combis v gravity ( and engineers )

[bernardgreen]

ianmcd, You are not an engineer, you are an installer or serviceman. Engineers are graduates not guys who have picked it up. It is clear you haven't a clue what an engineer is.

Not all genuine engineers are graduates, some people have in them the ability to learn and develop themselves and thier abilities without attending a university. Often these people are far more valuable to industry as they have the practical experience which graduates straight from university seldom have.

From that locked thread

So a mains fed cylinder offers no more than a mains fed high flow combi

That will depend on whether the high flow combi allows the full flow available to pass unrestricted through it's heat exchanger. It might be "high flow" but not "total flow"

That crap has really p,,sed and fuked me off all my life....Some nobend with a degree in electrical eng who cannot wire a plug calls himself an engr because he is a member of some institute,,,yet a guy with HND. .loads better at the job,,is a technician.. Its a load of fekin nonsensical SH,,,,T

I have a very good idea of what an engr is.He is the one with the bits of paper,no experience,,,who stands and watches the tech guy do the work and say "that looks easy"yet the clever feker can not do it himself.That,is an engineer.

Find out what engineers are and what they do. They do not wire plugs or swing on stilsons, although those activities can be fun.

In the commercial sector, an engineer will design a heating & water system, say in a new or refurbished office block, using some heavy maths along the way. He may design a whole gas system and not be GasSafe registered.

• He designs it to the requirements of the architects at times working with them.
• He will get the assistance of controls engineers, a specialist field, who will draw up control system drawings to the mechanicals that need controlling. The controls engineer may add value in suggesting superior new controls methods, which may reduce the mechanical aspect. The controls engineer may be implementing a Building Automation System to specifications.
• The engineer will have to work with an electrical design engineer to ensure there is electricity to the mechanical equipment.
• From these drawings, pipefitters, electricians, ducting men, etc will install the equipment.
• The hands on men have no say in the design, sizing, etc, etc - most of it is beyond them. They follow the drawings.
• Any deviation has to be approved by the designing engineers.
• When complete, or a phase is complete, the commissioning men will move in, like controls men, air system balancing men, etc.
• Then when conforming to spec, it is signed off.

In the domestic field the design is largely rule of thumb, with the hands on men having a go at the design and doing the fitting. Hence why many domestic systems are a mess, not being fit for purpose.

And not forgetting that most customers won't pay for proper design....they won't even pay to have a radiator correctly sized with calcs.

So they get incompetent cowboys a lot of the time.

The same applies to an unvented cylinder as they have pressure/flow restrictions through the valvegear.

Im 55 and do not need lectures from you,having worked with "engineers" all my working life

You patronising nob

You sound fresh out ofcollege or fresh out of cloud cuckoo land

durhamplumber,

I am telling you how it is with the procedure. I do not look down on hands-on people who know what they are doing.

And I am telling you what reality is like

Lol...me too..in 1984!

If you have ever worked on any big commercial job, which I doubt from your response, you will find that the procedure is as I laid out.
