My flat has unidare storage heaters model WMS712N. All but one were working nicely on an overnight charge. Now all of them have decided not to charge up. I am not doing anything different. Input setting is 4. Might be older model as input and output dials have slots. I am due to have electric meters changed would that have anything to do with their demise. It's getting a bit nippy. Will speak to landlord. Just wanted to check problem out first.
