Radiant Heat Questions (sensor, thermostat, etc)
Looking at putting radiant heated floors into our very small master bathroom. Only need ~20 sq ft to cover an area that is ~36" x 82" in size. Have a few questions I am hoping someone can help with.
1) Mat coverage: We will have a vanity that is lifted 7" off the tiled floor on 4 legs. Can we have the radiant heat mat go under the feet, as that is where the typical toe kick would be and I don't want the area to be cold.
2) Thermostat: I have read that you these are interchangeable across brands (e.g. SunTouch mat with Honeywell thermostat) Is this accurate? What do I need to look for to be sure I am getting the appropriate thermostat to coordinate with my mat (volt, etc.). Any recommended or suggestions as to what to look for when shopping for thermostats?
3) Sensor: I have read on the boards about having a second sensor installed. Are they referring to an extra floor temperature sensor? Will we need an extra power lead as well? Is the sensor linked with the mat brand or the thermostat brand or neither? I am just curious since I am thinking of using different brands for mat and thermostat. I also don't see extra sensors sold for every brand.
4) Alarm: Each brand appears to have their own branded Loudmouth alarm monitor or something similar. Are these necessary? If so, are the brands interchangeable, since the price points vary a bit by brand.
5) Mat Wire spacing: I noticed Warming Systems brand spaces at 3". From what I can find NuHeat states between 1.5" -1.75", and other brands list 2.5" or don't state the spacing at all. Is there a noticable difference between spacing widths?
6) Brands: It appears that for mats, except for wire spacing, warranty and price...the brands all appear to be very similar. Anything I am missing? Is there something else I should be evaluating (electric use for example, although for a 20sqft mat I don't anticipate it being very high).
Based on the boards it appears most people have used NuHeat (most expensive) and SunTouch, with a few other brands like Warming Systems (least expensive) and Warmly Yours. Has anyone ever used the Laticrete mats? I haven't seen anyone mention them on the boards, but I figured I ask since they appear to be reasonably priced (but I don't see an extra sensor option).
