Water Heater Installation in Texas
Need a new water heater? We install tank, tankless, gas, electric, and hybrid water heaters with proper connections, venting, and permits.
What Is Water Heater Installation?
Water heater installation involves removing your old unit and setting up a new water heater with proper connections, venting (for gas units), electrical wiring (for electric units), and code-compliant installation. This includes tank water heaters, tankless systems, gas, electric, and hybrid heat pump models.
The installation process varies by fuel type. Gas water heater installation requires connecting the gas supply line, installing proper venting to exhaust combustion gases, connecting water supply and outlet lines, and installing a T&P relief valve with a discharge pipe. Electric water heater installation involves connecting the unit to a dedicated circuit of the correct amperage and wiring the elements and thermostats. Both types require proper seismic strapping where required and accessible shut-off valves.
Choosing the right size water heater depends on your household's peak demand. A family of four typically needs a 50-gallon tank or a tankless unit rated at 8+ GPM. Undersized units run out of hot water during peak usage; oversized units waste energy heating water you don't use. Your plumber can calculate the correct size based on fixture count, simultaneous usage patterns, and incoming water temperature.
Texas building codes require permits for water heater installation in most jurisdictions. We handle the permit process and ensure every installation passes inspection. Proper installation protects your home warranty, insurance coverage, and family safety — especially for gas units where incorrect venting can cause carbon monoxide hazards.
