8m of 35mm @ 0.00084 pm
7m of 22mm @ 0.00032 pm
12m of 15mm @ 0.00014 pm

8 x 0.00084 = 0.00672
7 x 0.00032 = 0.00224
12 x 0.00014 = 0.00168

total pipe work volume = 0.01064 m3

+ 10% = 0.001064 m3

Pipework volume + 10% = 0.011704

meter (U6) 0.008 m3

total of meter and pipework volume = 0.019704 m3

total installation volume = 0.019704m3

nice one that looks like what I got now....sorry to be a pain but do you have any advice on unsafe situations? I find it a nightmare distinguishing between AR ID and NCS? is there like a rule of thumb? as an example one mock question was ...You see a scorch mark on a carpet below a radiant gas fire how would you classify the situation? I put ID as at any time it could set the carpet alight but the tutor said its AR which surprised me.

the carpet is only at risk of going on fire,
