Jaga hydronic trench convectors can be purchased as separate heating elements with mounting brackets or as kits including a steel trench box, plus accessories. The trench box comes uninsulated and this is reflected in the heating outputs listed for the kit option. It is recommended that trench boxes be insulated for improved heating performance. Additional options are listed below including black frames, and trench grills. The standard trench kit listed comes with aluminium frames excluding grills. The heating outputs listed assume maximum 75/65 degree water flow/return temperatures with room at 20 degrees (test standard EN442). For lower 55/45 degree water flow/return temperatures, the heating outputs will be approximately half of those listed below. Note that prices are continually reviewed and may change prior to the new listing. Prices listed below include GST ex Melbourne warehouse. Contact us for supply and installation, pickup or delivery arrangements that may require added freight cost.
