You can if you understand the input/function/output. That's why I post here for an advise. For someone who knows the subject it's probably 5 min job to look at the calcs, changed input and judge the output. Furthermore, there will be many people who installed tens of beams in exactly same...

Thanks Tony and Woody. Any technical input is appreciated.

I haven't originally, but now updated the original post.

Tony, not sure what was in mind of the architect/structural engineer, but I can't see correct floor load in the original calcs. For my assumptions I took 1.4kN (dead) +1.6kN (live) = 3kN/m2 for the floor load. It looks to me as overkill, but that's what I came across in a couple of docs I found.

Woody, I have not changed the calculations. What you see attached are the original calcs I have, however I listed the load I believe is correct which is higher than originally calculation, but still several times less they are compared within the calcs. I agree, load from the 8x3 is higher than...

Hi All, I am after some advice on the structural calculation I have for first floor beam support which replaces internal brick wall. The calculations have been done a while ago and I can’t get in touch with the architect and the structural engineer who did it. At the time it was done I...

Hi. First of all I would try to find what is the pipe size. If its 15mm get a push fit stop end (screwfix/toolstation). The pipe would probably come from your house pipework, so switch off the water supply at your stopcock where water supply enters your house. If it is not working, you can shut...

Hello All, Currently I have a clay drain pipe connection from my stack (outside back wall) to the manhole which is on the neighbor land, so I have no manholes on my land. (see diagram below). As per the diagram I am planning to build an extension over the pipe. I am planning to replace part of...

I have added wiring diagram which I created based on the diagrams available on the Internet, manufacture installation guides and comments from this forum. My main question is the boiler control (demand) done correctly? Please comment.

Hi All! Design diagram has been updated. -) Expansion vessel is added -) Condensate drain changed to an optimal route Pipework diagram has been added. Further comments are appreciated. Q1.Is it correct approach to use 22mm when it goes to more than one radiator and then split it to...

In WB 30CDi installation guide I have noticed: I wonder how would you practically measure that. By pure estimate calculation or filling in the system and draining and measuring? How much water 7-8 radiators CH system in 3-bed semi would normally use? Anywere close to 100 liters or it's...

Updated the diagram accordently.

I have updated the diagram with the most changes proposed here: -) TRVs removed in the room with the thermostats -) Valve removed from hot water outlet -) Drain valve added to the CH flow at the lowest point Question: As the boiler is at the highest point of the system can it be drained...

Will do indeed, however always good to have several professional opinions.

Any specific reason for avoiding wireless? The idea is to use Honeywell CM927 which can be moved between bedrooms if required. When it's taken into to the room the thermostatic valve would be fully open. On ground floor mainly to avoid wiring. Unfortunately, the kitchen is not big enough...

I tried to draw water and CH supply inluding all elements. There are pleanty diagrams in the network, however most of the don't show valves and cocks. Please advise if anything missing or placed wrongly. I was trying to use correct symbols, but could not find all. Any advice appreciated.

Please advice on below. My apologies if it's been already discussed on the forum, but I spent 1 hour and have seen a number of topics on the requirements for moving boiler into the loft and a number of topics around issues with heating in the converted loft, but nothing on the requirements...
