New builds zone valves on combi

[Burger]

This is part of why I don’t do house bashing!

Is the other part because they may stipulate plastic piping?

If you’re right Craig, that **** architect cost me lots of money and time in unnecessary work.

But even the BCO said the houses had to be zoned.

I'm no expert on the subject, after all I do only fit bathrooms (whistling emoji) , but that's the way I read the building regs. And as far as I'm aware it is only deemed good practice to zone your heating off in properties below 150m2 floor area.

You’re probably reading it, as it is. We can’t know everything, far to much ever changing bureaucracy. We do have lives outside of our careers.

We're supposed to have lives outside of our careers? Can someone please tell my boss that . You are right though, they do keep changing, they need to make their mind up and just stick to it. Trvs for example, when changing a boiler, used to be recommended, then went to mandatory and now back to strongly reccomended. You can understand when changing a rad that as a drain down isn't required you can't force the customer to have a trv. But why it isn't mandatory for them while the system is drained for a boiler swap is just stupid.

The powers at be, just like making it hard for us

I am sorry Craig but where does it state TRVs are only recommended ?
a. Each space heating circuit should be provided with:

1. independent time control, and either:
2. a room thermostat or programmable room thermostat located in a reference room[6] served by the heating circuit, together with individual radiator controls such as thermostatic radiator valves (TRVs) on all radiators outside the reference rooms, or

individual networked radiator controls in each room on the circuit.

I can't ever remember a time there couldn't be installed if they were not where before.

You are the pro's guys, why is it so difficult to say up to date with what is required ?

The link I posted is the proper current Part L requirements, it just requires a small amount of reading.

I am not being funny bogrodder but why would you be relying on an architect to tell you the requirements for a heating system? I can understand your frustration with BCO you should know but seem to no be interested in any of it.

Page 19 of your document. When replacing a boiler, upgrading to trvs is only deemed good practice and isn't actually a requirement.

As Craig has just said above. For existing central heating systems if the boiler is changed then its only classed as good practise to fit TRV's and. Not a requirement as per table 4.

I have uploaded the snapshot of the document as some may find it useful.

It does however state that if a new heating system is installed (even if existing pipework is retained) then it does require TRV's to be installed on every radiator that isn't a reference room (one with an interlocked thermostat control).

Which I'm assuming would be the scenario where the boiler is being changed and new radiators etc at the same time utilising the existing piping that is already in place.

 

[Mastermixlee]

Then again it does also state in the document that every system should be flushed through thoroughly before a replacement boiler is installed... And that seems to often get avoided by many to offer a cheaper quote and win a job which also voids customers warranty on the boiler.

I think based on all the contradicting and conflicting opinion we can probably agree that until the profession is correctly policed then you are going to get constant discrepancy and differing opinion of what is a nice to have and what is mandatory. I would love to see this job licensed the same with gas. None of this “competent” rubbish if you haven’t got the ticket you can’t do the work. Simple
