    Adding smart hot water controller to boiler with multi-zone central heating

    Hi, I have a Vaillant Ecotec Plus 618 in a 3-floor 7 bedroom house with 2x 200L unvented cylinders and 3 central heating zones. The central heating has 3 wireless roomstats which I'm upgrading now to ones with wifi, but the hot water has no timer/controller at all and both cylinders operate...

    Overboarding 11mm ply and ditra matting (thick floorboards)

    We're converting the corner of a bedroom to a 1.2 x 3m en-suite bathroom (shower, actually). When we removed the carpet we found there's existing 11m ply lying on top of 28mm floorboards (original old timber ones, not T&G) which sit on 8" joists. The span of the joists is 5.5m. My...

    Condensation or damp

    We've got a first floor flat with some mould appearing just above the skirting. The tenant claims that it must be penetrating damp coming through the brickwork somehow - perhaps poor pointing. I can't see anything wrong with the brickwork except for a few pockmarks but I'm not certain it's...

    Dimmable LED lights: GU10s or shallow panel?

    We've completely refurbished and rewired our house, and allowed for 8-9 spots/downlighters in a six 4.7m x 3.2m bedrooms (2.45m high) and in hallways and bathrooms. The ceilings have about 25cm between plaster and floorboard including fairly high grade rockwool. The wiring is already done (9...

    Waterlogged floorboards during building

    In the middle of a home extension which includes entirely new roof, and new joists and floorboards. Before the xmas break they left the ridge tiles and other gaps in the roof, and no scafolding with cover, so it wasn't weatherproof. With the recent heavy rain we've quite a few days of rains...

    Fibreglass resin to repair an old felt roof

    I manage a freehold property and a 99-year leasehold tenant on an upstairs flat has a leak in the corner of her bedroom. I went up on the roof and it definitely needs urgent attention. The felt has bubbled up in a few places and lead flashing loose at several of the edges. In particular it...

    stud partitions on top of damp floor with membrane

    I've got some builders refurbishing a flat that has rising damp - the concrete floor was measured as very damp all over and apparently was laid almost without any damp proofing. We got a damp guy who injected a new DPC and rendered the walls about 50 cm high (till 20cm above the DPC) with a...

    extension sockets instead of proper sockets on a ring main

    We want to provide mains power to some desks in the middle of a open plan area, which has a concrete floor with laminate flooring - so no where to run cabling under the floor. The desks will have between 2 to 8 computers (and their screens). The problem is how to get the ring mains to this...

    Many computers in office. How many circuit breakers?

    We're wiring up a new large office but I don't trust the electricians calculations. We allowing for about 21 computers (mixture of laptop and desktops) and at least 30 double sockets (for phone chargers and assorted electrical equipment like routers and printers). There is a standard...

    Suitable trim for inbetween partitions

    We've installed some second-hand office partitions that are metal rimmed and set into a timber (3x2") frame. We're looking for an appropiate trim to cover the exposed timber and the metal frame which is a bit worse for wear. See pic at end of post. We could use wooden beading or architrave...

    breaking suspended ceiling to get height (edit)

    We've got double glazed glass partition units on the cheap to act as our new office partitioning. Problem is these units are 257cm when the floor to suspended ceiling height is 254cm! Since these glass partitions have to sit in a timber frame that adds another 4 inches. There is about...

    glass office partitioning - laminated double glazed and cost

    Hi, we're partitioning our offices internally. We want the 5 offices to have glass fronts for light and feeling of openness but we want it to provide some measure of sound proofing. The main issue is cost. Which would be cheaper, but taking into account sound proofing, laminate or double...

    office partitions need to conform to building regs?

    We're dividing a large office space to sublet part of it. So we're building new internal partitions (studwork with glass panels inset for lots of light). Do we need to worry about building regs on this, e.g. checking the glass is the correct BSxxx standard or whatever? Obviously we'll do...

    Glass office partitions out of shower panels?

    Further to my other question about building cheap glass partition - someone mentioned building regulations. If I can pick up shower panels (i.e. full height side panels for a stand-up corner shower without the door part) cheaply (say £80/panel) can I use these as office partitions? I'm...

    Cheap glass office partitioning

    We want to create 4 offices out of a large open space, each about 3x3.5m, in a line (with shared walls) - 18m of glass partitioning. Natural light comes from the two sides so we want lots of glass to let the light in the the middle offices. Real glass partitioning seems to cost quite a bit...

    Shower on megaflow (unvented) system fluctuating temperature

    I'm in a flat where the hot water (& cold) is centrally supplied to all flats on a mains pressure (megaflow/unvented) system. The shower in my flat has a manual mixer (not thermostatic) which doesn't seem to keep a constant temperature it fluctuates making for an uncomfortable shower - one...
