Domestic, hot water ‘radiators’ are easily obstructed; meaning that you can reduce the thermal comfort of your home by allowing boxes, chairs, dogbaskets etc to be placed in contact with them. This effectively stops the necessary airflow over the outer metal surface…and you wonder why it’s suddenly so cold.

On a double radiator, as shown, this can be as much as a 25% reduction in heat output (and slow cooking like this doesn’t help to preserve the integrity of one’s furniture, either)

Today’s invention is a stiff plate (made of insulative material) which fits to the front of any radiator, is held in place by magnets, and which guarantees that a sufficient airflow is maintained, even when obstructions are crammed up against it.
