Criteria for choosing heating equipment on a liquid coolant
When choosing a boiler, you need to give preference to the model that provides a greater range of smooth power modulation from a minimum to a maximum. This is necessary because at different times of the year the amount of heat in order to warm the house, different. The warmer on the street, the lower power the boiler should work, and vice versa. Bad if the boiler has only a constant maximum power value. A little better if it can only work at two steps of power. It’s good if it works in a wide range of smooth power modulation.
The heating system can be organized on the basis of natural or forced circulation. Natural circulation is based on the physical principle of the movement of heated water up without a pump. Therefore, it works regardless of the presence of electricity in the House.
