True hydronic baseboard heat has an opening at both the top and the bottom of the wall unit with a finned copper tube running down its length. Because hot air is less dense than cold air, the hot air naturally rises. As heat is absorbed in the air surrounding the finned copper tube, it rises and flows out of the opening at the top. (convection) As this warm air leaves the heater it draws cooler air into the bottom opening which is then heated and flows out the top continuously as long as there is heat in the finned copper tube.

Ducting in a forced air heating system must be larger than the tubing in a hydronic heating system due to the differences in how air and water transfer heat. Air is less dense than water, requiring a larger volume of air to achieve the same heating capacity. Additionally, to maintain adequate airflow and prevent excessive pressure drops, ducts need to accommodate higher velocities, necessitating larger dimensions compared to the more efficient and direct heat transfer of hydronic systems. This design difference ensures effective heating and balanced air distribution throughout the space.

An air trap is where the air is bled out of a system normally, there is also trapped air in some poorly designed systems or systems with water having recently been added.

Installing a hydronic boiler system in a residential property can provide benefits such as energy efficiency, even heating distribution, quiet operation, and improved air quality.

An air cushion tank in a hydronic heating system functions by maintaining pressure and accommodating thermal expansion of water. It contains a bladder or diaphragm that separates air and water; as water heats and expands, the bladder compresses the air, allowing for the increased volume without causing excessive pressure in the system. This helps ensure consistent system pressure, reduces the risk of leaks, and improves overall efficiency by minimizing water hammer and cycling of the boiler. Ultimately, it contributes to the reliable operation of the heating system.
Hydronic heating makes the most sense in new construction where you will heat the entire house with the radiant floor heating system and have room for all the mechanical equipment and a source of fuel other than electricity.
This means the highest point which the piping attains. typically referring to where trapped air will go and be vented or bled out.
There are a few different companies that offer hydronic heating systems. The prices of these systems will vary depending on the system one chooses to purchase. Some companies that produce these heating systems are Greenheat and Ascot.
The benefits of using a hydronic system for heating and cooling in a residential building include energy efficiency, consistent temperature control, quiet operation, and the ability to integrate with renewable energy sources like solar panels.
