Re: Central Heating Wiring Confusing - Return Core Wire Not Connecting to Common Neutral?

Thanks I'm coming to the conclusion that whoever wired it in got a bit confused about what the terminals on the thermostat were. On the HW side, the spare third wire from the cylinder 'stat is connected to the HW-OFF output of the timer. I'm wondering if the installer meant to connect the other (usu...

Central Heating Wiring Confusing - Return Core Wire Not Connecting to Common Neutral?

Our room thermostat might be misbehaving so I've been having a look at it with a view to replacing it. And I've found something I don't understand. It seems like a standard indirect S-plan system. Boiler, pump, dual channel timer and a valve each for CH and HW. The thermostat is a fairly old Honeywe...

Mixer taps

The downstairs cloakroom here has a small sink with a single hole mixer tap with a single lever. Forward and back to turn on and off, left and right for hot and cold. It seems very prone to people not completely shutting it off. It needs to settle exactly in the detent and occasionally doesn't quite...

tiling upside down

I'm about to tile a kitchen wall including the window reveal. I'm fine with the windowsill and sides, but the plan is to tile under the top of the reveal. I've never done this before. Is the adhesive going to hold the tiles up? Or will I have to figure out a way of propping them in place for a while?

Attaching curtain poles to an RSJ

We had French doors installed in a wall with an RSJ lintel above. The wall has been plasterboarded and skimmed and painted and now we're thinking of hanging curtains on 30mm poles. I'm wondering how best to attach the poles. It seems unlikely that the plasterboard alone could take the weight. How ha...

Re: internal doors

[quote="chriscba"]I want to change an internal door in my house, the dimentions of the door frame is 1950mm x 762mm. The doors I've seen are 1981 x 762. I need to take about 25mm off top & bottom, width is ok. Wicks, B&Q ect say you can take a max of 5mm off moulded doors & max...

How to trim kitchen plinths

Given that the best way to lay a laminate floor in a new kitchen is to slide the floor under the plinths--what's the best way of trimming the plinths afterwards? I'm thinking it could be up to half an inch that needs to come off.

I'm not very good with a plane...

Overflow pipe puzzle

Can anyone explain to me why the overflow pipe on a cold water tank (the main cold water tank, not the CH expansion tank) comes in through the wall of the tank and then has a 90 degree downward bend for a couple of inches? It seems to me that this would potentially create a syphon effect if the wate...

Well, I made a bit of an error in my original question. It turns out that the downstairs fan is actually (probably) a mains unit. Although the 2 units have identical fascias (they're from Silavent) the one upstairs is labelled "Low Voltage" (I assume that in context that means 12v) and the...

Bathroom extractor timing

This is more to satisfy my curiosity than anything else. The bathroom has the light and a 12v extractor fan both activated by the pullswitch by the door. The fan appears to be wired from the ceiling light with a three core and earth. Permanent live, switched live (with a brown sleeve on the core) an...

Removing lights

Not sure if this belongs in here or in Decorating, but as it's a bit of electrical kit I'm worrying about I'll try here first We have a brand new kitchen with a bare plaster ceiling. As far as I know it's a plaster skim over plasterboard. Because the ceiling is extremely low (it's a converted garage...

Re: hot water puzzle

[quote]Why do you believe the boiler should stay on for a longer period when only heating the hot water? Are you not getting hot water then? The capacity of the boiler is far in excess of the ability of the tank coil to transfer the energy to the cylinder water so the boiler will only fire for, well...

hot water puzzle

My CH/HW system is a standard Honeywell Y-plan. I had a problem with the 3 port valve recently, I could only get CH if the HW was on. I replaced the valve and that fault has gone away, but it seems that it was masking another little oddity. If I call for HW without the CH on, the boiler (a fairly ne...

Valves: what sort where?

When I look at plumbing fittings, I see several different styles of valve. Stopcocks, gate valves, in-line isolating valves with either a screw head or a small plastic lever, and one other sort with a fairly large brass lever. I was just wondering what different uses each of these have. I know the o...

Hmm. Interesting. I hadn't realised they could get so far apart. I have to change the other rose in that room next; I'll have a look and see what I get between N and E, although I suppose it will vary depending on what else is running in the house. Last time I think the washing machine or tumble dry...
