Could new piping save money?
So I've got microbore pipework, and I've seen that replacing radiators does indeed mean you spend less on the new ones, at least in pure running costs Though I'm not sure if that'd be the same for pipework?

Solax vs Libbi batteries
The Solax batteries "work with Octopus" but so does their inverter Surely if you have their inverter, it doesn't matter so much that their batteries work with Octopus? Libbi afaik doesn't. Am I correct in thinking that it doesn't matter as long as you've got an inverter that "works with Octopus"?
