Solution Overview
Problem
Current heating water heaters stop providing indoor heating when used for domestic hot water, leading to a drop in indoor temperature, affecting user experience.
Innovation Solution
A method for controlling a heating water heater that adjusts the flow distributor to increase the heating outlet opening degree and decrease the heat supply outlet opening degree when the heat load is below the rated load, maintaining the water temperature within a preset range while diverting hot water for both indoor heating and bath use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the opening degree of the heat supply outlet is increased to maintain indoor temperature, then indoor heating is improved, but the heat load of the heating water heater increases
Solution Approach 1:
The control unit changes the operating parameters of the heating water heater, specifically adjusting the heat load based on the opening degrees of the flow distributor. By optimizing the parameter combination of heat supply outlet opening degree, bath outlet opening degree, and heat load, the system can maintain indoor temperature while avoiding excessive heat load
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach maintains a stable indoor temperature and ensures continuous comfort by adjusting the heat load and water temperature at the bath outlet, preventing excessive fluctuations and ensuring the water temperature remains within the preset range.
Implementation Method 1
the bath flow path is configured for heat exchange with the heat supply branch

AI summary
Disclosed are a method for controlling a heating water heater, a heating water heater, and a computer-readable storage medium. The method includes: controlling the heating outlet to be closed and the heat supply outlet to be opened after receiving a bath water signal; obtaining a water temperature of a bath outlet; obtaining a duration that the water temperature at the bath outlet is within a preset water temperature range; controlling an opening degree of the heat supply outlet to decrease and an opening degree of the heating outlet to increase when the duration is greater than or equal to a first preset duration, and a heat load of the heating water heater is less than a rated load; and controlling the heat load of the heating water heater to increase, and maintaining the water temperature at the bath outlet within the preset water temperature range.
