Frequently asked questions
- How is the saving calculated?
- Therilly compares your actual hourly electricity price against a reference curve for "the same heating demand without smart control". The difference over a month is your real saving — shown in the in-app monthly report.
- Why 15–30 % and not more?
- Spot prices vary 5–8× across a day. Shifting load from the most expensive to the cheapest hours — without losing comfort — has a mathematical ceiling around 30 %. On extreme days (cold snaps, no wind) individual days can reach 40–50 %.
- Does the price zone affect savings?
- Yes, a lot. SE4 (Skåne) has the highest volatility and therefore the biggest savings potential — typically 22–32 %. SE3 is 18–28 %. SE1 and SE2 have lower volatility, typically 5–15 %.
- What does it take to maximise savings?
- Three things: an hourly spot contract with low markup, a heat pump built after 2010, and a power meter providing real-time data. With all three in place, savings sit at the top of the range.
