    I installed Evohome in December 2014 and did find my gas consumption dropped. Mainly I suppose because my house was not unnecessarily heated because the thermostat in the hall I then had thought it all needed heating. Having the individual control for each room is much better. Like HenGus though I share the concern about the ease of operation. I am in my 70s, I have no issues with operating Evohome or other remote controlled systems I have installed, but my wife has no interest. I think at the very least Honeywell should have, still can, design the app to be easier to operate for the non technically minded. I am sure those designing these things never stop to think of the real and more common end user.

    Like G4RHL, I've experienced a drop in consumption - in my case oil - since installation. How much of a drop is obviously down to individual circumstances and, in my case, much is down to a '60s house with large windows with the ridge aligned roughly north/south. Here the issue was heating the east-facing rooms where there was any hint of sun poking through the large west-facing windows in the hall where the thermostat lived. So for myself, I calculate that I'm on a six/seven year payback and as such could justify the installation (which I did myself) purely in financial terms. Nontheless, it's the enhanced comfort and convenience that makes the system pretty indispensable in my eyes.
    In this thread, but also in others, I've seen opinions voiced regarding a couple of areas with which I disagree. Firstly, on the dreaded question of optimisation, my experience is that it works brilliantly as far as the "early on" is concerned and I regard this as one of the best features. The "early off" I must admit that I don't use as I'd rather spend a few pence on heating than experience a premature reduction in temperature, although that rarely occurred. Secondly, in respect of the ease of operation of the system, while the app may take some getting used to (and if the Android version asks me for a name/password again, I may have to bill Honeywell for a smashed tablet), I find the controller entirely straightforward. As with all these semi-technical things, you will always get a group of people who take a perverse delight in their supposed inability to operate these things. It's funny how you run into those who say that they were never any good at maths but very rarely those who profess a lack of facility with English.

    I feel the same way, and I'm in my 40s! Fabulous in terms of comfort, extremely frustrating in lack of reliability.

They will tell you parts are no longer available. My boiler is 20 years old. Parts are still available. I have just bought a new fan that Iíll install as judging by the sound change of my existing one it is on the way out. My own service people always tell me to keep the current one as long as it works. I shall wait until I really have to change. It will then be an Intergas boiler.
    Oh I'm not expecting the fuel savings to pay for the cost of the replacement! But it would be nice if some of the cost was offset. My main concern with a ten year-old boiler is that it will fail at the worst possible moment (middle of winter or when I'm away) and cost a fortune in emergency repairs. Replacing it is equivalent to some preventive maintenance.

    Interesting. Installed mine in August 2014. Never had to reset, never had any comms problems. It's just worked flawlessly.
    Unlike the app of course. Although a lot of that looks as though the problems are at the server end and not with the app itself.

    Had some hick-ups myself lately. At one point I found that the clock on the main unit was 20+ minutes behind. Did need to reset the main unit another four times in the last few months to make it open the main valve again.

    I'm on city heating and it's hard to translate Joule units into cubic meters (someone mentioned kWh at the start of this thread???). I don't actually have decreased usage as far as I can tell though. But I do get a lot more comfort, which as a home worker means I don't have to put on an extra sweater and there is no more stiff fingers. One downside of the system as far as I'm concerned is that it is not aware of the fact that I do not have any startup costs when opening the main valve. Being limited to a maximum of twelve switch points per hour on that main valve essentially just limits the comfort that the system could give me.

    Over all I'm still quite happy with the system and it turns out that resetting it is extremely easy with this particular version as I only need to connect it to an unpowered base station, which is something I can explain to any non-techie.

    I have no issues with reliability. Not since I stopped playing with it!

    When it fails don’t panic. Mostly parts are available and usually simple to replace yourself. If messing about with the gas supply then it’s a no as then the regulations in the U.K. dictate you have to be registered to meddle. I thought I was Corgi registered because I had Corgi cars to play with as a child but apparently that’s something different.
