These outputs are measured at the stated air and water temperatures. They are seasonal comparison figures, not winter pond capacities. On a small screen, scroll the table sideways to see every column.
| Model | Output A27/W27 | Output A15/W26 | Required flow |
|---|---|---|---|
| AquaForte Heat Pump Aqua Mini 3.5kW | 3.5 kW | 2.4 kW | 1–2 m³/hour |
| AquaForte Heat Pump Aqua Mini 5.6kW | 5.6 kW | 3.5 kW | 2–2.5 m³/hour |
| AquaForte Heat Pump Aqua Mini 7.7kW | 7.7 kW | 4.8 kW | 2.5–3.5 m³/hour |
Temperature and seasonal suitability
The family manual specifies an outdoor operating range of 10–43°C. This makes operating season an important selection check: do not choose an AquaMini as a substitute for a heat pump intended to continue through freezing winter conditions.
Compare the complete installation
At air 15°C and water 26°C, published heating outputs are 2.4kW, 3.5kW and 4.8kW respectively. Those figures help show why the larger warm-condition model rating should not be used as a constant output. Check the required flow and 32/38mm connections against your planned circuit.
Plan the water circuit using the flow required by the heater after allowing for the installed filter, pipes and fittings. Arrange appropriate isolation and service access, and check the electrical supply with a qualified installer. Outdoor clearance and a clear route for condensate are part of the installation, not optional extras.
Covering and insulating the water reduces heat loss. If a heater is shut down during freezing weather, follow its draining and winterisation instructions; switching off power does not remove trapped water. Our pond heating guide explains the main planning considerations.
