Recent changes to unvented / G3 regs

[Masood]

I'm almost 100% certain there was a thread a little while ago that mentioned the 15lt limit for non-G3 qualified had been done away with, and that ALL pressurised hot water installations had to be done by a G3 qualified person.

I'm also almost sure that the same thread mentioned that the demarcation between unvented and vented had been done away with, and anybody working on stored hot water systems had to be G3 qualified.

Did I dream this? Am I going gaga? If not, please can someone point me towards any documentation outlining these changes?

Ta very much!

You dreampt it

dont believe he did dream that one, vented systems now included under g3 to cover prevention of scalding etc

logic posted this blurb at the time:

Prompted by an increase in reported hot water scalding accidents, namely by the young and elderly, revisions to Part G of the Building Regulations came into force last April.

The main amendments to the Building Regulations are as follows:

• Baths in new homes must be fitted with protective measures, such as a thermostatic mixing valve, limiting the temperature of the hot water.
• A water efficiency standard of 125 litres per day for new homes.
• Extension of existing safety measures to all types of hot water systems (not just vented ones)
• Clear guidelines for where grey water and harvested rainwater can be safely used

These changes now affect all heating and hot water installations across England and Wales, with the most significant alterations to section G3 of the building regulations.

G3: Hot water supply & systems
Previously this part of the regulation only included unvented hot water, but now covers all systems, including:

• Cold water storage cistern changes
• Updated requirements for discharge from safety devices
• Solar hot water
• Plastic soil stacks
• Heater wholesome water
• Vented hot water storage systems

I'm intruigued with this as I raised a similar point ages ago.

I mean the 15L limit only. I have never seen that ammendment

 

[lame plumber]

it got mentioned on my last g3 course, cant remember which way it went, but I dont care as I have the ticket anyhow

15l is still the limit. I updated my G3 last month. It includes vented and unvented but only require separate qualification to carry out unvented works above 15l as it always has been.

Must be one of those things they keep meaning to update then don't for whatever reason. Probably because they can't afford to deal with all the extra dodgy installs that will no doubt come to light. I was told it at my last unvented renewal and back in the day at college that it was going to change

 

[newcastle phill]

Well when you think about it. The 15L limit is simply to seperate boilers with a small integral storage volume. Not a lot can go wrong with them from a safety perspective as they are produced by the manufacturers.
There is a lot to wrong with bad bespoke installs with shoddy workmanship

Thanks gents! I pretty much ignored it as I have G3 but this clears up what I can or can't sub out..
