Calculate Water Heater Efficiency





Formula

The formula to calculate the Water Heater Efficiency is:

\[ Ewh = \frac{m \cdot C \cdot \Delta T}{Q} \times 100 \]

What is Water Heater Efficiency?

Water Heater Efficiency refers to the ratio of useful energy output to the total energy input. It indicates how effectively a water heater converts energy into heating the water. A higher efficiency means less energy is wasted, resulting in lower energy costs and reduced environmental impact.

Example Calculation

Let's assume the following values:

Using the formula:

\[ Ewh = \frac{50 \cdot 4.186 \cdot 30}{700000} \times 100 \approx \frac{6279}{700000} \times 100 \approx 0.897 \% \]

The Water Heater Efficiency is approximately 0.897%.
