What is the difference between millivolt and electronic ignition in gas pool heaters?

A millivolt pool heater has a standing pilot (meaning it is always lit). This uses a small amount of energy as well as it can attract bugs and vermine to its warmth. Millivolt heaters are considered older technology. Electronic ignition heaters have electronics that allow the pilot to be lit only just when you are starting the heater. These electronic componants usually also allow for self-diagnostic features on most heaters. This is considered newer technology and is the direction the industry is moving in. Millivolt heaters are usually slightly less expensive and are easier to work on mechanically, but electronic heaters are becoming more popular and technicians are learning to work on them more and more and they will soon replace Millivolt heaters.
