About testmatch

Many thanks for your helpful reply. We have a smart meter. Are the these dumb meters on the switch board between that and the unit. We have 3 of them.Kind RegardsGrant (testmatch)

Hi, We have a Unidare heat bank which under the old J tariff system heated at night hence the heat being released during the day which it was designed to do. With this controlled load plan they heat up slowly during the day and release heat over night. This is opposite to what we want.Please how can we rectify this otherwise are these units are now obselete?ThanksGrant
