 "Has Solved The Bad Tankless Water Heater Installation Problem  

Their system saves time and money and is worry-free, with no maintenance.

Frisco, Texas, May 1, 2026. With consumer interest growing in sustainable home energy solutions, tankless water heaters have exploded in popularity. Unfortunately, many plumbers lack the knowledge of how to install or diagnose a problem with a tankless water heater, resulting in an unsafe, expensive, and time-consuming installation that, in most cases, will only last a few years.

Best Tankless USA.com, experts in tankless water heater installations for more than 17 years, has developed a solution to that challenge."

Hot Water Tanks to be Eliminated

The Federal government’s mandated energy-saving requirements by 2027 have eliminated the use of standard tank water heaters and placed greater emphasis on tankless water heaters, which are by far the most efficient for water heating.  



Frequently Asked Questions

Please contact us if you cannot find an answer to your question.

We offer you a free estimate but you must fill out our request for an estimate form.


Warranty

Our exclusive 5-year Parts and Labor Warranty covers only the Rheem/Culligan tankless Pre-Assembly package. This warranty covers all components under normal operating conditions. The Rheem/Culligan tankless package includes the RTGH-95DVLN-3, service valves, pump, pan, piping, PVC venting connection, and valves. 


Our warranty does not include components damaged by high water pressure over 75 psi, any component freezing, like filter housing, pan drain, pipe freezing, power failure damage, or any customer-caused damage. Also, it does not include piping connected to the TUSAP Pre-Assembly, existing metal roof vent leaking and sink supply lines, or existing sink valves/stops where the crossover valve is connected. Also, does not include filter cartridge replacement or flame rod service caused by dirty natural gas. 


This warranty works in conjunction with Rheem's warranty.



The number of tankless units needed in a home is based on the number of showers you have. i.e., a 3-4 shower home only requires one TUSAP Rheem/Culligan Pre-Assembly Tankless System


Most homes built after 2009 should have larger gas lines needed to support a tankless system. Of the last 450 units we installed, we only had to upgrade  3 gas lines.

During our Free Estimate visit, we will determine if your home has larger gas lines.

If gas line modifications are required, we will show that cost on our final written estimate.
