This was really good. A Zombie-bitten father trying to save his daughter before he turns. Such a well done short film.
Direct Energy: Geothermal..... Geothermal pump systems reach fairly high Coefficient of performance (CoP), 3 to 6, on the coldest of winter nights, compared to 1.75-2.5 for air-source heat pumps on cool days. Ground source heat pumps (GSHPs) are among the most energy efficient technologies for providing HVAC and water heating. Setup costs are higher than for conventional systems, but the difference is usually returned in energy savings in 3 to 10 years, and even shorter
