FAQs
How does a tankless water heater improve energy efficiency compared to a traditional storage tank?
Unlike storage tanks that keep 40–80 gallons of water hot all day, a tankless unit heats water only when a hot-water tap is opened. This on-demand operation eliminates standby heat loss and can cut water-heating energy use by 24 %–34 %. Many high-efficiency models reach Energy Factors of 0.95 or higher, and several qualify for federal tax credits and Monterey Bay Community Power rebates.
Is a tankless water heater a good choice for Monterey’s coastal climate?
Yes. Monterey’s mild inlet-water temperatures (typically 55 °F–60 °F) allow a tankless unit to deliver a comfortable 120 °F output without being oversized. Because salty sea air can accelerate corrosion, we recommend stainless-steel or coated heat exchangers and locating the vent termination away from direct ocean spray. Licensed local installers also apply corrosion-resistant fasteners and sealants suited to coastal conditions.
What size tankless unit do I need for my Monterey home?
Sizing is based on simultaneous hot-water demand (gallons per minute, GPM) and desired temperature rise. A typical two-bath, three-bedroom house in Monterey uses 7–9 GPM if two showers and a sink run together. A 180,000 BTU (approx. 8 GPM at a 60 °F rise) condensing unit usually suffices, while larger households or spa owners may need 199,000 BTU (10-11 GPM). Our technicians perform a fixture count, usage-pattern review, and inlet-temperature measurement to select the right model.
Do I need a permit to install a tankless water heater in Monterey County?
Yes. The Monterey County Building Services Department requires a plumbing/mechanical permit for any water-heater replacement, including tankless models. The unit’s gas line, venting, seismic bracing, and condensate drain (for condensing units) must meet California Plumbing Code. After installation, a county inspector will verify clearances, combustion-air supply, and proper vent termination. Working with a licensed C-36 plumbing contractor streamlines the permit and inspection process.
How long does installation take, and will my water be shut off?
Most residential retrofits are completed in one workday. Water is typically off 2–4 hours while the old tank is removed and new water/gas connections are made. Gas may be off slightly longer for pressure testing. Our crew schedules the shutdown around your needs, and temporary bypass piping can be arranged for critical facilities. Once gas and water lines are re-charged, the unit is commissioned and hot water restored the same day.
What maintenance is required to keep a tankless water heater running efficiently?
A tankless heater should be descaled annually (or every 6 months if your home has hard water) to remove mineral buildup from the heat exchanger. The process involves circulating a mild vinegar solution for 30–45 minutes, cleaning the inlet screen filter, and checking the condensate trap (if applicable). Regular maintenance maintains peak efficiency, prevents error codes, and protects the heat exchanger warranty—most manufacturers require documented service by a qualified technician.
