when i first met the wife, she had her own flat with warm air heating.
the only thing it was fit for was drying clothes. it was brilliant for that.
as a means of heating a flat, it was next to useless.

My first place - a 1970's 3-storey town house - had warm air. It wasn't ~that~ bad. The great thing was really low inertia, so it took very little time to warm up from completely cold.

Unfortunately it was noisy and relatively inefficient - unless you went to great lengths to make the house airtight it had a tendency to blow warm air outside instead of keeping it inside...

May have been ventilation for solid fuel or gas fires in the rooms, no longer needed if there is central heating.

The underfloor space should be vented to the outside by airbricks through the walls with cavity sleeve liners, there should be no need to ventilate the underfloor to the room.

These WILL be from a blown-air central heating system and not anything else.

Still very popular in some countries such as USA and Canada, where wet central heating systems are very unusual.

They often still run on electricity, especially in Canada, where it is still much cheaper than it is here.
