What customers say
This genuine OEM replacement coil is highly valued for ensuring a precise fit and restoring the MasterTemp 250 heater to peak efficiency. Customers express significant relief in successfully repairing their expensive unit rather than replacing it entirely. The coil performs reliably, quickly heating pools and spas as expected after proper installation. However, the core sentiment is one of grudging satisfaction due to the substantial cost. Reviewers consistently find the price exorbitant for a replacement component, which severely impacts the overall value perception. While the part itself is reliable, some note concerns about the inherent vulnerability of these coils to long-term corrosion.
