What is hydronic energy?
Hydronic systems consist of an energy source (boiler, water heater, or chiller), along with the associated pumps and piping that connect the source to suitable terminal heat-transfer units located in the spaces.
What is the required thickness of hydronic piping?
The 2015 International Energy Conservation Code (IECC) requires insulation thicknesses between 1/2″ and 1″ for chilled-water lines below 8″ nominal pipe size (NPS)—depending on operating temperature and pipe size. For hot-water systems operating below 200 ° F, the 2015 IECC requires insulation thicknesses between 1″ and 2″. Most codes include an exception for those piping locations where heat gain or heat loss will not increase energy usage. For example, a piping run through a heated space to a unit heater would not require insulation since any heat loss from the piping would help offset the heating load on the space.
Why is hydronic water insulation used?

How does a hydronic air handler work?
Hydronic air handlers heat air evenly so that those uber-hot blasts of air don’t shoot out of the vents as they do with conventional heating systems. This is made possible thanks to the machine’s use of a boiler or hot water heater that sends water to hydronic heating coils. The user simply sets his house or zone thermostat to heat his living space and the system pump transports water from the boiler/hot water heater to the aforementioned coil. The water flows through an aluminum tin coil with copper tubing. Return air from the house is then pulled in toward the blower, above the heating coil. The warm air that is generated is then transmitted through the building’s ducts. The system’s water is recirculated to the boiler/water heater for additional heating.
Why use hydronic air handlers?
It has become quite popular because it requires less fuel, creates a more comfortable living or working space and produces little noise compared to a conventional furnace.
How does refrigerant work?
Refrigerant is applied via the cooling coil within the air handlers to transfer heat from the recirculated air to the cool refrigerant. The result is the transmission of cool air throughout the home.
Why is hydronic water heater better than conventional furnace?
This occurs because the hydronic air handler operates much more frequently than other systems. Water circulates through the boiler, decreasing the amount of sediment that has built up over time. The result is an increase in the machine’s lifespan, allowing it to out-live the traditional furnace.
