About
Family Large with Dual heat pump brings hot and cold functionality to a generous 6–8 person format. It is ideal for larger families, social gatherings and contrast therapy sessions. The integrated family bench improves accessibility and safety. It makes entry and exit easier, provides stable seating for children and allows relaxed back and arm support during bathing. The Dual air-source heat pump system combines heating and cooling, including circulation, filtration, ozone purification and a control panel. Temperature changes occur at approximately 4–5°C per hour in large tubs, depending on conditions. The exterior is built from durable thermo-treated pine, selected for its stability and long-term outdoor performance. Inside, the LightGray liner is smooth, hygienic and easy to maintain. An insulated EN 17125 standardized safety cover is included to protect the water, improve energy efficiency and increase safety. Wooden steps are delivered pre-assembled. With optional LED lighting, the bathing experience becomes more atmospheric. Factory-installed lights emphasize the tub’s colours and add a gentle glow for relaxing moments after dark. Manufactured in Finland and developed on more than 25 years of Nordic hot tub expertise from Kirami — part of the Harvia team since 2021 — Family Large Dual is built for dependable year-round use.
