It could be scale, but only if the system is knackered in some way, such as pumping over causing the overflow to operate, or a leak in the system. Otherwise, no new water is coming into the system, so no scale can form. Any calcium in the water would have long since disappeared.
The problem could be a slow pump. It could be many things, really. You don't describe the noise.

Vent the baseboad first to remove air.
