Bestway Solar Pool Heating Mat Pad

Impressed – Bought this to help heat a Bestway Miami Spa, connected to a 24v solar heating pump and a solar panel this pad increased the spa temp to 35 degrees in 5 hours, just needing the spa's heater to be used to boost the temp to 38 degrees. Compare it's to the spa's heater raising temp by about 1 degree per hour using 2000 watts. Well made and has standard threads to easily McGiver some connections.
