Usually, the temperature of the shallow ground is warmer than that of the air above, and in contrast, cooler than the air above during summer time. Geothermal pumps use this force to their advantage and thus are considered stable and more effective heating devices. They can also operate as air conditions or heaters.Geothermal pumps are often mentioned as more efficient “green” energy, the type that could alleviate energy cost and help stop global warming. Manufacturers of these devices include Addison, ClimateMaster, Econar, McQuay and Rheem Classical/Prestige. Some of the top systems available online include the Addison VWY VGY Water Source Self-Contained (8-30 tons), the McQuay Enfinity Horizontal & Vertical Water Source Heat Pumps and the Rheem Prestige Series RPRL-JEZ Two-Stage Heat Pump.
The main disadvantage of geothermal pumps is that they take money to set up, more so than buying averagely expensive equipment of air source electric heat pumps, and more expensive equipment in dual-fuel pumps. If you choose a system that doesn’t take electricity, and only uses geothermal heat, then you could eventually save money-but you won’t recuperate your costs until years later. Nevertheless, system life is well over a century if maintained properly.
