Overcurrent, Ground Fault Circuit Interrupter (GFCI), and Ground Fault Equipment Protection (GFEP) are all types of electrical protection equipment mechanisms, but they serve different purposes and operate in distinct ways. Attached is an explanation of each and their differences.
Preparing for your project
No, unfortunately you cannot use one 240V circuit to supply power to ALL controls / heating mats. Since the thermostats have GFCI protection built-in, those areas / heating mats will need to be supplied with Non-GFCI Protected Circuits.
A snow-melting system is most efficient when the slab is preheated. As a rule of thumb, a snow-melting system should start preheating for 1 -2 hours before the arrival of snow/ice.
If you are planning for a large project, Warmup recommends limiting the number of relays controlled by a single thermostats to 5.
Sheet vinyl is a great solution over an underfloor heating system as long as the vinyl does not have insulating properties greater than R1.5.
We highly recommend the use of polymer-modified adhesives, also known as “modified thinset.” Since the addition of the polymer compound creates a more dense bonding reaction during the curing process, this ultimately improves heat distribution. Acceptable tile adhesives include modified polymer self-leveler or thinset.
Before you order your floor heating system, there are a several things you can do in preparation. Read this before your start!
It is vital that the floor heating thermostat’s floor probe was not only installed but done so the right way. Click “Read More” for details. Make sure that the sensor probe is installed underneath the mat and placed equidistant BETWEEN two runs of heater wire.
It depends on a lot of factors, but a classic installation over ¾” plywood with NADWM mats would take about 30 minutes to heat from 60F to 80F. Click “Read More” for details.
To wire in 3-phase you need 3-phase supply power. Click “Read More” for details.
