Tankless heaters also allow you to get hot water anytime you need, unlike conventional heaters which may require you to wait a while before hot water arrives in the faucet.
Another notable advantage of using a tankless water heater is that it is usually located close to the shower or the faucet, allowing you to get hot water without the water losing its temperature. In contrast, a conventional heater may transport water over some distance to bring it to your shower, losing some of the temperature along the way.

(512) 598-4241Frequently Asked Questions
How much does a tankless water heater cost to install?
The upfront cost of a tankless unit is higher than a traditional tank, but the long-term energy savings and longer lifespan often make it a more economical choice over time. We provide free, detailed estimates tailored to your specific home.
Will my home's gas line need to be upgraded for a gas tankless heater?
In some cases, yes. Gas tankless units require a larger gas line than traditional tanks to operate effectively. During our free consultation, we will assess your existing gas line and include any necessary upgrades in your upfront quote.
Why is my tankless heater showing an error code?
Error codes are the system’s way of self-diagnosing a problem, which can range from a simple ignition failure to a blocked air vent or an internal component issue. Our technicians can quickly interpret these codes and perform the correct repair.
How often does my tankless unit need maintenance?
We strongly recommend professional maintenance once a year. Annual descaling is essential in the Round Rock area to remove hard water mineral deposits, which will otherwise reduce efficiency and damage the unit.
