Bear with me as heatings systems are not my strong point.
I have been asked to look at a heating system at a friends house, it appears to be a bodged system whereby someone has modified an underfloor heating system by cutting into the feed to the manifold and placing a couple of radiators in the lounge area and also in an office. They are subsequent owners so we don't really know what goes where.
There were originally six underfloor heating zones, three of the actuators have been removed from the manifold, there are only three wired thermostats, as yet I have not tested where the cables from these go to (I would imagine the existing UFH wiring centre (which just looks like a junction box) It would make sense that the six zones have perhaps been divided between three thermostats?
The whole thing is controlled by a honeywell ST6998 timer which is in a different room from the boiler, the UFH controls are in a different room to the controller and boiler. When the timer comes on everything heating wise comes on.
I was thinking of putting in a Heatmiser UFH8 and 6 x wifi thermostats to control the existing UFH zones to get some control over the UFH zones.
Then putting a thermostatic radiator valve on the two rads, this would in my mind mean that they would only come on by default when heat is called for by any one of the UFH zones. In my mind they cannot be controlled separately as there is not a zone valve.
Does this sound about right?
