Elnur automatic static storage heater works as expected. Input set to 5 and we open the output in the evening as the primary heat release keeps the chill at bay until home from work. Needed cord to install. A bit of a challenge if you ain't got the skills. Rang to ask for delayed delivery until a time when I knew I'd be home. Was told someone would call me back in 10min. I rang back 30min later after no reply! Was told delayed delivery had been arranged. It hadn't....it turned up the next day....had to be received by a neighbour. On the upside, installed and used straight away. Nice 'n' toasty. Will need another one for open plan living-dining space in mid winter.
