The smaller tank will be the header/expansion tank, it only looks about bucket sized although rectangular.
Yup thats the one. I should have taken some pics but I just wanted out of there its orrible in the loft space. I had
a mask & woolly hat on so was very warm.
Put a wee tree that lights up ootside & stuck some tinsel n stuff to get into the Chimbo spirit.
Not done the hoose lights though its hammering it doon.
Fire turned up & having some cheezy crackers before dinner. Dogs r sleeping as I tired them oot with there tennis balls.

Funnily I have boarded at least half of ours, put lights up all over and we use it all the time for storage. But if you cannot stand up in it, at least in the centre, it's a right pain in the rear!
No you can not stand up, we were having a chat earlier about lowering the ceiling & putting a dorma round the back of the roof.
She's told me that one of our neebs houses might be coming up for sale in the new year & I said if it ever came up for sale id like
to buy it. Its been in the same family as far back as I can find, needs ripped apart....only got a coal fire which is open. single glazed
sash n case windows & the interior would do well on antiques road show
Its been empty for over a year cause the old ladyis now in a home. She would have got back home but didnt want carers in the house so shes been papped into a nursing home.
Feeling I have been dumb. Just noticed you said "header tank" as in the tank that keeps the central heating system topped up.
I think it might even be called the "expansion tank." That makes more sense as indeed they do have a ball valve and an outlet that pours into the tank, which (sticking my neck out here) comes from the system when the water expands on being heated by the boiler and has to go somewhere rather than blowing up! Ours is a big pipe that goes up the outside of the tank then curves over to let the water fall into the tank.
But again I may be wrong and your ordinary cold water feed tank that is huge and sits in the roof as originally organised Lord Congreve! Is the one you are talking about.
"In 1809, Congreve rockets were used by the Royal Navy to set fire to Amsterdam. They did a very effective job as there were no water sources available to put out roof fires. The UK government realised the vulnerability of London, and decreed that all buildings should have a large water tank in the roof."
@brianp38dse or @gstuart may be able to help.
Glad you are, at least at the moment, sorted.
(Don't forget to NOT insulate under the tanks!!!!)
Don't insulate under the tanks, let the rising warmth do it's job, only insulate top and sides ...
Was putting new ceilings up in the dottir's house earlier this year, found exactly the same thing. British Gas certificate for the loft insulation pinned to a roof joist, plenty of insulation over the general area but none in the eaves. Radiator heat would have been going straight out through the ceiling at the eaves. Had to put a load more insulation in.Its a modern plastic thing looks cheap compared to ones for sale now. Its working fine atm but I will need to replace it
& probably do the insulation properly as its not done the way I thought it was. If you poke your head up it looks all good
until you climb half way along then its only done on the flat ceiling part not going down into the eves.
The certificate is nailed inside the roof. Not worth the paper its written on.
Really why not just do them properly
I did wonder why top off the roof was frosty & the lower wasnt, I knew I was loosing some heat no wonder.
There must be thousands of homes done the same way. Boils my blood that does.

Eye fort the last bit near the guttering weren't filled wiv insulation to allow the roof to breath.
There was a time when the official advice was not to put insulation right to the edges so as to help prevent condensation. This included not stuffing it down the gap between the roof and the ceiling in houses where the outer edges of the ceiling sloped down with the rafters. You'd got to leave air gaps, apparently. Personally, I'd rather have insulation all over my ceiling, including right to the edges, but then I'm not the person who makes the rules. So it may be that these installations went in when that was what the prevailing guidance was.
That makes sense. But the loft insulation should reach the perimeter walls, dottir's insulation stops short by about 18 inches.
On a similar theme, I won't have cavity wall insulation as it stops the "breathing" that a cavity was originally designed to do. Modern cavities are wider, with board type insulation held in place to the inner brick skin with clips, still maintaining an air gap at the outer skin. (If they are built properly that is). That cannot be achieved with blown-in foam or wool, as has to be done for uninsulated cavities and cannot be inspected for quality after it has been done. Dottirs house has been done with blown-in insulation, and at one place where I cut a hole for a new drain pipe, I could see the insulation was very deficient. Think the previous owner got ripped off.

There be two problems wiv blowing little balls inside a cavity from what eye have seen online. Yer dun't know if they fillit propper. And they stop air flow which stops moisture drying oot. Eye fink later foam type insulation is attached to the inner wall so water can run down the inside of the ooter wall. Gap at the bottom to stop it soaking up. Peeps who blow the balls in now offer to suck em oot. Eye watches collison bricklaying on youtube. He mentionned it.

Exactly right. Dottir's cavity insulation is I believe, blown-in wool type which was popular a few years ago. And can end up as a wet sludge at the bottom of the cavity because it can't breathe.
