    15mm hot water supply to existing 22mm piping - problems ?

    Why would there be a loss of pressure ? As I see it, the current piping is 22mm down to 15mm. The proposed will be 22mm to 15mm to 22mm (short run) to 15mm. The minimum size remains the same in both cases. Why would you use an immersion and tank ? You limit the amount of hot water you have...

    15mm hot water supply to existing 22mm piping - problems ?

    Wouldn't change what ? Current system is defunct or thereabouts, putting in a new immersion heater is just old technology (and always limited quantity) and I've used instantaneous heaters for years with great success. I would obviously prefer 15mm pipes all around but that would vastly...

    15mm hot water supply to existing 22mm piping - problems ?

    I take your point on the lead in cold water but we'd have that to get through in any case, though pushed through at 22mm and not 15mm I agree, thus delaying somewhat the hot water at the faucet / shower head. New system is electric (as is old, no gas on site). Stiebel Eltron DHF 12C1...

    15mm hot water supply to existing 22mm piping - problems ?

    The piping from my old immersion heater tank is 22mm (or imperial equivalent) for some length before reducing as it feeds different places and the outlet from my proposed instantaneous water heater replacement is only 12/15mm. I do not want to rip out pipework unnecessarily but canI live with...

    Best saw for a decking job ?

    What would you put one on whilst using it and do they all have the same fittings ?

    How do I remove a stone staircase leading to the cellar?

    I've the same sort of staircase in a similar house and before I looked I was just going to rip it out, thinking it was a normal staircase but now it is going to stay and we'll work around it.

    Best saw for a decking job ?

    I guess I could see me using it going forward on occasion so something which would last rather than just do this job and then pack in. Maybe up to £200 or so for the saw, perhaps more but a more expensive one has to be better value (not just price) than a cheap one which will do the job now...

    Fixing 4" x 2" to bricks and to aerated concrete b

    A quick google for these does not bring up the million or so places you'd think would be selling them. Where has an online shop ?

    I see now, though I have nothing to cut such bolts.

    How to turn a cellar into a useful room ?

    I live in an old house with a cellar leading down from the kitchen which I'd like to make more use of than just storage. The problem is that I lease the property and whilst I am happy to invest a certain amount, I won't be doing a conversion to the standard I would were I the owner. At...

    These seem great but what size and what to screw into them ?

    Fixing 4" x 2" to bricks and to aerated concrete b

    Sorry, it appears that was lost in edit. The void to be covered is 3m long by 1m wide by 1m deep.

    Fixing 4" x 2" to bricks and to aerated concrete b

    The blocks have been there years, well before me. I didn't build any of the structures but to support the decking, one side will be against the brickwork and the other against this concrete block wall. I will add that there will be posts supporting the cross member which also benefit from...

    Fixing 4" x 2" to bricks and to aerated concrete b

    [/url] I appreciate the suggestion but this is 4" x 2" which is essentially around 50mm thick. Forgive me if I have missed something but just what would I do with something 260mm to 300mm long ?

    Fixing 4" x 2" to bricks and to aerated concrete b

    It has to be very secure as it is supporting decking. What would you use ?

    Best saw for a decking job ?

    I'm building a framework for decking to span a 3m x 1m void using 4" x 2" for joists and pillars and circa 30mm decking. I've obviously got to cut the wood to size and bar a hand saw I don't have any cutting tools. I was thinking of future usefulness as well and thought about a sliding...

    12kw water heater - cost for electric installation ?

    I'm being convinced that some time for obtaining materials is in order but I don't understand why we can't get an itemised quote just to make sure that the guy isn't trying to charge £50 for a £5 item or £20 a metre for £3 a metre cable. Getting paid to go get materials is one thing. Marking...

    12kw water heater - cost for electric installation ?

    I admit I don't know what figures it should be. Perhaps stupidly I expected someone to give me a quote with a breakdown for materials and then a labour charge and a total at the bottom. I will also admit I don't know why doing that is so difficult and in failing to do so, I am sceptical as to...
