Balboa Spa Packs are designed for replacement or retrofit applications in hot tubs that have 1 to 4 jet pumps. They feature Wi-Fi-ready circuit boards and utilize Balboa’s M7 heater technology, which is sensor-based and eliminates the need for a pressure switch, ensuring long-term reliability. The BP7 bundles also include a topside control panel, spa light cord, and keypad adapters, all of which facilitate a seamless and easy installation process to get your hot tub up and running.
