FAQs
What are the main benefits of switching to a tankless water heater in the Philadelphia area?
Tankless (on-demand) water heaters heat water only when you open a tap, eliminating the standby losses of a storage tank. In Philadelphia’s four-season climate this translates into energy savings of 25–40 % a year, endless hot-water supply for large families, and recovery of up to 16 sq ft of floor space—ideal for row homes and tight basements. A quality tankless unit also lasts 20+ years (roughly twice the life of a conventional tank) and offers advanced freeze-protection and scale-reduction features that help it cope with our cold winters and moderately hard city water.
How long does a professional tankless water heater installation take and will my water be shut off all day?
Most residential installations are completed in a single workday (4–8 hours). Your water service is normally off for just 1–2 hours while we disconnect the old tank and tie the new unit into the gas, water, condensate, and venting lines. Our master plumbers arrive with all permits in hand, protect the work area, haul away the old heater for recycling, pressure-test new connections, and purge air from the water and gas lines before relighting your appliances. We’ll also give you a short tutorial on operating the new digital controller before we leave.
Will I need to upgrade my gas line or electrical panel for a tankless unit?
It depends on the model chosen. Most whole-house gas tankless heaters need a dedicated ¾-in gas line capable of supplying 150–199 k Btu/h. In many Philadelphia homes the existing ½-in line is adequate only for a 40- or 50-gallon tank, so upsizing is common; we size and install the new line to current International Fuel Gas Code and secure all city permits. Electric tankless models require 120–150 A of dedicated breaker capacity and #6–#4 copper wiring, which usually means a 200-amp service upgrade. During your free estimate our licensed plumbers perform a load calculation and let you know exactly what, if any, upgrades are needed.
Are there rebates or tax incentives for installing an energy-efficient tankless water heater in Philadelphia?
Yes. PECO currently offers a $300 rebate on qualifying ENERGY STAR® natural-gas tankless units. PGW’s EnergySense program periodically adds additional incentives for high-efficiency equipment. On the federal level, the Energy Efficient Home Improvement Credit lets homeowners claim 30 % of project cost, up to $600, for a high-efficiency gas tankless heater installed through 2032. Our office prepares all rebate forms, registers your unit with the manufacturer, and provides the documentation you’ll need for your tax preparer.
How much maintenance does a tankless water heater need, and can Master Plumbers handle it for me?
A tankless heater should be descaled (flushed) once a year with food-grade vinegar or citric acid to remove mineral buildup, especially important because Philadelphia’s water hardness averages 7–9 grains per gallon. The inlet screen filter should be cleaned every 6–12 months, and the condensate neutralizer media replaced every 2–3 years. Our Master Plumbers Maintenance Plan includes an annual flush, full diagnostic, gas-pressure check, and software update, keeping your warranty valid and extending the life of the unit.
What is the typical cost of a tankless water heater installation in Philadelphia and what affects the price?
Including the heater, vent kit, isolation valves, permits, and professional labor, most homes fall between $3,200 and $5,500. Variables include: the heater’s size and brand, gas vs. electric fuel type, need for gas-line or electrical upgrades, venting length and roof or side-wall termination, addition of a recirculation pump, condensate pump, accessibility of the install location, and any code-required chimney liner if you’re also retiring an atmospheric furnace.
