Calorex Fortis Instantaneous water heater

Calorex is a flagship brand in the Mexican market, recognized for its leadership in water heating solutions. Originally founded in Mexico, it has built a reputation over several decades for producing durable and efficient boilers tailored to local infrastructure needs. The brand was historically part of the Industrial Saltillo group (GIS) before undergoing a major corporate transition.

In 2019, the Italian heating giant Ariston Group (then Ariston Thermo Group) acquired Calorex, integrating it into its global portfolio. This acquisition allowed Calorex to combine its deep Mexican heritage and wide distribution network with Ariston's advanced European engineering and sustainable technology. Today, while the brand remains quintessentially Mexican in its identity and primary manufacturing base, it is backed by the global resources of one of the world's leading companies in thermal comfort.
