Why is air detrimental to a hydronic heating system?
L
What is the definition of an air trap in a hydronic heating system?
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.
How do you fill a forced hot water heating system?
Open a vent valve to purge the air and open the supply valve to let in water. Every hydronic (forced hot water) system has a system fill or supply valve, often connected to domestic cold water through a flow-check valve and a pressure-reducing valve. However, simply opening this valve with the rest of the system closed will merely pressurize the system with air. The system should also have one or more automatic air vents, plus a purging valve or two. By allowing air to vent (often out the top) and air bubbles to pour out through the purge valves, you can mostly fill the hydronic system with water. As the system is then heated, more air bubbles will form from dissolved air and be vented by the automatic vents. If it is not automatically vented, the top-most loop of the system may accumulate air and stop working until it is purged by opening a vent until water comes out.
What is the difference between a hot-water heating system and a warm-air heating system?
A hot water heating system (hydronic) uses heated water to circulate from a boiler to baseboard radiators or convectors, where the heat is wanted. This is done through a series of piping and pump(s) that move the heated water around. Warm air systems use a furnace to heat air and a fan to move the warm air through ducts to the point of use.
How do air get in to hydronic heating system?
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.
What is the definition of a high point in a hydronic heating system?
This means the highest point which the piping attains. typically referring to where trapped air will go and be vented or bled out.

How does air get into central heating or radiators?
Air can enter central heating systems or radiators through bleeding valves or leaks in the system. When air pockets form in the system, they can disrupt the circulation of hot water, reducing heating efficiency. Regularly bleeding the radiators can help remove trapped air and ensure proper heating.

How To Decide On Radiant Heat Flooring?
Imagine waking up on a cold morning and stepping out on a warm floor. This is great, especially if the normal climate is cold, such as in the winter months or in the mountains. An experience like this is possible through a radiant heating system installed underneath the floor. Radiant heating consists of heat generated through either electrical heating elements or heated water. Both types of systems are installed underneath the floor, thus the entire house is warmed as a single unit. How does one choose whether this system is the right one? Here’s how. 1) The first step is deciding whether to purchase an electric or hydronic radiant heating system. Electric systems are easier to install and cost much less than hydronic systems. They also eliminate a lot of the labor costs because the electrical heating system can often be connected directly to the system already present in the home. Hydronic systems require tubing to be placed beneath the floor, pumps to move the hot water, and probably a second boiler or water heater. In addition, the tubing is usually placed beneath a concrete floor, which means the additional expense of pouring concrete, letting it dry and installing the tubing before pouring. 2) The existing flooring can partially determine the choice. Since electric radiant heating requires a space between floors in order to insert the electrical elements. The good news for a hydronic system is that the floor does not need to be remodeled in order to install it; the joist underneath the subfloor will usually work fine. If the decision is made to remodel the floor, concrete or ceramic tile works best with radiant floor heating, especially with a hydronic system. The heat from the water is easily conducted through the floor into the air of the house. 3) There is one downside that makes hydronic radiant heat systems more attractive than electric systems: electric systems cost more in the long run than hydronic systems. For this reason, there are typically installed only in a small part of the house, like a bathroom or bedroom. Hydronic systems actually save up to as much as a third from the yearly heating costs.
What type of central heating system circulates hot water through radiators to warm a room and also creates warm air that is blown into a room through a vent in a floor or wall at the same time?
The question asked isn't well qualified but it sounds like there is hydronic baseboard with an additional heating coil in an air handling system but that is not a typical installation so what kind? I would say "Custom" it doesn't match up with standard types of installations
