    Choosing the right pump

    I have finally decided upon my hot water system. Having discussed it with Building Control I now know that I can't have an unvented system without too much upheaval, so I've decided to go for a vented set up. To save space I'm having a mains-fed Triton remote Aspirante shower (fitted with my own...

    What size of unvented water heater....

    would be required in order to supply a kitchen sink and bathroom basin (no bath, shower is electric) in a one bed flat? I've been looking at the LWC 50 litre cylinder but wondered if I might get away with a 15L Heatrae Hotflo. Cheers.

    Help me choose a hot water system!

    First of all, there is no gas and whatever system I go for it needs to be less than 500mm in depth because that's how big the cupboard is and for various reasons it cannot be made any bigger. I also don't have a loft space. The central heating will be electric and there is no bath so it will...

    Unvented System Discharge Pipe

    Hi all. Is it OK to feed the discharge pipe from an unvented system such as a Megaflo into a 40mm plastic shower waste pipe (or linear shower drain) which in turn feeds into the soil stack? I was thinking of a run along these lines: Unit - metal pipe - tundish - metal pipe - shower...

    How many downlights to use?

    How many dimmable 50w downlights would you all recommend for a room of 17ft by 11ft? The ceilings are 8ft high. I think 9 (3 x 3) but have been advised that 6 ( 3 x 2) would be more than sufficient. Also, the ceiling is 12.5mm plasterboard with a skimmed finished so would 60 minute...

    Creating a fall in wet room

    I am making a wet room using 12.5mm Wedi backer over chipboard. I can't access the joists below the chipboard so can I just create a fall by feathering the tile adhesive or would I need to use another method? I don't really want to raise the floor in the shower area because there would then...

    Extending the cable that goes into the consumer unit

    I need to extend the big black cable that goes into the consumer unit so I can move it higher up the wall. I need to extend it by about 1 metre. The cable is rubber coated and contains 4 big wires, yellow, red, black and blue I think. Is this quite a simple job for a professional electrician or...

    If a stud wall runs parallel to an RSJ what is the usual method of fixing the head plate? Is there some sort of tie or other fixing available or do you screw into the RSJ?

    How many screws per timber-to-timber joist hanger?

    The timber is 7x2, the span of each joist is approx 30cm (they're trimmers you see). I called expamet who make the hangers and they said use every hole! I was hoping to save a bit of time by using about 4 screws per hanger but I don't want the floor to collapse. The screws I was planning...

    Would 3x2 timber be ok for a stud wall if...

    on one side of the partition was a wetroom (18mm ply + limestone tiles) and on the other side 12.5mm plasterboard? Or should I go for 4x2 for extra strength?

    Electric Hot Water System

    Hello all :D. I'm in the process of modernising a 'compact' one bed flat (350sqft) and have removed the old water tank & cylinder because it was in the middle of the flat and I needed the space. Now I'm deciding on what sort of system to replace it with. I do not have a gas supply so it's...
