An apparatus for maintaining the temperature of material contained in fluid conveying devices. The apparatus may include a cover that encloses a fluid conveying device and a drain channel that is supported upon a surface, such as a concrete slab. Heating elements may be included within the drain channel or enclosure to maintain the temperature of the material and the fluid conveying devices surrounding the material above a predetermined setpoint. The drain channel may employ a suitable valve or valves to facilitate the removal of discharged material from the enclosure in applications where the fluid conveying device discharges material to the atmosphere. Adjustable forms are included that support the drain channel and provide the perimeter for a concrete slab.
