Bear with me. Hopefully I'm worrying about nothing. Have had evohome for a few years but a new kitchen extension with UFH has left me confused.
I've been running up the UFH in short bursts recently as the screed does its final drying (its been down 6 weeks). The 'problem' is that when the UFH is running (currently set at its minimum of 30 degrees) there is barely any temperature in the UFH return pipework. This appears to keep the boiler almost constantly firing whilst water also circulates our general radiator system. Doesn't seem quite right to me, even though heat is reaching the manifold and loops.
As a background we have an unvented cylinder and radiator loop and in an S-plan arrangement. The UFH heating loop is tapped off the rad circuit and is providing 65 degree water to the manifold.
We have the kitchen set up in evohome as a zone controlled by zone valve with Y87RF thermostat. Tweaks to the setpoint correctly open the UFH 2-port valve, which itself runs the UFH pump and heat is moved to where it needs to be.
Not sure if this is right or not, but when the kitchen calls for heat, both the 'UFH' BDR and 'Heating' (radiators) BDR both light up.
Do ask away with questions if thats too vague to answer!
