Wall-Mounted Hot Water Tank Layout for Easier Heat Pump Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combined devices for heating sanitary water and room water face difficulties in installation and connection due to large size and mass, making them hard to handle and install, especially requiring them to be placed on the ground rather than suspended, which complicates the installation process and limits flexibility in construction settings.
Innovation Solution
A modular combined device design that allows suspension above the ground, with each module weighing less than 55 kg, featuring a connection plate for standardized connections and a heat exchanger arrangement outside the storage tank to reduce overall dimensions and mass, facilitating easier installation and connection of heating and sanitary water systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the combined device uses a large storage tank (190 L) with an internal coil heat exchanger, then the domestic water heating function is achieved, but the device mass exceeds 55 kg and height reaches 1.84 m, making it difficult to handle and requiring ground placement
Solution Approach 1:
The patent extracts the heat exchanger from the storage tank interior and relocates it to the tank exterior. This removes the space-consuming coil structure from inside the 190 L tank, maintaining full storage capacity while significantly reducing the overall device dimensions and mass, enabling wall-mounted installation.
Solution Approach 2:
The patent transitions from a horizontal/ground-based configuration to a vertical/wall-mounted configuration. By positioning the heat exchanger externally and optimizing the vertical arrangement of components, the device achieves compact height suitable for wall mounting while preserving the required storage volume.

3Adaptability or versatility
If the combined device is designed as a single integrated unit, then all functions are combined, but the device mass exceeds 55 kg making handling by a single installer prohibited
Solution Approach 1:
The patent segments the combined device into distinct functional modules: a storage tank module and a heat exchanger module. Each module can be handled separately (under 55 kg), yet they are designed to be installed as an integrated system, maintaining all required functions while improving installability.
4Device complexity
If the heat exchanger is placed inside the storage tank, then compact arrangement is achieved, but the interior volume available for water storage is reduced
Solution Approach 1:
The patent extracts the heat exchanger from the storage tank interior and relocates it to the tank exterior. This removes the space-consuming coil structure from inside the 190 L tank, maintaining full storage capacity while significantly reducing the overall device dimensions and mass, enabling wall-mounted installation.
5Device complexity
If the connectors are positioned at specific locations on the casing, then the device structure is simplified, but the installation becomes complicated as connection positions cannot be predetermined
Solution Approach 1:
The patent introduces a standardized connection plate that serves as a universal interface for all fluid connections. This single component integrates multiple connection points in fixed, predetermined positions, allowing plumbing work to be completed independently of the combined device installation and ensuring compatibility across different device models.
