Benefits of Radiant Heat Radiant Heat Defined Radiant Heat Applications Electric Radiant Heat vs. Hydronics Radiant Heat vs. Forced Air Low Voltage vs. High Voltage Electric Radiant Heating Systems vs. Hydronic Systems at a Glance Both electric and hydronic radiant heat systems have certain advantages for specific applications. The following highlights the advantages electric line and low-voltage radiant heat systems have: A boiler room is required to run a hydronic radiant heat system. A transformer is required to run low-voltage radiant heat system. Gypsum or concrete slab is required for installing a hydronic system. It is estimated that it costs about $4.00 or more per square foot to install a hydronics in-floor heating system than it does to install Warmzone's in-floor heating system. The FloorHeat heating element is installed directly under the floor surface without any floor buildup. The 12-inch wide element is rolled out over the area to be heated then nailed and/or stapled to the wood subfloor. Electric radiant heat warms your floors evenly because it uses 100% of the system's energy. A hydronic system, however, heats the floor less the further away the hot water gets from the boiler (see illustration below). Hydronic systems use only 65-85% of the system's energy. At higher elevations, electric radiant heat still is 100% efficient, where as hydronic systems are even less effective than at sea level.
