FAQs
How much can I save on energy bills by switching to a high-efficiency tankless water heater in Harriman?
Most homeowners in Harriman see energy-cost reductions of 20-40 % after upgrading to a high-efficiency tankless unit. Unlike traditional tanks that keep 40–50 gallons hot 24/7, a tankless heater only fires when you open a tap, eliminating standby losses and lowering both gas and electric consumption year-round.
Will a tankless water heater provide enough hot water for my entire family?
Yes. We size your unit based on simultaneous demand—showers, laundry, dishwasher, etc.—using your home’s peak flow rate (measured in gallons per minute). For a typical Harriman household of 3–5 people, a 7–9 GPM high-efficiency model supplies endless hot water even during back-to-back showers.
What is involved in the installation process for Harriman homes?
Our licensed plumbers handle everything: load calculation, Orange County permit filing, removal of the old tank, gas line and vent upgrades, condensate drain, and mounting the compact wall-hung unit. Most projects take a single day, and we schedule inspections with the local building department for you.
Are there rebates or incentives available locally?
Yes. New York State’s Clean Heat program offers up to $1,000 for qualifying high-efficiency natural-gas tankless heaters, and utilities such as Orange & Rockland often add $200–$400 instant rebates. Federal tax credits of 30 %, capped at $600, are also available under the Inflation Reduction Act when the unit’s UEF ≥ 0.95.
How do I maintain a high-efficiency tankless system to ensure longevity?
Annual maintenance keeps your warranty valid and the heat exchanger scale-free. We flush the unit with food-grade vinegar, inspect the burner, clean the inlet filter, and check venting integrity. With proper care, today’s stainless-steel heat exchangers routinely last 20+ years.
What warranty and service support do you provide in Harriman?
We register every unit for a 15-year heat-exchanger warranty, 5 years on parts, and 1 year on our labor. Because we’re local, our 24/7 emergency line dispatches a certified technician within hours if you ever lose hot water, ensuring peace of mind long after installation.
