So you have a 110v AND a 220v supply in your homes ??? I don't get that. Why not just have 220v everything ???

I think I'm right in saying that hot water tank systems like mine can no longer be fitted in the UK, the legislation says a combi boiler must be fitted which heats the water on demand. My house was built just before the legislation came into effect, and the houses that were completed towards the end of the site build have totally different heating systems in them.
