Design

It is important to ensure your geothermal system is properly designed prior to installation. Some things to look for from your contractor are a heat loss/gain calculation on your home to assess the requirements for your household. From this an appropriately sized system can be designed. Further variables such as available land space, local soil types, distance to groundwater, all need to be factored in to ensuring your home will have a properly sized system. There is nothing wrong with asking your engineer or contractor to provide you with these details. If anything, these records help in future troubleshooting should it be required.
