Why Upgrade

The Modern Way to Heat Water

Tankless systems represent the future of residential and commercial water heating, combining cutting-edge efficiency with unmatched convenience.

Lower Energy Bills

No standby heat loss. Tankless units only consume gas when you actually use hot water, reducing your monthly utility costs by up to 30%.

Unlimited Hot Water

Never run out of hot water. Multiple showers, laundry, and dishes happening at once? No problem. Your supply is truly endless.

Space-Saving Design

Mount on a wall, indoors or outdoors. Tankless units are compact and require a fraction of the space a traditional tank heater needs.

Lower Carbon Footprint

Using significantly less energy means a smaller environmental impact. Upgrade to a sustainable heating solution for your home.

Minimal Maintenance

Professional flushes once annually keep your system running at peak efficiency. No tank corrosion, no sediment buildup issues.

Long Lifespan

With proper maintenance, tankless units last 15-20+ years, significantly longer than traditional tanks that typically last 10 years.

Ownership & Care

Keep Your System Running Strong

Regular professional maintenance ensures your tankless system delivers peak performance and longevity. AEI ProGas provides comprehensive care to protect your investment.
  • Annual Professional Flush: We circulate descaling solution through the heat exchanger to remove mineral buildup and maintain efficiency.
  • Filter & Screen Inspection: Clean or replace inlet filters to ensure unobstructed water flow.
  • Gas & Venting Check: Verify all gas connections, venting, and combustion safety.
  • Gas & Venting Check: Verify all gas connections, venting, and combustion safety.
  • Temperature Calibration: Fine-tune your system to deliver consistent, safe water temperatures.

⚠ Hard Water Areas

If you live in an area with hard water (high mineral content), annual flushing is critical. Scale buildup can significantly reduce efficiency and component lifespan.

Warning Signs of Trouble

  • Inconsistent water temperature (sudden cold bursts)
  • Reduced water pressure or flow rate
  • Unusual noises (rumbling, popping, whining)
  • Discolored or rusty-looking water
  • Error codes on the digital display
  • Unit is over 15 years old and requires frequent repairs

How does a gas tankless water heater save money compared to a traditional tank?

Traditional water heaters experience “standby heat loss” because they must constantly use energy to keep a large tank of water hot, 24/7. Gas tankless water heaters only ignite and consume gas when you actually turn on a hot water tap. This on-demand operation can reduce water heating energy costs by up to 30% or more annually.

A flush is a vital maintenance procedure where a professional circulates a descaling solution (often food-grade white vinegar) through the heat exchanger to remove calcium and magnesium buildup. Because water is flash-heated in a tankless unit, scale accumulates quickly, especially in areas with hard water. We recommend a professional flush at least once a year to maintain efficiency and prevent premature component failure.
Absolutely, provided the unit is properly sized. Tankless heaters are rated by their flow rate (Gallons Per Minute or GPM) and the temperature rise they can achieve. Our experts at AEI ProGas will calculate your peak hot water demand such as running two showers and a washing machine simultaneously to recommend and install a unit with the exact capacity your household requires.
Gas tankless units require specialized venting to safely exhaust combustion gases outdoors. Unlike traditional atmospheric vents, most modern tankless heaters use direct-vent systems with concentric pipes (a pipe within a pipe) that bring in fresh combustion air from the outside while exhausting the exhaust gases. Our licensed technicians ensure all venting is installed safely and complies with local codes.
Converting from electric to gas requires installing a new, properly sized gas line to the location of the new heater, as well as installing the necessary venting. While it is a more involved process than a simple swap, our experienced team handles the entire retrofitting process seamlessly, ensuring your home is safely equipped for the upgrade.
