WaterDrop systems were developed by Small Planet Supply and ECO2 Systems to utilize the high-performance capability of SANCO2 heat pump water heaters for commercial and multi-family applications. WaterDrop systems are manufactured in Tumwater, Washington and Richmond, British Columbia. The systems are the culmination of the learning from hundreds of site-built systems across the United States and Canada.

The concept of creating a plug and play hot water plant system was appealing to businesses, utilities, and local jurisdictions because it would offer many benefits to multi-family and commercial building developers, including:

  • Decreased need for specialized installers for DHW plant installation

  • Reduction in onsite installation time

  • Increased building design flexibility

  • Performance proven confidence in the DHW system


The goal of WaterDrop systems is to make DHW plants easy to specify and install. Partnerships with public utilities and the Province of British Columbia have been instrumental in the successful development of our WaterDrop systems. Our experience and expertise make selecting WaterDrop systems for your project an easy choice.
