Corsa heater problem

The heater in my Vauxhall Corsa only produces cold air and I don't understand why this is.

The electric valve between the engine coolant pipes and the heater matrix has failed. You probably have not used the heater all summer. Now you try to open the valve again it has stuck.

Solid and decently equipped. Reasonable handling and some frugal engines.
