FAQs
What advantages does a tankless water heater offer over a traditional storage-tank unit?
Tankless (on-demand) units heat water only when you open a tap, which eliminates stand-by heat loss and can cut energy use by 20–40 %. They take up far less space, supply endless hot water as long as the unit is properly sized, last around 20 years (about twice a tank heater’s life span), and reduce the risk of tank leaks or ruptures. Because Delano’s mild climate keeps incoming water temperatures moderate, tankless heaters run even more efficiently here.
Will a single tankless water heater provide enough hot water for my whole household in Delano?
Yes—when it’s correctly sized. We calculate required flow rate (gallons per minute) by adding the demand of appliances you may run at the same time—shower, dishwasher, washing machine, etc.—and factoring in Delano’s average winter groundwater temperature of roughly 55–60 °F. Most three-to-four-bathroom homes need a 9–11 GPM gas unit or two smaller electric units in parallel. During your estimate, we measure usage patterns to recommend the right model so you never run out of hot water.
How long does installation take, and will my water be shut off?
A straightforward replacement of a tank heater with a gas tankless model usually takes 4–6 hours. Converting from electric to gas, relocating the unit, or adding larger gas and vent lines can extend the job to one full day. Your water will be off only during the final tie-in—typically 1–2 hours. We schedule work around your routine and always leave one bathroom operational whenever possible.
What up-front costs should I expect, and are there incentives for Delano homeowners?
Installed prices typically range from $2,200–$3,500 for a mid-efficiency gas unit and $3,000–$4,500 for a high-efficiency condensing model, including labor, venting, and any required gas line upgrades. California’s TECH Clean California program may offer $300–$1,000 rebates, and SoCalGas frequently provides additional incentives. If you switch from an electric tank to a high-efficiency gas condensing unit, you may also qualify for federal tax credits of up to 30 % (max $600) under the Inflation Reduction Act.
What maintenance does a tankless water heater need in Kern County’s hard-water region?
To keep mineral buildup from reducing efficiency, we recommend a professional descaling and filter cleaning once a year (twice if you’re on a private well). The process takes about an hour and involves circulating a vinegar solution through the heat exchanger. We offer affordable annual service plans that include flushing, combustion check, and firmware updates. With routine care, your unit can maintain 95 %+ efficiency for its entire 20-year life.
Do you handle permits, code compliance, and warranty registration?
Absolutely. Delano and Kern County require permits for gas line modifications and venting changes. We pull all necessary permits, schedule inspections, and ensure the installation meets California Plumbing and Mechanical Codes. After the job, we register your tankless heater with the manufacturer so your 5- to 15-year heat-exchanger warranty—and our labor warranty—are fully in effect.
