I have installed some new stg heaters dimplex creda etc but early days to see if they are more efficient. cannot imagine the electrics to last.
ONE SUPPLY....I have called tech support on a few manufacturers recently and Dimplex did say that they are working on one supply to support the existing E7 off peak stg heaters. Link off peak to peak and guarantee invalid......However, ELNUR support the linking of peak to off-peak. Just swap the E7 circuit to peak/main CSU and it is good to go....BUT programming their heater can be a PITA.
