No, you can DIY the lot. I know of a 100% DIY install with a G98 signed off by the DIYer. DNO accepted it. It's not legit as it should have a spark test and certify but it's seems DNO doesnt care/notice. Â Other DNOs may be more scrupulous but I think they're likely to be pretty appreciative that someone's bothered to notify them regardless whos signature is on the form?? 1 Link to comment Share on other sites More sharing options...

Thanks, so basically it's the same as most wiring then- don't be an idiot! Â And the requirement to get it done by an MCS company still stands if you want to get paid for export?

I'm sure someone posted about there being another outfit that does the certification but can't remember the name. Link to comment Share on other sites More sharing options...

Flexorb is the alternative outfit. Octopus wont accept them though, the decision whether or not to accept is down to the supplier. Link to comment Share on other sites More sharing options...

You set you target temp for AC, independent of what the DC (PV) does or achieves.  So completely fulfills what the OP asked for. PV hot water but also can be charged by E7 if required.

OPs mentioned "feeding the house first" and repeatedly said grid tied?? Having the PV hooked up just to a diverter seems a waste as theres no where for the PV to go once the DHW tank is hot, or is that not how it works??

That immersion looks good but it's really really expensive. I'm thinking the Cool Energy DiverTech will do the job at a third of the cost. Link to comment Share on other sites More sharing options...
