Ryuhic Inflatable Hot Tub (Round 4 Person With LED)

How long does it take to heat the water to a comfortable temperature?

The 1350W heater raises water temperature by 1-2°C per hour. Starting from typical UK tap water temperature of around 15°C, it takes approximately 12-15 hours to reach the maximum 40°C. However, most people find 35-37°C comfortable, which takes about 10-12 hours. The insulated cover helps retain heat between uses, reducing reheating time significantly.

What are the running costs for electricity?

The heater uses 1350W when actively heating. At current UK electricity rates of approximately 30p per kWh, it costs about 40p per hour when heating. Once at temperature, the thermostat cycles on and off to maintain heat, typically using the heater 20-30% of the time. Daily running costs average £2-4 depending on outside temperature and usage patterns.

How often do I need to change the water?

With the dual filtration system running properly, water typically stays clean for 1-2 weeks with regular use by 2-4 people. Factors affecting water life include bather load, use of chemicals and maintenance of proper pH levels. The system alerts you when filters need changing after 168 hours of operation, which helps maintain water quality longer.

Can this hot tub be used year-round in the UK?

Yes, the hot tub is designed for year-round use in UK conditions. The powerful heater and insulated cover work effectively even in winter temperatures. However, heating costs increase in colder months and you may need to run the heater more frequently. The puncture-resistant PVC material handles temperature variations well, though you should clear snow buildup from the cover.

What chemicals do I need to maintain water quality?

You'll need chlorine or bromine sanitiser, pH adjusters (pH plus and pH minus) and alkalinity increaser. Test strips help monitor chemical levels weekly. Shock treatment may be needed after heavy use. The filtration system reduces chemical requirements compared to hot tubs without proper filtration, but regular chemical maintenance is still essential for safe, clean water.

How much space do I need for installation?

The hot tub measures 180cm diameter, but you need additional space around it for access and equipment. Allow at least 2.5m x 2.5m total area on level, firm ground. You'll also need access to a standard 13-amp electrical socket within reach of the power cable. Consider drainage access for water changes and ensure the location can support the weight when filled.

Is the LED lighting safe to use in water?

Yes, the integrated LED strip is fully waterproof and designed specifically for hot tub use. The lighting system operates on low voltage through the main control unit, making it completely safe for users. The 8 colour settings are controlled via the main panel and the LEDs are energy-efficient, adding minimal cost to your electricity usage while providing excellent ambiance.

What's included in the package and what do I need to buy separately?

The package includes the inflatable hot tub, heater pump unit, filtration system with two filter cartridges, insulated cover and setup instructions. You'll need to purchase water treatment chemicals, test strips and replacement filters separately. A ground sheet is recommended but not essential. All necessary inflation and setup equipment is included in the box.
