I can't be 100% without a relay part number or datasheet -- but most commonly, that type of specification would be 8A switching a resistive load (say a small heating element), and 3A switching an inductive load (say a fan motor). Solid-state inputs and relay coils generally don't draw enough current to be a problem.

By making sure of the space behind, ...

The hot water baseboard heating will be heating the room mostly due to radiative surfaces that conduct the heat out of the water pipe and into the air of the room. For this to work there needs to be allowance for the air in the room to naturally move from the heater area and into the room. If you cover it up it will not be heating the room in the same way. ...
