In answer to your question as to how the boiler needs to run it is best for reliability and efficiency to use a thermal store to supply the ufh. The ufh needs to run at a lower temp / different times than the rads and can be supplied by the thermal store which is heated when the boiler is running the rads, thereby reducing boiler cycles.
You also have the option to heat an immersion coil in the store with pv at a later stage of any heat source available.
