New builds are now so efficient, you barely need any heating on
So efficient I've had solar film fitted to the sarf facing windows, otherwise its unbearable in the summer without the AC.

Noticed condensation on the inside of the kitchen / living room / bedroom windows post-shower for the first time yesterday.
Still airing the flat when I get back but the duration the windows are open is ever-dwindling.
Failed spectacularly to sort the leaking boiler over the summer so might just try to push through the winter with it as-is; not sure if the increased load of the heating will exacerbate the situation.
Probably also ought to give it a test soon as it's not been on at all since I moved in, the owners did have it set low before that although the place is pretty efficient so it probably wasn't on much during the spring.
Some curtains in the living room would probably help too; although this would require effort and choices; neither of which I'm at all adept at..
Thanks - the condensation comment was more of an observation than a complaint.Heating the flat will definitely help the situation, no heating, high humidity = condensation and black spot mould. Also make sure if your bathroom has a window you always open it when having a shower as extractors never seem to work that well. If the flat is not particularly well ventilated then definitely consider investing in a decent dehumidifier, they really do make a difference.

I have found the odd bit of mould in the bathroom but this was because I'd got out of the habit of leaving the extractor fan on (little bit on the ceiling) or just not staying on top of cleaning the areas around the bath where water accumulates from the shower. Now everything gets mercilessly hosed with vinegar weekly it's no longer an issue - at least for now.
The bathroom has no windows but the fan seems pretty good and all walls are internal so it doesn't see a huge temperature differential. Since I live alone I also tend to shower with the door open, allowing some moist air into the rest of the living area which (mould aside) is welcome as my skin's constantly dry and I struggle especially in the winter so keeping the humidity at a reasonable level is preferable.
Will certainly look into a dehumidifier it mould becomes a problem - although hopefully this won't be the case
In other news I fired the heating up this morning just as a test - results were good; banged that 'stat up to 25 to be sure it'd come on (it clicking in at around 20 degrees) and all the rads heated up rapidly / evenly upon a quick cursory inspection. Not that it was cold to begin with but it only took a few minutes for the flat to become uncomfortably warm - necessitating the opening of windows.. so that bodes well for the colder months.
I'd like to bleed the rads (a source I found suggested this was relevant to the leaking boiler issue although I can't see how) however only the heated towel rail in the bathroom actually has an obvious bleed valve; the rest appear blanked or perhaps need to have the whole plug turned to open the system up to atmospheric.
Any thoughts on this would be welcome![]()
Thanks and no - it absolutely needs looking at for the leak but as usual I'm paralised by indecision and mistrust of tradesmen.... did seek a recommendation off a mate but it turned out the guy he was initially happy with ended up screwing him so that's done nowt for my confidence..Have you had the boiler serviced? You've recently bought the place haven't you?
I ask as in my house the boiler gave up about 4 months after moving in, during a very cold spell in Dec. I was able to get a new one fitted at short notice but I feel it might have been spotted earlier if I had it serviced.
Cheers - didn't know that. There are no obvious issues that suggest it requires bleeding (other than the spurious suggestion that it would help with the leak) so perhaps I'll leave it aloneIt's only really 'open'* systems that need bleeding, modern 'pressurised' systems don't need it apart from initial commisioning of a new boiler or radiator.

Now there's no guarantee of course that whoever you choose is still not an idiot, bit thats probably the safest place to start.
It might not be the cheapest but I decided to get a British Gas service plan in place, costs around £20 p/month.
