Provided is a hot-water circulation heating system, wherein a circulation system unit that connects to a radiator is stored compactly inside a heater unit box to enable easy transportation and installation, which increases flexibility in terms of the design and the configuration of the hot-water circulation heating system. An angular column-shaped heater unit box (1) has lids (1U, 1D) on both ends to allow the heater unit box (1) to be opened and closed freely, and has a hot-water circulation function unit integrated by connecting an air separation pressure tank (2), a circulation pump (3) and a pipe heater (4) with pipes via ball valves (6A, 6B, 6C) and T-joints (7, 7A). The heater unit box (1) can be placed adjacent to a hot-water circulation radiator (HR) vertically or laterally. |
