6.3 Optimal Settings for Temperature Control

The outlet hot water temperature depends on the relationship between the gas flow (temperature knob) and water flow (water flow knob). A higher water flow distributes heat better, allowing the unit to reach a wider temperature range.

• የምቾት ሙቀት; A comfortable water temperature is typically between 40°C and 55°C (104°F - 131°F), depending on personal preference.
• የክረምት ሁነታ: For colder incoming water, set the water flow to minimum and temperature to maximum. This restricts water passage, allowing it to absorb more heat from the flame.
• የበጋ ሁነታ፡ For warmer incoming water, set the water flow to maximum and temperature to minimum. This allows water to pass at maximum capacity, as the ambient temperature is sufficient for a comfortable range.
