Frequently Asked Questions
Common questions about Hot Water Mixing Calculator, formulas, and expected usage.
How is hot-water mixing calculated?
The hot-water fraction is (target minus cold) divided by (hot minus cold), then multiplied by total flow.
Why must target temperature be between hot and cold inputs?
A mixed temperature outside the source range is physically impossible without heating or cooling beyond the two source streams.
What is this calculator useful for?
It is useful for tempering-valve setup, domestic hot water balancing, and estimating required hot-water capacity.
Does this include pipe heat loss?
No. This is an ideal mixing calculation at the blending point and does not include downstream heat loss.
