The TESY Bellislimo “un-vented” electric water heater with Wi-Fi offers the very latest innovation in intelligent and efficient electric hot water heating. The BelliSlimo is B rated for efficiency and thinks for you and calculates the time required to heat your water in order to deliver on time. It can be controlled and set by either the control panel or via the TESY App from your smart phone (Internet access required).

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 16amp 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

NB. Building Control regulations apply when safely installing an un-vented hot water cylinder. The Cylinders are unvented and require a small safety expansion vessel (5-8 litre) and a pressure release valve installing on the pipework in accordance with UK regulations.

The delivery is a ‘curb side’ delivery and the driver is not able to bring the goods into your  property for insurance reasons. Drivers will try their best to assist you as much as possible and most will help you move the stove to a safe place i.e on the door step or in the garage. The driver should arrive with a tail lift and pallet truck to move heavy stove items.

Steps and gravel drive ways can cause issues for the courier because of the item weight and equipment used. If inaccessible with their equipment, they may refuse to drop the goods or drop the goods at the curb side.

We will email you using your registered email address with delivery dates and instructions for receiving and signing for your delivery. These are very accurate but in a small number of cases there can be delays due to unforeseen circumstances with couriers. Any delays that we are informed of, will be communicated to you. We are not responsible for any loss of earnings if an item does not arrive on the date we advised.
