You should also consider using a proportional valve rather than just
ON/OFF=
.
I have some ON/OFF ones and I still get oscillation around the setpoint due
to retained heat (forgotten the tech word) within the radiators. (I was
basically using zone valves)
I have researched a few inline / TVR replacement options =96 You can get
plain ON/OFF down to about =A325 but proportional all seem to be circa
=A36=
0
plus. There is a very low cost device (TVR replacement) that works on
thermal expansion =96 basically you apply voltage and it heats and expands
=
but
the response time is quite slow.=20

Does any one know where I can get solenoid valves to bolt on to my
radiators, so I can use my home vison i/o and relay card to drive the
heating room by room. The only ones I have found are ?50 an peice.. eekk .
