Problem
When part of the house is warm and part is cold, the heat pump itself usually isn't to blame — heat distribution is. The usual response is to raise the curve for the whole house, which is an expensive way to fix one cold room.
If the nearest loops take all the flow, rooms further away stay cold. Setting the underfloor manifold's flow meters according to the design solves most cases.
A radiator cold at the top and warm at the bottom indicates air. An entirely cold radiator indicates a closed valve or a blockage. We recommend checking these before raising the curve.
We don't recommend it. That raises consumption for the whole house. Balancing the system is more effective.
It's usually a few hours of work. An exact price comes from a quote after describing the situation.
