Part F building control notification

[Aaron b]

Hello, I understand that from the 15th of June testing and commissioning of vents and fans is now compulsory and that also since last year any works regarding fans needs to be notified to building control under part F.
I assume that this can be done as a NAPIT contractor registered with EAS. I've had a look through napits Ventilation Certificate, the details in appendix C of part F and the Domestic Ventilation Compliance Guide and the commissioning seems overly onerous and requires specialist equipment. Is anyone here doing part F notifications, commissioning or the full ventilation survey that appears to be required? I'm either thinking of blaming the plumber or offering it as a separate service...

It’s not just water vapour being sucked away. There will be smells, gasses, ahem

You’ll be using that water to clean your teeth…..

Just remember not to swallow.

I think manufacturers should certify and test their fans. They should give a certifcate with the fan you buy to show it complies. It seems once again we are being asked to do manufacturers work. /sigh!

 

[Mike Johnson]

Would that require the manufacturer to test with different ducting systems and length?

It's the installation that is being tested, not the fan.

It's the installation

...of what?

 

[DPG]

...of what?

The amount of air movement. Ducting and room sealing will affect this. The fan flow rate is a factor also

I regularly install inline fans in replacement of ceiling fans. I'm unclear if the intention is for all of this to apply to upgrades or only more major installations. Most fans include a low and a high power mode and the function will be affected by the installation method.

I was speaking to an airflow rep the other day and he claimed their fans are tested with 2m of straight duct but thought others didn't.

I'm sure there will be something in the Water Act that prohibits that, and if not there should be.

Why?

At the very least, recirculating shower water can't be a good thing.

I suspect this is only for new builds, extensions etc. I can't see it being applied to replacements or upgrades in existing buildings.

It's not shower water it's condensed water from the shower extract steam.

Would condensed luke-warm water from shower steam be a good place to incubate legionnella bacteria?

 

[DPG]

Let's face it, the vent should be to the outside.

I assume there will be a fee involved in notification?
