Evnin' All,
at today's first job I came upon a strange thing, well for me anyway. A house has economy 7 storage heaters, no gas present. The Economy 7 supply is controlled by a loud buzzing contactor that makes a big bang when it operates. It is situated near to the meter but is controlled by a simple 24 hour time switch that might as easily control an immersion heater. The time switch can be altered by the house owner, as well as being manually turned on and off.
Why this arrangement, and not a proper Economy 7 timer switch or teleswitch.?
