    I have this kettle for 2 months. I have to describe everything I know. A flat about 45m2 in a block. Installed in the kitchen. Energy consumption in sleep mode 1.7 W, continuous work: approx. 42-43 in electricity. I do not have experience with other boilers. My 1. Installation of what. I realized for my Installer … He advised to buy this one. 3 years of warranty (after several conditions are met). I bought it through the ditch. When he fires only a quiet buzzing. I do not like it for a long time you have to wait for warm water. Sam-flame – in the furnace (heard from close up) starts around 5s from unscrewing the tap. And warm water is noticeable after 15s. (The point of tap from the furnace 2-2.5, m).

    Also consider the purchase of a electric tray under the bathroom washbasin, in the kitchen. Purchase dishwasher. Unfortunately, there is a non-option for today’s times. The radiators heave quite a ribbon. After a few minutes, they are all warm. About a dozen or so minutes you would have to reach the desired temperature on the radiators. I am nervous with the “plug” of the control panel. It is on a magnet. It is difficult to open it. Neither the handle nor … very impractical. Plans the installation of a room temperature controller. Not enough opinions on the net about him. I bought a little dark. I will have more experiences, I will write more about him. You have your opinions. Let’s help. greetings
