Tired of running out of hot water, or short on closet space? Real Texas Plumbing Heating and Air installs tankless water heaters in Lago Vista, Jonestown, Point Venture, The Hollows and Lakeway. We size the unit to your home, check your gas line or electrical panel before we quote, and give you the price in writing before we start. The $65 trip charge goes toward the job when you schedule.
Often, yes: for bigger households, lake houses that fill up on weekends, and anyone short on space. Not always: for a small household that rarely runs out of hot water, a tank costs less to buy and install. Your fuel, your panel, and our hard water decide most of it, and the sections below show how.
Tankless costs more than a tank, which runs $2,200 to $4,400 installed. The difference usually comes from the gas line size, venting, electrical work, and whether the unit replaces a tank in a tight closet. Your written quote lists each item, and the $65 trip charge is applied toward the work when you schedule.
Up-front cost: lower for a tank, higher for tankless.
Typical life: a tank lasts 8 to 12 years, less in hard water. A tankless can last up to about 20 years with regular maintenance.
Hot water: a tank is limited by its size and needs time to recover. A tankless is continuous, if the unit is sized right.
Space: a tank needs floor space. A tankless is wall-mounted.
Maintenance in hard water: a tank needs an annual flush. A tankless needs an annual descale, and skipping it shortens its life most.
Power: a tankless needs electricity to run, even gas models.
Best for: a tank suits smaller households and the lowest install cost. A tankless suits larger households, lake houses and tight spaces.
Propane or natural gas: a whole-home tankless burns far more gas at once than a tank does. Before we quote, we check the size of your gas line, your propane regulator, and the vent path. A line that fed a tank may be too small for a tankless.
Electric: whole-home electric tankless units can draw more power than many older panels have to spare. We check your panel's capacity first, and we tell you if an upgrade would be needed before you commit.
Venting: gas units vent through a wall or roof, and condensing models also need a drain for condensate. We plan the route before we quote.
Water around Lago Vista is hard. The minerals form scale inside a tankless heat exchanger, which shows up as error codes and weak flow. Plan on a descale once a year, which is included in our maintenance plan. A water softener protects the heater, and we will tell you honestly whether your home needs one.
We size a tankless by how much hot water you use at once and how cold your incoming water is in winter, not by square footage. A typical shower runs about 2 to 2.5 gallons per minute, so two showers, a dishwasher and a washer starting together add up fast. We add up your real peak use and pick a unit that holds up in January.
A tankless heats nothing while the house is empty, then keeps up when everyone arrives on Saturday. If your place sits idle between visits, tell us. It is one of the reasons tankless can make sense here.
Tankless units need electricity for their controls and freeze protection. In a long outage during a hard freeze, follow the manufacturer's drain-down steps. When we install, we show you where the drain valves are.
Consultation: we look at your hot water use, existing heater, gas line or panel, and where the unit will go.
Written estimate: you get your options and the price in writing before any work starts.
Installation: most tankless installs take 4 to 6 hours. Gas line upgrades, venting changes or electrical work can add time.
Testing and walkthrough: we check performance and safety, then show you how to run it and when to service it.

Understanding the benefits and processes of switching to a tankless water heater.
For larger households, lake houses and tight spaces, often yes. For a small household that rarely runs out of hot water, a tank costs less. We will give you real numbers for both.
Usually 4 to 6 hours. Gas line upgrades or electrical work can add time.
Most can. Propane homes may need a larger gas line or regulator, electric units may need more panel capacity, and every unit needs a vent path. We check before we quote.
Up to about 20 years with regular maintenance, which is roughly double a tank. Descaling matters most in hard water.
Yes. Plan on a descale once a year. It is included in our maintenance plan.
Not if it is sized right. We size to your peak use and your winter water temperature.
It depends on what your home already has and what your panel can carry. We price both when it makes sense.
It has no standby loss, so it can lower energy use, but savings vary with household size. We will not promise a number we cannot back up.
Discover why they choose us
We had a great experience with Real Texas Plumbing! We came home to our grinder pump being out. They were here first thing in the morning on a Sunday replacing it. They beat our first estimate by around $1500. They will be our go to company for plumbing and HVAC in the future.
Friendly and knowledgeable techs came out, confirmed the problem and replaced what was needed. A very fair price compared other companies I had come out the day before.
Very prompt arrival to fix leak in-ground, fixed everything in about an hour, very reasonable price, and glorious to be able to turn on a faucet or shower and get WATER!. I would/will use them again should any need arise. RECOMMENDED!
