Residential Hydronic Coils
(AQUECOIL™) Installation
Residential hydronic coils, commonly known as AQUECOIL™ systems, are heating components that use hot water from a boiler to warm air as it passes through an air handler. This approach combines the comfort and efficiency of hydronic heating with the flexibility of forced-air distribution. Homeowners typically use hydronic coils when they want boiler-based heat delivered through ductwork rather than radiators or baseboards.
Hydronic coils are often used in homes transitioning from traditional heating systems or upgrading to more efficient boiler-based solutions.
How Residential Hydronic Coils Work
A hydronic coil is installed inside an air handler or duct system. Hot water from the boiler flows through the coil while air passes over it, transferring heat into the living space. This allows the home to benefit from hydronic heating while maintaining centralized air distribution.
Common Applications for Hydronic Coils
- Homes with existing ductwork and a boiler system
- Hybrid heating systems combining water-based and air-based components
- System upgrades replacing older furnaces with boiler-driven solutions
- Homes requiring zoning or air handler-based heat delivery
Proper system integration is essential. Coil sizing, airflow, and water temperature must be engineered together for reliable performance.
“A hydronic coil only performs as well as the system it’s designed into.”
When a Hydronic Coil Is the Right Solution
Hydronic coils are not universal solutions, but they are highly effective when used in the correct applications. Understanding when they make sense helps homeowners avoid comfort issues and inefficiencies.
Common Reasons to Install or Replace a Hydronic Coil
- Existing ductwork with a boiler-based heating source
- Desire to eliminate forced-air furnaces while keeping ducts
- Uneven heating caused by undersized or outdated coils
- System upgrades requiring better heat transfer and control
A proper evaluation ensures the coil matches both the boiler output and the airflow requirements of the home.
The Sumzero Approach to Hydronic Coil Systems
Hydronic coils require coordination between HVAC and plumbing disciplines. Every project begins with system analysis rather than assumptions.
What Homeowners Can Expect
- Evaluation of boiler capacity and water temperatures
- Proper coil selection and airflow matching
- Correct piping, controls, and safety components
- Clean, organized installation designed for long-term operation
Systems are designed to deliver consistent comfort without overworking the boiler or air handler.
“Hydronic coils are not accessories — they are engineered system components.”
