[QUOTE="tudor85uk, post: 526683, member: 35015"] Hi, We have an EU setup in the house. Our hot water tank has the two thermostats, one for off peak and one for peak. Has bee. Working fine untill a few days ago. Woke up to see the smart meter registering 3.5kw in use where normal is none in the morning just before EU stopped. Went to have a shower and the water was boiling hot from hot and cold taps. Investigated the cold water tank in the lost and this felt hot to the touch also. So turned off the e7 switch and waited a few days for it to cool. After some further tests it appears the the E7 switch is heating tank as per normal but not cutting off and just continuously heats untill the E7 stops in the morning. Has something stopped working in the thermostat to stop heating when hits a certain temperature? [/QUOTE]
