DALLAS - ClimateMaster’s new Vertical Stack water-source heat pump is part of the Tranquility Series of heat pumps, available in sizes from 3/4 ton through 3 tons. The chassis is backwards compatible with ClimateMaster and California Heat Pump (CHP) R-22 Vertical Stack cabinets.

Efficiencies with the R-410A units are noticeably higher than the R-22 products, and the new units are designed for ground loop (geothermal) or water loop (boiler-tower) applications.
