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

 

[SimonG]

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

 

[townfanjon]

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

 

[Aire]

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.

Ive install around 30 oil bpi

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!

 

[Pawel Halarczyk]

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

Pawel, just trust the engineers on here mate. Follow the rules and get more knowledge and you will see things becoming much easier. The majority of people on here are highly trained and have huge background of plumbing. The engineers did not just spent their hard earned money for endless trainings but also for the knowledge to become a great engineer. A lot of people on here have over 20-40 years experience. I would say stick around here and try to pick other brains knowledge. If you feel ready then please be my guest and go ahead but you may end up having an installation issue and that could cost you money to fix that and not only that but perhaps a customer or more.

People on here will be more concerned than upset. We've seen bad gas work and we know the consequences of it. I'm not saying your gas work is bad or dangerous but you don't hold the qualification so it's irrelevant. If you really want to go self employed then speak to your local assessment centre about what you require to get your acs. Building a portfolio of gas work shouldn't be too difficult. There's always someone who will be willing to help and if it mean getting paid peanuts, if it gets you qualified then it's worth it.

Thank you for your kind words mate. Ill have to really think through it now i feel confident installing systems but not designing them unfortunately.

But how do you want to install a system but not being able to design it? That’s the most important when going self employed. You will need to know what to suggest your customers the right system and make that work otherwise you won’t be long in the game. It is a really hard to be self employed it is not everyone’s thing to be fair.

Second that. Plus you need to be level 3 for gas unless things have changed.

You don't need level 3, it helps but it's not needed, I haven't got level 3😳

 

[BYP]

I was under the impression that you did, have things suddenly changed or does it vary from course to course? We didn’t really cover anything gas related until level 3
