LOVIA SPA's 4-person spa hot tub uses a 3kW heater 1. 110V: Requires approximately 28A, 30–40A circuit recommended 2. 220V: Requires approximately 14A, 16–20A circuit recommended 3. 380V (three-phase): Requires approximately 8A, 10A circuit recommended

The water temperature in the swim spa hot tub is typically maintained between 37°C and 40°C. This temperature range intensifies the ion exchange between magnesium salts and metals, causing corrosion to accelerate exponentially.

• Less than 10 minutes: This is a mild stimulation phase, aiding in skin circulation and initial relaxation. • 15-20 minutes: This enters the deep muscle relaxation and nerve soothing phase, the optimal range for therapy.

LOVIA SPA is one of China's well-known outdoor spa hot tub brands. Our 6-person spa hot tub measures 2300×2300×880 mm, with a dry weight of 350 kg and a weight of 2190 kg when filled with water.

Actual heating time for a 4-person spa hot tub + 3kW heater: 6–14 hours (from cold water to 38–40°C) Summer or higher outside temperatures: 5–8 hours Winter or lower temperatures: may require 12–16 hours

The location of the heater in a spa jacuzzi tub varies depending on the brand and model, but generally, it's installed at the bottom or beside the tub, near the water circulation system. These locations ensure effective heat exchange between the heater and the water flow, thus heating the water.

The inventor of the modern Jacuzzi tub is: Roy Jacuzzi Roy Jacuzzi is a member of the Jacuzzi company and its most important technology driver and spa equipment innovator. He and another key engineer at the company, Peter Kosta, developed the world's first truly integrated jet-powered Whirlpool Bath.

➡ If it is a movable spa hot tub → it is considered personal property. As personal property → Belongs to private assets. ➡ If it is a built-in or permanently installed spa hot tub → it is considered a fixed installation. As a fixed installation → Belongs to the property's appreciation.

Bubbles are a common phenomenon during the normal operation of a swim spa hot tub. Simply put, bubbles are generated from the mixing of air and water. When the nozzles, pumps, and air channels in the system inject air into the water flow, bubbles form in the water.

Bubbles and foam in a swim spa hot tub: Bubbles represent healthy circulation and a comfortable massage, a sign that the system is functioning properly; foam, on the other hand, is a signal of abnormal water quality, indicating organic contamination or chemical imbalance.

Immediately stop adding chlorine to prevent the concentration from rising further; open the swim spa hot tub lid for ventilation to allow the chlorine to evaporate naturally; check and adjust the pH level, maintaining it between 7.2 and 7.6.

A swim spa hot tub should never be operated without a filter. The lack of a filter will cause pump blockage, heater contamination, and nozzle clogging, resulting in irreparable mechanical damage; furthermore, deteriorating water quality will accelerate bacterial growth, affecting human health.
