Powerflush took all day, as mentioned, each rad done separtely by isolating all the other rads and then reversing the flow and positive flow through the boiler to clear it....all in 2022. Other questions already answered above.

Thanks for the reply, as per my original post, the boiler is a Viessman 111-w vitodens boiler. We got the error msg only on HW mode as the temp increases to 90+ degrees and cuts out. At the moment its not doing it because I ran the MC3+.

No, when we power flushed it in 2022 we had filthy black water come out. this was the first time we ever flushed the system. all rads were hot after that. Viessmann have already been around, they said powerflush it, which I have.

So the last proper professional powerflush was done in April 2022, each rad flushed from the kitchen by closing each rad valve. ATTQ - the reason for wanting or needing to do the flush is that around Feb each year I'm getting F2 errors and the boiler hot water temp reaches 90-100 degree...

is it safe for me to open a drain valve on my radiator system whilst at the same time opening the filler loop and letting the boiler pump operate so as to replicate a powerflush? I've spent nearly £800 over 3 years doing a professional powerflush but I still get problem with F2 error on my...

I'm having to come back to this same issue again because despite having spent nearly £600 to powerflush my boiler system shortly after my original post in March 2022, I still have problem after spending a more money to get someone to put some MC3 cleaner in my Magnaclean Pro 2 filter...

Thanks for the replies. I should have perhaps made more clear, I meant replacing the whole unit housing and tube not just replace one long fluorescent glass tube for an LED one. Was looking at Aurora at about £60. I also think 4000k is a nice balance in colour rather than a pure clinical...

Im looking to replace my existing florescent tube lights for the corridores and toilet and kitchenette areas of my dental practice. Any suggestions on the make and model of some LED tube lights, ideally with sensor too. Should I avoid microwave sensors as someone told me that they can...

Without looking at my lease again, which was only negotiated two months ago, it is a full repairing lease which means I have to cover everything internally. I might check with the landlord in the coming months If it’s going to cost more than a few hundred pounds, which it clearly sounds alike...

Good point, will check thanks. From a technical point, what generally goes wrong with these windows in this way?

Can see the string / rope has snapped on the right side

We have what I believe is a sash window (the sliding up and down wooden ones), after taking up a tenancy on a first floor office. The window doesn't stay up and is quite heavy so have to jam something underneath to keep it open. Looks as if a rope on the right side has torn away. What is the...

wow selling an old technology box at the price, good luck, even with the 39% off. I ended up buying off amazon a refurb for £32 with prime delivery for the 500gb version. I figure to buy it without the hard drive is as expensive if not more or the box looks ancient...

Point taken, but it's understood what he mean i.e. free to air channels which are also on Freeview / Freesat.

Nope, but I like to watch the telly too :-)
