Boiler Re-pipeing

[stevetheplumber]

sorry failed mis read the typo if and of

 

[Whyme]

Any who i reckon 22mm is future proof.

Hell this is getting highly technical, you lads have lost me and I never thought that would happen, time a get out the bomb calorimeter again, mass gas chromatograph analyser and a pair of 36" stillsons, oh a stop watch and a 12" manometer the later can only be connected to the gas by a GSR so that me out.

sorry ermi your wrong there is no suction on the gas pipe work before the valve
if you have a 30kw conventional boiler with20mb inlet and 1 mb of drop on the pipework and you fit another 30k zero govenor boiler you will still have 20mb and 1 mb drop so wheres this suction?if there was a suction effect on the pipework we would need a different set of pipe sizing tables

Try it.

 

[Ermintrude]

I shall record on next undersized . There are a few logics on a 22 mm supply will try and gas rate them . 30kw system boilers 15m ish of tube few bends

thats incorrect zero govenor boilers do not pull on the supply if the did we would have had to change our pipe sizing to still have a 1 mb drop personally ive had no updates requiring me to change pipe sizing methods

you have never seen a boiler "pull" the gas from a cooker? term it how you want there stealing gits on poor supplys.

 

[Ermintrude]

Seen plenty of fires sucked out

in a mates brand new house his hob goes out when the boiler fires on hot wata. So anybody who thinks a "national house builder" does not employee the same cowboys as small frys think again.

infact the bigger the builder the worse the work seems to be from my experience. Ive been on a site this week belonging to the biggest building company i know. The standard of the plumbing is shocking.
