This question has come up before.

That's the obvious answer, PC, but I notice that this company has taken advertising space in 'Earthmatters' the quarterly journal of Freinds of the Earth. I expect FoE would like to know if the product is rubbish but I would like to have chapter and verse on that before telling them. There is always the possibility that some forms of snake oil actually work.

this has been advertised quite a lot in the uk, I can see quite a few holes in the research they quote.
As I understand it in real use it creates a cold condensation zone at the level of the inserts. however im told that the inserts clog up with salts and muck quite quickly.

So as the air circulates it draws the moisture out of the masonary?
I wonder how you would know if the air circulates
A smoke test??
It's all down to the airflow and the coldbridging?
So moisture would condensate and gather in the ceramic tube?
mmm interesting

Thats how I understand it 'works'.
I have only seen it in one house and that was a VERY damp property, they claimed it worked, but then they also claimed they couldnt smell the damp, and the woodworm wasnt active, and ....

A previous owner had one installed in my son's house, together with plastic windows, cement roughcast, and a concrete floor in the kitchen.
I've no idea whether it works or not. The exterior kitchen walls were found to be wringing wet when the old units were ripped out, but the leaky plumbing that had rotted the units might well have been a contributory factor there. Impossible to do anything about the roughcast, so the walls behind the units are now bare brick.
We fixed a leaking gutter above the breakfast room and lowered the outside ground levels (two skips full of concrete), so there's no more damp.
But that, of course, could well be thanks to the funny things poking out of the wall......?

There have been a lot of complaints to the ASA about adverts for this type of system. There appear to be two companies offering it in the UK and both of them have had adverts referred to the ASA on several occassions. The link below is one of several examples top be found on teh ASA website:

It does seem to me that taking out an ad in a 'respected' journal may be one way of trying to gain respectability for a dubious product. No idea if the journal concerned has any policy regarding from whom they take the money of course!
Just last week I recall we had a thinly-disguised ad for a 'microporous' coating which was advertised in 'listed buildings' or some such mag. It had drawn zillions of enquiries, so it must be good... <IMG SRC="http://www.periodproperty.co.uk/discussing/smileys/smile.gif" BORDER=0 ALT="

The previous owner installed them all around the property unfortunately. Should we try to take them completely and fill the cavity with brick and lime? Or just remove the bit that protrudes from the wall and close the remaining whole with lime?

This is a really early thread and I think the forum software changed around 2005 and it makes no sense.
The Schrijver System seems to be an approach to try to let a bit of water out from nice lime mortared brick walls after you have cement rendered and waterproof painted them. They take a brick out and put magic in there. If you are back to nice breathable lime mortar on the outside it should work way better than the damp proofing invention. Chop it out and bung a brick back in.
It would be interesting to see photos. I've never come across this system in real life.

They have placed them all around the house, the previous owner was struggling with damp issues and didn't have the knowledge to address them properly.

While they are unlikely to fix damp problems, when you have the cement pointing and render and plastic waterproof paint and high external ground levels they might actually be doing a little bit of good. Less good than letting the whole wall evaporate water away, but more good than completely waterproofing the wall. The brown render might well be lime. Anything with green growing on it is much too waterproof.
What are your plans?
What are your plans?
We are planning to lower the ground level around the whole property and install a french drain. We have already discovered some of the airbricks buried under render. We are also planning to remove the plastic paint when the weather gets a bit warmer. Luckily we only have cement render in few places and most of the external walls are just masonry and lime pointing. We want to install internal insulation so we want to make sure we rectify all the external issues first. The biggest issue is the coal hole, the front steps are in terrible shape so we will bite the (very expensive bullet) and replace them. We are also thinking of installing a deep drain on the external side of the coal hole and install a geotextile membrane. The thinking around this latter point is still developing...The house is build on clay soil.

Maybe I should have looked at your other posts first. External walls with lime mortar are brilliant and your approach is good.
I would replace them with brick where they have been inserted into brick. It ought to be possible to find reclaimed bricks that match reasonably well - I've had luck with Facebook marketplace for small quantities of local bricks, otherwise reclamation yards or eBay.
