An apparatus for supporting s a thermal or hydronic expansion tank relative to a hot water heater comprises a rigid bracket adapted to be secured to the tank and to the hot water heater. The bracket provides support for the tank adjacent to the pipe nipple. Means are provided for interconnecting the tank and the bracket for securing the tank to the bracket. In one aspect, the bracket comprises a base, and an end wall at each end of the base. The end walls adapted for engaging and supporting the tank, wherein one of the end walls engages the tank adjacent the pipe nipple and the other of the end walls engages the tank past the midpoint of the length of the tank from the base.

Flow control devices for convector heaters are provided. Such devices may include a casing in the shape of a cylindrical tube having in a first portion thereof, facing in a mounted condition towards the intake conduit of a convector heater, a plurality of first openings and in a second portion thereof, facing in the mounted condition towards the opposite side of the intake conduit, a plurality of second openings, the casing being arranged to be mounted onto the ceiling (S) in such a manner that the first and second openings allow the inside of the casing to be placed into communication with a first space (A1) beneath the ceiling (S) and with a second space (A2) above the ceiling (S), respectively; a closure member in the shape of a cylindrical tube which is mounted within the casing and is axially slidable relative to the latter between a first position, in which it leaves the first openings open and closes the second openings, and a second position, in which it closes the first openings and leaves the second openings open; and actuation elements for controlling the axial sliding movement of the closure member relative to the casing between the first and second position.

A dielectrically insulated secondary tubular flue for mounting inside a water holding tank of a gas-fired water heater is provided to increase the efficiency of the water heater. The secondary tubular flue has opposed tubular end sections and an helical tubular section integrally formed therewith. The tubular end sections each have connecting end sections adapted to form a part of a dielectric connector for securing the secondary tubular flue inside of the water holding tank by the dielectric connectors.

A structural element for a housing structure of a heating device. The structural element is at least essentially, especially completely, developed as a foam part, preferably as a thermoplastic casting foam part. In addition, a housing structure is described, which has a corresponding structural element, preferably at least two corresponding structural elements. Moreover, a heating device is described that includes at least one corresponding structural element and/or a corresponding housing structure. In addition, a method for mounting a corresponding housing structure is described.

An object is to provide a water heater mounting structure for mounting a case to a mounting surface via a support fitting component that is fixed to the mounting surface in a vertical direction. The case houses a burning device. On a back plate of the case, a lock-engagement fitting component is mounted. The lock-engagement fitting component has an upper plate portion and a lower plate portion. The upper plate portion is fixed to the back plate, and the lower plate portion is lock-engageable with the support fitting component from thereabove and has a dimension longer than the support fitting component in the left-right direction. The lower plate portion is lock-engaged with the support fitting component from thereabove to hang and support the case through the lock-engagement fitting component by the support fitting component.
