After writing a first review, that has since been taken down, I am hoping my second attempt to review will be left live for other consumers. The Elnur storage heater i bought is an adequate product but the programming functions are very poorly set out. The heater sent out was defective and would not store charge. Both Elnur and Merinal (trading under Storage Heater Sales on the internet) had shocking after sales service. A contracted service repair technician was eventually sent out to replace the circuit board and display, after a fair amount of time wasted chasing the whereabouts of the replacement parts. I would not recommend either the Elnur storage heater or Merinal/ Storage Heater Sales.
