Why Tankless
Tankless water heaters offer advantages that make them the preferred choice for many Middle Tennessee homeowners upgrading their hot water system.
If you’re currently using a traditional tank water heater and considering the switch, our team can evaluate your home’s hot water demand, assess your gas and venting infrastructure, and recommend the right tankless unit for your situation. Call (615) 290-9860 for a free consultation.
Longer Lifespan
Tankless units last 15 to 20 years — nearly twice as long as traditional tank water heaters. That's nearly double the service life from a single installation.
Energy Savings
Because tankless units heat water only when you turn on the tap, they don't spend energy keeping a tank of water hot 24 hours a day. Over years of use, that difference adds up on your utility bills.
Continuous Hot Water
A properly sized tankless unit never runs out. No more timing your shower around the dishwasher or waiting for the tank to recover.
Smaller Footprint
Tankless units mount on a wall and take up a fraction of the floor space a 50 or 80 gallon tank occupies. For homes in La Vergne and Nashville where utility space is tight, this matters.
Signs It's Time
What to Watch For
Tankless units are designed to last 15 to 20 years. If yours is in that range, efficiency has likely declined even if the unit still runs. Replacing before failure lets you choose your timing and budget.
One repair call is normal. Two in a year is a pattern. If you're calling for service regularly, the cost of repeated repairs starts to approach the cost of a new installation. A new unit resets the clock on performance and reliability.
If energy bills are climbing or the unit takes longer to reach temperature than it used to, internal wear is likely the cause. Mineral scale, aging components, and reduced combustion efficiency all contribute.
Struggling to deliver hot water when multiple fixtures run at the same time is a sign the unit is no longer performing to spec — either through wear or because it was undersized from the start.
Persistent error codes that return after repair indicate internal components are failing. At some point, the diagnostic cost alone exceeds the value of keeping the unit running.

Sizing Matters
Tankless water heaters are rated by flow rate (gallons per minute) and temperature rise. The colder the water coming into your home, the harder the unit works to heat it, and the lower its effective flow rate.
In Middle Tennessee, incoming ground water temperature is around 55 degrees Fahrenheit — significantly colder than what homes in Florida or Texas receive. A unit rated at 8 gallons per minute in a warm climate may only deliver 5 gallons per minute here during winter months.
This is why sizing matters, and why it needs to be done by someone who understands local conditions. Gold Star sizes every tankless installation for Middle Tennessee water temperatures, household fixture count, and peak demand patterns. We don’t install a unit that looks good on paper but underperforms in January.
Tankless units are measured in gallons per minute. The GPM you need depends on how many fixtures run simultaneously at peak demand in your home.
Tennessee incoming water temperature runs around 55°F — significantly colder than Southern states. This directly reduces a unit's effective output during winter months.
A unit rated at 8 GPM in warm-climate testing may only deliver 5 GPM in a Nashville January. An undersized unit means lukewarm water when multiple fixtures run at once.

The existing tankless unit is safely disconnected from gas, water, and electrical systems and removed from your La Vergne or Nashville home.
We inspect the gas supply line to determine whether an upgrade is needed. Switching from tank to tankless, or upgrading to a higher-capacity unit, often requires a larger gas supply line.
We inspect existing venting and upgrade to stainless steel venting if required by the new unit's specifications. Proper venting is critical for safety and performance.
The new unit is wall-mounted and connected to gas, water, and electrical systems. Temperature output is set and all connections are verified before testing.
We verify temperature output at normal demand, check every connection for leaks, and confirm venting draws properly. We walk you through operation before we leave.
Transparent Pricing
Gold Star’s commitment: We provide a detailed written estimate that breaks down every line item before we start. You see exactly what you’re paying for, and nothing is added without your approval. No surprises on the invoice.
