Im coming up to a maintenance job which is all electrics on social housing.Im ok with everything but the job does entail storage heaters I mean yes I have done your basic twin to a spur with the storage heater on the wall, but people have mentioned economy 7 installations.Are there any more ways of doing storage heaters?It would be a great help if someone posted drawings(wiring diagrams) of economy 7 storage heaters,plus any other ways of doing storage heaters that I need to be familiar with thanks Ryan
