{"product_id":"26-58509","title":"Balboa BP100 15\" 5.5kW Flo-Thru Heater (26-58509)","description":"\u003cp\u003eBalboa BP100 15\" 5.5kW Flo-Thru Heater (26-58509) is a 5.5kW replacement heater intended for compatible Balboa BP100 spa systems. Because heater output directly affects electrical demand and heating performance, confirming both the original part number and system rating is essential before installing a higher-output replacement assembly.\u003c\/p\u003e\u003cp\u003eBP100 systems are compact control platforms, so the heater assembly is an integrated part of the overall equipment layout rather than an interchangeable stand-alone component. Selecting the correct heater helps preserve the relationship between circulation flow, control logic, electrical load, and the physical space available in the equipment bay.\u003c\/p\u003e\u003cp\u003eWith a 5.5kW heating rating, this model provides greater heating capacity than lower-output 1.5kW, 2.0kW, 3.0kW, or 4.0kW alternatives. That higher output can support faster temperature recovery when used in the system for which it was designed, but it also carries different electrical demands. The spa’s control system, wiring, and breaker configuration must be appropriate for the specified heater load.\u003c\/p\u003e\u003cp\u003eProper fitment begins with verification. Compare the existing heater’s part number, length, rated output, sensor or control connections, plumbing orientation, and electrical requirements before ordering. Spa heaters are not universally interchangeable, and taking a few minutes to confirm these details can reduce installation delays, unnecessary returns, and repeat service calls.\u003c\/p\u003e\u003cp\u003eOnce correctly matched and installed, the Balboa 26-58509 can help restore dependable water heating, steadier temperature maintenance, and the day-to-day comfort expected from a properly operating spa.\u003c\/p\u003e\u003cul\u003e\n  \u003cli\u003eDesigned for compatible Balboa BP100 spa control applications\u003c\/li\u003e\n  \u003cli\u003e5.5kW rated heating output\u003c\/li\u003e\n  \u003cli\u003e15\" heater configuration for correct physical fitment\u003c\/li\u003e\n  \u003cli\u003eMatch original electrical, plumbing, and control-system requirements\u003c\/li\u003e\n  \u003cli\u003eSupports dependable temperature recovery when correctly matched and installed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Therm Products","offers":[{"title":"Default Title","offer_id":49079914889371,"sku":"26-58509","price":176.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1751\/9347\/files\/26-58509.jpg?v=1784868215","url":"https:\/\/www.bathandspaparts.com\/products\/26-58509","provider":"Bath and Spa Parts Online","version":"1.0","type":"link"}
