i'm too close to san francisco bay.
Why is that bad? I thought ground-source HVAC systems worked better if the ground was saturated with water. Better thermal conductivity than dry soil.
aside from the corrosive nature of the salt and other minerals, there is an unbelievable maze of permits from various layers of government since there's a protected marshland as well as habitat restoration within a few miles. i think it's safe to say that Sun Quentin could not be built under current rules.
My problem finding someone to install a ground-source system was that everyone for miles is on city water. You have to be able to drill a hole in the ground and the folks familiar with well-drilling equipment are three hours away.
i could drill in the warehouse, i suppose, and truck the slurry out by night.
