Understanding the energy graphs in the Qvantum app
The Qvantum app gives you detailed insight into your heat pump's performance. Here's how to interpret what you see.
Where to find the graphs
Open the app and tap Statistics or the graph icon on the home screen. You can switch between daily, weekly, and monthly views.
What the graphs show
Energy consumption (kWh)
This shows how much electricity your heat pump has used, split by:
- Compressor — the efficient heat pump cycle
- Electric backup element — the supplementary heater (higher cost per kWh of heat)
- Fans and pumps — minor auxiliary consumption
Ideally, the compressor should account for the majority of your consumption. A large share of backup element usage indicates the system is working harder than expected.
COP (Coefficient of Performance)
COP shows how efficiently the heat pump is running. A COP of 3.0 means you get 3 kWh of heat for every 1 kWh of electricity consumed. Higher is better. Typical values:
- Above 3.5 — excellent
- 2.5–3.5 — normal range
- Below 2.0 — investigate, something may be wrong
Heat production (kWh)
This shows total heat delivered to your home and hot water tank. Comparing heat production to electricity consumption gives you the effective COP.
Tips for using the graphs
- Compare consumption to outdoor temperature — higher consumption in cold weather is expected
- If consumption spikes without a temperature drop, check for alarms or a blocked filter
- Use the monthly view to track trends over time and spot seasonal patterns
