Verify the inputs
Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.
Wells & water/ CALCULATOR
Hot and cold water mixing
Estimate hot and cold volumes needed to reach a target mixed-water temperature.
FROM ESTIMATE TO ACTION
Use the result, not just the number.
Keep the calculation traceable
Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.
Confirm the decision
Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.
Inputs to verify
- Required mixed-water volume (L)
- Total useful mixed volume at the target temperature.
- Hot-water temperature (°C)
- Temperature entering the mixing point.
- Cold-water temperature (°C)
- Temperature entering the mixing point.
- Target mixed temperature (°C)
- Must be strictly between the hot and cold temperatures.
