Project development

Based on the DIN 2221 standard, among others, OHO has established a series of stages in which the satisfactory completion of this project was carried out 1 Feasibility study Manufacturing as OSAT technology is possible? Materials, components Required materials and components can be sourced or replaced locally? ✓ Yes, most of these Most of the materials can be found in local environments (hardware stores), in the case of fiberglass wool, it can be obtained in internet purchases and in extreme cases, it can be substituted by others such as Bamboo cloth, Basalt cloth , among others Manufacturing processes Required manufacturing processes can be povided locally? ✓ Yes All manufacturing processes can be located locally, without the need for specialized workshops Specific training Is specific training for manufacturing necessary and can be provided? ✗ No No specific training is needed to build this device Sustainability Do all materials and processes meet the sustainability criteria? ✓ Yes The product and its production process can be considered as sustainable 2 Market analisis and requirements Functional and quantitative requirements Functional and quantitative requirements Market analysis Analysis of the current products on the market: Solar Water Heater, 100% Solar / 100 Liters * Price [USD]: 415 * Source: mercadolibre * Country: Colombia * Machine condition: New * Heated volume [L]: 100 * Temperature [°C]: 90 * Mixed flows: Yes * Pressurized tank: No 40 Gallon Solar Water Heater * Price [USD]: 194 * Source: amazon * Country: USA * Machine condition: New * Heated volume [L]: 151 * Temperature [°C]: 60 * Height difference [m]: 1 * Mixed flows: Yes * Pressurized tank: No 220 Electric Solar Water Heater * Price [USD]: 171 * Source: mercadolibre * Country: Argentina * Machine condition: New * Heated volume [L]: 200 * Temperature [°C]: 100 * Height difference [m]: 1.68 * Mixed flows: Yes * Pressurized tank: No 200L Atmospheric Solar Water Heater - Aluminum structure * Price [USD]: 118 * Source: Gruntech * Country: Argentina * Machine condition: New * Heated volume [L]: 200 * Height difference [m]: 1.62 * Mixed flows: Yes * Pressurized tank: No SEA Solar Passive Water Heater With Un-pressurized Tank 40Gallon/50G/80G * Price [USD]: 1119 * Source: ebay * Country: USA * Machine condition: New * Heated volume [L]: 200 * Temperature [°C]: 95 * Mixed flows: Yes * Pressurized tank: No Requirements definition Definition of the main technical data: Heated volume [L]: 150 Temperature [°C]: 70 Height difference [m]: 1 Optimal functions and features Definition of necessary/optional functions and features: Mixed flows: Preferably mixed flows, a coil requires pressurizing the network Pressurized tank: No 3 Search & analisis DIY technologies The best technical solutions for all parts and components OHO Search engine Customization of the OHO search engine A search for similar or related equipment was carried out in our repository, obtaining some equipment that can be used as a reference Manual search Manual search in Google, Youtube, special websites etc. * Title: DIY Solar Water Heater!

Manufacturing, tests and improvements To date, this project is on hold for manufacturing. 6. Certification DIN Spec 3105 Formal audit Verification of the completeness of the documents: * Parts list * Drawings of all parts and assemblies * Assembly instructions * Optional documents, technical notes * These formal aspects have been verified, the project meets them satisfactorily Assignment of reviewers Search and assignment of peer-reviewers with sufficient expertise: Xtech2020_review Thehunter Peer-reviews Realization of the peer reviews, technical clarification, improvements: In the Parts list section, necessary comments and discussions have been made by the assigned reviewers and the developer Certificate Issue of the certificate: The project was reviewed by two reviewers from the OHO team. The review consisted of the following components: * Completeness check: Checks if all required documents have been submitted. * Review of the submitted documents: Checks if the information in the submitted documents is complete and correct. - Bill of materials - Are all parts and assemblies covered? - Are all quantities correct? - Are all required material specifications available? - Are all specifications for purchased parts and standard parts complete? * Technical drawings - Are all the required views available? - Are all required dimensional data available? * Suggestions for improvement Detail abot the review process: https://en.oho.wiki/wiki/Instructions_for_Reviewers Permanent Link: https://en.oho.wiki/index.php?title=Solar_Water_Heater_-_Capacity_100L&oldid=45789
