Hi Guys
Will try to respond to all questions -sorry if I miss any answers
CH is on for about 1.5 hours in the morning then about 7-8 hours after 16:30
Sometimes left on during the day at 18°C
HW on for about 1 hour/day
Currently paying
£0.03359 per KW ex vat
£0.3088 ex vat standing charge / day
No higher rate for quarterly useage
working out at about £1.58 ex vat @ 38KW per day
Will monitor usage & do understand you can't really compare day to day useage due to temp differentials but was comparing the usage with a similar day with similar temps outside with settings at 18KW & the new lower setting
System is Open Vent the Cylinder stat is set to 60°C
The boiler Rad water temp is set to 58°C the temperature is fine rooms temps are about 21°C to about 23°C upstairs
When I had the Rad water temp set too high it was very uncomfortable
D2 is set to the default 20 minutes
