Water Source Heat Pumps (WSHP)

Islandaire Water Source Heat Pumps (WSHP)Islandaire designs and manufactures water source heat pumps (WSHP). These models can be used for direct replacement of McQuay, Singer and Climate Master units or in new construction projects. A downloadable Water Source Product Catalog can be found here.

EZ Series LM

This appliance is intended for new construction or replacement of McQuay and Singer LM water source heat pumps. Islandaire “The Perfect Fit” units are designed to exactly replace the original, existing chassis! No field modification kits or builder renovations are required. Islandaire units are designed for optimal efficiency and reliability. This unit has the ability to have the piping and the controls “reversed” in the field. If you order the wrong side for piping and controls, no problem. Just reverse them in the field saving time and money. Please confirm that the electrical rating of this appliance matches the electrical supply available before beginning installation.
