An air purifying system includes one or more air permeable photocatalytic elements defining a core cavity having a sealed top end and an open bottom end. A sealed air flow path ensures that air travels from an outside of the core cavity, through the one or more photocatalytic elements, into the core cavity, to be expelled through the open bottom end. A UV radiation source disposed within the core cavity irradiates air travelling along the sealed flow path and an interior of the one or more photocatalytic elements. Each photocatalytic element is manufactured using a substrate, that is conductive of and transparent to UV radiation, coated with a photocatalyst. A non-photocatalytically active material is initially coated on the substrate and is then converted to a photocatalyst by calcination.

A work bench, mountable on a pair of vertical elongate members, adapted to be mounted on a wall. The work bench can be collapsed from an extended position to a stowed position coplanar with the elongate members. The elongate members each have longitudinally spaced notches. A bracing member is provided with a pair of trunnion members that extend from the bracing member and are releasably pivotably coupled to a pair of notches in respective of the pair of elongate members; the bracing member further having a distal end for releasably engaging the working surface of the work bench. When in the extended position, the distal end of the bracing member releasably engages the work bench to support the work bench; when in the collapsed position the work bench overlays the bracing assembly.

A heater comprises an enhanced-surface area heat transfer vessel which is situated co-axially in a hot flue gas plenum. The plenum is formed by dual-wall heating jacket. Liquid flowing through the jacket is heated co-currently by the flue gas before the preheated liquid is conducted to the top of the vessel for countercurrent heat exchange therein before discharge from the bottom of the vessel. Hot flue gas flowing through the plenum is directed circumferentially by one or more spaced and perforated ring plates placed across the plenum annulus between the jacket and the vessel. Aluminum construction of the vessel and jacket with protective coatings contribute to a lightweight heater for either floor or even wall mounting. The heater is conveniently implemented in a hydronic heating system, a potable hot water system or a combination of both.
