FAQs
What is a tankless water heater and how does it work?
A tankless water heater—also called an on-demand water heater—heats water only when you open a hot-water tap. Cold water flows through a heat exchanger that is warmed by either natural gas or electricity, delivering a continuous supply of hot water without the need for a storage tank. Because there is no standby tank, energy losses are substantially reduced and you never "run out" of hot water.
What advantages does a tankless unit offer Morristown homeowners compared to a traditional tank?
Key benefits include • Unlimited hot water: Perfect for large families or homes with high hot-water demand. • Energy savings: The U.S. DOE estimates 24–34 % greater efficiency for homes that use 41 gal/day or less, and 8–14 % for high-demand homes. • Space savings: Wall-mounted units free up floor space in Morristown’s often compact basements. • Longer service life: 20+ years for most quality units versus 8–12 for a storage tank. • Reduced risk of leaks and water damage because there’s no large reservoir of stored water.
What size or flow-rate (GPM) tankless heater do I need for my Morristown home?
Sizing is based on the total gallons per minute (GPM) you’ll need during peak demand and the required temperature rise. In Morristown, incoming cold-water temperature averages 45–50 °F in winter. If you want 120 °F water, you need a 70–75 °F temperature rise. Add up simultaneous fixture use—for example: shower (2.0 GPM) + dishwasher (1.5 GPM) + sink (1.0 GPM) = 4.5 GPM. You’d choose a unit rated to deliver at least 4.5 GPM at a 70 °F rise. Our technicians perform a detailed load calculation during your estimate to recommend the right model.
How long does installation take and what does it typically cost in Morristown?
A straightforward replacement of a gas storage tank with a gas tankless unit usually takes one day. More complex jobs—such as relocating the heater, upsizing gas lines, or upgrading venting—may extend into a second day. Costs in the Morristown area generally start around $3,200–$3,800 for mid-efficiency models and range up to $4,500–$5,800 for high-efficiency condensing units, including labor, permits, and removal of the old tank. We provide written, no-obligation quotes after an on-site assessment.
What kind of maintenance does a tankless water heater require?
Tankless systems need annual service to maintain efficiency and warranty coverage. The main task is descaling or flushing the heat exchanger with a vinegar or citric-acid solution to remove mineral buildup—especially important in Morristown where water hardness averages 14–17 grains per gallon. Our maintenance visit also includes cleaning the air intake filter, checking burner operation, and updating firmware (for smart models). Regular servicing extends the unit’s lifespan and keeps energy savings on track.
Are there rebates or incentives available for installing a tankless water heater in Morristown?
Yes. As of 2024, New Jersey’s Clean Energy Program offers up to a $700 rebate for qualifying ENERGY STAR® condensing tankless models with ≥0.95 UEF. Morristown-area gas utilities such as NJNG and Elizabethtown Gas provide additional rebates of $300–$500, and federal tax credits of 30 % (up to $600) may apply under the Inflation Reduction Act. Our team handles the paperwork and provides the required AHRI certificates to ensure you receive every eligible incentive.
