That;s the second time that they;ve been mentioned so merits a larger response. No I wouldn't, I have no need of funding and can provide it myself, I've never understood the people that need to go the dragon's den except maybe for advertising, from what I know, none of the Dragon's went round...

This is air from above existing insulation.

So far the temperature differential has meant that the loft area has yet to lose more heat than is gained, it's a good question though, I'd need a much bigger set of pumps to make a dent in the heat of the air accumulated (and a closed loft hatch), at any point the air out has always been hotter...

An interesting range of responses, Name one that is more economically viable. Air or ground heat exchange units, I've done the maths.

This was me almost 2 years ago http://www.theregister.co.uk/2009/08/27/nhs_spoof_email_xss_flaw/ I found a security hole in the NHS that could have led to mass poisoning. It took an immense effort to be taken seriously and to prove the concept, but basically the UK is more likely to come...

I used to be a physicist, I'm more practical now. Some time ago I had an idea for an instant and cheap way of reducing heating bills without the need for expensive solar panels. I've done the maths on existing installations, and basically apart from the government subsidy it's all overpriced and...

That be courting disaster, I'll be the one with the one foot chisel gouge needing plastering over.

not quite sure how that works with a plug sticking a couple of millimetres from the wall, the former occupants has a habit of not drilling hole deep enough and the still screwing things in so leaving fragmented wall plugs protruding. Oh here's an idea, could the plugs be sanded down ? the wall...

Okay I probably didn't explain something. First I started with red Uno plugs tapped into a 6mm hole these were in the crumbling mortar under the layer of plaster and that was what collapsed. Now I drilled the hole out to the brick underneath using an 8mm bit and a 9mm bit to take the layer of...

Ah ha, and bearing in mind my recent disaster with wall plugs coming out, some are still in, what is the cleanest way to remove a wall plug, I have not only my own but legacy plugs from the former owners, some of which are broken in four directions, with my own new Uno plugs, I found that on...

Okay that title didn't quite come out right. Here's the thing, I look through the screwfix catalogue and find tons of screws for wood, masonry, speciality. But what about bog standard screws for putting into a wall plug ? I found self tappers but that just doesn't seem right, is there a specific...

So does wickes, which is where I got the picture, but the price for what they are is ridiculous. I'm also considering the fischer universal plug from screwfix which is much more reasonable but doesn't include screws. The good thing about rawl wallplugs is that they have the gauge/ mm screw...

Right I tried the original poster's suggestion as it seemed sensible to anchor into the brick. I got round the lip problem by using a slightly bigger drill bit. The downsides, sometimes it didn't hit a brick, the drill went through the mortar between, anchoring is not good here and there's...

Okay so how do I get the lip of the rawl plug past the 20mm of mortar ? without breaking it, no tool I have spring to mind to hammer it through.

Attached should be two pictures. a) the wall. It is brick underneath covered by a thick quite crumbly layer of mortar (sandy stuff anyway) and then very thin plaster on top. The problem is that in various parts of the house this is quite solid enough to let normal wall plug hold, in others it...

It has the depth to get to the brick underneath,.

It was placed outside after I discovered the white oddness to dry it quicker as I figured I'm going to need to take the whole lot off, but it could have been one of the plethora of next door's cats who probably would have no qualms in coming through the open patio doors. That's quite a good...

No I was the first one up this morning, but it is entirely irrelevant now since within the last ten minutes I have just found my children bouncing a cricket ball off the table :evil:

It wasn't damp when I was working on it, but I am wondering if because I had large patio doors open, some form of condensation appeared. The odd thing is that I just checked it and a lot of the varnish has been absorbed into the wood, quite a bit more than I would have expected (based on past...
