Domestic central heating circuit - obtains maximum benefit from improved insulation by combining individual radiator control with automatic operation

摘要

The central heating system for a house is operated so as to obtain maximum benefit from modern building construction and insulation. The system uses automatic control with an internal and external heat sensor controlling the operation of a boiler installed with its pump, control valve and control unit at low level. The room heaters are distributed in rooms at a higher level, totally enclosed by insulation. The operating system also includes manual control, so that heat is used only in each room as it is occupied. Each radiator has its own supply and return line and control valve which may be operated electronically or manually.
