Talk:Solar Water Heater - Capacity 100L
Development and documentation - Technical solutions -- Inddigital (talk) 19:31, 23 January 2023 (CET)
- Parallel Tubes: preferable system
- Zigzag tubes: Proven system in commercial equipment but requires experience and additional equipment for bending
- Parallel Plates: Requires the fluid to develop enough pressure to deform the metal plates
- Copper: more expensive
- PVC: less heat transfer at the beginning, but a good working regime is reached in a short time
- Steel and galvanized iron in contact with water: more expensive than PVC piping
- A single circuit (mixed flow heat exchanger): Preferable, the utilization network can work by gravity
- Two circuits (coil heat exchanger): Requires pressurizing the network

The perforations are missing in the insulating walls for the pipes to pass through, although it is not a critical detail, this can be quickly deduced during manufacturing
- Copied, it will be added in the next version of the plans

Part number 4.00 -- Xtech2020_review (talk) 23:52, 12 January 2023 (CEST)
It is recommended to evaluate if it is necessary to place flexible sections in the pipes, to withstand thermal expansion
- The estimated elongation for these tubes sizes is really low, it can be supported by leaving clearances in the perforations.

Part number 1.05 -- Xtech2020_review (talk) 23:54, 12 January 2023 (CEST)
In this sheet, the capture of solar energy can be optimized, simply with a coating of black paint, this detail is not observed in the project
- Copied, it will be added in the next version of the plans

Part number 3.05 -- Xtech2020_review (talk) 23:56, 12 January 2023 (CEST)
Here you can include a relief valve so that it only works to release the excess pressure and this access is not all the time losing heat from the tank
- This would make the project more expensive, in addition, it is not expected that so much heat will escape through that hole, in any case a U curve can be added for a future version of the plans

Please include a commercial reference

- You must place a hose or tube at the water outlet of this valve, to guarantee that the cold water enters through the bottom of the tank

Indicate the means of joining these plates to the lid sheet, ...riveting?
- Correct, this union is riveted, I will include it in a future delivery of the plans

Part number 1.00 -- Xtech2020_review (talk) 00:02, 13 January 2023 (CEST)
The configuration of the tubes in the manifold makes it difficult for them to be threaded, it is recommended to use accessories to glue
- Copied, it will be added in the next version of the plans

Part number 1.00 -- Xtech2020_review (talk) 00:02, 13 January 2023 (CEST)
It is recommended to include a rubber or silicone in the contact of the glass with the metal, this can only be indicated
- Copied, it will be added in the next version of the plans
