#240v electric radiant floor heating install

If you tried to heat a large area with 120v systems, you would need more material and therefore more thermostats to power them. The more heating systems and thermostats you need to purchase will affect the total cost. The 240v products use less amps which might help if you have limited space/breakers in your electrical panel.Add up the total amount of amps your heating system(s) will use to warm your area and you will know how many systems and thermostats and you will need to purchase.More than that and you need to purchase a relay or an additional thermostat depending on whether your use a standard thermostat or 3iE. No matter whether you are using one or several heating systems, each specially designed thermostat that will power them can handle 15 amps max.This information will help you determine exactly how much material you will need. As you will note on each flooring page, there is a product link where you can see the sizes available, their respective volts and the amount of amps each size will draw.120v systems provide more options for covering smaller areas similarly, 240v systems provide more options for larger areas. Once you have measured the space you are trying to heat (remember to exclude any permanent fixtures from your calculations, such as cabinets or bathtubs, showers, etc., and factor in a 2” perimeter) you will know how much material you will need to purchase from us.Why? Here is the reasoning behind this recommendation: If that flooring company can't give you any good reasons to use their 120v version, then go with the 220- 240v.Īs a rule of thumb, when you are heating an area over 120sq ft., you will likely use a 240v system(s). Then there is no finger pointing ability if it has a problem.

I would buy it from the same place you are getting the tile from and have their installer install it with the tile. It may heat up a little faster, but that can be dependant on the system itself and may not matter if you turn it on early enough. The 240 usually isn't designed to get much hotter, or it might damage the wiring. It probably won't make much difference if you are just getting the chill off of a small floor. It also uses the whole phase instead of throwing half of it away, so it can be more economical. Generally, 240 is easier on wiring and equipment. If it is reduced to go only one way, it is called 120v, and if it goes both ways it is double that, or 240. The current goes both ways through the wire, first one way then the other. (It is the same as 220) AC means alternating current. Choose the mesh kit that is best suited for the size of the room/area and configure on-site to provide floor heat in the desired areas of the room.Usually, the 240 volt is better. Mesh kits can be controlled using the WiFi programmable and non-programmable thermostat for home options (thermostats sold separately). The heating wire is attached to a roll of adhesive mesh material. Mesh is best suited for square and rectangular-shaped areas with some on-site flexibility. The nVent NUHEAT Mesh floor heating system is suitable for bathrooms, showers, kitchens, dining rooms, halls, entryways, and other living areas. Simply roll out onto the subfloor and cut/turn the roll (be careful not to cut/damage the heating wire) until the desired underfloor heating area is covered. The nVent NUHEAT Mesh floor safe heating system consists of a heating cable attached to a self-adhesive mesh which allows installers to stick the heating system onto the subfloor during the layout process. NVent NUHEAT Mesh is an easy-to-install and modifiable electric flooring installation kit best suited for square or rectangular areas where onsite adjustments are required.
