Out of interest, why woudl I need to fit TRVs if each room (Zone) is on a 2 port and each has a thermostat? Just looked at the Honeywell eco (is thtis what's meant by programable trvs) and it's a good halfway house between full zoning and trvs, it seems...and on 'normal' pipework...anyone...

10mm? and all the manifolds I;ve seen are for plastic push fit...I'd rather go copper all the way if possible...are there copper manifilds out there?

So I was thinking of zoning pretty much each room to give me a fully tailorable heating system future proofed and hopefully as economical as possible. Boiler is on middle floor, ground floor is 4 rooms, middle floor 3 beds two baths and top floor 2 beds. The idea was: Flow and return pipes...

Gents, great conversation regarding the install...so far has helped me hugely with my Texecom 24 install!! Got my panel in, bell box, one keypad (one to go) and two PIRs (6 and an 8XE to go), I've got mostly for Dual Tech grade 3 but one duat tech 360 degree one for the hall as there were a...

Forgot to say...all of it ;-)

well spoke to Telford and they just said yep, 3/4" female thread...when I queried the fact that all the literature and online specs said 22mm cold feed, HW draw and coil he just said well, that's what we fit... So now need to check the internal dia of a male 3/4" fitting.... If that was...

Thanks but know what a thread is ;-) the ribbed inner bore is of the coil, it's not a smooth internal pipe, but a corragated pipe, like a flexipipe...just wondered if this was normal or a high gain coil... The thread will be a 3/4 bsp as inch is about 33mm major diameter (so wouldn't...

inside coil return...ribbed tube - high gain coil?? cylinder... 22 to 15mm reducer in the coil tube...yes i was VERY carefull not to knock it in!! The DHW draw has a decent tube length... ...the rest are around 5 to 6 mm - not enough to get a compression fitting onto...

So just taken delivery of my telford tempest cylinder and it's supposed to have 22mm compression fittings...but there's only 5mm of pipe sticking out of the cylinder and the O/D is 28mm! same for the coil and cold feed and DHW draw off...the inside is threaded but still doesn't seem quite right...

EFL and BAS, you are right...it does say there are alternative ways to comply with the building regs and it says *should* comply, not needs to comply. But as the post above suggests, there's got to be a boomin good argument NOT to follow the British standard or the iee regulations, surely...

Mentions it quite a lot now, and it DOES say it needs to be compliant... http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_P_2013.pdf new version, not the old version...

P.S. is s sub main after the first isolator considdered a CU? My existing ground floor CU is now a sub main and the existing upper floor circuits now terminate in a new submain upstairs. Same 'circuit' but with new wire and faceplates and new RCBOs....

Exactly...I've got a cooker 'circuit' in my house. no idea where the end of the cable goes - certainly no 45amp cooker outlet in my kitchen. As the cable is there and the MCB is there, there's nothing stopping me replacing the cable with new into the location I want, replace the 'missing' 45amp...

I think about five hundred and something...gsm dialer is the most expensive bit, close though to one of the keypads...but had to have a nice looking keypad for the hall! gsm dialler ornly turned up yesterday (bit delayed) so not that advanced with install yet...box in, one keypad up another to...

So that means I can fir my own boiler and if it doesn't blow up, then I can guess I'm competent. Good...

Who fancies ttepping up and quoting for a boiler fit in Southend? Stag, intergas or vailant(or viessmannnn) Will be existing pipework in place ready to accept, invented in place and one zone up and running ready to test. I'll be there so can either be tea boy or your biatch for the...

That's quite funny :-) I started. The thread saying I wanted a wb and it got negative response, with suggestions for stag, vaillant and intergas seeming the popular choices...intergas certainly seems to get good press on other threads... No combos for me thanks...system boiler is about as...
