@Carso81 Firstly, that does not sound safe. If "The wall heat up in certain spots if you use two power pointsthat are close to each other" then that is a lot of dangerous power usage.If the meters are that old then you are on a flat rate.Please get your place inspected by a qualified electrician.

They do have a bit of a cost advantage as they have economy of scale, but you still have to spread their cost (and carbon penalty) over the estimated life of the product. So a slight increase of initial purchase price over 50+ Years is a be ...
