Fulton - Maximize Performance & Sustainability: Hydronic Solutions for the Future
The latest SVL Coffee Break Webinar brought together industry professionals to discuss the future of hydronic systems and their role in driving energy efficiency and sustainability. Led by Joel Southwell, VP of Sales at Fulton®, the webinar explored how hybrid hydronic system design is shaping the industry by integrating cutting-edge heating technologies like condensing boilers, electric boilers, and air-source heat pumps into one intelligent system.
Why Hydronic Systems?
Hydronic systems are a proven method for building heating and cooling, offering energy efficiency, comfort, and sustainability. With a growing focus on decarbonization, these systems are at the forefront of green building initiatives.
The discussion underscored the importance of:
- Lowering carbon emissions to align with national sustainability goals.
- Reducing energy costs through smart system design.
- Providing reliable, long-lasting heating solutions adaptable to different climates.
Decarbonization & The Push for Sustainability
Southwell highlighted the U.S. Department of Energy’s Blueprint for Decarbonization, which aims to cut greenhouse gas emissions by 65% by 2035 and 90% by 2050 compared to 2005 levels. With HVAC systems being the largest consumer of energy in commercial buildings, the industry is seeing a push for high-efficiency solutions.
Understanding Scope 1 vs. Scope 2 emissions is critical in this transition:
- Scope 1 emissions are direct emissions from on-site energy sources, such as gas-fired boilers.
- Scope 2 emissions come from purchased energy, i.e. electricity generated by fossil fuel burning plants.
By integrating low-emission technologies, hydronic systems can help reduce both types of emissions.
Hybrid Hydronic Systems: The Future of Heating
One of the key takeaways was the shift toward hybrid hydronic systems. These systems combine different heating technologies into a common loop and optimize energy use through an intelligent control platform.
A well-designed hybrid system includes:
- Condensing Boilers – Reliable, high-efficiency heating with low operating costs
- Electric Boilers – Zero-emission alternative that’s ideal for sustainability goals
- Air-Source Heat Pumps – Uses ambient air to provide low-energy heating
The system is controlled by a hybrid control platform, which automatically adjusts heating sources based on outdoor conditions, energy costs, and building demand. This adaptability helps building owners maximize efficiency while lowering energy costs.
Addressing Industry Challenges
Despite the benefits, implementing hybrid systems comes with challenges:
- Upfront capital costs can be higher.
- Existing infrastructure limitations may require electrical service upgrades.
- Varying climate conditions impact heat pump efficiency.
However, intelligent control systems and integrated design approaches help overcome these obstacles, ensuring seamless operation between different heat sources.
Fulton’s Commitment to Innovation
Southwell introduced Fulton’s latest advancements, including:
- Endura XE Condensing Boilers – Expanded range up to 6,000,000 BTU with high turn-down ratios.
- Endura ZE Electric Boilers – Highly efficient with up to 100-to-1 turndown capability.
- Air-Source Heat Pump Development – Fulton is building an environmental chamber to further test and refine heat pump efficiency in varying climates.
Optimizing Energy Use with Smart Controls
A highlight of the session was ModSync®, a BACnet-compatible hybrid control system that:
- Balances energy sources based on demand and pricing.
- Reduces emissions by prioritizing zero-emission technologies.
- Automatically adjusts heating based on outdoor temperature and energy rates.
By integrating real-time utility pricing, ModSync allows buildings to automatically switch between natural gas, electric boilers, or heat pumps to optimize cost and performance.
Key Takeaways
- Hybrid Hydronic Systems offer the best path to energy efficiency and sustainability.
- Smart Controls & ModSync help manage multiple heat sources for optimal performance.
- Electric Boilers & Heat Pumps reduce emissions but require careful infrastructure planning.
- Retrofitting existing boiler systems with new condensing technology can reduce carbon emissions by up to 40%.
- Hydronic systems are future-proof—designed for longevity, adaptability, and comfort.
Looking Ahead
As the world moves toward decarbonization and high-efficiency heating, hybrid hydronic solutions will play a vital role in reaching sustainability goals. Fulton and SVL continue to lead the way in developing smarter, more efficient heating systems that optimize energy use, reduce emissions, and maximize long-term cost savings.
