BelliSlimo sets new industry standards with its modern Italian design and latest technologies. With a slim silhouette of 28 cm in depth, two tanks and two separated stainless steel heating elements, it offers a first shower in less than 40 minutes.

Designed to be connected directly to the mains cold water supply, the TESY unvented hot water cylinders provide fast and efficient hot water with low energy consumption and simple installation.

Simply connect the cylinder to a mains cold water supply on the inwards feed connection and connect the hot water pipework to the outwards feed connection cylinder (both connections are 15mm, connect to a 13amp fused spur and the Bellislimo will provide efficient hot water.

The unique design offers an adjustable temperature control to allow the user to select the desired water temperature with high efficiency water heating.

  • WORK ON DEMAND MODE: BelliSlimo thinks for you and calculates by itself the time required for your water to heat up just on time
  • ENERGY EFFICIENT: In the highest possible in its range – Energy class B
  • ECO SMART MODE: Self-training and self-management
  • DOUBLE TANK: Two water tanks with separate heating elements
  • REVERSE COUNTER: Counts down until the electric water heaters reaches the desired temperature
