To overcome the above limitations, offers specially designed and affordable controls which allow to extend the heating capabilities to 1,500 sqft for 120V systems and 3,000 sqft for 240V systems respectively.
ft and therefore allow heating floors up to 15A/(0.5A/10sqft) = 300 sqft total. Similarly, 240V systems draw 0.5A per 10 sq. feet of heated space (at 3” standard cable spacing), it is limited to 15A/(1A/10sqft) = 150 sqft. Since 120V HeatTech floor heating system draws 1 Ampere per 10 sq. In particular, Honeywell floor sensing thermostats sold at are limited to a total load of 15 Amps per unit. This restriction is caused by the current load limits present on the thermostat which controls the system. While using the same principle, an electric underfloor heating system may actually heat the floors quicker simply because there’s no water heating and circulation is involved.Įlectric heating systems – size of the heated area which can be controlled using a single thermostat is limited to 150 square feet for 120V heating systems and 300 square feet for 240V systems respectively. PEX tubing generally comes in rolls of 250, 300 or 500 ft depending on the diameter. Hydronic – PEX tubing (cross-linked polyethylene) carries hot water to the heated area and transfers heat to the flooring and consequentially to the surrounding environment. Electric floor heating cable is supplied either on spools or pre-spaced and secured onto fiberglass mats for faster and easier installation. The heated floor, in turn, acts as a single large radiator and heats up the surrounding environment, whether a kitchen, shower, or a bathroom tile floor. In an electric heat system, a specially designed cable emits heat when powered and this heat is transferred to the flooring underneath which the cable is installed. Carpet is worst suited for radiant floors, as it has an inherently high R value and low heat transfer and heat distribution properties. Hardwood and laminate are also considered suitable, although they have lower thermal conductivity than ceramic and stone tile flooring. Flooring such as tile, stone, granite and marble are best suited in warm floor applications. The optimal flooring type for a radiant heating system is the one with greater thermal conductivity (heat transfer) and lower R value (resistance to heat transfer). While different fundamentally, these systems essentially represent the same type of energy used to heat the floor and create a warm, comforting and inviting home atmosphere.
