Integrated Heat Solution for Greenhouse Horticulture

Written by: Chrétien Hendriks

Genap and Sprinkler Energy have developed an integrated heat solution to meet one of the biggest challenges in modern greenhouse horticulture: ensuring a reliable, cost-effective and sustainable source of heat as the sector accelerates its transition away from fossil fuels.

Water-Based Heat Integration

At the centre of this solution is a system that combines water, heat and electricity into a unified energy concept. Low-grade thermal energy is captured in a water reservoir and upgraded using a water-to-water heat pump to produce usable heat for greenhouse climate control. The generated heat is stored in an insulated water buffer, making it available when demand or energy costs are high.

The system operates as an integrated whole. In colder weather, an auxiliary air-to-water heat pump supports the process, helping maintain stable source temperatures and preventing freezing. Sensors and advanced control technology continuously coordinate heat generation, storage and deployment, ensuring a secure supply even during peak winter demand.

Aligning Energy Generation with Demand

By producing heat when electricity is abundant, cheap or generated on-site and using that heat later, greenhouse operators can achieve more flexible and cost-effective energy management. Thermal storage decouples heat production from demand, reducing reliance on fossil fuels and enabling growers to better align energy use with operational needs.

Sector Trends: Transition, Innovation and Investment Support

The greenhouse horticulture sector is undergoing a significant energy transition driven by sustainability goals, rising energy costs and climate commitments. Growers are increasingly adopting integrated technologies that support carbon reduction, resource efficiency and operational resilience.

Alongside technological innovation, there is growing interest in investment support mechanisms—such as grants, incentives and financing programmes—to help horticultural businesses implement energy-efficient systems. These forms of support can make sustainable heat solutions more financially accessible and accelerate adoption across the sector.

Towards Future-Proof Heat Supply

This collaborative concept demonstrates that future-proof heat supply in greenhouse horticulture requires integrated, smart systems rather than standalone components. By combining water storage, heat pump technology and intelligent control, growers can reduce dependence on traditional fuels and position themselves for a sustainable energy future.
