My main issue will be I said they could take the gas meter out, so I need to go get a induction hob and of course that means cutting the hole in quartz slightly larger aswell because it’s not standardized .
New hob will be by far the most expensive thing about the switch!
I’ve also found out that in no way shape or form can the cosy 9 condensation drain go into soil stack or grey water waste - I have not had a solid confirmation on this but apparently the volume of R290 means there is a auditable risk of that leaking into drainage system… So soakaway only! Daikins apparently have a no return valve to prevent this.
I have the system here so I will take some internals soon. Box states 4.65 COP @ 8kW. 0.88 KG of R290.20A max current. UPML 25-105 130 grundfos.
I have an R290 Vaillant, but regulations in Germany around that are the same. A Vaillant service engineer confirmed to me that the (minimal) risk of R290 leakage into the drainage system is the reason why the condensation needs to soak into the ground.
