A drainage tray for collecting condensate from a heat pump is disclosed, where the heat pump (3) being adapted to be mounted on a support (4) being mountable to at least one supporting structure to carry the weight of the heat pump (2) and the support (4) wherein the tray (2) comprises a peripheral and preferably inclined edge portion (7) defining a central recessed tray portion (8) configured to collect condensate, wherein the tray further comprises a condensate outlet (9) for removing the condensate from the tray (2).

A fluid storage apparatus includes a guiding mechanism that linearly guides a flexible container in accordance with expansion and contraction of the flexible container. The guiding mechanism includes a guiding column that is disposed adjacent to the flexible container and that extends linearly and a slider that has a guiding hole, in which the guiding column is inserted, and that is formed on an upper edge portion of the flexible container.

A vent pipe cover for providing a water tight flashing seal around pipes penetrating from the exterior wall of a structure. The vent pipe cover generally includes a sealing unit adapted to be secured around vent pipe extending from a building. The sealing unit includes a central gasket which seals the gap between the pipe and the building and an outer flange adapted to receiver fasteners for securing the sealing unit to the building. A trim unit is also included which may be slidably connected to the sealing unit to cover the outer flange and provide a finished look.

A manifold (15) comprising a flow chamber (35) for receiving flow heat exchange water from respective heat sources (3, 5, 7) through first inlet ports (47, 48) and from which the flow heat exchange water is delivered to heat exchange circuits (8, 9) through flow ports (57, 58). A return chamber (36) in the manifold (15) for receiving return heat exchange water from the heat exchange circuits (8, 9) through return ports (57, 58), and from which the return heat exchange water is returned to some of the heat sources (3, 5, 7) through first outlet ports (53, 54). A bypass chamber (37) located in the manifold (15) between the flow chamber (35) and the return chamber (36) receives flow water from the flow chamber (35), which has not been drawn off by the heat exchange circuits (8, 9), through a communicating passageway (40). Heat exchange water from the bypass chamber (37) is returned through second outlet ports (55, 56) to others of the heat sources (3, 5, 7).

A heating system includes a first pipe portion configured to connect to piping that returns water from a heat exchanger in a building back to a boiler in the building. A longitudinal axis of the first pipe portion can extend vertically. A second pipe portion can have a first end, a second end, and a longitudinal axis extending therebetween. The first end of the second pipe portion can be configured to connect to piping that supplies water to the heat exchanger. The second end of the second pipe portion can be configured to connect to the second end of the first pipe portion. The longitudinal axis of the second pipe portion can extend parallel to the longitudinal axis of the first pipe portion. The second pipe portion can be spaced-apart from the first pipe portion. The system can be in the form of an installation kit for a heating appliance.

A hot water apparatus includes a heat exchanger and a housing. A case has a circumferential wall portion, a lower opening, and a flange portion. A case has a flange portion, a circumferential wall portion, and an upper opening. The circumferential wall portion includes a downwardly-extending wall portion inserted into the inside of the circumferential wall portion through the upper opening. In a state where the downwardly-extending wall portion is arranged inside the circumferential wall portion, the lower opening is located below an upper surface of the flange portion.
