Opening up a fireplace

Ok so this is the 4th fireplace I've opened up in this house in the last 6 months. The others were fairly straightforward but this one contained a few surprises. Pipes and electrical cables. I'm wondering if anyone can help identify what they are? I'm guessing it might have had a small log burner in there and the pipes might be a back boiler? The electrical cable has a plastic mount with a wire sticking out, it says 'Heating'. I can't make out the other words. Any ideas?

Left of the fireplace it might have a switched fuse spur that twin and earth comes from.
it goes through metal conduit, do check if no then you need to test it if it’s live.
 
Do you think it looks like it had a gas fire in there? I'm a bit concerned by the pipes being taped up. Looks a bit of a cowboy job. I'm trying to work out if they're water or gas pipes?

As for the pipes you do need to get it tested, likely it could be gas. it does look untidy workmanship I must say.
 
The sheet material that the flue goes through looks like asbestos.
I hope not! It looks like the same boarding I had in a previous house with a log burner. There is a log burner in another room but that's been fitted in the last 3 years and the boarding doesn't appear to be removable.
 
There was a fire and back boiler in there by the looks of it once upon a time.

The pipe with tape on it. If you remove the tape, it's probably a compression elbow that connected to that bit of pipe coming out the wall which is flush, looks like the olive is still on it.

That electrical connection will be what went to the old fire/back boiler.

I would bet good money both are dead, but get them checked yourself 👍👍
 
Oh, and the boarding will likely be asbestos, however with the age of the flue liner, it could well be Cement board.
 
All looks easy to me. just plasterboard it back up.

it looks like it was originally an old back box fire. ie a metal box behind a coal fire that heated the hot water up to the hot water cistern tank. then it looks like that old fire was removed and some sort of gas fire installed. flue liner, the electric could have been ignition. they probably removed the back box at same time

Pretty sure it's cement board. This part of the house is a more modern extension albeit possibly as far back as the 50's or 60's

I'm planning on putting one of these and a hearth in place just for decoration and ventilation to stop damp problems https://www.flames.co.uk/cast-iron-fireplaces/carron-toulouse-cast-iron-fireplace.html I could ignore all that stuff as though I never saw it but would like to not have nightmares
 
Very common to have power in gas fires to provide electronic ignition. OR it could of been an electric fire at some point.

Now gas - I wouldnt mess with that. Get a pro in to check if its connected still and 'bunged off'. If you want another gas fire then you do have to get someone corgi registered (no its nothing to do with dogs).

More likely than not that power cable will be fed from a fuse spur next to a local socket, or it may be 'taken' directly off the back of a nearby socket so could be live. If you cant locate where it comes from then it may be a bloody junction box hidden under the floor.

Seriously - be careful. Send the wife in to check if the wire is live.

if it was me because I would be fitting a log burner, the twin and earth I would remove it, check if it’s live with a multimeter or a electrical screwdriver, it should be on a isolated switch if not it must be coming from a junction box. you need find the other end of that cable and disconnect it.
I would have no choice to call a plumber to get that pipe checked water or gas and have it redirected away from the inside of the fireplace.
That board does look like a cement board in the photo.
What ever was there before doesn’t matter it’s what your fitting in it’s place now ? I wouldn’t leave that pipe inside the fireplace just in case a real fire was fitted.
please get a plumber in and get it checked and redirected out of that fireplace.

Good luck
 
If you ever get damp walls coming down from your chimney and it’s the original Victorian chimney don’t make the mistake I was making and get the chimney replaced with double lead trays, I had my rental chimneys repaired/repointed/reflashed/coated a couple of times and was still having problems with damp walls. I had it checked out and was told the bricks and mortar had reached saturation point and was just letting water down. When they took the old chimneys down they were just falling apart I was amazed the wind hadn’t blown them down. Not had any damp since, probably the first time in God knows how many years.
My son lives next door and I couldn’t work out why he wasn’t having damp walls if the chimney was knackered, then we found rubber under the plaster😡
I guess closing fireplaces up and not getting them hot with a fire doesn’t help as this would help dry them out.

Thanks. I'm only fitting a fireplace for decoration and to vent the chimney breast. It won't be a working fireplace. Whoever closed this one up didn't vent it at all.

I have found problems with damp where they've closed up the other fireplaces and not vented them adequately. And then on top of that some idiot has plastered right down to the ground without leaving a gap where it meets the floor so the plaster is wicking up moisture. Oh and all the bloody TV aerial cables going breaching the cavity walls too. I'm hoping this is the last room to fix now.
 
Where is it you live? I had a feeling it was Cheshire way, but your location on the forum shows Conwy.

I'm a gas eng for the emergency service, transporter (national grid)
My parents live in Conwy can come and take a look for you, for free of course, can cap that old gas off for you if it's live, takes 30 seconds. And I live not far from Chester, although I know "Cheshire" spans a big area.

Thanks! I used to live in Macclesfield but we moved to Conwy just before Christmas. My wife's parents are visiting this weekend so her dad (a retired builder) is going to have a look at it and see what he thinks. Currently we're thinking it's the water pipes from an old Baxi back boiler and the electrical cable would have been used to control the flue opening. I may well be in touch though! Thanks again!
 
Hey phil my bet wood be oil fired stove with back boiler for hot water/ heating if there’s a thin bore copper pipe that would be the oil feed normally about 10mm. Electric would then be for ignition and fan/injection
 
If you do have an oil feed, consider putting a used oil stove in there.

Noone wants them nowadays. Cast iron models with electric ignition are dirt cheap - £50 to £100.

Virtually zero maintenance. Very clean burning. 80 per cent efficient. I have a log burner in another room, but much prefer an oil stove.

I replaced an open coal fire with a second hand oil stove. Huge improvement.

I then installed aircon, rendering the oil stove redundant. It sits there now, not harming anyone, acts as an air vent and looks perfectly nice.....

Ok, verdict from the father in law is that it's definitely old water pipes from a back boiler. Can't tell if they're still in use or not or where they go to after this fireplace. Bad news is that he thinks that board is asbestos. So I'm not sure what to do about that now. I bought a fireplace this morning which from the dimensions sounds like it will go in without disturbing anything. It's never going to be used as a fire either way. Not quite as grand as the one I'd hoped to put in there but still a massive improvement on what was there.

Get it out, dig a hole in the garden and bury it somewhere it wont be touched. Whatever you do dont disturb the surface, or break it, or drill it. Wear a mask.

Asbestos involves specialist contractors who charge £££. You cant dispose of it anywhere safely or legally.
 
That asbestos isn’t too bad, plenty of asbestos roofed garages still about, using similar stuff. it’s the flakey blue stuff that they put round heating pipes that is nasty (I removed a heating system in my last house that had it round one pipe. I just got suites and masked up, carefully removed it so as not to create much airborne particles, placed into a thick poly bag and sealed. At the time the local council dump happily took it for free, was back in 1993!
 
You can take the asbestos to the recycling center in mocdre, it's the closest one to you, as long as it is double bagged and sealed

They have a "special area" where you put it

Its free to do it too 👍

Alternatively you could just leave the asbestos alone and put your new fire place in? It’s only the partials that are dangerous if breathed in when it’s broke.

That's what I'm thinking of doing. I probably already got a lung full of it when I pulled the plasterboard off. It's cemented onto the bricks above and I can't think of a foolproof way to remove it that doesn't have a degree of risk of damaging the board.
 
The Tape on pipes is to stop the cement mortar corroding the pipes , it's a common practice back in the day .The board from the pic looks like fire Tec boarding what I used when I was working at Royce's .As Allen said at least it's not the blue stuff which looks like someone been using a golf ball on the back of it .Mask on take it out ,bag it ,dig a hole and it's gone ! Just by uncovering the board the wind from the chimney is blowing that board dust in your house right now ,so get it out or cover it up asap !

Aaargh! That is also what I was thinking. The chimney is capped off I think on that one which is why it wasn't vented. But still, yeah.
