Entering meter readings today and got the summarised gas savings since installing Evohome in December:-
Winter (Dec - Mar) 5991 units vs 6343 last year (66.5 units/ day vs 70.5 last year). Slight improvement but bad time to compare as was "tuning" Evohome and cleaning system, etc quite a lot with higher than normal use.
Spring (Apr - Jun) 3972 units vs 5077 last year (43 units/ day vs 55 last year). Around 20% down... more in line with expectations.
Summer remains unchanged at around 1400 units. I used to put heating off all day and just run water for a coupe of hours so didn't expect much difference. I think there is scope to improve Evohome savings during summer but the scheduling is a bit cumbersome for season changes- need to look at more IFTTT macros or other intelligence to sense occupancy/ water use more!
This gives tangible actual energy saving for spring 2015 of around £50. Extrapolating this looks to give savings of £100 - £150 a year (Total gas/ elec bill is only £125/ month so not high use).
Comfort wise, I was working from home for a significant amount of the period and had study only heated (and more comfortable) vs having heating completely off for much of the day.
