    Didn't realize we were talking about electric baseboard heat. Thought we were talking gas forced air

    The temps have dropped even more, but the pattern is still about the same. It costs +3 hours to heat a room back up. I'm seeing a 40% savings if you turn the heat off in a room for 16hrs. That's not really possible in all rooms though.

    If you google ashrae guidlines for setback temperature, it is about 17 degC for setpoint, apparently this gives the best recovery ratio vs cost savings.

    cheers.

    The numbers are in and my 4 Sinopé thermostats paid for themselves in the first winter



    Sinopé Starter kit + 2 additional thermostats: $402

    Total hydro cost Oct 15 - Apr 16: $1076

    Total hydro cost Oct 14 - Apr 15: $1558

    Difference: $482

    There are many factors at play because every winter is different etc, but I think the biggest factor was my interest in reducing hydro costs. Before it was a chore to manage 8 thermostats individually and if I rushed out the door and forgot 1 there was no way to check or adjust them remotely. Now I enjoy turning the heat on from my phone on my way home with a single touch. Similar to web banking, the web is the only way I adjust my thermostats now. The best part is that the thermostat times are synced automatically based on your postal code and daylight savings time is automatically adjusted like on any smartphone/computer. I used the web interface all winter with no sign of glitches

    They have some new products out that I'm really interested in such as the smart light switch that can simulate presence and be scheduled based on sunset/sunrise. I live up north so the sunset/sunrise varies drastically throughout the year such that if I leave for a month or so my scheduled lights are out of whack coming on way to early or late etc. You can demo the light interface now and there are some neat settings, such as double press in the master bedroom turns off/on all lights or syncing switches etc. I doubt these switches would pay for themselves in hydro savings, but they do add security and convenience if you are often away

    That sounds about right from what I saw. If you set too low then you just wasted too much heating back up

    That's really impressive, especially in a province where electricity is so cheap; I would have thought they'd take years to pay for themselves!

    Electricity is really cheap but it also averages below zero half the year where I live. Last winter was especially cold so I won't give all the credit to the thermostats, but I'm happy so far

    I love my Ecobee thermostat. The thing that I like the most is that it has remote sensors that detect both motion and temp. I generally set the temp lower (in the winter) during the weekdays. On days that I work from home, the sensors know that I'm home, and it will adjust the temp automatically. You can also use the sensors to determine when the furnace turns on/off. For example, in the summer, the upper floor is generally hotter, and if you like to be cool when you sleep, you can tell the Ecobee to use the remote sensor's temp reading instead of the temp reading on the thermostat itself for the night. It will cool the house until it reaches the desired temp in the bedroom(s). Your lower floor will be cold, but you get the desired temp for where you are. During the day, you set it back to normal. Call me lazy/forgetful, but some things in life are worth paying a few extra bucks.

    Yup

    I'm still very happy with my Sinopé setup a year later. I like that they're a local Canadian company and the quality/price is very competitive

    My outside lights are programmed to turn off/on with the sunset/sunrise. I no longer have to reprogram them every few weeks

    Upstairs is heated during the day, room is only heated at night, and basement is manual on with an auto-off at midnight

    My water heater is only on half the day now, and I find hot water is still available if needed even when it's off

    A single tap and everything switches to vacation mode. Ask Siri to remind me to turn it back on when I get to X or at X time

    Daylight savings time is adjusted automatically on all thermostats. Outside temps are also pulled from the web

    Diminishing returns for the second winter:
