you with the most reliable unit that meets your hot-water needs without overspending.
