Why this unit
The 500W11 is a water-to-water heat pump: instead of blowing warm air, it makes hot (or chilled) water for radiant floors, pool and spa heating, snow-melt loops, and process water. Capacities run from 2 to 15 tons, in heating-only or heating-and-cooling versions.
Single and dual hydronic variants, R-454B low-GWP refrigerant, and HydroZone panels to run multiple water circuits from one unit.
Best for: Radiant floor homes, pools and spas, snow-melt driveways.
- 2 to 15 ton capacities, single or dual hydronic
- Radiant floors, pool and spa, snow melt, aquaculture
