Electrical Wiring in the Home/4500w on a 4000w Line Power Thermostat


The jist of my question is the above. I have 3 - 6 foot space heaters that are from around 2002-ish I am told. My understanding is these are 220v and they are about 1500 watts each. Right now all 3 are hooked up a single dial 240v line power thermostat that is pretty much useless because it never turns off.

I'm looking at a programmable model, but I can only find a model that goes up to 4000 watts. Would I be running a serious risk if I was potentially putting up to 4500 watts through one of these? I assume they should be able to handle slightly more than what they are rated for, but I didn't want to push it.

If that wouldn't work, is there any potential to run a relay and install a normal thermostat? I have heard of it being done, but I don't know the logistics.

Many thanks -Mike


Don't exceed the limits of the thermostat. If you have a fire God forbid your insurance company could give you problems.

You could do a relay but that would best be left to a qualified professional to do as to where and how to wire that into your current set up.

Licensed contractor in Closter New Jersey.

"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
