Radiant Heat verses Hydronics
Both electric and hydronic radiant heat systems have certain advantages for specific applications. The following highlights the advantages Heatizon's low voltage radiant heat systems have:
 |
 |
Only a 17"x12"x9" Control Unit is required to run a low voltage radiant heat system. |
A Boiler Room is required to run a hyronic radiant heat system. |
The ZMesh heating element is installed directly under the floor surface without any floor buildup. The 12" wide ZMesh is rolled out over the area to be heated then nailed and/or stapled to the wood subfloor.
Gypsum or concrete slab is required for installing a hydronic system. It is estimated that it costs approx. $4.00 or more per square foot to install a hydronics in-floor heating system than it does to install Heatizon's in-floor heating system.
Electric radiant heat warms your floors evenly because it uses 100% of the system's enegery. 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.
