United States ThermoAmp

What United States ThermoAmp does

United States ThermoAmp Inc. is a privately held manufacturer of swimming pool heat pumps sold under the Heat Siphon brand, operating continuously from a single facility at 1223 Heat Siphon Lane, Latrobe, Pennsylvania since 1983. The company was founded by Bill Bernardi (current President and CEO), John Kopec, and Mike Tucciarone — all former members of EUS Inc.'s pool heat pump product development team — and remains under founder ownership with no institutional, private equity, or parent company investment identified. Core technology centers on air-source heat pump pool heaters built around scroll compressors, titanium tube-in-tube heat exchangers with a patented electrically isolated Iso-Cap fitting, thermostatic expansion valves, and proprietary analog (single-knob TimerStat Pro) or digital (two-button Player/Player Plus) controllers. The product line spans 2.0HP to 7.0HP residential units plus higher-capacity commercial configurations, with the latest models incorporating built-in WiFi for remote monitoring.

The company's revenue model is anchored in wholesale hardware sales of pool heat pumps through a qualified dealer network — pool builders, pool retailers, HVAC contractors, pool service professionals, and solar/geothermal heating contractors — supplemented by direct factory sales of seconds and refurbished units via a toll-free line. Pricing is not publicly disclosed; quotes are obtained through dealers or direct factory contact. Revenue streams include unit sales (Analog C-Series and Digital Z-Series across 200HP to 700HP tiers) and aftermarket service parts (compressors, capacitors, contactors, TXV assemblies, circuit boards, sensors). Marketing is anchored by HeatSiphonalysis, a proprietary pool heating cost analysis web tool that generates personalized sizing and payback reports, alongside a free dealer kit program and customer testimonial-driven content marketing.

Customers are primarily residential pool owners seeking to extend swim season and reduce heating costs versus gas/propane/electric resistance alternatives, with secondary exposure to commercial and municipal aquatic facilities (e.g., the 12-unit Cranberry Township, PA community pool installation). The company claims approximately one-fifth of all new pool heaters sold in the US now use Heat Siphon heat pump technology, supported by six granted US patents on core innovations, four registered trademarks, and an installed base serviced through 300+ nationwide service centers. Markets served include the US, Canada, and Costa Rica, with global dealer shipping referenced.

Direct peers

• Raypak: Raypak is a US manufacturer specializing in pool, spa, and commercial water heating equipment including gas, electric, and heat pump pool heaters. Headquartered in California, Raypak competes in the same pool heater category as Heat Siphon, particularly in commercial and large-residential installations where Raypak has strong presence. Comparable in product category and dealer-channel GTM.
• AquaCal: AquaCal is a Florida-based direct competitor manufacturing swimming pool and spa heat pumps under the HeatPro and AutoPilot brands. Most directly comparable to Heat Siphon in product (heat pump pool heaters), business model (manufacturing and dealer distribution), and target customer (residential pool owners seeking energy-efficient heating). Competes head-to-head for the same dealer relationships and pool heat pump market share.

Broad incumbents

• Pentair: Pentair is a global water treatment and pool equipment company offering pumps, filters, heaters, automation, and water management systems. Heat Siphon explicitly supports integration with Pentair automation systems (LX100EX/LX100EZ via EC Mode). Competes broadly in pool equipment with Pentair's heat pump offerings and benefits from being a complementary automation partner.
• Fluidra (Jandy/Zodiac): Fluidra is a global pool and wellness equipment conglomerate owning Jandy, Zodiac, and other pool brands. Heat Siphon's website history page notes that Jandy acquired Air Energy (another EUS spin-off) to enter the heat pump category, explicitly citing Heat Siphon's technology as the inspiration. Competes in pool heat pumps while also offering broader pool equipment lines.
• Rheem: Rheem is a major US manufacturer of water heating, HVAC, and pool/spa heating equipment. Comparable as a broad thermal equipment incumbent offering both traditional gas and heat pump pool heaters across residential and commercial segments. Provides useful benchmark for pool heater category dynamics even though Heat Siphon specializes more narrowly in pool heat pumps.
• Hayward Holdings: Hayward is one of the largest pool equipment manufacturers in North America, offering pumps, filters, heaters, and automation. Hayward acquired EUS Inc.—the predecessor company where Heat Siphon's founders originally developed pool heat pump technology. Directly competes with Heat Siphon in the pool heat pump category via its heat pump line, while also offering gas heaters that Heat Siphon does not.
• Carrier (pool and HVAC): Carrier is a global HVAC and refrigeration major producing heat pumps, air conditioners, and related thermal equipment. Comparable for the underlying heat pump compressor, heat exchanger, and control technology used in pool applications, and competes in commercial-scale pool heating where Carrier's broader HVAC infrastructure provides distribution advantage.

Emerging players

• Maytronics (Pool heat pump division): Maytronics is best known for robotic pool cleaners but operates in the broader pool equipment category. Selected as a peer given overlap in pool automation and dealer channels; Heat Siphon's POD and PASSPORT controllers integrate with pool automation systems similar to Maytronics' ecosystem. Less direct in heat pumps but represents the adjacent smart-pool category trajectory.
