Heaters blowing cold air.

Hi there I've just had my ware pump and thermostat replaced and a flush done on my mini one 2003. There was heat from blowers when I left the garage but only slightly warm this evening. I Thought the problem was fixed. Anyone have any ideas what the problem is? Thanks

Probably has some air still in the system that needs purging.
