FAQs
What is “standby energy loss” in a traditional water heater, and how does a tankless unit eliminate it?
Standby energy loss is the heat that escapes from a storage-type water heater’s tank while the water sits unused. To keep the tank at the set temperature, the burner or heating element cycles on and off all day, wasting gas or electricity. A tankless (on-demand) heater has no storage tank; it heats water only when a hot-water tap opens, so there is virtually no standby heat to lose and no energy consumed maintaining a reservoir of hot water.
Why is a tankless water heater well-suited to Monterey’s coastal climate?
Monterey’s moderate temperatures mean incoming water is rarely near-freezing, so a tankless unit doesn’t have to work as hard to raise the water to a comfortable temperature, improving efficiency. The mild climate also reduces corrosion stress on outdoor or garage-mounted units, extending service life. Finally, many Monterey homes have limited indoor space; the compact, wall-hung design of a tankless heater frees up floor area that a bulky 40- or 50-gallon tank would otherwise occupy.
How much can I expect to save on energy bills by switching from a tank to a tankless water heater?
Savings depend on hot-water usage patterns, fuel type, and the efficiency of your old tank. For an average Monterey household of four using natural gas, ENERGY STAR® studies show tankless units can cut water-heating costs by 25–40%, translating to roughly $90–$180 per year. Electric tankless models often save 10–15% compared with standard electric tanks. Over a 15-year lifespan, cumulative savings can exceed $1,500 and help offset the higher upfront cost.
What size and type of tankless water heater do I need for my Monterey home?
Sizing is based on simultaneous hot-water demand, measured in gallons per minute (GPM), and required temperature rise. In Monterey, municipal supply temperature averages 55–60°F, so achieving a 120°F set-point requires a 60–65°F rise. Add the flow rates of fixtures you may use at once (e.g., shower 2.0 GPM + kitchen sink 1.5 GPM = 3.5 GPM). Most families choose a 6–8 GPM gas unit for whole-house use. Smaller electric models (2–4 GPM) are ideal for point-of-use applications such as a remote bathroom. During our site visit we calculate exact demand, evaluate gas line capacity or electrical service, and recommend the right model and venting configuration.
How long does installation take and what should I expect during the process?
A typical replacement of a tank with a wall-mounted gas tankless unit takes one full working day. Steps include: (1) draining and removing the old tank; (2) upgrading gas piping to the larger flow rate most tankless units require; (3) running a new category-III/IV stainless or PVC vent through the wall or roof; (4) installing water isolation valves, a sediment filter, and thermal expansion relief; (5) connecting the condensate drain (for high-efficiency units); and (6) commissioning the heater and setting the desired temperature. Minor drywall repair or patching around vent penetrations may be needed. Electric point-of-use units usually take 2–4 hours if adequate amperage is available.
Are there rebates or incentives in Monterey or California for installing an efficient tankless water heater?
Yes. As of 2024, Pacific Gas & Electric (PG&E) offers $300–$600 for qualifying ENERGY STAR condensing gas tankless units. Monterey Bay Community Power customers may receive an additional $200 credit. California’s TECH Clean California program sometimes provides stackable incentives, especially when you replace an electric resistance tank with a high-efficiency heat-pump or heat-pump–assisted tankless model. Federal tax credits under the Inflation Reduction Act cover 30% of project cost, up to $600, for ENERGY STAR natural-gas tankless heaters with ≥0.95 UEF. We assist clients with all paperwork to ensure they capture every available rebate and credit.
