Daz I have the battery to battery charger or inverter from them m8,I’ve had a frost stat feature for 12 years 😂,I can strip 1 down and replace it all I just can’t be bothered anymore my Mrs has had enough of me messing about outside for hours stripping bits off and replacing them she’s bought me another 1. I also want it to look nice when I open the back doors all nice and shiney,I’ll only end up giving to the Taxman in 18 months. So yes I’m getting a new 1 m8 but I’ve had hot water for nearly 13 years now. 🙏
