This is the steam generator design I used to have my custom boiler manufactured. You can take this blueprint to a local stainless steel fabricator and have it made.
The file is a PDF with all dimensions and measurements on it.
**WARNING** This blueprint is for educational purposes. All construction and operation is done at your own risk. All boiler systems must be checked by the local authority prior to use.
Below is a list of items you need to complete the build. You also want a safety water shutoff switch and a over heat protection swith.
