The story is not yet over

I’m writing this while suffering from jet lag, so my body thinks it’s 6pm in the evening rather than 11pm… And that’s despite not having much sleep last night…

Oh, this is going to be SO worthwhile!

Shhh, bear with me. With this extra time I managed to screw up my contribution to the tado app billing data – with these values, the tado app can estimate how much of your heating is costing you and whether you are getting any savings or not.

For many at the moment, that would be useful information.

When we first installed the system back on 29th September 2021, our unit cost of natural gas was 2.63p per unit (a kWh). We didn’t install everything everywhere. but did our upstairs radiators, 7 smart radiator valves in total. We then expanded that until all of our heating controls were now tado versions.

Partly that was to do with cost, but I also had an existing system. Anyway, that first trial seemed to work well – we were warmer but using much less gas – win/win we thought. Let’s have some more of that.

But of course, the proof is in the pudding. A comparison of year on year is not particularly useful as every year is different – when it’s warmer, a thermostat will automatically save you money. This is one of the nicer points of the tado analysis: they will do that for you too! See the “Tado analysis in action” below:

Semi-interesting and coherent…

Thanks. Now, our jet lag is due to travelling and geo-fencing provided by tado automatically set the house up for “away mode” and we warmed the place back up remotely. All great and what you’d expect from a smart home.

For me, though, our move has given us a means of controlling our heating while prices have risen to 9.81p per unit, keeping us comfortable, and yet reducing our carbon footprint dramatically… Our usage over the past three years can be seen below – which hides the fact that Feb 2021 had inches of snow lingering on the ground for much of the period – yet the temperature was about the same in Feb 2022 and this year, as seen above, was a similar ball park. Let me say that another way – getting the whole system upgraded meant that we saved money in Feb despite the fact it was no warmer. Yet, we (and the house) were much more comfortable.

Until we can lose our gas boiler, that may be a wrap.
