Hydronic heating system

Radiant flooring system transfers heat directly from the hot floor to the people or objects in the room through radiation. floor heating system is more efficient than the baseboard heating or the usual forced air heating, as there's no loss of energy through the ducts.

The radiant flooring can be categorized in to three types: radiant air floors (air is the heat-carrying medium), electric radiant floors and hydronic (hot water) radiant floors. There are mainly two techniques that can be used for installing these floors: dry installation and wet installation. In dry installation, the radiant floor tubing is inserted between the two layers of plywood or the tube is attached under the finished floor or subfloor. In wet installation, a large thermal volume of a concrete slab floor or lightweight concrete over a wooden subfloor is used.

Hydronic Radiant Floor Heating System
Hydronic radiant floor heating system pushes the hot water out from a boiler through a tubing laid in a pattern below the ground. The tube carries the hot water to different rooms, dispersing the heat through the floor surface. It is a closed loop system in which the cooler water comes back to the heat source where it is heated again and then transmitted. hydronic system can use a variety of energy sources to heat the water like oil-fired boilers, solar water heaters and gas fired boilers. Of all these, gas-fired boilers are the best, especially for a newly constructed home and can be installed by using dry or wet installation methods. The water heater or boiler is connected to a manifold that comprises of a system of separate pipes that channel the water from a single source into multiple zones. the manifold, the heated water is transmitted through a pattern of PEX tubing by a re-circulating water pump. It is one of the most durable tubing that doesn’t get brittle over time and remains unaffected by aggressive concrete additives or water conditions.
