hi,
currently the immersion is wired to normal supply, however there is second consumer unit connected to economy 7 meter, customer wants to use economy 7 for heating the immersion in evenings, the hot water cylinder is fitted with a single element on the bottom.
So my proposed solution
1) Is to feed a new wire from consumer to economoy7 timer this will then heat tank between 11 - 7 at off peak rate and then can use boost to warm during day if required.
2) Is to feed new wire from consumer unit to change over switch with normal feed and economy7 feed then they can choose between feeds
any other suggestions appreciated
