Closed Loop Radiant Floor Heating Systems

More advanced systems include industrial process equipment medical applications dehumidification coils and units and other hydronic heating applications.

Closed loop radiant floor heating systems.

If they decide that one system should be set up to run the homes radiant floor heating and potable services than an open loop system is required. The decision is strictly up to the consumer for which they prefer. Since most conventional boilers are designed to produce super hot water 185 degrees radiant floor company builds what we call split manifolds for multiple zone closed systems that use radiant floor heat in combination with standard baseboard radiators fan coils cast iron radiators or any other hydronic heating device that requires super hot temperatures. Types of hydronic floor heating systems image credit.

The system requires an expansion tank. You can combine a closed radiant system with baseboard radiators. Each length of pex begins in the utility core makes its circuit around its designated zone and comes back so that it will circulate the water in a closed loop heat system. There are essentially two different methods using a hydronic radiant floor heating system an open loop or a closed loop process.

I used zip ties to tie down the pex pipe. Closed systems are familiar to code officials and contractors and they encounter little resistance. An open radiant floor heat system is one in which the potable water that serves the drinking and bathing needs of the house is also used to heat the floors. In an open loop process the water is pulled from a source such as well heated and pumped once through the system before being discarded.

This i have personally seen being done around my neck of the woods. Closed loop and open loop systems will remain at the foundation of any radiant heating system. The above procedure can be followed to eliminate all air from the system. Radiantec recommends using a quality domestic water heater instead of a boiler in underfloor radiant heating systems.

Alternately a utility transfer pump not a sump pump can be used to pump fluid into the system and evacuate the air we recommend a powerful utility pump like the wayne ec 50 or the wayne pc 4 or an equivalent pump like the utilitech 5 hp cast iron transfer pump all of which can generate up to 45 psi. Manifolds and control systems connected to in floor radiant heating. Air vents remove any trapped air in the. Many reasons have contributed to this evolution but the change was inevitable.

These are only a few basic systems. As per the diagram plan all the pipes end in the utility core to be attached to the radiant floor system inside.
