It is also necessary to pay attention to what thickness at the wall of such cylinders — it should be in the range of 3 — 20 mm, and the greater the thickness it will be, the higher the level of insulation of the pipe can be obtained and less heat loss. If there is a large length of the pipes of the heating system, then losses can reach up to 50 percent of the initial temperature of the coolant when leaving the boiler.
