Having a Smart Heating system is great. It controls your energy in better ways, offers greater control, and lets you adjust things like temperature and schedule much more easily. However the biggest question is - does it save me energy & money? Here, I explore a little on how you can see where you're saving.
I've had the Tado system in a few months now, so I felt it was a good point to look at whether it's actually saving me energy and money. This -as it turns out- isn't a particularly easy thing to do. After all, weather and temperature conditions change from one months to the next, and it's hard to figure out how much I might have been spending without Tado.
Tado though have their own energy saving report built into their app, so this at least provides some insight into how things are going.
At the end of each month, a new report is generated for that month. So for example right now the most recent report available is for the month of February, where Tado estimates I saved 16.9%. Tado further expands on this by telling you how many hours of 'away mode' occurred during the month (114 hours for me), how many hours of weather adaptation (67 hours), how many occurrences of open windows detection (none for me as I haven't turned this feature on yet), how many hours of smart schedule per day (8.7), and savings through manual control (turning the temperature down yourself in the app - 1.1% for me).
You can of course go back and see previous months to compare how well you're doing. What does this mean in monetary terms? Well, the app doesn't tell you this. Indeed it would probably need to know a lot more information about your energy costs, tarrif, billing etc to be able to give that kind of information!
Is the data accurate? Well, even Tado flag this as an estimate only, and indeed there are a few assumptions that are being made to generate this data. Tado can't know with 100% accuracy how you'd have been heating your home without their system in place, so take it with a pinch of salt.
Nevertheless, having this information available does at least provide some insight into how and where you're saving with the system. If the figure seems to be too low, then it can help flag up that you maybe need to make a few adjustments somewhere.
We saw a big difference between December (savings of around 11%) and January & February (savings in the 17% region). This I put down to our installation of our first few Tado Smart Theromostatic Radiator Controllers. I'm hopeful that when we install more around the house, our energy savings will rise further.
I'll of course report back in future on how we get on with our energy savings. I haven't decided yet whether to make it a monthly report - but it's certainly something I plan to keep track of.
