    I think I replaced all of my rad valves with the Drayton RT212 and found they fit the Conrad / HouseHeat / FHT80 / whatever-it's-officially-called system very well. See...

    Personally, we went for the Homeheat system and it's been okay - there are some niggles with it (the batteries don't seem to load the quoted 1 year on the valves - nothing like it!), but on the whole...

    Incidentally, if it's any help, I think all of our TRVs that we fitted were Drayton RT212s, which worked fine with the FHT stuff:

    Hi Longview,

    I'm not an electrician, but I believe you CAN do this - all that the boiler connect (and other timers) does is to open or close a switch to allow power to flow into the boiler.

    Hi Pheonix,



    I was surprised at this as well - the devices broadcast their addresses, so they ARE discoverable. However allegedly they'll only talk to one device at a time, so as soon as...

    Alternately of course you could put your thermostat to "MANU", and scroll up to "ON" - I believe this should always set the actuator to 100% regardless of the measured temperature?

    That's right - the boiler should circulate water for a few minutes to prevent the water temperature continuing to go up in the boiler while it's cooling down.

    Re the pressure valve, if you haven't...

    I found the same with all of my radiators - they seem to get to full temperature when the valve is only 60 or 70% open, which makes sense as all my rads are fed off two zones, each of which is 15mm...

    That sounds odd - I believe the first thing the actuators do when you attach them to the radiator is work out the correct positions for 0% and 100%.

    The actuators have quite a wide range of...

    In case it's any use, when I fitted my FHT setup, I also replaced all the central heating plumbing and as part of this fitted new thermostatic valves throughout.

    Even though all the TRVs are brand...

    Just to add a bit more to this, I have a suspicion that the FHT system is being "intelligent" - in other words, it's trying to work out things like how long the room takes to heat up and how quickly...

    Can I just enquire, how much would you want for me to buy / borrow this off you for a few weeks?

    I'm using a CUL device to connect to my system, and I'm concerned that this may allow me to bypass...

    The FHZ1000 is a central control unit that I believe allows you to from ONE unit control all of the thermostats centrally, if you're happy to manually program each room, and if you're going on...

    Hi there,

    I've had 7 of these things running in the past, and for some reason there does seem to be a massive noise difference between the load ones and the quiet ones! Fortunately for us, the...

    Also, try sending...

    Good stuff, look forward to reading it!



    This was (and still is) one of my biggest frustrations - the FHT devices, providing you've got the right type, do send the measured temperatures, but...

    Hi Jon,

    My advice would be if you're not IT literate, probably go for the FHZ1300 as it comes with some software as part of the package (not great software from what I've read, but it's a complete...
  22. Conrad / Housetech / FHT Security Concerns

    Hi all,

    Forgive me if I'm missing something, but has anyone else here got a FHT central heating installation, and had the thought that there's no security on these devices?

    For example, I can...
