Catch up time (Part 2)

Right, so this is after I came back from Holiday.

Nice new floors laid!
 Very nice...
 Looking good!

 Only 2 real dissapointments here, one, they made very little attempt to protect the shower drain, and actually knocked it off center before pouring screed all around it anchoring it in place.

It simply had a rag shoved inside the joint and a plastic (ribbed!) bottle ontop of it, and a piece of polystyrene in the gap where the floor drain is supposed to go.

As a result, the bottle was impossible to remove, the rag was trapped inside the screed, the joint had been knocked so it was no longer where it was supposed to be, tried freeing it off but the screed goes very hard, I'd even say it goes harder than concrete..

 Second niggle, they burried the drain for the kitchen! Then had the cheek to say it was my fault for not leaving a long enough piece sticking up. (there were lots of offcuts kicking around, they could easily have done it themselves, or at least try to put something there to stop it getting buried with screed!

 Anyhow, cracked on with bedroom ceiling

 Metal profiles added.

 Moved onto the roof finally! This is the first sheet removed and already almost fell through the roof.

 peeling up metal roofing sheets.
 Little bit of rot..
 Bitumen paper was used but had frayed through in some places over time.

 Rot? Where?

 And the old roof removed.

 Apologies for lack of pictures, I was too busy! Here it shows the finished underneath.

New roof beams, bolted either side to wooden beams on the top of the walls, used the left over polystyrene sheets to insulate, the beams were 150mm, sheets 100 so it leaves a 50mm gap for air circulation above it.

Top of the beams is covered in 25mm OSB board, Bitumen paper and then the new metal roofing sheets.

Also added the wooden support beams fo rthe ceiling which will now be level opposed to what it was before, at a weird angle.

 Showing one side bolted to top of main bearing wall.

Hopefully, when they come to replace the old roof this new section can stay in place.
 A view from outside, it needs some work done as I didn't leave enough overhang whilst using the 25mm OSB and the brackets for the gutter.

Simply need to take down the OSB facia, and shorten the wooden beams so there's a bit more overhang.
 Added 1x 32A (6mm) cable for electric induction hob, 1x 16A for electric oven and a normal socket for kitchen.
 Plumber also added a Gas pipe so we can choose between electricity or gas Hob or oven.
 The space for the fuseboxes and bottom space for dishwasher socket + countertop socket.
 Bedroom radiator pipes all put in place inside the wall.
 The UFH pipes leading up to the boiler room, along with the gas pipe in gray.

 And all the cables labelled for fuseboxes.
 The Hot water cylinder arrived, and as you can see it couldn't have been much larger!

It's one of these:,3590.html

Basically, its a 400L tank, which we have used in a slightly different way than normal.

Rather than heating 400L of hot water to use for showers/baths/doing the dishes, for it then to cool down overnight again losing energy, its been "inverted" in that its being used as a thermal store.

The main volume of the tank is used as part of the HEATING circuit that does the UFH and Radiators, the return from these goes back into the tank, then out to the boiler, gets heated up, goes to the UFH/Radiators and returns to the tank again.

The side coil is used for the fireplace. This will eventually help warm up the water in the tank, so the gas boiler doesn't have to do so much work.

The top coil is used as a "Pre heat" coil for the hot water. Cold water from the well enters the coil at the bottom, and leaves slightly warmer at the top before getting sent through to the boiler to be heated to the desired temperature.

The bottom coil eventually will be for a solar pannel, which will have the same function as the fireplace, to simply reduce the load on the gas boiler.

The red thing on top is a Feed & Expansion tank for the fireplace backboiler loop.

I chose this model because of its price and ratings, its illegal in some countries to have a sealed (Unvented) system on a Uncontrolled Heat Source (Such as a fireplace which you can't just turn off by turning a tap or hitting a switch)

This means that if the water gets too hot in the system, it will simply evaporate and push it back into the tank, take in a gulp of colder water and cool the system down again.  No risk of explosions or boiling water being spat out into someone's face.  Not to mention, it has completed the 500 hour boiling test where they cycle boiling water throughout it non stop without failing.

 Nice tight fit!

The "temporary" flue for the boiler. It needs to be done again at some point once the roof is replaced.

And then it was Christmas, and I moved away from Slovakia after 3 and a bit years to live in Germany.
