OHA Planning

How to plan an installation

• The correct installation height for radiant strips depends mainly on the height of the room and on other factors such as bridge-cranes, lighting layout, shelving, pipes, electrical cables and so on.
• The intended position of the combustion unit is also important (inside, outside, wall-fitting or on the roof), as well as the fuel supply route to the burner.
• After defining installation height (H) for the strips, please look at the thermal output tables (kW/metre) and establish its length, route, plus the thermal ouput (kW) for the combustion unit supplying the strips. • The system’s flexibility makes the radiant strips adaptable to any routing requirements inside the building, using 90° or 180° curves, as well as both horizontal and vertical 'T' and 'L' branches.

Moreover, depending on heating requirements, the radiant strips can be configured along one or two tubes (Mod. U and Mod. M respectively - see drawings). The route can reach a maximum length of 130 metres in the Mod. U (double tube) version, and 180 metres in the M version (single tube). In this respect, remember that every 90° or 180° curve equals an effective route length of 6 and 12 metres respectively.
