| Short Description |
In Chapters 173-160-111 (32) and 173-160-410 (4) WAC (Washington Administrative Code) it defines ground source heat pump boring as "a vertical boring constructed for the purpose of installing a closed loop heat exchange system for a ground source heat pump." Currently, the most common use of a ground source heat pump boring is for large commercial or government building heating and cooling systems. The most common loop material is high-density polyethylene pipe. The average boring depth is about 300-feet. And the most common installation method is with mud-rotary drilling. Hundreds of these wells are constructed in Washington every year. | |
