Case Study

Parallel Air-to-Water Heat Pump Technology Implementation

📍 EcoVillage North Carolina 🗓️ Installed in 2025

Project Summary

A proven energy solution with real results — the parallel air-to-water heat pump system achieved over $24,000 in documented annual savings, fully eliminated propane heating costs, and ensured zero system downtime across multiple commercial buildings.

The Challenge

The EcoVillage development faced extreme winter temperatures (down to 0°F), complex multi-zone layouts, and installation limitations with traditional systems. A smarter, more adaptive, and energy-efficient solution was essential.

The Solution

Parallel Heat Pump Configuration with 1,500-gallon thermal storage:

  • 4 units running simultaneously in parallel.
  • Smart modulation for dynamic load matching.
  • Built-in redundancy (no single point of failure)
  • Solar-ready and compatible with advanced building automation.

Key Results

  • $18,000/year in propane cost elimination (100% offset).
  • $6,000/year in additional utility savings.
  • 0% system downtime since installation.
  • Over 30 tons of installed capacity across multiple sites.

Recommended Use Cases

Multifamily residential developments
Commercial buildings with simultaneous heating/cooling demands
Municipal and district-scale energy projects
