We Bring Endless Hot Water to the Island

Life in Galveston moves at its own pace, but your hot water shouldn’t. Whether you’re rinsing off after a day at Stewart Beach, hosting guests at a vacation rental near The Strand, or maintaining a historic home in the East End, we are here to ensure you never run out of hot water.

At Hot Water Guys, we specialize in high-efficiency tankless solutions designed to withstand the unique coastal environment of Galveston Island. Our founders, Tom Massimin and Kenny Browning, have spent nearly two decades helping Texas homeowners transition to smarter, space-saving technology.

Why We Recommend Tankless for Your Galveston Home

We understand the challenges of island living, from limited square footage in historic cottages to the high hot water demands of large beach houses.

  • Unlimited Hot Water: We ensure you have a continuous supply for back-to-back showers and laundry—even during busy holiday weekends.
  • Corrosion Resistance: Coastal air is tough on appliances. We install high-quality units with durable heat exchangers that are built to last.
  • Space-Saving Design: We reclaim your space by mounting compact units on the wall, which is especially beneficial in smaller island homes.
  • Superior Efficiency: We help you stop paying to heat water 24/7. These systems only heat water on demand, which can be up to 34% more energy-efficient for many households.

2025 Financial Incentives for Galveston Residents

Upgrading to a high-efficiency system is a smart investment, and we help you claim every available incentive to lower your upfront costs.

Federal Tax Credits

Under the Inflation Reduction Act (Section 25C), Galveston homeowners can claim a federal tax credit of 30% of the project cost, capped at $600, for qualifying ENERGY STAR® tankless gas water heaters through December 31, 2025.

Local Rebates

While some utility programs vary by year, we stay updated on the latest offerings from providers like Texas Gas Service. If your home uses natural gas, you may be eligible for significant equipment rebates for installing high-efficiency units with a high Uniform Energy Factor (UEF).

Local Compliance: Permitting and Safety

We handle the technical details to ensure your installation is safe and legal. The City of Galveston requires a plumbing permit for water heater replacements to ensure they meet modern building and safety codes.

  • Professional Requirement: Most localities in Texas, including Galveston, require a Licensed Master Plumber to obtain the necessary permits and perform the work.
  • Inspections: Once we complete your installation, the city requires an inspection to verify that all gas connections, venting, and pressure relief systems are handled properly.
  • Historic Districts: If you live in a historic district like the Silk Stocking or Lost Bayou, we ensure your installation respects local preservation guidelines while providing modern performance.

FAQs: What Your Galveston Neighbors Ask Us

Can a tankless unit handle a large beach rental?

Yes. We specialize in sizing systems for high-occupancy homes. For very large rentals, we often link multiple units together to ensure that even if every shower is running at once, the water stays hot.

How does the salt air affect my unit?

Coastal environments can be corrosive. We recommend units with advanced protective coatings and offer regular maintenance to check for wear and tear, ensuring your system lasts its full 20- to 30-year lifespan.

How much can I save on my taxes in 2025?

If you install an ENERGY STAR® certified gas tankless model with a UEF of 0.95 or higher, you can claim a federal tax credit of up to $600.

Do I need to flush my unit every year?

Yes. To maintain efficiency and prevent mineral buildup, we recommend a professional descale/flush every 12 months. This is a simple maintenance step that protects your long-term investment.

What are common issues that require water heater repair?

Common issues include no hot water, inconsistent water temperature, leaks, strange noises, and error codes. These problems can affect both tankless and traditional water heaters and require professional repair​.

How does regular maintenance impact the lifespan of my tankless water heater?

It is recommended by Manufacturers that once yearly maintenance be performed.  However incoming water temperatures, frequency of usage and water quality  greatly affect how often maintenance needs to be performed.  It’s best to let the Service Technician recommend maintenance frequency.

What should I consider when choosing a tankless water heater for my commercial property?

Consider the hot water demand, the number of fixtures, the type of fuel (natural gas, propane, or electric), and the specific requirements of your property. Consulting with a professional can help you determine the best system for your needs.

How do commercial tankless water heaters contribute to energy savings?

Commercial tankless water heaters are highly efficient as they only heat water on demand, reducing energy waste. This efficiency translates to significant savings on utility bills, especially for businesses with high hot water usage.

Are there any specific maintenance requirements for commercial tankless water heaters?

Yes, regular maintenance is crucial for commercial tankless water heaters. This includes descaling, checking the heating elements or burners, and ensuring proper ventilation. Routine maintenance helps prevent breakdowns and extends the system’s lifespan​.

Can a single tankless water heater meet the hot water needs of a large commercial property?

Depending on the hot water demand, multiple tankless water heaters can be installed in parallel to meet the needs of large commercial properties. This setup ensures that the system can handle simultaneous usage from multiple fixtures​.

What are the benefits of tankless water heaters for commercial properties?

Tankless water heaters provide endless hot water, energy savings, and space efficiency, making them ideal for commercial properties with high hot water demand. They also have a longer lifespan compared to traditional water heaters​.

How much does it cost to install a tankless water heater?

The cost to install a tankless water heater can range from $3,000 to $6,500, including the unit and installation. Factors affecting the cost include the type of heater, installation complexity, and any necessary upgrades to your home’s plumbing or electrical systems​.

What are the installation requirements for a tankless water heater?

Tankless water heaters require proper venting, a dedicated gas line or sufficient electrical capacity, and a location that prevents freezing. Professional installation is recommended to ensure safety and optimal performance.

Can a tankless water heater run out of hot water?

Technically, no. Tankless heaters heat water on demand, providing an endless supply. However, every unit has a maximum flow capacity. If you demand more hot water than the unit can handle at once (e.g., running three showers simultaneously), a properly sized tankless heater will automatically reduce the water flow to ensure the temperature remains consistent. You won't get cold water, but you may notice slightly lower water pressure.

Are tankless water heaters energy-efficient?

Yes, tankless water heaters are more energy-efficient than traditional tank water heaters. They only heat water when needed, reducing energy consumption and lowering utility bills. On average, they can be 24-34% more efficient for homes that use 41 gallons or less of hot water daily​.

What is a tankless water heater, and how does it work?

A tankless water heater heats water on demand rather than storing it in a tank. When you turn on a hot water tap, cold water flows into the unit and is heated by a gas burner or electric element before being delivered to the faucet. This process provides a continuous supply of hot water without the need for a storage tank.
