A novelty from Willer - a manufacturer of reliable water heating technology from Europe - a flat boiler with two internal stainless steel tanks. Each of the internal tanks contains a "dry" heating element that does not come into contact with water. The use of such heating elements prolongs the service life of the boiler. Each of the heating elements can be switched on separately (for this, there are two power buttons for each heating element on the front part), which reduces the load on the power grid and allows you to use the boiler in an economical mode (when only one heating element is turned on). Including two heating elements at the same time, you can significantly speed up the heating time of the water. The temperature is adjusted by turning the knob located on the front of the boiler body.
