GeoSource^® Vara 2 Plus^™

What do you do to make a great ECONAR GeoSource heat pump based on ColdClimate technology better? You make it variable with a two-step compressor driving R-410a refrigerant and use an energy efficient variable speed Electronically Commutated blower Motor (ECM). This could be the best GeoSource heat pump ever!

Two-step scroll compressor: Controls heating or cooling more closely to the building's load. During most of the season, first stage engages operating at peak efficiency, but during cold or hot spells, the second stage engages providing full capacity heating or cooling at the high efficiencies GeoSource heat pumps are known for. Using ColdClimate technology, the Vara 2 Plus' first stage is designed to meet more of the seasons comfort needs providing maximum savings.

R-410A refrigerant: The next generation of refrigerant with no ozone depletion potential and increased energy savings.

ECM motors: The next generation in motor technology provides increased energy efficiency in two ways. First they operate far more efficiently than traditional PSC (Permanent Split Capacitor) motors. Where they really shine is when operated at lower fan speeds. PSC motors can be set to lower speeds but their energy consumption does not drop as fast as fan output. ECM motors realize significant savings as fan output is lowered. Secondly, ECM motors maintain compressor efficiency by increasing fan speed as airflow restrictions occur. By assuring compressor-required airflow, system efficiency and low operating costs are maintained. High energy efficiency, low cost operation, environmentally friendly and comfort, all from one ECONAR GeoSource Vara 2 Plus heat pump.
