I read somewhere that I will need them if I use the gas heaters that are in the house, but eventually we will move to ducted heating. Can I at least minimise the air flow through them?

No issues with heat loss through vents - DH measured air temperature at floor level, head height & ceiling level & there was plenty of heat at ceiling level.
Our place was f/brick - is yours ?

Doesn't quite sound like a controlled experiment. You need to compare sealed and unsealed with similar weather. See if the heating needs to be left on for longer. Air leaks can result in up to 25% increase in heating bills. We put weather seals in door and windows and lowered our gas bill by about 20%. The vents in old style houses were used in the days of low efficiency fireplaces. You would otherwise poison yourself with carbon monoxide. Not so much an issue now with combustion stoves.

So the vents are there purely to vent the air inside the rooms....not the air between the double bricks?

I would check with a builder but the principle should be the same as a brick veneer structure. The cavity is in continuity with the roof space. It forms the drainage plane for condensation which exits the weep holes through the exteral leaf. retail its around double the price of a similar sized actron/dakin system from memory, They are excellent systems though. But with how builder gouge on AC/heating, you… 4 13773 Old Home Restoration / Renovation Hi, just discovered all these junks left behind under the floor. Could any of these be asbestos?
