Having said that, why is this a factor when trying to establish a comparison between two similar days in different seasons? Is it because the daylight time is less?

Sorry. kWh.

Thankfully not ? Chimney guy a no-show this afternoon. Sigh.

Thanks for the great insight about the straightness of the pipe. I have a hatch that may provide me with access. I’ll inspect it this week.

On a comparable days, with blue skies and lots of light, what is the main reason why in summer the panels produce their full potential, while in November they do half? Is it the position of the sun in the sky and its consequent angle to the panels, or is there more to it? In our case, we’d do 6kW in summer and only peaked at 3.5kW today. Curious.

We have two new wood burning stoves that use that chimney, so we are definitely going to have to keep the chimneys.

That’s a handy skill set to have when working high up. Did you just strap the tools to your backpack as you scaled up the side of the house? ?

Agreed. We have someone coming today. They’ll get on the roof and look for the cause. When we rebuild, a DP will definitely go in.

Yes, it does. I was going to connect the new vent pipe to the old one. Would that work?

And connecting/extending/running the ventilation pipe.

That would be a consideration... maybe if we can temporarily plug the cause of the water making its way into the house, then that buys us time for the summer, and get more second opinions.

It’s got to move to the left, into the new shower recess we’ve made (where the stud is). I’ll also be buying a better quality vent.

It’s ceiling and we’re moving it further away... There’s limited loft access above the ceiling in question. Photos coming shortly.

Hmmm. Not what I wanted to hear. So it might be worth getting done. Sigh.

We are going to have to move our bathroom ventilation fan as part of our master bathroom redo. It’s going to have to move about 2 meters from where it is. I don’t want to destroy our ceiling to do this. Any clever tips or suggestions?

Right now I’m just trying to figure out whether wet, porous bricks can pose any further damage to the house in general... that’ll make up our minds. There’s also always the option of waterproofing/treating the bricks to prevent the water from penetrating them as mentioned earlier. I guess that the rebuild is the better fix. thoughts?

Clever idea on the measurements. Second opinion is always useful... most of these guys are saying that they can only come out in Jan due their busy schedules.

We had a roofer come out yesterday that looked up at the chimney from the ground - he also thought the brickwork looked saturated and wet, and has quoted us £1900 + VAT to rebuild the chimney - we would need to supply the bricks. Given that we’ve not had a leak or any water making its way into the house via the chimney before (and we’ve endured heavy rains before) I’m not sure whether this required, and whether the water making its way into the house is coming via a potential hole or shoddy lead flashing. We’re going to have that inspected tomorrow morning by a pro. On a closing point is there any other threats a damp/porous chimney poses to the rest of the house in terms of damp, mould, etc?

Is the 9l/min metric determined by the shower head?

We have decent water pressure in the house, which does suffer a tad when you’re showering and someone else opens a tap. That aside, is there a metric for showers that we can look for that shows the amount of pressure a shower head can generate?

Now that all things have been weighed up and considered I am very much on the same page as you.

Nice piece of kit. 2k is well over budget for us though. I guess it’s an investment in the long-term.

I’ve looked at the height this morning and I reckon it’s 8-9m from the ground to the gutter.

On the subject of the moss on the roof, is there any of dealing with it other than scaling the roof?

I have a fear of heights, so gutter clearing and roof tasks are my wife’s domain... I would like keep her around, so I think we will pursue professional assistance with this one.
