Bosch Greensource SM Series Geothermal Water Source Heat Pump Upgraded For Higher Reliability and Comfort

The Geothermal Water Source Heat Pump has been upgraded for improved installation, serviceability and reliability. Features include an all-aluminum evaporator coil resists formicary corrosion, capacities from 2 to 5 tons, with Energy Efficiency Ratings of up to 37.0 (GWHP-PL), and Coefficient of Performance Ratings of up to 5.8 (GWHP-PL). Units are available in vertical, horizontal and counterflow configurations.

Londonderry, New Hampshire - Bosch Thermotechnology Corp. announced today that upgrades to its SM Series, two-stage geothermal water source heat pump are now available.

Bosch redesigned its SM vertical and counterflow cabinets with an increased focus on serviceability and reliability, with front water connections and an all-aluminum air coil to resist formicary corrosion. Bosch also redesigned the internal layout for easier access through the front panel to components most often requiring service or adjustment.

The newest models of the SM Series come in cooling capacities ranging from 2-to-5 ton packaged vertical, counterflow, and horizontal units, allowing for a variety of configurations in residential applications. Plus, each Greensource unit is recognized as ENERGY STAR Most Efficient, with best-in-class performance, Energy Efficiency Ratings (EER) of up to 37.0 (part load) and 28.0 EER (full load), and Coefficient of Performance (COP) of up to 5.8 (part-load) and 5.5 (full-load) GWHP. This equates with lower operating costs to save homeowners money.

The fiber-free, closed-cell insulation provides thermal and acoustic insulation while also improving air quality. The redesigned model means operation is whisper-quiet, with sound levels as low as 52 dBA (comparable to the clicking noises produced by typing on an average computer keyboard).

Along with the Bosch-designed acoustic insulation, the SM Series utilizes a variable speed standard ECM blower motor. This feature seamlessly adjusts to maintain constant airflow and comfort. Plus, the innovative filter rack is easy to access and houses a two-inch MERV-8 filter to further improve indoor air quality.

Coupled with more than 10 safety features and backed with a ten-year limited warranty on parts and labor, Greensource provides a total solution in energy-efficient home comfort.

Geothermal heat pumps are designed and built in Boschs ISO 9001 and ISO 14001 certified facilities in Fort Lauderdale, Florida. They serve as a platform for renewable energy products in a residential comfort control system. CDi series model SM heat pump was awarded ENERGY STAR® 2016 Most Efficient product recognition. The new CDi Series meets ENERGY STAR Tier 3 requirements, making it eligible for up to a 30 percent federal tax credit*.
