Vaillant Ecotec timeswitch 140 - I am freezing

[single]

Just had new boiler installed, started off with no timeswitch! paid another person to come and fit with a thermostat. Simply cannot get the heating to work either manually or on timer.
The filling pressure guage is permanently in the red area, is this what is stopping me having warm radiators?
I am so fed up, only been in the house for 2 months and EVERYTHING possible has so far gone wrong. Any suggestions welcome, trying to sit at my computer to complete UCAS applications for my students and too cold to sit!

well it ain't gonna help

check the filling loop ain't open then bleed a rad to get the pressure down
