Gone West

At my last place I fitted a UVC heated with a, IIRC, 650W EASHP. I stored the water at 45C and didn't bother with heating it higher to kill off any bugs.

I've been looking at the Aquinox TS PHE and the file shows flow rates for different kW, inlet and primary circuit temperatures. Aquinox HWM.pdf

If it came from that lot of nests then it was a rook not a crow, still a corvid though. Corvids are listed as vermin and can be shot.

Welcome to the forum. I wouldn't worry too much about feeling like a fish out of water, most self builders do to start with. It's a steep learning curve but we managed to design and build our own Passivhaus without any previous experience. If it's what you want to do, stick with it.

Any pictures? Is it evergreen? The chirping is probably made by house sparrows. Trimming garden hedges is usually allowed all year. https://www.rhs.org.uk/plants/types/hedges/pruning-guide

No I don't unfortunately. After the garage had blown down I just cut the SWA cable, took the CU apart and left all the bits. I don't even know if the power to the garage ever worked as the MCB in the house CU was off and having recently moved house had other things to sort out.

I don't have an issue as such, it's more a theoretical question. The garage that blew down a year ago had a small consumer unit in it and it looked like the neutral to the RCD connected at the bottom but the live connected at the top with the busbar at the bottom as normal. So I wondered if the neutral could go either way round as I've not seen it like that before.

Is the direction of flow through the neutral of an RCD important?

On the Dam Buster bottle I have, it says sulphuric acid (above 75%). It also recommends using a full face visor and rubber gloves. Very effective when I've used it.

Welcome to the forum. Well done, it's a nice looking house. Any more pics?

We found some Dam Buster cleaner left behind when we moved into the house. Very strong but worked a treat. https://directplumbingsupplies.com/product/dam-buster?gclid=EAIaIQobChMIyOvQ-M-F_gIVjaztCh0mGQS1EAQYAiABEgKl3fD_BwE

Thirteen years ago and long forgotten.

I didn't think you could get modulating oil boilers but I've just been told by the heating chap about a fifteen stage modulating oil boiler. Every day is a school day. https://sapphireboilers.co.uk/

Work well with a thermal store if gas not available.

No because IIRC Grant recommend a minimum return temperature of 50C which I think is to prevent corrosion.

Oil in our area has gone from 85.17p/l in January to 68.11p/l today, so a volatile market. At todays price, to match a 90% efficient oil boiler you would need a CoP of over 4 for the A2A HP, so it's close.

If possible I would close the account and have the refund paid into my bank account.

I agree. If it really bugs you, then change it, is my view on things. I was told everything had to be flush.

I'm not sure about that, but I've attached the PDF. The P1000 filter is supposed to remove water hardness but it would probably be an expensive way of doing it if your water hardness is high. Our hardness was very high hence why we had a softener. brita-tapfilter-instruction-manual-EN.pdf

I fitted a water softener on our mains supply but fitted it after a seperate supply for drinking water and toilet cisterns. I fitted a water filter under the sink supplying a three way tap. In the first picture, the manifold with the white taps is hard water.

It looks to me like a very similar finish to the white wall.

When I was doing my metal shed at the last place I found a website that showed all that sort of detail. Says it should be vertical. https://www.mepits.com/tutorial/497/electrical/electrical-earthing-grounding

No only done one self build and that was enough 😀.

That's right, thank goodness 😁. The PHPP does do overheating, but it was just a comment about BC being able to be flexible if they want.

Mine was LPA BC.
