FAQs
What are the main advantages of choosing a high-efficiency tankless water heater for my Delano home?
A high-efficiency tankless unit heats water on demand, so you’re not paying to keep 40–50 gallons hot all day. This typically cuts water-heating energy use by 25-40 %. You also gain endless hot water, a space-saving wall-mounted design, and life spans of 20+ years—about twice that of a standard tank. Modern condensing models capture additional heat from exhaust gases, further boosting efficiency and lowering utility bills in Delano’s hot summers and mild winters.
How do I determine the correct size (flow rate) for my tankless water heater installation?
Sizing is based on simultaneous fixture use and required temperature rise. We calculate the gallons-per-minute (GPM) demand of showers, faucets, and appliances likely to run at the same time, then measure the temperature increase needed—from Delano’s typical 60 °F incoming water in winter to your desired 120 °F. For example, two showers (2.0 GPM each) and a dishwasher (1.5 GPM) running together need ~5.5 GPM with a 60 °F rise; we would recommend a unit rated 6-7 GPM at that rise to ensure uninterrupted hot water.
Will my existing gas or electrical service support a high-efficiency tankless system?
Most gas units require a ¾-inch gas supply line and up to 200 k Btu/hr input, higher than typical tank heaters. Electric models need 120–150 A of dedicated 240-V capacity. During our onsite evaluation, we check your gas meter capacity, line sizing, venting path, and electrical panel amperage. If upgrades are needed, we provide a clear cost estimate and handle all permitting with the City of Delano before installation.
What is involved in the installation process and how long will it take?
A standard replacement in Delano usually takes one working day. We drain and remove your old tank, mount the new tankless unit on an exterior or garage wall, run upgraded gas/electric lines, install stainless-steel or PVC condensing venting, add an isolation valve kit for maintenance, and flush the lines. Finally, we test for gas leaks, set the temperature, and register the warranty. Complex retrofits that require gas meter upsizing or long vent runs may take an additional day.
How much will a high-efficiency tankless water heater cost, and are there rebates available in Kern County?
Installed prices in Delano range from $3,200–$4,800 for most homes, depending on flow rate, venting length, and utility upgrades. Southern California Gas Company and PG&E periodically offer $200–$400 rebates on ENERGY STAR certified models. Federal tax credits under the Inflation Reduction Act can cover 30 % of the project cost up to $600. We handle all paperwork so you receive every available incentive.
What maintenance does a tankless unit require and how long will it last?
To maintain peak efficiency and protect the heat exchanger from Delano’s moderately hard water (8–10 grains per gallon), flush the unit with a vinegar or citric-acid solution once a year. This takes about an hour with the built-in isolation valves. Also clean the inlet filter quarterly and schedule a professional inspection every two years. With proper care, high-efficiency condensing tankless heaters last 20–25 years—double the typical tank life—making them an excellent long-term investment.
