Vauxhall Vectra engine not reaching temperature

Car: Vauxhall Vectra
Variant: 1.8 SRI
Model Year: 2006
Categories: Engine & Drivetrain
When driving in traffic at low speed (30 MPH or less)the engine reaches normal running temperature. At higher speeds the engine temperature drops to a level that the temperature gauge does not register and there is a loss of interior heating. The engine cooling system has been flushed and the thermostat has been replaced but the problem remains.

Certainly sounds like thermostat jammed open , but you say you've changed that .Could try bleeding cooling system .
