Hot Spot® Series by Hot Spring Spas

Hot Spot models are FreshWater® Salt System Ready, engineered for the entry-tier FreshWater® Salt System, with the system sold separately or bundled by Seven Seas at install. This is not the IQ Salt platform, it is the standard FreshWater® Salt System without the IQ Smart Monitoring + Dosing upgrade path. Owners can run the Hot Spot on traditional chlorine or bromine and add the salt system later. The salt-water cycle "automatically generates chlorine from salt for soft, natural-feeling water without harsh odors, itchy skin, or irritated eyes" and can hold balance for up to a full year between drain-and-refill cycles when properly maintained.

Hot Spot uses the same FiberCor® high-density fiber-blend insulation as the Limelight® Series, Hot Spring notes the density is "four times greater than the half-pound foam used in most spas." Combined with the polymeric substructure with polyethylene sealed bottom, the Patented Pump Shroud, and the Energy Smart® System, the Hot Spot tier is engineered for low operating cost despite sitting at the entry price point.

Hot Spot models use Polyester Filters with a Free-Flow Core inside a 100% no-bypass filtration cycle, every drop of water passes through filtration during jet operation. The Polyester / Free-Flow Core is the entry-tier filter; the Tri-X® high-flow filter is a Limelight and Highlife feature. The Free-Flow Core design keeps water moving through the filter media at the lower flow rates typical of entry-tier pumps.

The IQ 2020® LCD Control, button-driven LCD, is the Hot Spot main control panel. It shares the IQ 2020® control architecture with the Limelight and Highlife tiers; Hot Spot uses the LCD button interface, Limelight uses the Color LCD button interface, and Highlife uses the Color LCD Touchscreen. The Hot Spring Spas App via the Connected Spa Kit is offered as an optional smart-control upgrade for remote temperature control and diagnostic monitoring.

Four of the six Hot Spot models, the Pace™, Stride®, SX, and TX, ship convertible between 115 V plug-and-play and 230 V hardwired. The TX is unique in the Hot Spring catalog for its 115 V / 15 amp plug-and-play configuration, the lowest amperage requirement Hot Spring offers, which lets it plug into many existing 15-amp dedicated circuits without a 20-amp upgrade or a new subpanel. The Rhythm® and Relay® are 230 V hardwired only.

Wavemaster® jet pumps power the jets across the Hot Spot Series, typically the 6000 (one-speed) and 6200 (two-speed) at 1.5 HP continuous duty / 3.2 HP breakdown torque on the larger models, scaling to single-pump configurations on the smallest models. The SilentFlo 5000® circulation pump runs continuously on less power than a 40-watt light bulb. The Patented Pump Shroud captures heat from the equipment compartment and transfers it to the water.

The SX and TX include a single-stream Moto-Massage® jet, the entry-tier patented version of Hot Spring's signature moving jet. One stream of water sweeps up and down the back from a stationary seat. This is distinct from the dual-stream Moto-Massage® DX used in the Highlife® Series (two streams). If you specifically want the patented Moto-Massage® action at the value tier choose the SX or TX.

The SmartJet® System is offered on the Pace™ within the Hot Spot Series, and only on the Pace™ within this tier. SmartJet® selectively distributes water flow to specific jet groups and seats, so a solo bather or a couple can route pump capacity to the seats they occupy rather than splitting it across the whole spa. Other Hot Spot models do not include SmartJet®. Across the broader Hot Spring catalog, SmartJet® is standard on the Highlife® Series.

The Energy Smart® System is exclusive to the Hot Spot® Series within the Hot Spring catalog and is engineered to reduce overall energy consumption further than the FiberCor® / Pump Shroud / sealed-bottom envelope alone. Combined with CEC and APSP 14 compliance, the system targets the lowest possible operating cost at the value tier.

Four of the six Hot Spot models ship convertible between 115 V plug-and-play and 230 V hardwired. The TX is uniquely 115 V / 15 amp (the lowest amperage in Hot Spring's catalog). The Rhythm® and Relay® are 230 V hardwired only. Plug-and-play installs need a dedicated GFCI-protected outlet within reach of the spa cord; 230 V installs need a licensed electrician to wire the included GFCI sub-panel. Seven Seas coordinates installation through the installation service.

The trade-off: a 230 V install delivers a 4,000 W heater (vs. 1,000 W on 115 V), faster recovery from cover-off, and the ability to run jets and heater simultaneously. The 115 V plug-and-play option removes the install cost and scheduling friction at the cost of slower recovery in cold weather.

Hot Spot filled weights span roughly 2,400 lbs (TX class) to 4,820 lbs (Rhythm® / Relay®). A level reinforced concrete pad, a deck rated for the filled weight, or a prepared spa pad is required, plus 24" of service clearance on at least one side. The TX's 6' × 6' corner footprint slots into spaces that don't accommodate a square or rectangular tub.

Every Hot Spot model is FreshWater® Salt System Ready, the entry-tier salt platform (non-IQ). The salt system itself is sold separately and commonly bundled by Seven Seas at install. Households can also run the Hot Spot on traditional chlorine or bromine and add salt later. If you specifically want the IQ Salt platform with optional Smart Monitoring + Dosing step up to the Limelight® Series (IQ Ready, system sold separately) or the Highlife® Series (IQ Salt included standard). If you want the simpler FROG® cartridge water-care platform instead of salt step down one tier to the Freeflow® Series.

Hot Spot® Series warranties run 5 years on structure and 2 years on shell surface / cabinet / no-leak plumbing / No-Fault® heater / components / interior lighting. The 5-year structure and 2-year shell coverage is the standard term across the Hot Spot Series. If you want longer coverage step up to the Limelight® Series (7-year structure / 5-year shell) or the Highlife® Series (7-year structure / 7-year shell). Below Hot Spot, the Freeflow® Series runs 5-year structure/shell, 2-year cabinet, 1-year plumbing, 1-year components, shorter than Hot Spot specifically on plumbing and components. Seven Seas honors and processes warranty claims for every Hot Spot sold.
