Lay-Z-Spa 54123 Heater Pump Unit - Tested Working, 220-24OV, 2050W
The 54123 is the original egg-shaped heater pump for the Bestway Lay-Z-Spa Miami AirJet model and is a direct fit for that tub. Just the heater unit and all hoses. Used but in good condition. All you need is the tub - which is the cheap part!
