A quick question - like many others I am trying to maximise our CH efficiency, recently replaced the old boiler with an A rated condenser, system has been thoroughly cleaned and flushed and re balanced and is working well. House is 100 year old semi with suspended floors downstairs with a 3 foot...

UPDATE:- So, after a month where the noise is slightly less, but still too much I eventually found the comparative specs for the 2 wilo pumps, and as I suspected, the max flow rate of the Smart A25 is 2.75 cu mtr/hr, while the Gold RS50 it supposedly replaces has a max flow rate of 3.2cu mt/hr...

The system is 25 years old, over the years it's had 2 replacement pumps, the original Grundfos (@10 years) Wilo (another 10 years) another Wilo that needed a new capacitor @ 4 years, so Wilo have seemed pretty fair in comparison with Grundfoss. The wilo gold 50 I've just replaced is Ok apart...

Is the Wilo Smart A 25 a suitable replacement for the Wilo Gold 50? It was sold to me as such because the Gold 50 was unavailable/discontinued. I can't find any comparison specs and was wondering if this could be the root of my noise problem - see the thread 'Boiler noise is back'

Sorry, wasn't clear enough. :oops: I couldn't get Fernox F1 the day I needed it last April, so used sentinel x100 instead, so I used the sentinel x400 in December. I know not to mix diff manufacturers prods. That's why I've ordered the Fernox silencer to go with the F1 inhibitor...

Sorry for the long post, but it's better to include as much detail as poss. Standard fully pumped Y plan with 9 rads, boiler and HW tank upstairs, system is 25 years old, Glow worm fuel saver Mk2 60kBTU. 8 rads with TRV's. Over the years it's had 2 replacement pumps, the original Grundfos...

Thanks - the reason ? "SWMBO suggested having this cavity insulated to retain heat." TBH I don't think it would make a deal of difference, but to keep the peace I told her I would enquire, so I'm enquiring. I thought that blown cavity insulation was a possibility, but not sure if it was...

1910 terrace, brick built with a narrow gap (approx 1.5" - 2") between ours and next door. The gap is sealed with mortar at the front, lead flashing at roof height front and back (except where both chimney stacks are), but open gap at rear. SWMBO suggested having this cavity insulated to...

It's DrainsAid, they call themselves Yorkshire Water's 'contract Partners'. ie private outsourcing

Just a quick question - having problems with blocked sewer, the contractor for the water authority 'partner' came out, looked down the chamber on our property, said "it's private (not section 24), can't touch it", but didn't look down the street manhole. Had it jetted by private contractor, who...

Does any one know how good (or otherwise) these people:-http://www.buildingcentreofexcellence.co.uk/ are? Or has anyone signed up with them? My daughter's partner is a plasterer (also does other bits of building work) in his first year of business and has been really struggling since...

Thanks Deluks - thought it was someting like that. A

Hmmm, thanks for the replies, but they're not very enlightening. I'm sure it's one of those "if you need to ask, it's not for you" things, but I was intrigued and would like to know. Anyone?

Just seen a job advert for these, and wondered what they were . . .

Update - managed to find the original tin of sealer, and there is a Lithofin product formulated to remove it - Wax off. I also tried a little in an unobtrusve section of the stain, and it seems to remove the white marks! so I'll leave it for a few days to dry properly before doing the rest...

Hopefully someone can advise me. I laid a black chinese slate floor in our kitchen about 3 years ago with considerable help from this forum. It was sealed with a couple of coats of Lithofin MN slate seal, and it has lasted very well indeed. Today, an unfortunate accident with a Galileo...

My neighbour is selling his house, price agreed, surveys done, no problems. Due to complete in a week or so. Out of the blue a building inspector called walked in and demanded that the owner knock holes in the plasterboard cladding on an RSJ. This beam was installed when the wall between the...

Hope this is the right forum - I've searched various others in vain. The question - my daughter has just rented an unfurnished house and there is a space in the kitchen where a 500mm gas cooker was removed. She's going to replace it but there is a wall cupboard (part of a run of them) above...

I'm about to start tiling the kitchen floor, using riven grey slate tiles in various sizes, 300 x 300, 600 x 600, 200 x 400 etc.which are of varying thicknesses according to the size The layout is all planned and originally it was going to be done by a professional, but the schedule has changed...

Hi there - are the clicks high or low frequency? ie 'light' or 'heavy' sounds, Has it got air suspension? We have the same car with this and there are all sorts of pumps (including the ABS etc) and as the pumps go on and off there are lots of clicks, and there appears to be no consistency as...
