Has anyone had experience of the HouseHeat system from www.heating-intelligence.co.uk? I have been looking for something to control temperature more efficeintly in our 4 story house. I have been considering the CM zone system but it looks very expensive, this system is much cheaper and appears to do the job but it would be good to get some feedback if anyone else has actually used it. I am guessing that as more players enter the market so the price will be driven down.
