ah. the rad vent is the bleed valve.....got it. last night it left it at 2.6 bar, this morning it was at about 1.6, and did fire up when I changed the thermostat. It's humming along "contentedly" at 2.2 now. I'm collecting numbers for when I call-out. I've got about 40L of oil left in the tank (yes it's low) oil was actually due yesterday but whatever logistics they have, should be arriving by the 20th. I think I'm using approx 2.5L per day
