These systems use simple electronic controls and may offer a floor sensor and optional set back or timerfeatures. By code, systems must be protected by a ground fault circuit interrupt device. More advanced features include whole-load carrying, fully braided grounded armor from one end to the other, fully braided grounded armor power leads and shielding. Hydronic Hydronic systems use tubing embedded in the floor to carry heated fluids that conduct warmth to the surface of the floor where it broadcasts energy to your the room. A zone is a floor area controlled by one thermostat and served by a manifold which distributes the flow of warm fluids to the individual circuits of tubing within the zone.
Boilers can heat water with natural gas, propane, electricity or wood.
Most hydronic systems use water which may be treated to improve its resistance to freezing or corrosion of ferrous system components. Advanced systems may include valves or injection loops to precisely control temperatures in each zone, and outdoor resets to anticipate sudden weather changes. Hydronic systems are also used with antifreeze solutions to melt snow and ice from walkways, parking lots and streets.
