I had some fun (not!) painting the rafter feet in black, and the underside of the soffit board in white...
the guttering is now in place, with a nice piece of temporary plastic downpipe until the wall is ready to receive the cast iron stuff...

Under the eaves...

Scaffolding gone, rendering finished...
... for now anyway, before they come again to sort out the side extension...
(PS: notice the nice weather, it's hot, it's sunny, it's lovely, it's beautiful !!)

OH by the way...
Although the boiler is not functioning, I was happy and proud to be able to provide Emily with a hot bath (it will be mentioned that she even had to add cold water to it !)
It took about 45 minutes and about 12 kettles boiled and two pressure cookers full of boiling water, but I did it !
Let's see
our boiler is 32kW and would fill the bath in 5min + 6min of initial heating for the 50L hot water store (when you first power it on).
that's 32 * 11 / 60 = 5.86 kWh of energy to heat up the bath
kettles = ( 3kW + 2 kW (we have 2 at the moment, thankfully) * 4 min * 12 times) / 60 = 4 kWh
pressure cooker = 2 * 15 min * 3.5kW for the gas burner / 60 = 1.75 kWh
yep, 5.75 kWh total, about the same , it makes sense :-)
However, obviously the bath level was quite a bit lower with method 2 than when we use the boiler, and also, when you fill a bath in 40min and you pour the water in a cold bathtub and in a cold bathroom, well a lot of energy gets lost in the air... That's why I used about the same energy to heat only 2/3 of the water we would have poured using the boiler.
I suppose it is very nice to have these mighty 35kW available on demand though, so in conclusion, a house needs a boiler, really...
(Emily will be pleased to hear my opinion)
(And I did not even mention central heating, which the boiler happend to take care of, as an added bonus !)

Testing the old radiators for leaks
You will be pleased to know that two of them tested so far are perfect (and one more to go)
I tested them at 5bar, which is the pressure at the tap in Chelmsford.
However, like with any pressurised central heating system, they will operate with a hot water pressure in the region of 1.5 to 2.5 bar, so plenty of confidence i have

Plasterboard in the bedroom...
Tomorrow they will plaster it so it will look nice and traditional
