We have no underfloor heating or any on our top floor but it’s working on our middle floor. We have bled the top floor and there is water in the radiators but it’s not heating up at all. We still have hot water ? It’s a heat pump system..

    The heat pump is irrelevant. What is relevant is how is the system piped? What pumps do you have? What valves do you have? How are they controlled?

    So... maybe some pictures or an accurate diagram?

    Is that the only manifold? It looks like the 3 floors are labeled K-H-S? 

    Not sure about that brand actuator, but usually when they're open, the tops rise so you can visually see they're open. In the pic they all look closed.

    If the bottom and top floors were calling for heat when the pic was taken, then it's probable the voltage isn't getting there to open the actuator(s), or it's a faulty actuator(s), or the actuator(s) is not properly seated on the manifold. But it looks like they are. 

    It looks like the power light is lit (230v) on the relay panel but I can't tell if the lights are lit for the zones.

    Do you have an electric meter to test with?

    Where are you located? After the issue is (hopefully) resolved, I'd love to see more pics of the complete system. Heat pump hydronic radiant systems aren't exactly common in the States.

    The place to start is at the manifold and the actuators. Two different -- and straightforward -- tests. First, when a zone is heating, are the actuators which control that zone getting power? And, if they are, are the pipes going from the manifold to the zone getting warm? I'm thinking that there is a control problem here.

    Can a radiant manifold feed enough water to warm radiators?
