    Solid and functional Italian gas boiler
    29 February 2016 
    Bought for installation in a small private dental clinic. The cunning system of quick hot water supply bribed, because the hands of doctors and medical staff have to be washed constantly.
    The boiler is powerful enough to heat 250 square meters of the clinic area and at the same time provide 10-15 liters of hot water per minute. Gives hot water right away. It has a built-in 2-liter mini-boiler, which stores a supply of constantly heated coolant. When someone opens a tap, the water is first heated by the hot coolant from the boiler, and in parallel, the water starts heating in the boiler's plate heat exchanger. It turns out that there is always hot water and, what is especially valuable, there is immediately. High efficiency of gas use, which is achieved due to the electronic control of the burner flame. The design uses well-known components. It has no problems with traction, this problem has already been solved by a turbofan. A full chimney, respectively, is also not needed. In addition to the above, the boiler has all the necessary protection for all occasions. So much about anything, but the designers worried about safety. The boiler is very simple and convenient to control, but after the external temperature sensor is connected, this should be done much less frequently. Most of the time, automation does the job just fine.
    Expensive, but I think that in 2-3 years it will justify its price due to its high energy efficiency.
