Central Domestic Hot Water, Reimagined for Modern Buildings
Factory-assembled COâ‚‚ heat pump systems designed to simplify installation, improve system performance, and support the transition to electrified central hot water
WaterDrop Systems delivers complete, engineered hot water plants designed to reduce installation risk, simplify coordination, and improve long-term performance. Unlike traditional site-built systems assembled from multiple vendors, WaterDrop integrates heat pumps, storage, controls, and monitoring into one coordinated platform.

Both configurations support electrification, predictable performance,
and reduced installation risk.
Why Project Teams Choose WaterDrop
Factory-Built Systems
Pre-engineered and assembled systems reduce field coordination, shorten installation time, and improve consistency.
Integrated Plant Intelligence
Controls, monitoring, and equipment are designed together - not assembled in the field.
Designed for Lifecycle Value
Optimized for long-term performance, maintainability, and operational cost - not just first cost.
WaterDrop Complete Skids
Packaged central domestic hot water plants for simplified delivery and installation
WaterDrop Complete Skids are fully integrated domestic hot water plants designed around real building demand. Each system is factory-assembled and includes heat pumps, storage, controls and re-circulation components in one coordinated page.
This approach reduces on-site complexity and ensures the system performs as designed. It also provides a clear path from engineering to installation, minimizing risk, and improving project timelines.

A Smarter Way to Deliver Hot Water
Generate Hot Water
WaterDrop Systems use CO2 heat pumps to generate hot water.
Store and Deliver
Thermal storage tanks store energy efficiently and deliver hot water throughout the building.
Integrated Controls
Integrated controls manage staging, system response, and load shifting while monitoring tools provide real-time insight into performance.
This coordinated system approach supports electrification while improving reliability and operational predictability.
