  • I wish I had specced humidity sensors and enthalpy unit.  As it is I have had to pay vat on enthalpy as bought afterwards and at nearly £1000 not cheap.  I dont have the sensors as we didnt wire for t

  • Yep... the reason is because humidity varies and you can’t have a “standard” humidity at which to boost. Most people have used motion systems or just a link to a light switch is enough to make it boos

  • I have found that no boost is needed in shower/bath rooms. I just leave the flow rate at the same low rate and there are no condensation problems.

Looks very tight to the roof ..? Are you able to get bends and silencers etc on that ..??

Yes - should do . Was told by bpc that I can fit the flexible silencers first to Mvhr - which should give me enough ‘bend’ to be in the loft space .

are those tiles all in neat unbonded rows?

Sigh yes ! . Even this ‘proper’ roofer queried why they were done like that ...

Yep - you did ....

Original roofer ( if that is what he was ) said “it didn’t matter “

You do see a few roofs like that with the flat tiles perhaps the interlock detail means it's ok who wouldn't want bonded though?

My neighbours house is tiled with flat tiles that have a line down the middle, they are meant to look a bit like slates and for that to work would need to be offset by 1/4 of a tile from the row above. But they are all laid with no offset at all.

Anyone else have issues with the supplied duct seal ? . Doesn’t seem to hold joints together at all ! . Thought it would be like solvent weld but it’s not . Next day with the slightest bit of strain on the joint it comes apart ...

I like to tape around the outside as well with the foil tape.

Me too, in fact I've relied on duct tape to both join and seal all our sections of rigid duct. 

 

There's a good reason that duct tape is called duct tape...

  • Author

Oh yes; I was going to foil tape all joints anyway. Rather make sure they aren't coming apart before I do that though...

  • Author

BPC say that the duct seal stuff remains plyable for a few days before setting. I'll keep to CT1 for now.

Surely ct1 is ott here. What about all purpose silicone

Below ground ducting complete . Think i’ll Add more support to some of the pipes . The fixing clips don’t seem especially strong . Ground floor now - should be easier . Tricky doing long pipes on your own as I have no friends ??
