hi, just fixed my dryer with using 'sticks like ****' by glueing the extractor fan back on to the motor shaft. then realised that you could actually buy new fans and clips to secure them (search for bosch wta2000 spares) then learnt that the Bosch wta2000 is actually made by a company...

hi all, thanks for your help on a previous post which has helped me determine that my house has a single pipe system. i'm fitting new rads throughout and some of the older ones did not get hot (possibly they were on the end of the ring) and want some advice about this please. 1) having...

thanks tamz that all makes sense except the gravity part, what incentive is there for hot water to rise into the radiator and the cold water that's already in the rad to drain out? the hot water in the pipe will be the same temp at both connections to the rad. or is the fractional difference...

OK - half way there! the upstairs has the rads in series and each rad has a pipe as in the above photo which connects across the inlet / outlet of the rad. the suspicious looking extra pipe on the right side of the photo (heading down on the pic) actually is a tee to feed the rad in the...

thanks for your help on this guys. on the left and right of the of the pic you will see the vertical pipes which join to the rad. further left than the left side rad feed pipe, there is another underfloor pipe (going down to bottom of the picture) which has travelled the length of the room...

obviously! what i mean is there are two copper pipes under the floor heading towards each rad from the central heating system. each of these pipes goes to one end of each rad but the pair of pipes are 'shorted out' under the floor before they reach each rad so if the shorting pipe was not there...

looked again and there are 2 pipes going to each rad which i assumed to be supply and return. every rad however seems to have a 'sorting' pipe directly across it! if they were in series why are there 2 pipes to each rad?

im tempted to squash the pipe which is in parallel with tha rads is this bad idea?

so the rads are essentially in series rather than parallel? if this is so why would anyone do this - just to save copper pipe? would this also expalin why its difficult to balance the system?

what does that mean?

ah i see - but why would water want to flow through the rad under normal circumstances? would it not be sensible to have one global pipe perhaps with a pressure relief valve? to provide this service why lots of them?

hi guys, in the middle of a big renovation of my house and fitting new trendy rads but have a strange issue. i've seen this when replacing radiators downstairs and wondered about it then but now its got me confused. there are two pipes going to the rad as usual; supply and return but...

its a galvanised water tank, why do i need to worry about the float valve? not enough space at the sides to get a drill in :(
