FAQs
How much can I expect to save on energy bills with a tankless water heater in Petros?
Because a tankless unit only heats water when you turn on a tap, it eliminates the standby losses of a storage tank. For an average Petros household that currently uses a standard 40- or 50-gallon electric tank, energy studies show yearly savings of 24 – 40 %, or roughly $80–$150 in electricity costs. Gas tankless models typically deliver 15 – 30 % savings versus a gas storage heater. Actual results vary with hot-water usage patterns, fuel type, and incoming water temperature, but most customers see the system pay for itself in 5–8 years through lower utility bills.
What size tankless water heater do I need for my Petros home?
We size a tankless unit by the maximum gallons-per-minute (GPM) demand and the temperature rise needed. In Petros the groundwater temperature averages about 55 °F, so to get 120 °F hot water we need a 65 °F rise. A three-bedroom, two-bath home that may run a shower (2.5 GPM) and a washing machine (2.0 GPM) simultaneously should choose a unit that can deliver at least 6–7 GPM at that rise. Larger households or those with luxurious fixtures (body sprays, soaking tubs) may need 9 – 11 GPM or even two units installed in parallel. Our technician will calculate your exact demand during a free in-home assessment.
How long does installation take and will my water service be disrupted?
A straight swap from a tank to a tankless water heater typically takes 4–6 hours. If we need to upsize a gas line, add a 120-V outlet, or install new venting, the job can extend to a full working day. Your water supply is usually off for 1–2 hours while we connect the new unit. We coordinate with you beforehand to minimize downtime and make sure you have cold water access if needed. After installation we test every fixture, haul away the old tank, and leave the workspace clean.
Are there rebates or incentives available in Tennessee for installing a high-efficiency tankless heater?
Yes. Through 2032, the federal Energy Efficient Home Improvement Credit allows you to claim 30 % of the installed cost of a qualifying ENERGY STAR® gas or electric tankless water heater, up to $600. Many TVA-served electric utilities, including those in Morgan County, offer additional rebates of $200–$300 for switching from a resistance tank to a heat-pump or gas tankless model. We stay current on all local programs, prepare the paperwork, and provide the model and efficiency documentation you need for your rebate or tax credit claim.
Do tankless water heaters require special maintenance?
Maintenance is simple but important to keep efficiency high and maintain the manufacturer’s warranty. In Petros’ moderately hard water, we recommend an annual descaling flush with white vinegar or a food-grade solution to remove mineral buildup from the heat exchanger. The procedure takes about 45 minutes and can be done by the homeowner or by our service team. In addition, clean the inlet screen filter twice a year and check the pressure-relief valve. Gas units should have their combustion chamber inspected and venting checked for blockages every two years.
Can a tankless water heater supply enough hot water for multiple fixtures at once?
Absolutely—provided the unit is correctly sized. Modern condensing gas models can deliver more than 11 GPM, enough for two showers and a dishwasher simultaneously. If your peak demand is higher, we can install units in parallel or design a hybrid system with a small buffer tank and a recirculation loop to eliminate wait times at distant faucets. Our sizing assessment factors in your family’s habits and fixture flow rates so you never run out of hot water.
