[QUOTE="chris_k, post: 354560, member: 1679"] Evening. Ive got a job to price and im after a soloution. I have a flat to wire that is going to have all electric heating / water. Its an upstairs flat with the service head / meter downtstairs. The head has been installed already but we are waiting for the meters. The distance from the head to the proposed consumer unit location in the flat is approx 18-20m. with a torturous route up walls, through floors and ceilings. The spec is to have 2 storage heaters and water heater on econ 7 and the rest panel heaters. Whenever ive done work with systems with storage heaters they have their own board running off the off peak supply. These have always been older properties with older timeclocks. I have seen a couple of newish properties that have only 1 cu but has econ 7 and the whole house turns to cheap rate after 1am or whatever it is. Whats the norm nowadays with newbuild and econ 7? If i have to have 2 cu`s then i will need at least 4c from the meter to the cu`s. Due to the route to be taken it will have to be SWA and because of length will have to have isolation and fusing down for discrimination against the 100a fuse. What isolation / switching would you go for? Ta Muchly [/QUOTE]
