tank-less water heaters

The new standard in water heaters is tankless. Newer model tankless water heaters are more energy efficient thus cutting energy costs. We love doing anything that helps keep our environment clean and that's why we highly recommend upgrading to a tankless hot water heater system.


Texas Plumbing will beat any licensed plumbers written quote on the installation of a tankless water heater. Our installers are licensed, insured, and will have your tankless water heater solution professionally installed for your application in no time.


Manufacturer recommends annual service on water heaters whether they are tank or tankless. Keeping up with your annual service will prolong the life of your water heater. Tank type water heaters need to be replaced every 5-10 years. If your water heater is older than 10 years old it's time for a replacement or an upgrade.


We install, service, or repair gas or electric water heaters. If your water heater is making weird noises, has rust, water pooling up, or you simply want to upgrade to a new one give us a call today. Professionals are standing by to answer any questions you may have.
