Multi-Source Water Heater Design for Reduced Energy Cost and Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water heaters are inefficient in reducing energy costs for both end users and suppliers, as they primarily rely on a single power source, leading to high energy consumption and costs.
Innovation Solution
A water heater system with multiple heating elements, including a first element in the inlet pipe powered by a utility source, a second element in the outlet pipe powered by renewable energy, and an optional third element powered by backup sources like batteries or wind turbines, allowing for efficient temperature maintenance and energy savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a single power source is used to heat water, then the system is simple to operate, but energy costs are high
Solution Approach 1:
The heating system is divided into multiple independent heating elements (first heating element in inlet pipe, second heating element in outlet pipe, third heating element in bypass pipe) that can operate independently or in combination, allowing selective use of different power sources to reduce energy costs while maintaining system functionality
Solution Approach 2:
The water heater system is designed to accept multiple power sources (utility power, renewable energy sources, backup power sources) and can switch between them automatically, making the system universally adaptable to different energy availability conditions while maintaining consistent water heating performance
2Loss of energy
If multiple heating elements are used, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The heating function is segmented across three separate heating elements positioned at different locations (inlet pipe, outlet pipe, bypass pipe), allowing each element to address specific heating needs and reduce energy losses in different parts of the system
Solution Approach 2:
The bypass pipe with the third heating element acts as an intermediary pathway that allows cold water to be heated before entering the main tank, reducing the energy burden on the primary heating elements and improving overall energy efficiency
3Temperature
If water is heated to high temperature, then user comfort is improved, but heat loss increases
Solution Approach 1:
The first heating element pre-heats incoming cold water before it enters the main heating zone, reducing the temperature differential and subsequent heat losses from the storage tank while still achieving the desired final water temperature

AI summary
A water heater and a method for heating water using various power sources and enhancing energy savings are disclosed. The water heater includes a first heating element within an inlet pipe. The first heating element draws energy from a first power source to heat water to a first temperature. The water heater further includes a second heating element within an outlet pipe. The second heating element draws power from a second power source to heat water from the first temperature to a second temperature. Optionally, when the second power source is unavailable or insufficient, then the second heating element draws power from a third power source to heat water from the first temperature to the second temperature.
