The Water Heater Warehouse

The Water Heater Warehouse operates as Fullerton's most reviewed water heater contractor, holding a 4.9-star average across 1,311 verified customer reviews. The company specializes exclusively in water heating systems rather than general plumbing, allowing technicians to pursue deep training on tankless technology. Homeowners throughout Fullerton and neighboring Orange County communities turn to this team when traditional tanks fail or when switching to endless-hot-water tankless systems becomes the better long-term choice.

Noritz tankless water heaters anchor the company's product lineup, and the team guides Fullerton-area customers through SoCalGas marketplace purchases to access rebates that can exceed $1,500 on qualifying installations. Factory-trained technicians complete ongoing certification directly through Noritz, translating into precise diagnostics and installations that minimize callback issues. Reviews confirm the team handles straightforward replacements and complex retrofits alike, using professional-grade copper piping installed to code on every project.

Customer reviews repeatedly highlight installer Chris Thorne by name for his patience, thorough explanations of system operation, and meticulous clean-up habits. Brian Jennings described Chris taking extended time to answer numerous questions during the installation process, with copper piping installed neatly and the work area left spotless upon completion. Lucinda Victoria reported a complete Noritz tankless installation finished within three hours, noting the technician discussed all options before starting work. Pat Biggers credited the office staff for excellent communication and praised technicians for arriving on time and performing exceptionally thorough work, stating she could not be happier with the outcome.
