I am replacing my thermostats for the baseboard heaters.

I am replacing my thermostats for the baseboard heaters. there are two baseboard heaters in the room, each with its own t-stat. The each of the two wall box has two sets of red/black wires coming into it. The existing t-stat sat between the two black wires and the red wires were joined together. There is 240v between one pair of black/red wires and the other pair of black/red have no voltage across them. I bought some Honeywell TL8230a1003 t-stats that have two pair of black/red leads. When I wire it as per the instructions, one t-stat powers up and the baseboard gets hot. The other t-stat does not power up and the baseboard doesn't heat up. Is there an alternate way to wire this second t-stat?JA: I'll do all I can to help. How long have you been dealing with this?Customer: About a half hour.JA: Do you plan on doing the work yourself?Customer: I do. I have an electronics background and I'm an architect who done plenty of home 120v wiring. Not real strong on the 240v - a couple of water heaqters to date.JA: How old is the system in question? And have you consulted an electrician yet?Customer: 1986. No, the engineer I usually work with took his kids to the city today and isn't reachableJA: Anything else we should know to help you best?Customer: Maybe. On the back plate of the new Honeywell t-stat, the wiring schematic show the inner pair of black/red leads being controled by the t-stat and the outer pair of black/red leads going to and from the load. Since the instructions didn't make a point of which pair of wires into the box should go to the inner pair of black/red leads on the t-stat, I connected the t-stat with the hot pair going across the control and the other par going to the "load" pair for the t-stat. Thing I should swap them?

I have an electric oil filled radiator space heater (this

Hi I have an electric oil filled radiator space heater (this model: http://www.homedepot.com/p/1-500-Watt-Electric-Oil-Filled-Radiant-Portable-Heater-HO-0218H/202295910). The 4 position switch (off-low-med-high) is broken so the unit doesn't turn on. I've attached a picture of the switch (type YX2, 13A 125V). The switch has 4 wires labeled 1, 2, 3, and A. Is there a way to connect the wires directly to bypass the switch and still use the heater, the same as if it were on medium or high all the time? I never leave the unit plugged in any way, so it doesn't matter to me that it would always be on when plugged in.

I am trying to replace electric baseboard heat thermostats.

I am trying to replace electric baseboard heat thermostats. I had an electrician come by today and he could not figure it out. There are two wires coming into the thermostat box from the heat strip. The are both 120 volts. The thermostat is a non programmable Honeywell 7000 pro with 4 wires. Do you have any suggestions?JA: How old is the system in question? And have you consulted an electrician yet?Customer: I think I just stated that the electrician did not know how to wire it. The heaters were installed in 1980. The 240 volts first goes to the units and then back to the thermostat box with 2 120 legs.JA: Do you plan on doing the work yourself?Customer: I just need to know the correct way to do it-then I can I will try to find another electrician.JA: Anything else we should know to help you best?Customer: I purchased Honeywell 7000 pro line volt 4 wire non programmable thermostats.

Need more help with my water heater tripping breaker. Ok,

Need more help with my water heater tripping breaker. Ok, replaced 3800w with 3000w elements. Still trips breaker. I checked all wire connections with a meter. All have continuity with each other. From thermostat to element and from top wires to the bottom wires. Are both elements trying to come on at the same time? Both temps are set at 120*. I've probably reset breaker at least 6-8 times. Can the breaker be faulty now?

We have a 1100 sqft vacation cabin which is rectangular in

We have a 1100 sqft vacation cabin which is rectangular in shape versus square. We always winterize it when gone, but wish to leave one propane heater on while gone, so that relatives who want to use it for skiing, etc. can do so without having to turn water on. The heater is direct vented through the wall and is controlled by a thermostat. Has a pilot light. If we left the heater on and set at 55 would it heat the entire cabin sufficiently that we would not have to winterize the water pipes and put RV antifreeze in the P-traps and toilet? The BTU output is 10,000. The heater is located on one end of the cabin and the heat has to travel out of the bedroom, turn right for 10 feet, and then opens into a large LR and Kitchen, with the other bedroom and utility room off the kitchen. The cabin is well insulated and tight. What do you think?
