Re: Impact of London's ULEZ expansion on air quality

It is both PM2.5s and NOx levels that count, for instance our car is way cleaner than the limit for PM2.5s but above the limit for NOx so it wont be compliant.

Re: Solar thermal for hot tub

I think the unanimous opinion is that PV and a diverter beats ST these days. There are also some intrinsic problems with ST. Eg: if the water boils it can be dramatic, all liquids leak eventually, all moving parts (pumps) fail. However if you really want to mess around with ST I don't imagine it'd ...

Re: Backpedalling oil scum

Now would be a good time for GOVT ( there's a joke) to levy a pretty beefy windfall tax on these extraordinary profits. Or the GOVT could offer an alternative by investing a proportion of that profit into renewables. We need to heavily persuade the big oil companies to move sideways away from oil o...

Re: Shedhenge

I haven't read through the manual completely yet, how do you designate any particular battery as master, I don't think I've seen any reference to that? It's the one with link 0 port empty. Thanks that makes perfect sense looking at the cabling and ports. I have read the manuals now, but I cannot fi...

Re: Shedhenge

Thanks chaps, I haven't read through the manual completely yet, how do you designate any particular battery as master, I don't think I've seen any reference to that? Six Panels are all mounted up on the woodstore and shed, wired up and connected (almost) to the inverter in the loft. Good fun was had...
