This Hot Spot heater is a comparable after-market flow-thru style heater that can be used on the Solana TX, RX, and SX beginning in 2006, as well as the Hot Spot models beginning in 2006, except the Sprint and Dash. This heater is connected to the control box and to the spa’s plumbing using the attached compression fittings at both ends.

Technical Specs:
115 Volt AC, 1.0 kW, 8 Amps
220 Volt AC, 4.0 kW, 18 Amps

What if my spa is wired 110/120v? This heater works on both 120 and 240 volts spas. If your spa is wired for 120 volts, this heater will run at 1kW and draw 8 amps. If your spa is wired for 240 volts, this heater will run at 4kW and draw 17 amps.

This part can be found on many Hot Spot, Solana models from 2003 to 2023

Easy install, only removal of the plug for the pressure switch was an issue.
