VB has achieved Level 3 on the CO₂ Performance Ladder
Sustainability is central at VB, which means we also critically examine our own CO₂ emissions.
Reliable heating for high-tech greenhouses. Consistent heat, climate stability and CO₂ for plant growth.
Reliable heating is essential for high-tech greenhouses, especially in regions of the United States with colder winters. The boiler burns gas in a heat exchanger, heating water that circulates through pipes in the greenhouse. Excess heat can be stored in a buffer tank for use when demand is higher. Boilers can also supply CO₂ from flue gases to enhance crop growth.
VB's boilers integrate seamlessly with heat buffers, pipe heating, air-handling systems, and climate computers.
VB delivered the heating systems, CO₂ systems and the largets heat storage tank in the USA
Size: 11.3 hectares (27 acres), tomatoes year-round
Delivered: heating systems, CO₂ systems, heat storage tank
The heat storage tank holds 10,000,000 liters of water and supplies heat to the current greenhouse and future expansion up to 25 hectares (62 acres).

A greenhouse boiler is a heating system that generates heat by burning a fuel, usually natural gas or biogas. The heat is used for pipe heating, air heating, or storage in a buffer tank. In addition to providing heat, boilers can supply CO₂ from flue gases to enhance crop growth.
Condensing boilers generally offer the highest efficiency, up to 109%, by recovering latent heat from flue gases. Combined with heat buffers and advanced controls, they can significantly reduce energy costs. For sustainable projects, a hybrid setup combining a boiler with a heat pump may be the most efficient choice.
Boiler capacity depends on greenhouse surface, insulation, crop type, and climate. For a 1-hectare greenhouse, heating demand typically ranges from 800 to 1,200 kW. VB always performs a detailed heat balance calculation to determine the ideal capacity and system configuration.
For standard greenhouse projects, installation takes about 8 to 12 weeks. For larger or more complex projects, timelines may extend depending on system integration.
Yes. Boilers can supply CO₂ from flue gases, which can be reused for crop enrichment. This is one of the key benefits of a boiler installation alongside consistent heat supply and lower investment costs compared to alternative heating systems.
