BioTherm has introduced an advanced boiler line with capacities up to 10 million BTUs (2930 kWh), making it suitable for greenhouse operations of all sizes. The design of each system incorporates a cascade strategy, where multiple boilers share the energy load. This ensures operational reliability, energy efficiency, and a fail-soft/safe backup in case of unit downtime.
“These aren’t just boilers—they’re smart systems,” said Jim Rearden, President of BioTherm. “By incorporating cascade capabilities and on-demand performance, these units respond exactly when growers need them, without wasting fuel or energy.”
The boilers’ low-mass design allows for rapid heat-up and cool-down, operating at lower water temperatures that enhance plant health and compatibility with alternative energy sources such as heat pumps and solar thermal. Growers can also incorporate CO₂ enrichment by capturing boiler exhaust, creating a dual-purpose solution that supports both heating and photosynthesis.
RBI boilers offer a range of features ideal for horticultural and controlled environment agriculture (CEA) applications. These include high-efficiency condensing and non-condensing models, which contribute to energy saving and improved crop performance due to their low-temperature operation. The boilers also offer modulating and cascading capabilities, providing flexibility within the system. They are designed to be compact and space-saving, allowing for easy integration with BioTherm’s hydronic heating, irrigation tempering, dehumidification, and CO₂ systems. Additionally, the boilers deliver heat on demand, ensuring that no fuel is wasted in maintaining thermal mass.
BioTherm will be exhibiting at both GreenTech Amsterdam (Booth 01.545) and Cultivate in Columbus, Ohio (Booth 217). The company welcomes the opportunity to answer questions, explore heating needs, and show how its new boiler solutions can elevate growing environments.
