Experience a new era in intelligent hot water heating with the TESY BelliSlimo Wi-Fi 80 Litre Electric Hot Water Boiler. This advanced appliance learns your household’s hot water habits, delivering maximum efficiency and lower running costs than traditional cylinders. With an 80 litre capacity, it’s perfect for homes of up to four people and provides up to 23 minutes of continuous hot water. The fast heat-up time of just 2 hours 11 minutes means you’ll never be left waiting. Enjoy the flexibility of Wi-Fi control via the TESY app, allowing you to manage your hot water remotely from your smartphone. Prefer a hands-on approach? The intuitive touch screen on the front lets you operate and programme the boiler directly. The BelliSlimo features two unvented, glass-coated internal tanks, each with its own copper heating element. This double-tank system ensures hot water is always delivered at the right temperature for maximum comfort and efficiency. Key features include WORK ON DEMAND mode, which calculates when your water will be ready, ECO SMART self-learning technology for tailored energy savings, and a BOOST function for quick hot water. The CFC-free insulation minimises heat loss, and the ceramic-lined tanks ensure long-lasting, corrosion-free performance. Installation is straightforward—simply connect to a mains cold water supply and a fused spur/circuit breaker electrical connection. The BelliSlimo is unvented and provides mains pressure hot water to all taps and showers. For safety and compliance with UK Building Control regulations, at least one safety device (such as an expansion vessel or pressure relief valve) must be installed. With features like holiday mode, reverse counter display, and a quick first shower function, the TESY BelliSlimo Wi-Fi 80 is the smart choice for energy-efficient hot water. Its slim, space-saving design (Height: 1,057mm, Width: 490mm, Depth: 280mm) fits perfectly in any modern home.
