Install a Water Heater Built for Your Home

Code-compliant water heater installation services for homeowners in Spicewood

When you are building a new home, remodeling a bathroom, or replacing an outdated system, choosing and installing the right water heater matters more than many homeowners realize. In Spicewood, where household sizes vary and lakeside properties may have different usage patterns than suburban homes, the size and fuel type of your water heater directly affect how well it keeps up with demand. A unit that is too small leaves you running out of hot water during showers or laundry, while one that is oversized wastes energy and takes up unnecessary space.


Marble Falls Plumbing LLC installs both gas and electric water heaters, helping you select the right model based on your household's daily usage, the number of bathrooms, and your long-term energy efficiency goals. The installation process includes connecting supply and discharge lines, setting up proper venting for gas units, installing temperature and pressure relief valves, and ensuring everything meets local plumbing codes and manufacturer specifications. Installations in Marble Falls homes account for local water conditions that can affect heater lifespan, such as mineral content that leads to sediment buildup over time.

What goes into setting up a new water heater

Installation begins with selecting a location that allows for safe venting, drainage, and access for future maintenance. In Spicewood, most installations take place in garages, utility closets, or attic spaces depending on home layout and code requirements. Gas water heaters require proper venting to the outside, while electric models need dedicated circuit breakers and appropriate wiring. The unit is set in place, leveled, and secured before water lines and gas or electrical connections are made.


Once the installation is complete, you will have consistent hot water that recovers quickly between uses, lower energy costs if upgrading from an older model, and a system that operates safely without leaks or venting issues. The water heater will be labeled clearly, and you will know where the shutoff valve is located in case you ever need to turn off the water supply.


The work includes testing the system for leaks, verifying temperature settings, and confirming that pressure relief valves function correctly. If you are upgrading from an older unit, the installation may also involve replacing corroded supply lines or updating drain pans to meet current standards. The service focuses on clean workmanship and long-term reliability, but it does not include removing old units unless that is arranged separately. Proper setup from day one helps avoid callbacks and ensures the heater performs as intended for years.

We know you have questions about the install

Most homeowners want to know what the installation involves, how long it takes, and what decisions they need to make before the work begins.


  • How do I know what size water heater I need? The size depends on how many people live in your home, how many bathrooms you have, and your peak usage times. A household of four typically needs a 40 to 50 gallon tank, but usage patterns and appliance demands can shift that recommendation.
  • What is the difference between gas and electric water heaters? Gas water heaters heat water faster and cost less to operate in most cases, but they require venting and a gas line. Electric models are easier to install in homes without gas service and work well for smaller households with lower demand.
  • How long does a water heater installation take? Most installations are completed in three to five hours depending on whether new venting, gas lines, or electrical work is required. You will have hot water the same day once the system is tested and filled.
  • What happens to my old water heater? If removal is part of the service, the old unit is disconnected, drained, and taken away. Some installations are for new construction or additions where no existing heater needs to be removed.
  • Why does local water quality matter for installation? Hard water with high mineral content is common in Spicewood and can cause sediment to build up inside the tank over time. Knowing this ahead of time allows for recommendations on anode rod types and maintenance schedules that help extend the life of your new heater.
