Elviona SERENA is a seven-person massage hot tub designed for relaxation and water massage. The hot tub is well suited for outdoor use but can also be installed in appropriately prepared indoor spaces. It features seven ergonomic seats without loungers, allowing all seven people to enjoy water massage in a seated position. This layout is particularly suitable for spending time with family or friends.
The hot tub is equipped with 105 massage jets - 93 water massage jets and 12 air massage jets, positioned in different massage zones. Three hydro massage pumps (one rated at 3.0 HP and two at 2.0 HP) supply water to the massage jets, while a 700 W air blower creates an additional bubbling effect. Water massage intensity can be adjusted to individual preferences.
Construction and thermal insulation
The hot tub shell is made from acrylic supplied by the US manufacturer Aristech and reinforced with fiberglass. The exterior cabinet is made from weather-resistant synthetic material, while the supporting frame is constructed from grade 304 stainless steel.
Several insulation features help reduce heat loss:
- Nordic double-insulated thermal cover;
- Additional insulation for the hot tub shell;
- Exterior cabinet insulation made from foam and heat-reflective aluminium foil;
- Insulated bottom base with a 5 mm insulation layer;
- Sealed fiberglass-reinforced plastic (FRP) bottom panel;
- An additional 25 mm layer of foam insulation between the hot tub frame elements.
Water heating and control
Elviona SERENA is equipped with a USA BALBOA control system and a 3 kW water heater. The control panel allows users to adjust the water temperature and operate the main hot tub functions.
Water filtration
A separate 0.35 HP circulation pump ensures water circulation through the filtration system. The skimmer and two cartridge filters help collect and capture mechanical impurities, while the integrated ozone system and UV water disinfection system provide additional water treatment.
Lighting and comfort
The hot tub features 38 multicolour LED perimeter lights, additional bottom lighting and LED-illuminated air massage jets. Four LED-illuminated headrests provide additional comfort, while massage jets arranged across the seating positions allow users to enjoy different water massage zones.
