We have this cold plunge- https://firecoldplunge.com/products/the-fire-cold-plunge-tub?variant=49447003357464

The chiller has dropped working completely, we’ve cleaned filters and cleared all of the lines. We’ve drained and cleaned and refilled and can not figure out the issue. We also can’t find a repair person to come and take a look. So now we are resorting to buying an external chiller. We live in Texas, and my husband liked to keep it around 48 degrees, what are the best external chillers that we could easily use with this plunge.
