I always thought pipe sizing and rad sizing was pretty basic stuff at college? They stopped doing it?

 

[Pawel Halarczyk]

Unfortunately I didn't do any of it, Ive learned which metal corrode which, but it never came handy yet lol

I'd stay on the books then and give the self employed a skip.

Bloody hell pal, with the greatest respect that is a huge job , be very careful.

I'm with Simon on this one. If you don't understand pipe sizing or which system to fit in different properties then I would reconsider going self employed. Are you gas safe registered?

Hello everyone thanks for taking your time reading my post I am new to this forum.

I am level 2 plumber with 5 years experienced in kind of aspects of plumbing and pipe fitting.

I am considering going self employed , I've been asked to price up my first job, barn which is spilt in to 4 diffeent houses.

and I am struggling with couple of thing's like sizing pipes feeding cold/hot/CH and sizing pumps.

I should price up for ( unvented cylinders and heat only boiler)or combi boilers will be enought to power hot water and central heating for each one of the properties?

How is everyone sizing radiators? Is there formulas or most of times you just go by the eye?

Any help would be appreciated.

Where in the world are you based Pawulony? As described above you should be very careful as it seems to be a relatively big job though. Have you ever installed a system from scratch?

 

[Pawel Halarczyk]

No I would get someone in commission the boilers off. I would do all the first and second fixing.

You aren’t allowed to install them.

Ive installed full central systems with 3 diffeent heating zones, also I use to marry cylinders together the problem is that I havent got a knoledge in sizing stuff as I've never been introduced to it.

Especially when combining systems it is very important to know what your doing

If you feel like doing it, that’s your choice. Also to sign off is so wrong.

Just because lots of people do it, doesn't mean it's right. To work on gas you should be supervised at all times by a registered installer. Not just getting someone in at the end to check it.

Almost everyone on here would have been paid duck all for donkey work in order to get their qualifications, it's called an apprenticeship. It's no excuse to break the law.

 

[SimonG]

Still struggling with level 2 and no pipe or rad sizing!

Most of it was straight swaps but I did small central heating couple of weeks ago
