4-Step Guide to Designing Geothermal Systems
The first part to understanding any aspect of the geothermal industry, whether it be marketing, sales, design or installation is to understand how the technology works and it is designed. By understanding the design process, even if you are never going to do design yourself, you will better understand how the technology is sold, will be confident when speaking to customers, will know what information needs to be collected on a site visit, and which leads have greater potential then others. If you plan on working on the installation side, understanding design will give you the knowledge to understand the different parts of an installation and what those may cost.
