    worcester bosch W11 water heater

    Hi am looking for some help with a water heater that has been driving me crazy. I fitted the Worcester Bosch W11 in a caravan around about a year ago, after fitting this boiler I was having problems with the boiler shutting down occasionally when hot water was flowing so i changed the flow...

    nobody asked for homework to be done chuck, the forum is about asking questions that we are unsure of, if you have nothing good to say then best say nothing

    bs en 806-3 pipesize

    so I am also assuming that because the simplified method (806) does not account for fittings or for losses through valves then the designer would have to take fittings as a percentage loss and valves as metres head lost when working out pressure loss within the pipework to make sure that the 1...

    Yeah that explains a bit, the pressure loss/gain when elevated would be the same regardless of pipe size. the only difference is the fact that 6700 or 8338 gives the opportunity to work out the total head loss and 806 doesn't. I'm assuming that the pressure loss would then need to be worked out...

    I am going to have another look and think about the standards now and see what I think

    bs en 806-3 pipesize

    Don't worry I wasn't offended, I am doing a building services course, not an English course so they are prob not as strict. In class my punctuation prob a little better anyway. you were right anyway, I wasn't getting my point accross at that time but hopefully you know what I'm talking about now

    thanks Rik, let me know what you think.

    The only other way I can put it would be, if I was planning for a building with 6 loading units and 25 metres height, with an initial pressure of 3 bar, then surely the 15mm pipe recommended in 806 would be no good due to the initial loss of head on vertical riser

    Just read this back, it's not the best grammer in this either ha ha......... I should start reading these before posting.

    bs en 806-3 pipesize

    ha ha I didn't think I would be tested for grammer on here, anyway what I am trying to say is that on 806 a pipe can be selected using only flow rates as probable demand and has been accounted for within the flow rate. My question Is why is there nothing mentioned about the pressure that is...

    I have also been asked to do 3 othter types of design and compare, of which I am using thomas box, bs 8338 and I can't think of another way to do it, if anybody can give me one more suggestion

    bs en 806-3 pipesize

    I am currently doing a project at uni, on pipe sizing and can't understand why bs en 806-3 does not take account for elevation into pipe sizing. I understand that the loading units have been accounted for so probabe demand is not necessary and that head loss through pipework is taken care of but...

    flue terminal too close to cooker vent

    some advice needed, I could do with some input on a fanned flue outlet being 200 mm away from a cooker hood vent, the vent has flaps which close when not under positive pressure from hood. would this be classed as safe due to the flaps closing when cooker hood not in operation. I respect the...

    fanned flue terminal

    bit of guidance needed. I have a flue which is round about 200 mm away from a cooker hood vent, the vent terminal from the cooker hood has got flaps which are closed when the cooker hood is not in use, so effectively only open when under positive pressure from hood, just a bit unsure as to what...
