No slots and pack down to 38% for 10am.

Nipped out and spent 1hr clearing accessible panels. Went from 9W incoming to over 800W incoming. Chuck that into the HP and it's 2.5kW of heat.

EV is back in the mix running the washing machine. By the end of the morning I'll know how many miles per wash cycle. :D

Heard from the 3g guys last night. They'll be over next week to take final sizes and template the triangular windows. They even spoke about ordering the windows soon! :o

Mostly for my own reference or i'll forget. An average days consumption with no ev charging.

Today before I started topping up the battery in the afternoon.

It turns out it's 10 miles per wash cycle. :D

Had a look with endoscopic camera and the expanded foam did its job.

Got the phonecall from Travis Perkins and hotfooted it round there for the swag.

Job is progressing well, only blip is a well fitted midrail so had to cut in at top and below midrail

Vermiculite flowed in nicely and we got two vertical columns (4 compartments) filled and topped out with loft insulation.

Image

Here's the instant difference maker the insulation makes. Comparison is between a filled and an empty compartment. Minutes after filling.

More fun tomorrow, 14 compartments to go and the excess vermiculite will go into the loft.

I do like vermiculite as it has no detremental effect on pvc cabling used it once, to fill a void above the living room cupboard and the ceiling, was just rewiring at the time so had floor boards up and was able to pour in from the top.

Always thought it would be ideal behind lath and plaster

I wonder if pouring in vemiculite will stop the rats travelling between the granite and the plasterboard? Rats all gone. Yay.

On a more serious note I wonder if it would work behind granite walls or should I let the wind continue blowing to remove moisture. So far any wall I've opened has had dry timber and I'd hate to disturb the equilibrium.
