Hi all,
I am hoping to get my house central heating system to the point where it is all controllable via a pc.
Looking around the "Heatmiser" stuff looks pretty good,but damn expensive.
Is there a way I can do something similar on the cheap.
What I want is a way to stop/start the flow to a radiator, using something like the heatmiser valve, http://www.heatmisershop.co.uk/Heatm...e-p-16203.html
by reference to the temperature in that room. (I am not bothered about being able to alter this from within each room so just a thermometer would be ok)
I envisage the pc would know the temp in the room, which it would reference against a set of criteria such as time of day, day of week etc such that just before the kids go to bed it ramps up a few degrees, but then whilst they are in bed starts to drop it down.
Similarly when the main heating comes on via timer, only certain rooms are heated e.g downstairs until an hour before first bed when upstairs can start being heated. Once we are all in bed then no poinnt heating downstairs anymore etc.
Does anyone have details of what sort of system I would be best using ? Has anyone used the heatmiser inline valve - before I saw these tonight I always thought the only thing I could use is a 2 port motorised valve. Do you need a constant current to keep the wax valve above the temp required to close it.
Any pointers in the right direction would be welcomed.
Thanks
Stuart
P.S. Also keen one day in the future to add in cctv pc surveillance with internet alerts, and to connect the alarm system up etc - so much to do and so little time in life !
