Closed Loop Radiant Floor Heating Systems

The decision is strictly up to the consumer for which they prefer.

Closed loop radiant floor heating systems. More advanced systems include industrial process equipment medical applications dehumidification coils and units and other hydronic heating applications. Pex tubing is flexible easy to install and provides all the characteristics one would need to create a successful open loop or closed loop. Radiantec s closed system uses a high efficiency water heater or boiler to heat water or another heating fluid such as anti freeze. What is an open loop heating system.

You can combine a closed radiant system with baseboard radiators. Radiantec recommends using a quality domestic water heater instead of a boiler in underfloor radiant heating systems. It is any system where you mix heating water and drinking hot water potable in the same system. 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.

Several decades ago pex replaced polybutylene pb in open loop and closed loop radiant heating installations and the landscape of geothermal heating systems changed forever. Why we do not recommend open loop 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. Air vents remove any trapped air in the.

These are only a few basic systems. Closed loop and open loop systems will remain at the foundation of any radiant heating system. 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. Manifolds and control systems connected to in floor radiant heating.

Many reasons have contributed to this evolution but the change was inevitable. The heating fluid is self contained within the system and stays there unless removed for maintenance completely separate from the domestic hot water when radiant heat is called for by the thermostat a pump comes on and circulates the warm water throughout. Too much glycol will therefore increase energy costs as the system works harder to accomplish the desired heating or cooling. Closed systems are familiar to code officials and contractors and they encounter little resistance.

The system requires an expansion tank.
