Federal Pacific thermostat and panel replacements

Hi,

My home was built in 1977 and has electric ceiling radiant heat panels throughout. They are controlled by Federal Pacific thermostats (see attached photos of front and rear with wires attached). One of these thermostats has stopped working properly. What do I replace them with?

I also have a Federal Pacific electric box with Federal Pacific breakers (I've been told that this needs replaced also at some point).

Really appreciate any advice. I've seen other forums that suggest Honeywell LineVoltPro. Also, I've read that I need to know the Amps precisely before replacing one of these, but I have no clue how to figure that part out.

You can replace with pretty much any 2 pole line voltage thermostats.

You could use 2 pole baseboard thermostat.

Welcome to the forums.

Most of the replacement line voltage thermostats are rated for at least 22A and are all you need for that type of heating load. What type of stat did you want ? There are similar replacements, electronic, programmable.

This one would be a direct replacement for what you have. Basic, accurate and wires with the same 4 terminals. HoneyWell-T498B1512-Electric-Voltage-Thermostat

Slightly off-topic, but...

I know the failure rate of Federal Pacific 2-pole breakers is substantially higher than the failure rate of single pole ones. (12% vs 1% according to one source.) But does anyone know how safety is affected by using the FPE handle ties instead, like the OP has there?

Wow, really appreciate the quick responses! Very helpful and makes me feel better about moving forward with a purchase.

I did see one question from @PJmax asking what type of thermostat I was looking for... I am completely open to something simple, but am also curious about any digital stat options. I'm not interested in anything programmable just because we have one in every room and I can't see myself having any interest in programming 10 of them!

The current handling is slightly lower on electronic stats as opposed to mechanical ones but the one Lambition linked to shows 3120 to 3600 watts which should be fine for your radiant heat.

It is rated for 15A, but since op's breakers are all 15A, I figured it will be fine.

Thanks again for all of the help... I ended up ordering the Honeywell T498 and will let you know how it works out!

Quick update folks... not only is the Honeywell T498 working well, but it turned out to be a cinch to install! Just like @PJmax suggested, the wires hook up practically identical to the old Federal Pacific model that I replaced. Thanks again! I wish I had found this forum 2 years ago when I bought our fixer-upper... would have saved me a ton of time!

Don't forget to replace that Federal Pacific panel. We rarely get to see the spectacular photos of the aftermath; instead, the member just stops posting. Undoubtedly because cemeteries are too cheap to install wifi for their tenants.
