Description

Hot water heating system

The present invention relates to a hot water heating system, and more particularly, to a hot water heating system having improved thermal efficiency, including a pipe washing apparatus capable of washing a pipe inner diameter.

In general, a hot water heating system used in a device requiring heating and predetermined heat includes a boiler for heating and supplying heating water, a circulation pump for pumping and forcibly circulating heating water supplied from the boiler, and the heating water. It has a circulation structure which includes the distribution part which distributes to each heating part, and the recovery part which collects the heating water via each heating piping.

The series of circulation of the heating water is made by a pipe structure having a predetermined inner diameter and length, and the heating water is semi-permanently circulated in the pipe structure unless a separate operation or a special case.

In such a circulation structure for heating, foreign matter may accumulate on the inner surface of the pipe in the case of prolonged use or for a certain period of time. Such foreign matters may reduce the heating efficiency by narrowing the inside of the pipes, such as slime, rust, scale, and water, and when more foreign matters accumulate, it may cause incapacity due to blockage of the pipe inner diameter. Therefore, as the period of use accumulates, the heating efficiency of the hot water heating system decreases and the hot water heating system breaks down, which leads to a decrease in energy efficiency, resulting in national loss as well as individual users.

In order to solve this problem, the cleaning method using a predetermined washing machine for cleaning the inside of the pipe is used to remove foreign matters inside the pipe, but in this case, there is a risk that the pipe may rupture. In addition, since a separate washing machine is required, the pipe cleaning cannot be performed in a timely manner, so it is also difficult to replace the concentrated water and consume a large cost. In addition, since the operation of the hot water heating system needs to be stopped when the pipe is cleaned, especially in the case of the hot water heating system used in a facility such as a factory, as the operation is stopped, the production line may also be stopped, resulting in enormous economic loss.
