KATY, TEXAS
Tank & tankless water heaters
Your home
sets the brief.
A tankless conversion is more than a change of appliance. The household’s peak demand, the existing fuel or electrical supply, water connections, and the available installation location all need a look.
For a larger home, the fixtures running at the same time matter more than a headline capacity figure. The system’s output at the temperature rise you need helps determine the right equipment and configuration.
If you prefer to keep a storage tank, we can discuss replacement options and capacity for your routine. The aim is a system suited to your home, with the work explained before you choose a date.

Endless hot water for Katy households.
Katy keeps its small-town charm while it grows fast across three counties: Harris, Fort Bend and Waller. Whether you’re coming home from Katy Mills, dinner at LaCenterra at Cinco Ranch, an afternoon at Mary Jo Peckham Park or the Katy Heritage Museum, or getting the kids ready for school in Katy ISD, a cold shower shouldn’t be on your list of worries.
Our founders, Tom Massimin and Kenny Browning, have spent nearly 20 years serving neighbors across Cinco Ranch, Seven Meadows and Old Town Katy with honest expertise. We specialize in moving Katy households from traditional, inefficient tanks to tankless technology, and in the plumbing needs of Katy’s master-planned communities, from established homes in Nottingham Country to high-efficiency new builds in Cane Island and Elyson.
Why we recommend tankless for your Katy home.
- Unlimited hot water. You won’t run out, however many showers, laundry loads or dishwasher cycles run at once.
- Space back. Wall-mounted tankless units take up 75% less space than a traditional 50-gallon tank, so the garage or utility closet is yours again.
- Energy savings. A tank wastes energy on standby, heating water you aren’t using. A tankless unit only activates when you turn on a tap, which can cut energy bills by up to 34%.
- Cleaner water. With no storage tank to collect sediment or corrode, your family gets better water quality.
- A 20-year lifespan. Our tankless installations are designed to last 20 years or more. A standard tank in the Houston area typically lasts 6 to 8.
Permits in the City of Katy.
The City of Katy requires a plumbing permit for every water heater installation and replacement. The permit means a third-party inspector verifies that the temperature and pressure (T&P) relief valve and the venting meet the latest safety standards, and Texas requires a licensed master plumber, the Responsible Master Plumber, to pull the permit and oversee the installation. We handle the technical and administrative details for you.

When the hot
water changes.
A change in performance is a reason to have the equipment assessed. We help you understand the fault and whether repair or replacement is the practical next step.
Discuss a repair
An error code on the unit.
Make a note of the code and model, if you can see them safely. That information is a useful starting point for a tankless repair conversation.
Maintenance that’s due.
Mineral scale can build up in a tankless heat exchanger. Follow the manufacturer’s care guidance, with the service interval based on water conditions and usage. Ask about descaling, filters, and the checks appropriate to your equipment.

The Katy homeowner
checklist.
Katy water, sizing a Cinco Ranch home, repairs and your monthly energy bills.
How does the water in Katy affect my water heater?
Katy water can lead to mineral buildup. Our specialized descaling services remove those deposits, so your unit stays energy-efficient and avoids unexpected breakdowns.
Can one unit handle my home in Cinco Ranch?
Absolutely. During the consultation, we assess your peak usage, meaning how many showers and appliances run at once, and recommend a system that guarantees you never run out of hot water.
What happens if my system needs a repair?
As authorized specialists for major brands, we carry the parts and the technical knowledge to fix it right the first time. We’re known for our responsiveness, and our trucks carry the most common OEM parts, so most repairs are finished in a single visit.
Do I really save money on my monthly bills?
Yes. Because you stop paying to heat water 24/7, most Katy families see a noticeable drop in their energy bills, often up to 34%.
