Nothing ruins a morning routine faster than a shower turning ice-cold halfway through. If you are tired of scheduling your family’s showers or waiting endlessly for a tank to refill, it is time to upgrade the way your home heats water. At Cornwell Plumbing, we provide expert Tankless
Water Heater Installation in Pittsboro, delivering a modern solution that ensures the hot water flows as long as you need it.
Switching to a tankless system is a smart investment in your home’s efficiency and your family’s comfort. Unlike traditional bulky tanks that constantly reheat a limited supply of water, a tankless unit heats water instantly on demand. This eliminates standby energy loss and ensures you are never left shivering because the "hot water ran out."
Why Make the Switch to On-Demand Water Heating?
Moving away from standard tank-style heaters offers distinct advantages for modern households. Many Pittsboro residents are finding that energy-efficient water heating transforms their daily routines while freeing up valuable space in their homes.
Here are the key benefits of upgrading your hot water system:
- Endless Hot Water Supply: Whether you are running the dishwasher, washing clothes, or taking a long bath, the water is heated instantly as it flows through the unit. You are not limited by the gallon capacity of a tank.
- Space-Saving Efficiency: Traditional tanks dominate utility closets or basements. A gas tankless water heater is roughly the size of a suitcase and mounts on the wall, allowing you to reclaim square footage for storage or other uses.
- Cleaner Water: Storage tanks can accumulate rust and sediment at the bottom over years of use. Tankless systems heat fresh water as it passes through, reducing the chance of rust mingling with your bathing water.
- Longevity: While traditional tanks often require replacement every 10–12 years, a properly maintained tankless unit can last up to 20 years.
The Installation Process: A Step-by-Step Guide
At Cornwell Plumbing, we believe in doing the job right the first time. Tankless Water Heater Installation requires precise plumbing and electrical work to ensure safety and optimal performance.

- System Upgrades: We upgrade gas lines or electrical circuits if necessary to support the high-power demand of instantaneous heating.
- Mounting and Venting: The new unit is secured to the wall, and specialized intake/exhaust venting is installed to ensure safe operation.
- Calibration: We test the temperature output and flow rates to ensure everything is balanced before we leave.
Do Tankless Water Heaters Work Well in Indiana Winters?
A frequent question we receive is whether this technology can handle the freezing temperatures of a Pittsboro winter. The answer is yes, but proper sizing is critical.
In winter, the groundwater entering your home is significantly colder (often near freezing) compared to summer. The heater must work harder to raise that water to a comfortable 120°F. If a unit is undersized, it may struggle to reach the desired temperature during January and February.
We calculate the specific "temperature rise" needed for our local climate. By installing a unit with a high BTU rating, we ensure your shower stays hot even when the ground outside is frozen. We also insulate external pipes to prevent freezing during extreme cold snaps.
Can I Replace My Existing Tank Water Heater with a Tankless One in the Same Spot?
You can certainly replace an old tank with a tankless model, but it is rarely a simple "swap." The location might stay the same, but the infrastructure usually changes.
- Venting Differences: Standard tanks often use atmospheric vents (chimneys). Tankless units typically require dedicated PVC venting that goes out the side of the house to handle the exhaust.
- Gas Line Capacity: To heat water instantly, gas tankless water heaters need a larger volume of gas at once. We often need to upsize the gas piping connecting to the unit, even if the location is the same.
- Water Line Re-routing: Since the connections on a tankless unit are at the bottom (and the unit is on the wall), we will modify your water lines to connect properly.
Do Tankless Water Heaters Run Out of Hot Water?
Technically, a tankless unit does not "run out" because it creates hot water on the spot. However, it can be "overwhelmed."
Every unit has a maximum flow rate, measured in Gallons Per Minute (GPM). If you try to run two showers, the dishwasher, and the washing machine all at the exact same time, you might exceed that flow rate. The system will either reduce the water pressure or the temperature will drop slightly.
We help you avoid this by calculating your "peak demand"—the maximum amount of hot water your family uses at one specific time—and sizing the unit to match that need.

Frequently Asked Questions
Even gas-powered tankless units require electricity to operate their control boards, sensors, and ignition systems. If your home loses power during a storm, you will not have hot water unless you have a battery backup or a whole-home generator.
Yes, Indiana’s hard water can lead to mineral scale buildup on the heat exchanger. This doesn't mean you can't have one, but it does mean tankless water heater maintenance is vital. We recommend flushing the system with a vinegar solution once a year to keep it efficient.
Yes, there is a slight delay. Because the unit is often mounted on a wall and not storing pre-heated water, it takes a few seconds to ignite and heat the water, plus the time it takes for water to travel through the pipes to your faucet. This is usually only a few seconds longer than a standard tank.
They are actually safer in many regards. Tankless units allow you to set a precise maximum temperature on a digital controller, significantly reducing the risk of accidental scalding compared to inconsistent tank temperatures.
