Is it easy to change out thermostats, I have electric heat, my house was built in 54, the thermostats look like they are that old, brass no numbers that I can see, just says cold and warmer. Sue

Hi Sue. Being that old, they are probably the old mercury switch on a spring type and usually only have 2 wires to turn the furnace on and off. You can still get mercury 2 wire switches, slider and round, so far as I know. ( I have a couple out in the shed) Other HVAC experts here may chime in and assist you further. :)

What furnace ?
Furnace is a generic term for you heating system....some are gas....some electric.....technically still a furnace....electrically heated furnace.

Just buy a moderan thermostat......they will have instructions on how to wire it.....even if it's two wires.

Just make sure you unplug the furnace (electric heat) before you swap it out....there will most likely be 24Vac on those 2 wires...

Don't stress over it.....the instructions are pretty clear.

Not a problem. :) It's what we live for here! :laughing:
Do you happen to know what type of heat/fuel you have?
Being that old, you may (if affordable) consider upgrading to a new system that is more fuel efficient.

Good advice.....especially if your heating is electrical resistive heating......

A heat pump will be a lot more effecient....in many cases saving enough in electrical costs to pay for itself in 5 years or less.

To me it sounds like she has baseboard heaters, seems like she has more then one thermostat.

They are usually two wire. Turn power off, take off old and put back new as the old one was. I beleive you can buy programmable thermostats for baseboard heat as well now a days.

It is baseboard, and I have three thermostats, I just took one apart and it is two wires so I'll get what I need and if I'm still standing, I'll let you know how it went. Thanks

I didn't see any good advise here.Call an electrician.
I disagree.

Hooking up a 2 wire thermostat is a perfect example of a DIY project that any home owner can handle.

The operating and programming instructions are much more complicated than hooking up 2 wires. We told her to turn off the power first....after that it is easy. This is not a project that needs an electrician.

Sorry, but your comment is of the trolling type.
