Research-based guides
The launch guides summarize selected public information and provide original worked examples. They are not independent laboratory tests or claims that the publisher has used the products mentioned.
Illustrative numbers
Example purchase prices, power levels and electricity rates are hypothetical unless explicitly attributed to a dated source or measurement. Savings depend on actual conditions. No calculator guarantees a lower bill.

Independence

Practical limits
The calculators estimate electricity costs under the stated assumptions. They do not assess installation safety, diagnose faults or establish a product’s suitability for a particular building. Use the selected model’s instructions and seek appropriate help for the installation.
