Could an industrial sander not suffice because at most its just 6mm? Using a grinder worries me about potential disruption of the ufh system.

So we had our appointed plasterer/screeder screed our Polypipe underfloor heated floor in our new extension on Friday and despite asking time again about how he would check the levels and requesting that he leave a clearance of 35mm below the threshold of our bifold doors, he has messed up...

So we ended up going with a Vaillant 630 coupled with a Unistor 630. I plan on getting the new fandangled Evohome system when it is released next year but my question is do we still need the Vaillant controls such as the VR65 and what not?

Oh and excuse my ignorance by does the Glow-worm incorporate a combination boiler? I thought they generally weren't recommended for larger properties? Any other suggestions for an unvented cylinder? Finally, I realise this might be a stupid question but is a larger cylinder generally more...

So can a softener be installed into this setup without any problems? I'm really keen on installing Evohome and the TRVs. With a Vaillant boiler, does that makes sense? No one recommending the OSO I see. What are the advantages of having a separate expansion vessel?

Hi all. Please excuse this novice. I've been searching these forums for advice on new cylinders but am still nonethewiser! We are currently having a side return extension built onto our terraced house in London. The extension will incorporate a bigger kitchen, new cloakroom and downstairs...

I can understand the logic of the plenum system however we have now decided that cooling is no longer a necessity and since the fan will be running at intermittent intervals it won't be as effective. Good ventilation is now the only requirement. We'll depend upon the (thermal masses, stone...

10 - 18 degrees or so.

Potatoes, onions, flour, rice, condiments, spices, store cupboard items. Basically everything which wouldn't ordinarily be stored in a fridge.

That's my concern. While I have your attention John, lack of insulation under the concrete floor slab - will that have a significant impact on ambient temperature? There is a consideration to perhaps build the room lower into the ground. Thanks for all the advice by the way.

Just to be clear, it is fine for air to be drawn in at high level and extracted at low level? This is going to sound crazy but would there be any point in having both systems in place? I ask this because the length of duct at floor level will be approximately 3 metres.

Incidentally, that small corner of the room will receive no insulation under its concrete base unlike the rest of the extension. Would this make any significant difference to the ambient temperature of the room? We were considering lowering the floor level in the pantry too.

So in general, is a positive pressure system a more efficient way of ventilating (and perhaps cooling) a room than a negative one? Out of curiosity, does anyone know what the smallest and most cost effective airconditioning device that is available on the market today?

I'm assuming you would need another fan at floor level to exhaust the air? How else would it be encouraged to leave the room?

This Guardian piece (the first question) describes what we want to achieve: http://www.theguardian.com/lifeandstyle/2007/aug/11/shopping.homes As an aside, 150mm thickness of insulation seems a bit of overkill don't you think?
