    That is an in-floor hot water convector, like a baseboard convector but set into the floor. The grille that should cover it is missing. They are usually installed in front of large expanses of glass, like sliding patio doors.

    The blue device is a balancing valve to regulate the water flow rate. The two small covered tappings on the side of this device are for differential pressure measurement, from which the flow can be calculated.

    aka a flowsetter or circuitsetter. The 2 ports have rubber plugs in them that special needles on the gauge set push through to measure the pressure on both sides to calculate the flow.

    Circuit setters are used to balance the flow on a system that has several (many) branch circuits. A gauge woild be connected to the inlet and the outlet (the caps) of the valve and as the valve was turned, the pressure differential reading would indicate the flow thru the valve. This circuit setter would eliminate the trial and error method of balancing a system.

    After you make that expensive repair and you still have the same problem, What will you check next?

    I think the booties are more protection from what is on the subfloor.
