Tankless Water Heater Installation & Service in Katy, TX
Tired of running out of hot water mid-shower? On-demand heating means unlimited hot water, lower bills, and a unit that lasts nearly twice as long as a tank.
How a tankless water heater works
Traditional tank heaters keep 40–80 gallons hot around the clock, whether you need it or not. A tankless unit heats water only when you open the tap: cold water flows through the unit, passes over a high-powered heating element or gas burner, and arrives at your faucet hot within seconds.
The result is unlimited hot water, lower energy waste, and a unit that can last 20+ years — nearly double the lifespan of a conventional tank heater. Units are wall-mounted and roughly the size of a carry-on suitcase, freeing the closet or garage space a 50-gallon tank occupies.
Is the switch worth it?
Tankless units are 24–34% more energy-efficient than storage tanks for homes using under 41 gallons per day — real savings, year after year, in the Houston heat. Installed cost typically runs $1,000–$3,500 depending on fuel type and whether gas line or electrical upgrades are needed, and most homeowners recoup the investment within 5–7 years through energy savings alone.
Not every plumber is qualified for this work — proper sizing, venting, and gas line changes require licensed expertise. Our installations are code-compliant and permit-ready (Master Plumber MPL #36673, HVAC TACLB119162E), and we're locally based, so we know the hard-water conditions and building codes unique to Fort Bend and Harris County.

Common questions
Tankless Water Heaters in Katy — answered
Don't see your question? Ask a real person — we answer the phone 24 hours a day, every day of the year.
281-601-1513How much does a tankless water heater cost installed?
Typically $1,000–$3,500 installed, depending on fuel type (gas vs. electric) and whether gas line or electrical upgrades are needed. Most homeowners recoup the investment within 5–7 years through energy savings. Estimates are free and upfront.
How long does a tankless water heater last?
Quality tankless units last 20 years or more with proper maintenance — nearly double the 8–12 year lifespan of a conventional tank heater.
Does Katy's hard water affect tankless units?
Yes — mineral scale builds up inside the heat exchanger. That's why we recommend an annual descaling flush, which we perform as routine maintenance to keep the system at peak efficiency.
Can a tankless unit really supply the whole house?
A properly sized unit can. For larger households we recommend whole-home gas tankless systems for maximum flow rate — sizing is the assessment we do before quoting, not after installing.
Do you offer financing on tankless installations?
Yes — flexible financing options are available to qualified homeowners, so you can start on the energy savings without the upfront burden. Ask when you call for your free estimate.
