Absolutely, and purchasing of gas when supplies are cheaper...

Yup. And if proven to be successful will be a game changer! Thats why I put as much PV in as possible..

Er, I was thinking people should wear it.😂 But on a serious note our home produces more energy than it uses in a year, just not when we need it. We need good energy storage.

In the UK 45-50% of energy is used for heating. What we need is more sheep. We can then produce more wool.

Almost ditto. I run 32mm down first vertical into a 32 to 40 collar and 40mm swept bend and pipe from there on. Also, always use swept bends the whole way.

Oh and whilst you at it I would consider the 80amp meter might need changing....

Hi Everyone. I felt it was a good time to see how these things are working. Seems to me not too bad!

Hi @JohnMo We live nearer the equator than you so more sun...

This weather should indicate if the ASHP assumptions, calculations, designs, installations, running and power connections are up to requirement! Outside temp 5.4C Buffer tank temp aim 39.4C Internal temp 22C I wonder how Norfolk is doing after -12C over night...

Hi @SteamyTea There is a certain joy in knowing you paid once to reduce your energy use and the effect lasts for years! Every time the sun comes out a little thought in the back of my mind thinks about our hot water tank warming.

Yes a vertical Wadi.😂

Hi @Pappa On viewing your photo of the rainwater pipe from the roof there is green way above the lower bend of the down pipe. I would be inspecting the gutter down pipe outlet to see if there is any obstruction. Secondly I would also inspect its operation in the pouring rain to see exactly where the problem lies. Me thinks that the problem is starting higher up....

And fill the old waste pipe hole before you get rats! And around the new waste pipe And any other hole that vermin can enter.

Thanks for that.

I didn't say I use weather compensation so auto stepped temperature targets.
