Is there any advantage to a “low voltage” electric radiant system?
There is no advantage to a low voltage system. SunTouch and competitors have to deliver about the same amount of energy to the floor to Warm Your Floor & satisfy you. Low voltage systems use fewer volts and more amperage and SunTouch uses more voltage and less amperage – Ask an Electrician or Car Mechanic about the dangers of High Amperage – A car battery can really hurt you, but it is only 12 volts, and Low Voltage systems draw the same amps as Line voltage. Low voltage systems use Large transformers (think small microwave oven size) that we have found to be noisy, hot and hard to hide and with special ventilation requirements; and what is the transformer warranty? All North American homes have access to 120 Volt service and by code, you must install your SunTouch system with GFCI or ALCI protection. Fortunately, GFCI protection is Built-In to our controls. GFCI technology detects ground faults and they will disconnect the energy to your heating system within milliseconds if there is
