We are a flat in the middle of a development. 3rd floor, surrounded on all sides but one (windows and balcony side). So I guess we are a shared flue of some kind and maybe there are permission issues with the leaseholders about re-routing to external walls for individual flats? Re getting...

This sounds right but I'm only going on what my gas fitter told me. All I know is that we can't have a gas combi for some reason and that after erp 2015 we will only be able to have electric.

Hi, erp 2015 is coming up 26th Sept and the legislation means that if (when?!) my current heat only boiler and water tank set up (an old Thorn) goes pop we will not be able to fit a new gas boiler due to the flue and will be forced to go electric. We cannot get a gas combi due to the flue. So...

Yes it was nothing scientific. I just took a 1litre jug and timed how long it took to fill! Results will therefore I guess be mostly meaningless but here goes: Hot tap only on full: 2 sec=30l/min of water too hot to touch- I think this is more than the stats for this boiler says. 5 sec...

The hot water of the Atag is great. We have 4 bar water pressure and I can turn the hot tap to its fullest and it will produce a very strong flow water that is too hot to touch! Our shower is also a good pressure. I'll test two outlets for you asap and let you know but the hot flow is so...

Well the honeywell ones seem quieter. The hissing seemed to be the cheaper basc danfoss 212's. Shame about the annoying ugly green button on the honeywells!

It seems a lot better now we swopped to honeywell trv's. There are still a few trickling noises but no/much less hissing.

Hi, I have another thread here (//www.diynot.com/diy/threads/noisy-hissing-radiators-hissing-noise-in-new-rads-or-trvs.420484/#3265881) which explains why Im asking. I'm not trying to be greedy or selfish starting new threads but I thought this new thread with its title would be a better...

Hi John, no it doesn't stop if you turn it higher. It makes the noise until it is up to heat anf only stops if the rad stops, if the rad is continuing to be hot the noise remains.

Twgas: thanks. I will ask my installer about this. JohnD: if the trv is turned so that the radiator shuts down then the noise stops yes. So it makes noise when rad is "on" but not "off". I've asked the installer to try another brand of trv. He says on he will do but he used Drayton RT212...

Hi, I've done a search and read some around the subject but unsure how to proceed. We've just had a new boiler and new rads fitted (except one in the bedroom which was already newly fitted within the year). The new rads, especially a vertical one in lounge and towel rail in bathroom all make...

Great. I went with atag in the end. Tough to choose but heard Intergas doesn't like hard water and liked the idea of extra hot water flow and included heat recovery in the A325ECX

I asked them how they get their "default values" and this was the reply: passed me your enquiry about the significance of the term ‘default value’ in the context of hot water energy efficiency in the PCDB. The PCDB exists primarily to provide information for SAP assessors rather than as a...

well yes I would trust the SEDBUK to be impartial but they said they used "default values" god knows what they are or where they got them but they seem unlikely to be correct.

Well however long it takes with a combi son't it take longer if you run out of Hot Water and have to reheat your tank? How long does it take to reheat an average HW tank? TBH though I think my choice to switch to a combi has been dictated by my wife and space considerations and I just have to...
