Snow Melting Install- From Start to Finish
This webinar covers the entire process of how to install an electric snow melting system in an asphalt driveway. From start to finish, you’ll get the inside scoop on the steps and install tips that will make your project a success.
Welcome to our snow melting under asphalt video as you can see a few of the leaves are falling here it's they say on TV winter is coming so we need to get this thing ready to go so what we're going to do is we're going to be installing tire tracks in this area in front of me and the area behind me right here we have our electrical connection spot we're going to be putting a junction box in there and then it's going to make it easier for the homeowner to make an exit out of this make a little roundabout area here that's going to be prepared with snow melting under an asphalt surface remember whenever you're planning some of this excavation you always have to call and make sure that you locate your electrical your gas your sewage that sort of stuff you can see here that the gas and the electricity have both been marked so we know to avoid these areas alright what we've done now is we've excavated the dirt and we've taken a steamroller and rolled it down what's next is about six inches of compacted gravel they're going to dump it in here then spread it out then they're going to compact it down because after that six inch layer we're then going to put a two inch binder coat, put the heating cables over that binder coat and then put a two inch top coat on top of that now we have the second layer of gravel in, the gravel has been compacted and now we're just beautifying the edges at this point getting the excess dirt out of the way so when the paver comes in the machine doesn't get held up by anything along the edges what's also going to happen at this point is instead of this rough edge around this perimeter
Here they're going to take a sawe and cut a nice straight edge into this okay we have the binder coat down what we're going to do now is we're going to take the rolls and roll them out what what's going to happen here is we are going to stake them in place and that's going to keep them tight then the guys are going to shovel asphalt over the top of these you never ever run a machine a paving machine over the top of the cables so we're going to lay them out and as they're pouring the concrete on top with shovels I'm going to be pulling them to keep them tight until we get down to the spot where our next group of wires are going to be.
Right now what we've done is we've measured out the distance because this is tire track coverage so you need to make sure that they're the correct width and that's what we've already measured and got them set out for so we're going to go ahead and get started okay here we can see where all the electric is going to the asphalt so you can see we have four mats right now we have four pieces of conduit going in for each mat and we also have a conduit going in here for the low voltage temperature sensor okay the job has been paved over and the guys have left and what's left behind is this junction box so this spot right here is where the mats are being attached to the power supply coming from the house now this box a lot of times can be hidden it can be put in the ground if you have a an in ground box you can use those some people like to put them in a decorative wall but the one thing is you have to be able to get at them if something ever goes wrong you need to be able to get inside the junction box to disconnect reconnect to do your testing so the box can never be completely sealed off you always have to have good access to it. So now we're inside the house and this is where the electrical part comes in we've installed the new controller up here on the wall and we've got it connected to the wires running out to the driveway now what we're doing is working on the supply power that's going to supply the voltage to those wires we've also had to supply a supply circuit which is the power that the unit up here operates on so what you're doing is you're sending power to this box to make it control and keep it lit up to keep it working all the time and then we're sending power from the circuit breakers over here to be switched by the relays in this controller on out to the heating coils and make them melt the snow. Alright here we are we have a completed driveway and there's no way that you can tell that there is any electric heating underneath this surface except for one thing and that's the junction box right here so if you'd like to learn anything else about heating your driveway with electric heating products just check us out at www.warmlyyours.com
