Colmac Waterheat

What Colmac Waterheat does

Colmac WaterHeat, Inc. is a privately held, third-generation family-owned manufacturer of commercial heat pump water heaters, headquartered in Colville, Washington. Founded in 1957 as part of Colmac Industries and spun out as an independent entity in 2024, the company designs and builds air-source and water-source heat pump units in the 4–30 horsepower range (CxA, CxV, CxW, HPA, HPW series) capable of producing domestic hot water at 140°F+ in a single pass, using stratified storage to extract significantly more usable BTU capacity per tank. The product portfolio is differentiated by industry firsts — the R-22 to R-134a transition, double wall-vented heat exchangers for potable water, 140°F+ single-pass output, and low-GWP R513A refrigerant options — and complemented by storage tanks, modular water systems, single-point wiring, the CxS cloud-based supervision platform, and NSF/ANSI 61 certification for potable water safety across 49 U.S. states.

The company goes to market primarily through a worldwide factory representative network of 28+ firms in North America plus coverage across South America, Europe, Asia, Africa, Australia, and Antarctica, with applications engineers providing technical sales support, training for engineers and architects, and project-specific equipment customization. Revenue is generated through hardware sales of heat pump units and ancillary tank/piping systems, supplemented by professional services for startup, training, and maintenance. Pricing is quote-based and not publicly disclosed.

Customer end markets are concentrated in commercial buildings and multifamily residential, with named installations including Silver Oak Apartments, UC Davis student housing, and Batik Apartments. Distribution relies on regional reps promoting long-term relationships with dealers, consultants, and specifying engineers, with the company selling primarily to enterprise buyers and project-driven specification channels rather than mass-market retail.

Core offering

Colmac WaterHeat manufactures and sells commercial heat pump water heaters (4 to 30 horsepower) in air source (CxA, CxV, HPA) and water source (CxW, HPW) configurations for domestic hot water production in commercial and multifamily buildings. The company also offers complementary water tanks, modular water systems, single point wiring, and the CxS cloud-based supervision platform, along with professional services such as startup support, training, and maintenance.

Product overview

Colmac WaterHeat offers a comprehensive portfolio of commercial heat pump water heating products organized into three main categories: (1) Hot Water Heat Pumps including the CxA, CxV, CxW, HPA, and HPW series heat pump units ranging from 4 to 30 horsepower in both air source and water source configurations; (2) Add-on modules including the CxS Supervision System for cloud-based monitoring, Single Point Wiring for simplified electrical installation, and Energy Analysis Package for performance evaluation; (3) Water Tanks and Accessories including Electric Heater Tanks, Storage Tanks, Headers, Hose Kits, Mixing Stations, and a complete Modular Water System. The product architecture follows a modular approach where heat pump units (CxA/CxV/CxW/HPA/HPW) form the core heating technology, supported by the CxS cloud monitoring platform and compatible with the modular tank and piping systems for complete hot water system installations.
