RCD protection for existing heater circuits

Hi 

Customer wants existing storage heater circuits moved over to on-peak. He is having some fancy eco heaters that i am not fitting installed by another party and they, as far he knows, only require an on-peak supply.  The existing fuse box does not have rcd protection. If i change it over will it need RCD protection.( i don't think it does as i am not changing any circuit wiring) i appreciate it would be a C3 on a report as it is because of cable depths.  The cables obviously are already in place with 20amp switches on.

Thanks

  • Would this be the sort of eco heaters that use the same amount of electricy as normal heaters, produce the same amount of heat

    Probably not.  Traditional storage heaters while 100% efficient of themselves do have significant inefficiencies when it comes to their basic job of keeping the house warm. Old ones would take pretty much the same amount of energy to charge up overnight regardless of how much heat was actually needed to keep the house warm the following day (depending on the weather) (OK there might have been some manual adjustment  .. which nobody used day-to-day), they kept on kicking out heat even if people felt too warm and opened a window and so on.  The "LOT 20" versions use a number of tricks to significantly reduce the energy consumption while still keeping the place comfortable. Most off-peak systems charge off-peak rate for the 24hr circuits during off peak times, so as long as the timing is right, the benefits of off-peak should be kept, while still having power for control (and possibly a boost) during the day without the need to run a duplicate cable to every heater.
