Andrew - interesting figures ... ten degree rise from a seventeen degree difference - any idea how many m3/hr is going through ... wonder if a lower ...
so perhaps first lift one flagstone for investigations somewhere where you're not walking using the techniques people have suggested and a hacksaw blade to...
Chris, I doubt that the exhaust air entering the Airminder is at 18C - the lounge may be at that temp but there are extract points in other rooms that don't...
PAH! - open themselves, is that all? - you call that a clever bin??? I have a fairly large bin in the kitchen that many years ago I mounted onto one of those...
starter for ten, then : http://www.geekbrief.tv/gbtv-0355-geekbrieftv throw out the projector, have the lid flip open on-command, and you're there, maybe ... ...
Chris Checked the Airminder flow temps this morning: - Fresh air intake: -0.2C - Outlet to house: 9.4C - Return from house: 14.0C - Exhaust: 4.0C So 9.6C gain...
Andrew - many thanks - interesting ! As you say, no idea how they compare, what with data being hard to come by, but they don't seem bad ! Of course, to...
thanks guys, IIUC, if the return temp is too high, the flue gases which by implication, pass by the return pipe, don't condense - so therefore if the return...
Hi all, I didn't get much luck out of google - hoping someone here might be able to help. basically my entrance way is really icy (some on a bit of metal tread...
Rock salt may be 'just salt' - but I suspect you'll find that it's a very impure form of salt. Pure salt would be a white crystalline material; if it contains...
Big bag of table salt, or dishwasher salt should do. Rock salt is supposedly just salt but I suspect there's also a fair amount of "rock" in there too... HTH, ...
we've a couple of rainwater pumps - one is fairly fussy about stuff in the water, the other isn't - so it might be worth checking what sort is installed ? Ours...

Just as a thought, we moved in July into a brand new house, but I don't like the kitchen layout - it just doesn't suit me and I am fussy.... (and I know it) ...
thanks all, big bag of salt it is! and I did think that I could grab a handful of rock salt from one of their bins and stick it in a glass of water to see what...
I noticed that B & Q was selling bagged salt for this purpose at the weekend. Didn't see how much it was, but it was in 20 or 25kg bags for (I suspect) a few...
And a 3kg bag should do 30 sqm - should be plenty! Next problem is water leaking into the house - I'm assuming from snow build up and getting in underneath...
So what is the point of condensing boilers for those that use radiators? I thought rads were spec'd to have a flow of about 77C and a return 11C lower to give...
No, you're not missing anything - it is possible to arrange for condensing on radiator systems - it's quite likely, though,that a survey of installed systems...
I have lifted flagstones that big, slate ones, and I can confirm you are best to leave them where they are if at all possible. Firstly they weigh lots, and...
B&Q and others sell rock salt in 25kg bags. Its less pure than table salt, and much cheaper. I would hope your pumps can deal with some sand/grit maybe via a...
I'll sell you such a beast. I have a PC linked up to temp sensors, and also to zone values, and the on/off switches for my heaters. Any system of tuning things...
And the same to you and yours - and everyone else listening in (on Christmas DAY??? - close to sad!) Nick Nick Laurie PC Repairs nwlaurie@... Skype:...
Likewise Happy Christmas to you all (whilst waiting for Leapfrog software to install for my 3 yr old - who'd have thought Christmas would be so high tech?) ...
Blatant Advert, maybe will save somebody a few quid. I have various heating controls for sale on eBay, grab yourself a bargain. If you want to offer me a deal...
