FAQs
How does a tankless water heater improve energy efficiency compared to a traditional tank unit?
A tankless water heater heats water on demand instead of maintaining a large reservoir of hot water. This eliminates standby heat loss, lowering energy consumption by 24–34% for homes that use up to 41 gallons of hot water daily. In Decherd’s moderate climate, this can translate to noticeable reductions in monthly utility bills and a smaller carbon footprint.
What size tankless water heater do I need for my Decherd home?
Sizing is based on your household’s simultaneous hot-water demand and the temperature rise required. We calculate the flow rates (gallons per minute) of fixtures you expect to run together—such as a shower and washing machine—then factor in Decherd’s average incoming water temperature (about 55–60 °F). Most three-bedroom homes require a unit capable of 7–9 GPM, but we’ll perform a detailed load calculation during the consultation to recommend the right model.
Will I need to upgrade my gas or electrical service for a tankless installation?
Possibly. Gas-fired units need a larger gas line (¾" is common) and Category III or IV venting. Electric units often require 240-volt service with multiple 40- to 50-amp breakers. During our site visit, we inspect your current utilities and provide a clear estimate if upgrades are needed, ensuring the system meets Tennessee code and operates safely.
How long does the installation process take?
A standard replacement—removing the old tank and installing a new gas or electric tankless heater—usually takes 4–8 hours. If utility upgrades or vent re-routing are necessary, the job may extend to a full day. We schedule installations to minimize downtime, so you can expect hot water the same day in most Decherd homes.
What maintenance is required to keep a tankless water heater running efficiently?
Annual maintenance is recommended: flush the heat exchanger with a vinegar solution to remove mineral scale, inspect the venting, clean the inlet screen filter, and check burner or element performance. Decherd’s water has moderate hardness, so descaling once a year maximizes efficiency and preserves the manufacturer’s warranty.
What kind of cost savings can I expect, and are there local incentives?
Homeowners typically save $80–$120 per year on energy bills, depending on usage. Over the 20-year lifespan of a tankless unit, this can offset the higher upfront cost. Tennessee offers periodic rebates through TVA’s EnergyRight program, and many utility companies provide bill credits for high-efficiency upgrades. We’ll help you identify current incentives and handle the paperwork to maximize your savings.
