Wall is not made good with cement. Probably not plastered around flue inside either...

To original poster: Why not just use either a large company such as BG who can be held accountable for any mistakes, or a small local guy who can provide you with references? Or ask to see some of their work. These are quite basic hints, and I am sure that if you were genuinely concerned...

Don't see what was so good about the classic mate. New fan every 5 years on the FF and a long and tiresome thermocouple change on PP model. Why the hell put the thermocouple at the back?! IMO Ideal's only good boilers are the 18yrs + floorstanders (Mexico, E Type...)

The Biasi Band B condensing boiler is my current "most fitted" model. Its easy to commission, inexpensive, the design is familliar and they are easy to work on. They do not have the excellent interface of the Vaillant ecotec series but I bet that a well installed yet rarely maintained one...

A good rule of thumb I use is that a 15mm pipe can very comfortably serve 3 radiators. So, lets say for example you have 9 radiators: ------------------------------------------------------------------------------- Take your 22mm flow pipe from the boiler, run it whatever way you are doing...

Just fitted a Heatline Band A Solaris boiler and ur spot on about the AAV, I couldn't even get my fingers in to ensure the cap was loose when filling the system! PRV is not much better, and the condensate trap was very hard to remove to fill up after installation. The boiler itself looked...

I would NOT reccommend the Danfoss RX2 or whatever its called. Overcomplicated setting procedure, no heating boost and very ambiguous instructions. I myself am also on the lookout for a decent and easy to use RF stat. I will check out the Salus one above...

I've got one of his Magnaclean powerflushing filters, its basically 2 massive Magnaclean units in series which goes onto the return to your powerflush and it works really well. I always make a point of showing the customer during the powerflush all the crap that comes out stuck to the magnets...

You can't easily buy just the diaphragm for this boiler as they want you to buy the whole diverter valve. I think that the one for the Ariston Eurocombi is the same though, and the larger stockists will sell you that one.

I've seen a Glow-Worm with a very long flue run with rusty spots at almost every flue joint. Water ingress along the outer flue pipe.

Anything on this spreadsheet yet BB? Cheers :D

Ive got a masters degree, and am also CORGI registered... :D Great innit?!

Cheers. Its only for reference so I can use it when quoting...

Can any of you very clever people tell me the maximum flow rates from 15,22 & 28mm copper pipes under 3 bar mains pressure, or tell me where I can find the info? Cheers

Any links to these products?

Sorry, any observations on this pump from Grundfos on the link above? Am going to be doing this work soon so would like to know what installers think of this one. Thanks

Thought it was meant to have energy efficiency info in it? Thats not in a CP12...

Thanks for replies. Have checked Grundfos website and all thats there is the UPA 15-90. The data sheet attached to it states that it only boosts an extra 0.5 - 0.75 bar, and thats not really enough. Corgiman is this the kind of thing you put in...

Hi all. Have a question relating to increasing mains water pressure: In my 1st floor flat we have quite low mains pressure, 1 bar standing, 0.7bar working pressure. I want to install a combi as we have not even a single cupboard and the current airing cupboard would be useful. An old...

Dont think they have room for this new Vaillant in their kitchen, it projects about 0.5m out! Also, a 15 litre store is not much, I think that would be just about enough for 1 minutes use of one of their showers! Anyone got any idea of the volume of water a 15mm pipe can pass in 1...
