Vaillant - Downstairs radiators not getting warm
@jamespa thanks James! Ive read through the manuals and found the Eco DHW setting on the Heat Pump controller. I've set it to Manual to see if that gives me the energy in tonight charge cycle.
@samiebon1 our DHW gets to 48C with a heating temp of ~55C within ~ 45mins but it’s not usually empty (residual ~35 in bottom third of tank).
The layout of our house meant that some upstairs radiators had to be virtually off to ensure the flow went on to downstairs or else the bedroom radiator took all the water.
2kW + Growatt & 4kW +Sunnyboy PV on south-facing roof Solar thermal. 9.5kWh Givenergy battery with AC3. MVHR. Vaillant 7kW ASHP (very pleased with it) open system operating on WC
When adjusting lockshields its worth bearing in mind that some have a tiny range over which the adjustment makes any difference. Sometimes half a turn or less takes it from fully closed to fully open. This makes getting it 'right' quite tricky.
If you want to know more about this view Heat Geek on 'valve authority'.
