Geothermal Heating Systems
Geothermal Heating Systems are re-emerging as a feasible method for HVAC in homes and LEED businesses. Therefore, the City has modified our building permit application to have a separate box to check when geothermal HVAC systems are installed in homes. The applicant will need to check this box and provide the following information;
- Description of the type of system being installed; closed-loop, open-loop, water source if applicable, water discharge location, if applicable, and pipe materials to be used.
- The plot plan (residential permits) or staking plan (commercial and site plan permits) shall reference the locations of the well(s), piping systems and any other pertinent site information.
- The current code requires a permit with fee for all water wells drilled within the City. The current 2009 and 2010 fee is $20 per well drilled.
This information shall be submitted to the City of Dublin with the rest for the required building permit submission. Engineering and Building will review the submitted information for compliance with Dublin City Code Section 52.03.
