FAQs
Why should I choose a tankless water heater for my Jefferson City home?
Tankless units heat water on demand, which eliminates standby heat loss and can cut energy bills by up to 40%. They also provide an endless supply of hot water, free up floor space, and typically last 5–10 years longer than conventional tanks—an advantage in Jefferson City where utility costs and square footage both matter.
How long does a professional tankless water heater installation take?
A standard replacement (swapping an existing tank for a new tankless model) usually takes 4–6 hours. If your home needs new venting, gas line upsizing, or electrical upgrades, the project can extend to a full day. During our in-home assessment we give you a precise timeline so you know exactly what to expect.
Do I need to upgrade my gas or electrical service?
Often, yes. Gas-fired tankless models may require a larger gas line (¾" instead of ½") to ensure proper BTU flow. Electric tankless heaters typically need a 200-amp service with multiple dedicated breakers. Our technicians evaluate your current utilities and handle any necessary upgrades to meet both manufacturer specs and Jefferson City building codes.
Are permits required for a tankless water heater installation in Jefferson City?
Yes. The City of Jefferson requires a plumbing/mechanical permit and, if gas work is involved, a separate gas permit. We pull and close all required permits, coordinate inspections with local authorities, and provide you with completion paperwork for your records and home resale value.
How do I maintain a tankless water heater once it’s installed?
Plan on an annual flush with white vinegar or a manufacturer-approved descaling solution to remove mineral build-up from Jefferson City’s moderately hard water. Our service package includes filter checks, burner inspection, and software updates, ensuring peak efficiency and preserving your warranty coverage.
What kind of warranty and financing options are available?
Most leading brands offer 12- to 15-year heat exchanger warranties and 5-year parts warranties. We stand behind our labor with a 2-year workmanship guarantee. Flexible financing, including 0% APR for 12 months or low-interest plans up to 60 months, lets you enjoy on-demand hot water without straining your budget.
