Comfort Cove Radiant Heaters

[Ernmang2]

I have seen a couple guys that have comfort cover radiant heat... could you guys elaborate... I am looking at hooking up 2 of the:

< c-20024_240v_2000watts_8.3amps_132"_$224 >

together it would be 16.6 amps they say dont exceed 16 amp with 2 units connected .6 amps should not be a big deal (any thoughts) I am hooking them up in the garage (800sq) my one heat duct from the house keeps it 40-50deg just looking to be able to bump it up to 60-65deg

Also was looking at a thermostat King ESP-230 (line voltage 22amp @ 240v)

Anyone have any thoughts on either of these.. please share

Thanks

I have comfort cove heaters in our new kitchen and dinningroom. We have been happy with them so far and it is going on the third year of use. When we put them in it was recommended that you need 10 watts per sq. foot. We used a 20024 and a 18024 model.
That gave a total of 15.8 amps. With 12/2 wire the total amps you should draw is 16 to stay in code. But I would think that .6 would still work for you. Are you planning on keeping the temp at 60 /65 all the time? With radiant it does take time to really notice the heat as it has to warm the objets in the room. Other than that I really like the cove heaters it has been below 0 for two weeks and the house is staying very comfortable and they are very user freindly to install.

We have the King Electric ESP230 thermostat as well as the ESP120. One is a single pole and the other is a double pole. We have older radiant ceiling heat circa 1971 with wires and plaster. We bought our first set about two years ago. Problems with the program. We would set the temp for 68 degrees and periodically we would notice that the room was like 73 or 74 degrees and it still wasn't shutting off. King replaced them not citing any specific reason. The second set had on and off switches which we really liked. But the second set had the same problems. It wouldn't happen every time but periodically which made it hard to figure out what the problem was. It has nothing to do with cycling or anticipator but the program itself not shutting down after it goes two degrees above the temp you had set it at. I just got off the phone with King they are sending us another set. Apparently there was a problem with program (we will see). About a year ago they had a batch of 300 that had a program flaw. The new ones don't have the on and off switch which was a nice feature for turning off certain rooms not in use. It has great features when it works. Our problem is the older radiant ceiling systems use higher amps and they really heat up nicely and crank the heat out and hold the heat but apparently the newer thermostats are not designed for the higher amps. At least that is the most recent info we have. I was told that we really needed a proportional control which cycles off and on quicker and these are not made to manage 30 amp system. When the manufacturer says the thermostat is for radiant it doesn't always mean all types of radiant, sometimes they don't understand it. The older radiant ceiling is different from the newer ceiling, the ceiling radiant is different from the flooring radiant.
