FAQs
What advantages does a tankless water heater offer over a traditional storage-tank unit in Harriman?
A tankless heater produces hot water only when you open a tap, eliminating standby heat loss that occurs with storage tanks. This can cut water-heating energy use by 25–40 %. Because there is no bulky tank, you gain floor space and remove the risk of catastrophic tank leaks. Tankless units also deliver an uninterrupted stream of hot water—as long as the unit is properly sized—so families in Harriman never run out during back-to-back showers or laundry cycles.
How does a tankless system deliver “endless” hot water?
Inside the unit, a high-output gas burner or electric heating element sits beside a heat exchanger. When you open a hot-water fixture, flow sensors signal the burner/element to ignite instantly. Cold water passes through the heat exchanger, absorbs heat, and exits the unit at the set temperature—continuously, for as long as water keeps flowing. Because water is heated on demand instead of being stored, there is no depletion of a limited tank supply, creating the perception of "endless" hot water.
What size tankless water heater do I need for my Harriman home?
Sizing is based on two factors: 1) maximum hot-water flow rate you expect to use at one time (gallons per minute, or GPM), and 2) the temperature rise required (difference between incoming cold-water temperature and desired hot-water set point). In Harriman, incoming winter water temperature averages around 50 °F. If you want 120 °F water, you need a 70 °F rise. Most households require 6–10 GPM to run two showers and a dishwasher simultaneously. Our technicians perform a fixture-by-fixture calculation on site to select the right model, ensuring you never exceed the unit’s capacity.
Will a tankless heater really lower my energy bills?
In many cases, yes. Tankless gas units achieve efficiencies of 90 %+ (condensing models) and avoid the constant reheating that tanks perform to keep water hot 24/7. Homeowners switching from an older atmospheric-vent tank in Harriman typically see water-heating utility savings of $80–$150 per year. Electric tankless units avoid standby loss entirely, though savings depend on local electric rates. Over a 15- to 20-year service life, these savings often offset the higher upfront cost.
What is involved in the installation and how long does it take?
A typical retrofit takes one day. We start by shutting off water, gas/electric, and safely removing the old tank. The tankless unit mounts to the wall, freeing up floor space. We then: 1) size and run new gas line or upgrade wiring if needed, 2) install stainless steel or PVC venting for gas models, 3) connect cold/hot water lines with isolation valves for future maintenance, 4) program the digital controller and test for leaks and proper combustion. Our Harriman installers pull any required city permits and arrange inspections to ensure code compliance.
What maintenance and lifespan can I expect from a tankless water heater?
Tankless systems typically last 18–20 years—roughly twice that of a storage tank—as long as basic maintenance is performed. In Harriman’s moderately hard water, we recommend an annual or bi-annual flush with white vinegar or a manufacturer-approved descaler to dissolve mineral buildup in the heat exchanger. The inlet water screen should be cleaned at the same interval. Gas units should also have a yearly combustion check to verify safe, efficient operation. Following these steps preserves efficiency, maintains the warranty, and helps the unit reach its full life expectancy.
