Product details

Description

This 50WCE018 is a nominal 1.5-ton vertical WSHP designed to deliver heating and cooling by exchanging heat with a building water loop or geothermal source. In occupant-facing terms, WSHPs are a proven way to give each space its own comfort control while the central loop stabilizes temperatures across the building. The refrigerant circuit uses R-454B as part of the current platform generation.

The “M” airflow configuration indicates a left-return, top-discharge vertical arrangement, paired with side filter access and front-left water connections. Beyond geometry, the value in this SKU is the option set: coated air coil selection, cupronickel coaxial water heat exchanger selection, compressor blanket plus closed-cell foam insulation, and an A2L leak detection package. That combination targets corrosion resistance, quieter operation, and additional A2L safety coverage.

Published AHRI/ANSI 13256-1 rating tables list the ECM category for this size at 18,200 BTU/h cooling and 21,800 BTU/h heating at water-loop rated conditions. Verify loop temperature range, airflow/static pressure, and filtration strategy for your application to ensure the selected size behaves the way you expect across seasons.

Key Features

  • Vertical left-return, top-discharge configuration: supports projects where return duct routing is on the left side of the cabinet.

  • Constant torque ECM blower option: ECM motor platform designed to perform predictably as static pressure changes.

  • R-454B refrigerant circuit with key service provisions: TXV-based metering approach and integral pressure ports.

  • Stainless drain pan + overflow sensor: corrosion resistance plus protective shutdown response to overflow conditions.

  • Coated air coil option (selected): added protection to help reduce air-side corrosion exposure.

  • Cupronickel coaxial heat exchanger (selected): corrosion-resistance option for more demanding water quality.

  • Sound/IAQ + A2L leak detection (selected): compressor blanket and closed-cell foam, plus leak detection coverage.
