sounds great but I was think more of a system that can report status
and accept instructions from a PC or other system, the idea being that it
would operate as a stand alone system with overrides from the home
automation/security systems. This would allow (for example) the heating to
be
set back when the house alarm is in away mode and would give more
flexibility than one of the 'standard' systems with regards shedules and
remote operation.
There are two main reasons for retaining a system that will work
without interfacing to a HA system as I see it....first if the property is
sold just take out the interfaces and you have a bog standard UFH
system...second if the HA system is down the UFH will still operate
correctly
although with limited functionality.

Sort of my own!
System consists of 17mm PEX/AL/PEX pipe used as UFH in
screeded floors and same pipe to feed conventional radiators - all via
manifolds with each zone controlled via actuator valves. Each room
with DS18S20 sensors and occupancy PIRs linked to HV. Boiler and
distribution valves controlled via HV outputs and actuator valves
controlled
via X10 relay board.
Downstairs I've fitted a 3 zone UFH manifold and an 8
zone
distribution manifold - upstairs there's a 7 zone distribution
manifold.
Not got all the sensors fitted yet, but so far I'm happy
with the system.
Soon HV will control the heating dependant on time of
day/year, external temp, house occupancy/room occupancy, guest mode
etc... well that's the theory :o)

Ah? Which system are you installing?

I'm installing my own system at the moment controlled
via HomeVision.

Controlled Underfloor heating
has anyone come across an underfloor heating
system which can be controlled from a PC?
Several of the ones I have found
have their own microprocessor control but no way to allow any
external control from your own devices.
