Basic DIY questions?

Been bugging me for a while. What is this for. I can turn it on and it lights up but as far as I know it does nothing. I have never used it and have successfully had hot water for showers, washing up etc since moving in but when I’ve had an occasional bath the hot water hasn’t lasted all that long.

I have a combi boiler and what appears to be an empty water tank in loft. So I thought the switch did nothing but now I’m wondering if it would boost hot water (or should I be increasing the flow temp on the boiler)
Is it nearish the sink? Might be for a future instant water heater thingy. Possibly an outlet under the sink.
Maybe
 
Or, if the combi has replaced a cylinder+system boiler, and if the cylinder was fairly local (other side of wall?), might be for the ex- immersion
^^^ This
When we moved in we had a open pressure CH boiler on the outside kitchen wall and a switch next to that turned the immersion heater in the tank on. When the wall was knocked down which necessitated the removal of said boiler, the combi boiler that replaced it went into the airing cupboard upstairs replacing the hot water cylinder. The plumber who fitted the boiler re-used the immersion cable to power the boiler (the switch disappeared along with the entire wall)
We still have the expansion tank in the attic (now disconnected and pushed to the back since it was too big to fit through the loft hatch.
Immersion heaters are generally on a separate circuit so have a look in your fusebox and see if you have a breaker labelled immersion heater, you will probably find it is just powering this switch now.

I don’t know obviously but assume it was previously a cylinder + system setup. I’d have the thought the cylinder was in my airing cupboard upstairs as that’s where the space is rather in the kitchen but honestly no idea.

So looks like it’s just a switch that does nothing. Thanks :)

Your cylinder would have been upstairs in the airing cupboard ours was and the switch for it was in the kitchen so a good 20ft or so away. It's apparently illegal (or against building reqs at least) to have a switch or plug that is reachable from the sink so our immersion heater switch was about 6 or 7ft away and yours is on the other side of the room. The chief builder we hired had a Olympic gold medal in Ceaseless Talking so I learnt quite a bit about building regs whether I wanted to or not. The airing cupboard was an ideal place to put a Combi boiler since there was already central heating pipes, water pipes and an electric cable to it so they only had to add a gas pipe, a condensate pipe and cut a hole for the flue.

My boiler is downstairs in kitchen next to sink and external wall. My airing cupboard is not near an external wall so no flue possible there.

Anyway that’s figured it out I’ll take a look at the fuse box when I remember
 
Looks like a switch for an immersion heater to me, probably was one back in the day that was replaced by the combi-boiler.

EDIT: Sorry, just realised that the thread had gone onto the next page and hadn't yet read all the responses... :facepalm:

My original boiler was downstairs in the kitchen about 4ft from the sink which was under the window. Whoever replaced your boiler probably just stuck it in the same place as the old one since that would have been easiest.
My builders had to get a bit more creative since the boiler was on a wall that was going to be knocked out and they couldn't really just suspend it there in mid-air (though that would have been a cool conversation piece I guess)

We have the same ours is nothing. Combi boiler so presumably old immersion
 
Any thoughts on what is causing my leaking kitchen roof? Specifically it occurs when we have really heavy rain with lots of wind. The construction of the kitchen roof is felt which is in good condition. Current theory is water is getting behind the frame of the window or it is coming from higher up. The seal around the window looks ok though to my untrained eye. Really need to sort this as kitchen ceiling now has unsightly water makers.

Cheers.
Can't see where the chicken wire is.

There is some felt "flashing" missing at the R side of roof which could cause damp in that corner. Is that felt between the wall and top of roof?

How long has felt being on? Felt doesn't last all that long so it may need replacing. Problem with felt roofs is that water can get in and then track under the felt before coming out somewhere else so not obvious where the problem is. :(

I think the felt has been on for some time - the red stuff I had put on thinking that's where the water was getting in but my working theory is it getting in higher up and running downhill ending up dripping inside by the kitchen window.

Right under the main roof? :eek:

That's for ventilation for the loft but doesn't need to be as open as that. Do you have any damp problems in the upstairs room?

As your damp appears to be restricted to the top and bottom of the kitchen roof the leaks are probably localised otherwise I would have thought there would be more damp patches across the whole ceiling.
 
This flashing, which you say you did yourself?

Screenshot 2023-04-19 at 22.49.20.jpg

There is the red coloured bit; to the left of that there is something else, which I imagine is what it was all like before you did your repair: what is it exactly?

Generally in this kind of situation, ideally there would be the roofing (felt in this case) and where it meets the wall it would bend upwards and tuck behind some proper flashing, most likely lead. That lead flashing should go into a kind of deep slot in the brickwork behind the render. So any water running down the surface of the render, or even behind the render, gets directed outwards, down the outside of the lead flashing, then onto the roofing and away.

The alternative is some kind of drip detail at the bottom of the render; it might be a kind of metal angle a bit like a plasterer's stop bead, again the idea would be that it would catch any water running down the surface of the wall and shed it away from the wall, and not let it get near any kind of top edge of the felt roofing where it's folded up the wall.

The "repair" job doesn't do either of these things - it looks like the felt is folded up the wall and probably not really attached to it properly, then there is a kind of a messy bottom edge of the render, then the gap inbetween is filled with some kind of mastic or something. This is pretty much bound to fail, at least after a while, because even though they might not be obvious there are probably lots of tiny gaps between the render and the mastic, and the felt and the mastic, and water can find its way along these, either by capilliary action or driven by wind.

You say the problem occurs when it's windy - never underestimate the power of the wind to force rainwater uphill, through tiny cracks and so on.

Therefore, to me it's plausible that on a window day, water gets blasted up the slope of the roof and finds it way in through the dodgy repair job.

Like WouldBe says, once water gets under a felt roof it can track along quite a way and you might see damp appearing quite distant from the place the water's actually getting in.

I might be wrong, can't say for sure this junction is where the problem is, but it's one of the things I'd be taking a look at.
 
Just subscribing to thread, cos I can feel it in my bones that I’m going to be needing DIY advice any year now.

I don’t know shit.
 
Apologies for any snooker/pool nerdery from me btw.
Although snooker is the most tedious game in the world to watch second only to golf, that doesn't stop me trying to sink balls on a regular basis :D
 
Unfortunately no easy access to snooker tables round here atm, play pool (English 8 Ball) regularly though :)

Used to belong to a snooker club when I lived over in West Norwood and played snooker and both English and US Pool as they had all 3 types of table, that was the golden years. Also bar til ridiculous o'clock, practically lived in there for a while.
