Why choose a Vortex Gemini?

Luxury 2 person spa

The Vortex Gemini is a compact 2 person luxury spa. It is a feature packed spa with powerful jets, water features and a fantastic lighting package. As the Gemini uses the same big pump as our larger spas you get tremendous jet pressure and therefore hydrotherapy is extremely effective.

Vortex quality

It might be the smallest spa in the Vortex range, yet the Gemini comes complete with a locking hard cover and Vortex's great 4 layers shell construction that is covered by a comprehensive 10 year structural warranty.

How we rate our spas

Choosing the right spa can be confusing. Especially when faced with many options to choose from. To simplify this process, we have used our years of spa experience to create a simple rating system that compares our huge range of spas across a number of important attributes.

Gemini Features

tranquil water feature
Tranquil water feature

The Tranquil water feature gives your spa a relaxing feel. This water feature runs of the filtration pump, so it can be left running while your spa is not in use- turning it in to a garden water feature.

jet pressure controls
Independent seat pressure controls

In the Gemini you can control the jet pressure to each seat. As the Gemini uses the same size pump as the larger Vortex spas, the the jets offer a high level of hydrotherapy.

Energy Efficiency

Consumption at rest
Consumption in use
Variable Output Heater

The heater of your spa draws more power than any other component. As a result, when the big jet pump or pumps turn on, the heater usually has to turn off, as unless your spa is hard wired, a conventional outdoor power point cannot provide enough power to run the heater and big jet pump at the same time.

The Vortex Gemini however, has a variable output heater. This means when the spa's jet pump is turned on, the heater turns DOWN rather than OFF. This has the benefit of maintaining the spa's temperature while you are using it, rather than cooling it down.

High densityHigh Density Lid

As heat rises, most of the heat loss in a spa occurs through the spa's cover. As such, it is important that the spa's cover is manufactured from a high density foam that has better heat retention properties. The Vortex Gemini uses a high density foam insert which is also heat shrink sealed to prevent water ingress, prolonging the cover's life.

insulated base
Insulated Base

The insulated base works in tandem with the perimeter insulation to ensure the cold is kept out and heating costs are reduced.

peremiter insulation
Perimeter Insulation

There are several ways to insulate a spa. Vortex spas have chosen to use perimeter insulation. Whilst more expensive to produce than foaming the shell of the spa, it does have the benefit of insulating the water that is in the plumbing of the spa, as well as the water in the spa itself.

dual layer insulation
Dual Layer Insulation

Acting like double glazed windows, the dual layer insulation system traps air between the foam insulation on the shell and the reflective foil and foam insulation of the cabinet, to create a pocket of warm air.

This system ensures that not only the water in the spa is insulated, but also the water in the pipework. This option adds a higher level of heat retention than Vortex’s standard perimeter insulation.

arctic insulation
Arctic Insulation*

Vortex Spa’s optional Arctic pack insulation is the ultimate level of insulation available. It increasing the thickness of the perimeter insulation to 50mm gives unsurpassed heat retention and the lowest possible running costs.

This system is extensively used on Vortex Spas sold in very cold regions such as Scandinavia and Canada.

Shell Construction
Thermobond shell construction

Vortex Spas use a 4 layer thermobond shell construction in the manufacturing of all of their spa shells.

The first layer is acrylic which gives the spa its colour. This is backed by a water proof, vinyl ester resin, marine grade polyester resin, which adds torsional strength, and, finally, a polyceramic layer which adds rigidity.

The shells are oven cured to ensure the correct bonding of the various layers. This is a crucial step that is missed by most manufacturers due to its additional cost.

Flexible PVC Plumbing

In order to eliminate the chance of kinks in the plumbing and to prolong life, Vortex Spas use a flexible PVC plumbing material called Duraflex. This is a flexible tubing that incorporates a spiral of rigid PVC. Unlike the tubing used by many manufacturers, Vortex Spas Duraflex plumbing is specifically designed for hot, chemically treated water and carries a 5 year no leak guarantee.

Timber-free frame

Vortex’s Permaframe construction is a timber-free framing system that is impervious to rot, mildew or vermin damage. Produced used high impact, injection molded plastic, it is designed to last indefinitely.

Vermin Proof Base

Vermin, snakes and rodents love the underside of spas as it is warm and dry. To repel unwanted visitors, the Spectrum Hydroplus features a sealed, Vermin proof base and cabinet design.
