We decided to change our old storage heaters after sending for the information and then having a consultation from the advisor and finding out that the sytem works more like central heating with the wireless controller being set to turn the units on and off at your desired times and also to a set temperature. Everybody that we delt with was very friendly and efficient. The Installers arrived on time and fitted the heaters very quickly and with no fuss or mess. We have only had them a couple of months so have yet to find out what savings on elecricity we will make but are very pleased with our purchase. They are not cheap but it's the old saying "you get what you pay for"
