From my personal experience.
So, the heating boiler is the heart of the heating system. It depends on him how effective and, at the same time, heating will work economically (subject to the correctly selected number of radiators). Since I changed not only the old gas boiler, but also the old gas column, the choice of the boiler type was resolved for me. I decided to put two in one — a double -circuit gas heating boiler. What is it? This is an unit, which heats the room and heats water for household needs. Everything is compiled in one beautiful, modern building that is hung on the wall. All connections are suitable from below, at the top there is a corrugated aluminum pipe to remove combustion products into the chimney.
Preliminary choice I did. But with the final choice I had to tinker. Heating boilers so much that the eyes are scattered. Of course, I wanted to buy a German boiler, the quality is beautiful. I especially liked Wolf boilers, but prices bite. I’ll tell you a secret, and the name of my blog, the secrets of construction and repair, obliges it if there are doubts about the quality of the boiler, ask the sales assistant to remove the boiler body and show it to you from the inside. I have done it many times. Believe me and see for yourself, in a high -quality boiler inside everything is neatly collected and laid; The wires are all fixed with clamps; Water and gas tubes are massive, mainly from copper, they look neat and show with all their appearance that they can be trusted. But it happens on the contrary, you will ask to open the seller of the boiler case, see the filling and covers the horror of chaos and disorder that reigns inside the body and from the sight of miserable water hoses that absolutely do not cause confidence. I don’t know where such boilers produce, but I would not want to buy such a disgrace for myself.
Gas boiler
Gas boiler
In general, I looked at all this and bought myself a gas double -circuit Italian boiler. That’s exactly the same as in the photo. I am satisfied with the work. He has worked for more than half of winter, everything is in order. It works quietly, I can only hear how the pump drives water through the heating system. Compared to the last heating season, a significant saving of gas is already visible. Hot water supply works fine at the boiler. “Smart” automation itself regulates the intensity of the burner, depending on the load. The temperature in the heating system can be adjusted with an accuracy of several degrees. I plan to buy a programmer for this boiler in the near future. This is such an electronic device with which you can set the temperature in the room by time. For example, everyone went to work at 8 in the morning — from that time on the boiler reduces the temperature in the room to a given value, saves gas. And closer to evening, at a pre -tuned time, the boiler smoothly raises the temperature to the desired. Convenient, economical that, taking into account the growth of gas prices, it is very relevant.
These are the secrets of construction and repair today today.
Good luck and warmth in the house.
