    Wiring question

    Sounds a right mess. Sounds like the transformer isn't connected to anything which is why it doesn't work. but you say it used to, which is odd. If you know what you are aiming for ie three terminals in your main junction box or ceiling rose, which are permanent live, switched live and...

    maximum size consumer unit

    If what you mean is the largest MCB he can fit on the circuit (not the largest consumer unit, which makes no sense) is 32A, then this is true. He can't uprate the MCB without rewiring the circuit. What is this heating system you've had fitted? Is it all electric heaters and all on the same ring...

    Old (old) house mortar is shot in many places, replace with?

    Mine is 400 years old and not listed. Being old doesn't necessarily qualify them for listing. Yes, speak to lime.org, they are very good. Definately don't use cement on old bricks, not just because of moisture and breathability as mentioned above, but because as the house shifts about as they...

    What type of hot water system to have?

    "Small system boiler and unvented cylinder if you have the room and water pressure/flow, you will also have an electric back up for the hot water ." No, definately no room for a cylinder. "You may even meet someone who expects you to wash more often." :lol: "The heat load for this...

    What type of hot water system to have?

    Yes a combi is the obvious solution. It's just that 7 years of reliability doesn't seem very long. I also hear in the news that gas prices will be inevitably rising, whereas we may perhaps be able to find new ways of generating electricity in the long term. I plan to grow old here, and don't...

    What type of hot water system to have?

    Well, the house is old, and although small, it is largly solid wall with a lot of external wall for the space, which means that the BTU calculations actually come out quite big. Using the online calculators: Living room/ kitchen: 11100 BTU Bathroom: 2397 BTU Study: 2218 BTU. Total 15715 BTU...

    How to wire now, for future solar PV

    Ok great. That's the answers I was looking for! The panel end of the cable could presumably just be left coiled up on the flat roof for now, and if the inverter can go in the cupboard under the stairs with the CU, then I don't need to do any of that wiring now. The inverters look quite big...

    What type of hot water system to have?

    A temporary bathroom with a temporary power shower. All very primitive I'm afraid, and doesn't get used as often as it ought to! OK, I'll look into that - plume management kit; system boiler; Intergas - googling all that now. Thanks!

    How to wire now, for future solar PV

    I am renovating a cottage which has a large flat roofed extension on the south side. I don't have the funds right now to install solar PV, but while I am rewiring the house and have the floorboards up, would it be a good idea to run any cabling which would allow me to install solar PV in the...

    What type of hot water system to have?

    I am wondering which type of boiler to have. There is currently no central heating or water heating system in an old cottage which I am renovating. It's a tiny place and my hot water requirements are minimal. I am intending to install radiators, but am wondering about how to create hot water...

    How To Fix PIR Below The Rafters

    I believe that drywall screws are the norm, but I know what you mean, they tend to disappear into the insulation. What I did, was to use small squares of cardboard, just to stop the screws from disappearing into the insulation. Then when it's all up and you are ready to fix the plasterboard...

    New central heating system- type/size of pipes under floor

    Hmmm. OK. Compression fittings under screed doesn't sound like a good idea. But a drain off at under-floor level is perhaps a good idea. Thanks for the confirmation that any unregistered person can do the pipework. I won't try to do the gas work in any case. I don't think rodents will be a...

    New central heating system- type/size of pipes under floor

    I am having an inch thick solid oak tongue and groove flooring laid onto joists, over insulated concrete on the whole of the ground floor. First I must lay central heating pipes. It's an entirely new system. Is it best to use plastic or copper for central heating? What size? Should they be...

    Squeaky flat roof

    I have just had a new flat roof, with new joists, and firrings which significantly are positioned perpendicular to the joists, over which is 18mm OSB and a fibreglass roof. When temperature changes occur, in the morning and evening, the roof goes "doink!" over and over, until the temperature...

    Mesh wing or perforated wing on drip beads

    I'm buying a considerable quantity of stainless stop beads, drip beads and movement joints for external lime render on a very old house which has some modern extensions, therefore different substrates. I see that there are stop beads and drip beads available with either a mesh wing or a...

    Lead "stitching"?

    My new roof finishes inside a gable wall with an upstand. The roofer will be doing the lead work to bring the rainwater round inside that upstand, and the builder tells me that the lead will have to be "stitched" to make it one piece, rather than simply overlapping several pieces of lead. Can...

    Fitting new timber windows

    I'v'e fitted U-PVC windows before but am having new timber windows made for my house and would like to fit them myself. Is there anything I should know which makes fitting timber windows more complicated than fitting UPVC ones? Is there any more to it than marking where the fixings will be...

    window sill extensions external insulation

    My understanding is that if you were either building from scratch or having new windows made, you build a ply box which extends out into the insulation, so that the window sits out in the insulation, but its weight is held by the ply, which is fixed into the wall. I understand this may not...

    Underpinning garden wall

    Hi. I have had to lower external ground levels on my 18th century house, so that they are lower than internal ground levels. There is a narrow sideway where I have removed the concrete slab, but this leaves an adjacent garden wall with no foundations. It was sitting on top of the slab. The wall...
