Transom Heat Pumps is a Canadian manufacturer specializing in high-performance commercial heat pump systems designed for efficient heating and hot water production in demanding, cold-climate environments. Based in Barrie, Ontario, Transom combines over 30 years of HVAC engineering expertise with advanced manufacturing to deliver reliable, low-carbon alternatives to traditional boiler systems.
Focused on decarbonization and electrification, Transom’s solutions are engineered to produce high-temperature hot water—even in sub-zero conditions—making them ideal for retrofits and new construction across a wide range of commercial and industrial applications.
Product Offering
Transom offers a comprehensive lineup of modular, high-temperature heat pumps designed for flexibility, scalability, and performance:
- Air Source Heat Pumps – Systems such as the HATCH and TRENT series deliver high-temperature water using ambient air, with reliable operation in low outdoor temperatures.
- CO₂ Heat Pump Systems – The SIMCO₂E platform uses natural refrigerant (R744) to provide ultra-efficient domestic hot water with minimal environmental impact, capable of meeting 100% of demand in many commercial applications.
- Water Source Heat Pumps – The SEVERN series leverages water-based energy sources to deliver consistent, high-efficiency heating for large-scale systems.
- Modular Configurations – Systems can be installed as single units or combined in multi-module arrays to match project capacity requirements and provide redundancy.
Across all product lines, Transom heat pumps are designed to deliver high leaving water temperatures (up to ~175–190°F), integrate seamlessly with hydronic systems, and support building-wide electrification strategies.
