[QUOTE="robincls, post: 465980, member: 30323"] Hi there, I'm new on here and just came across this forum on the web, I've been fighting this question / problem ever since I moved into my house in 2013 - so here goes! My house has a three phase supply due to the blown air night storage heating that we have running on the Economy 7 tariff. When the system was put in (~1965) it was set-up as follows: phase 1 440v supply to the night storage heater ONLY phase 2 240v domestic supply phase 3 not connected The timing for the Eco7 rates are managed by a Venner time switch. The problem with this set-up is that phase 1 & 2 are two separate circuits (two meters, two MPAN serial numbers etc). This means two standing charges and even worse I cannot benefit from running my appliances or water heater during the night as the domestic supply circuit and associated meter are charged at the full day rate. Before I contact my supplier I want to understand if such a product even exists that could replace both my analogue meters and the time switch, like a digital Eco7 meter would in a normal single phase house i.e. with the timer and R1, R2 rates all in built? Unfortunately I'm not an electrician so I hope this makes sense? Many Thanks Robin Coles [/QUOTE]
