"efficient heating, cooling... HotTwist heat exchanger compresses to higher temperature... coupled to standard ground source heat pump, it collects heat from water bodies instead of ground... 2x more than ground, ~3400x more than air... glycol, aiding when cold, circulates through looped tubing, warmed glycol compressed raising its temperature... also harness energy from frozen water utilizing ice fusion latent heat... 350% to 400% more heat than electricity input, comparable to most efficient air source heat pumps"
