I'd check to make sure the system is fully bled first. Might also be be worth checking the thermostat. Hope yours is just one of these. Top hose pressurising and becoming rock solid and the heater blowing cold are all bad signs.

The cooling system will always be under pressure when hot, only when it's cold and the top hose is pressurising should you worry.

Check rad is getting warm all over and check viscous is working properly as well...

Only 20psi max.

If you can't squeeze the top hose at all (hot or cold) then things are looking bad.
