FAQs
What are the main benefits of choosing a high-efficiency tankless water heater for my Morristown home?
High-efficiency tankless units heat water only when you need it, eliminating standby losses common with storage tanks. This can cut water-heating energy use by 25–40%, provide an endless supply of hot water, free up floor space, and typically last 20+ years—almost twice the lifespan of a conventional tank heater.
How long does a professional tankless water heater installation typically take?
Most residential installations in Morristown are completed in one working day. The timeline includes removing the old tank, upgrading venting or gas lines if needed, mounting the new unit, performing system flushes, and completing code inspections. Larger homes with multiple units or complex retrofits may require two days.
Will my existing gas line and venting work with a new high-efficiency unit?
Often, tankless models—especially ultra-high-efficiency condensing types—require a larger gas supply line (3⁄4" instead of 1⁄2") and dedicated Category III or PVC venting. During our free in-home assessment, we inspect your gas capacity and flue route, then provide a written quote that includes any necessary upgrades to meet New Jersey plumbing and mechanical codes.
What maintenance does a tankless water heater require?
Annual or bi-annual maintenance is recommended. We flush the heat exchanger with food-grade vinegar to remove mineral scale, clean the inlet screen filter, inspect the condensate trap, and test safety sensors. Regular servicing preserves efficiency, prevents lime buildup, and keeps most manufacturers’ warranties valid.
Are rebates or incentives available in Morristown for high-efficiency tankless installations?
Yes. Through New Jersey’s Clean Energy Program, qualifying ENERGY STAR® condensing tankless heaters can earn rebates—currently up to $700. Morristown residents may also be eligible for federal tax credits of 30% of project cost (capped at $600 for water heaters) under the Inflation Reduction Act. We handle all paperwork and provide documentation for your filing.
How do I know what size (flow rate) tankless water heater I need?
Sizing is based on simultaneous demand, measured in gallons per minute (GPM), and required temperature rise. We calculate the peak load—such as one shower (2.5 GPM) plus a dishwasher (1.5 GPM)—then match it to models delivering that flow at Morristown’s average winter groundwater temperature of about 50 °F. Proper sizing ensures you’ll never run out of hot water, even on the coldest day.
