FAQs
What advantages does a tankless water heater offer Monteagle homeowners compared with a traditional tank?
Tankless units heat water only when you open a tap, eliminating standby heat loss and typically cutting water-heating costs 20–40 %. Because there is no storage tank, they never "run out" of hot water, the compact wall-hung design frees up floor space, and their average life expectancy (20+ years) is roughly double that of a tank. In Monteagle’s humid climate, the sealed combustion design also reduces the risk of condensation or rusting that can shorten the life of a conventional tank.
How does Peak Efficiency Plumbing determine the right-sized tankless model for my household?
During our free on-site assessment we measure the home’s incoming water temperature, count hot-water fixtures and appliances, and discuss your peak-use habits (showers, laundry, dishwasher, etc.). We then calculate gallons-per-minute (GPM) demand and select a unit that can raise Monteagle’s winter inlet water (≈ 50 °F) to 120 °F at that flow rate. Proper sizing ensures you always get simultaneous hot water without overspending on an oversized heater.
Will a tankless water heater perform well during Monteagle’s colder winter months?
Yes. Modern gas and electric tankless units automatically modulate their burners or heating elements to maintain set temperature even when inlet water is colder. We choose models rated for at least a 70 °F rise at your required flow rate. For homes with extremely high winter demand we can install parallel units or a recirculation loop so you still receive endless hot water instantly.
What is the installation process and how long will it take?
Most residential replacements are completed in one day. We start by safely draining and removing your old tank, upgrade gas or electrical service if needed, install stainless-steel venting, mount the new tankless unit, connect water/gas/electric lines, and program the controller. Before we leave, we test for leaks, confirm proper combustion, dispose of the old tank, and walk you through operating and maintenance steps.
What routine maintenance does my new tankless system need?
To maintain peak efficiency and protect the heat exchanger from mineral buildup common in Monteagle’s hard water, we recommend a yearly 45-minute descaling flush using food-grade vinegar. We include the first annual service at no charge and can set up an affordable maintenance plan thereafter. Cleaning the inlet screen filter and checking venting for debris once or twice a year is usually all that’s required.
Are there rebates or tax incentives available for tankless water heaters in Tennessee?
Yes. Tennessee Valley Authority (TVA) occasionally offers rebates for ENERGY STAR® natural-gas tankless installations, and qualifying homeowners can claim a 30 % federal tax credit (up to $600) under the Inflation Reduction Act. We provide the model’s AHRI certificate and completion paperwork, and can help you submit the rebate and tax forms to maximize your savings.
