Our Founder

Natalia Calvo is the founder of On Call Water Heaters. Natalia got into the water heater business in 2006 as a sales lady for her father’s company.  She did so well, that in time; she got her own workers and jobs. She decided to do this alongside her Dad but with her own business name.  Natalia decided to target a different area and higher income customers which enabled her to put things in place that the company never had. These are some key things that On Call Water Heaters offer today; Natalia still works alongside her Dad and continues to learn more from him. Natalia’s goal is to make On Call Water Heaters a successful business that her son can take over and grow with. This amazing journey has all been thanks to her dad and she really cherishes his wisdom and the great amount of time he is given to her.
