FAQs

What are the main advantages of installing a tankless water heater in Monterey’s coastal climate?

A tankless (on-demand) water heater heats water only when you open a tap, eliminating the standby heat loss that storage tanks experience. That translates to energy savings of 20–40 % versus a conventional tank. Monterey’s moderate groundwater temperature (typically 55–60 °F) lets modern condensing units reach efficiencies above 95 %. In addition, tankless models are wall-mounted, freeing up floor space, and their sealed combustion design resists salty coastal air, reducing corrosion—an important consideration so close to the ocean.

How do I determine the right size (flow rate) tankless unit for my home?

Sizing is based on two factors: (1) the total gallons-per-minute (GPM) you need when multiple fixtures run at once, and (2) the required temperature rise—the difference between inlet temperature (≈ 60 °F in Monterey) and desired hot-water temperature (120 °F is typical). For example, running two showers (2 GPM each) and a sink (1 GPM) simultaneously requires roughly 5 GPM at a 60 °F rise. We perform an in-home load calculation and recommend a unit—usually 7–11 GPM for most three-bath Monterey houses—to guarantee uninterrupted hot water even on chilly mornings.

Will my existing gas or electrical service support a new tankless system?

Many gas-fired tankless models need a ¾-inch gas line and 150–200 k BTU/hr input, which is higher than a 40- or 50-gallon tank. During our site visit we check meter capacity, gas regulator size, and venting route. If upsizing is required, we pull permits and handle the upgrade with PG&E. Electric tankless heaters demand 150–200 A dedicated service—often impractical unless you already have a 300-400 A panel. In those cases we usually recommend high-efficiency gas or hybrid heat-pump units instead. All installations meet California Plumbing & Energy Codes (Title 24) and the City of Monterey permit requirements.

Does Monterey’s moderately hard water affect a tankless unit, and should I install a water softener?

The peninsula’s municipal water averages 10–14 grains per gallon—classified as moderately hard. Mineral scale builds up faster in a tankless heat exchanger than in a tank because the water is flash-heated. To protect your investment, we install a scale-inhibiting filter or a full water-softening system at the inlet. Maintenance becomes easier and your heater retains its rated efficiency. Our technicians can test your water on-site and recommend the most cost-effective treatment solution.

How much can I expect to save on utility bills after switching from a standard tank?

Energy savings depend on usage, fuel type, and unit efficiency. A typical Monterey household using 45–55 gallons of hot water daily can cut natural-gas consumption by 150–200 therms per year. At current PG&E rates (~$2.50/therm), that’s $375–$500 annual savings. Electric-to-gas conversions save even more because electric resistance tanks are only ~90 % efficient at the point of use but rely on high-cost electricity. Over a 15-year lifespan, most customers recover the higher purchase price and installation cost through lower energy bills.

What maintenance does a tankless water heater require, and do you offer service plans?

To keep your warranty valid and maintain peak efficiency, manufacturers recommend an annual service that includes descaling the heat exchanger, cleaning the inlet screen, checking combustion settings, and running a full diagnostic. In areas with harder water, descaling every 6 months may be necessary. Our Monterey service plan includes these visits at a discounted rate, priority scheduling, and software-based performance tracking. Regular maintenance extends unit life to 20 years or more—double that of most tank heaters.
