FAQs
How does a tankless water heater deliver “endless” hot water compared with a traditional storage tank?
A tankless unit heats water on demand as it flows through a high-efficiency heat exchanger. Because it doesn’t rely on a limited-capacity storage tank, it continues heating incoming cold water for as long as a hot-water tap is open. With the right-sized model and proper gas or electric supply, you’ll never “run out” the way you can with a 40–50-gallon tank that must reheat after depletion.
What are the main advantages of installing a tankless system in Monterey?
• Unlimited hot water whenever you need it. • Up to 30 % lower energy use because there’s no standby heat loss from a tank. • Compact wall-mounted design frees floor space—valuable in Monterey’s smaller coastal homes. • Longer service life (20+ years vs. 10-15 for tanks) and replaceable parts that reduce landfill waste. • Eligible for California rebates and the federal 25C tax credit when installed by a licensed contractor.
Do I need a permit for a tankless water heater in the City of Monterey, and what does the installation involve?
Yes. The Monterey Building Division requires a plumbing/mechanical permit for any water-heater replacement. Our team handles the paperwork and schedules the final inspection. Installation typically includes: 1. Sizing the unit based on your peak hot-water demand (gallons per minute). 2. Running a larger gas line (or upgrading electrical service) if needed. 3. Mounting the heater on an exterior or garage wall. 4. Installing stainless-steel venting or direct-vent concentric piping per California Mechanical Code. 5. Adding a condensate drain, seismic strapping, and PRV as required. Most projects are completed in one day once utilities and vent paths are confirmed.
How do I determine the correct size (flow rate) for my household?
Count the fixtures you might run at once—e.g., one shower (2.0 gpm) + kitchen sink (1.5 gpm) = 3.5 gpm. Add a 15 % buffer and check the incoming water temperature (usually 55 °F on the Monterey Peninsula). We match this demand and temperature rise to a unit’s rated gallons-per-minute at a 70 °F rise. For many three-bedroom Monterey homes, a 7–9 gpm gas unit or a whole-home 27 kW electric model is ideal. Our technician will perform the calculation during your free estimate.
What does a tankless installation cost in Monterey, and when will it pay for itself?
Installed prices range from $3,200–$4,900 for gas and $2,800–$4,200 for electric, including permit, venting, and any line upgrades. Annual energy savings typically run $80–$150 for gas and $60–$120 for electric, depending on hot-water usage. Combine those savings with available rebates (up to $600) and the longer service life and most homeowners see a 5–7-year payback compared with replacing a storage tank twice over the same period.
What maintenance is required, especially with Monterey’s coastal water conditions?
Tankless heaters need annual or bi-annual flushing with a vinegar solution to remove mineral scale, which is more prevalent in Monterey’s moderately hard water (9–12 grains). We install isolation valves to make flushing simple. In addition, the air intake screen should be cleaned every 6–12 months, and a professional inspection performed every two years to verify burner efficiency or heating-element condition. Following this schedule keeps the warranty valid and ensures maximum efficiency for decades.
