wheel house thermostat options?

[MuleShack]

I've got a suburban furnace in my shack and it has a spring type thermostat from suburban on the wall. The problem is that on the lowest setting the temp is still at or around 60 degrees. I'm trying to keep the shack warm when it is not in use but want it to stay around 40-45 instead.

Does anyone know of a DC thermostat that doesn't need internal batteries that can accomodate this?

can you use an 24v AC thermostat in the house with a 12v DC current?

The spring type thermostats dont change when you tilt them like the mercury ones do...you can rotate the older mercury ones and manipulate the start and stop temps.

Do they make the mercury ones yet and if so would they be safe in a wheel houe that bounces around on the lakes and roads?

Digital would be nice, but I dont want to have to worry about replacing batteries in the thermostat.

What is a suburban furnace??

[bbqhead]

Suburban is a brand name furnace, Mostly used in travel trailers.

Muleshack, You can use the old mercury stat with the suburban furnace, Ir wont care if it is 24 or 12 volt.

I know you were looking to stay away from thermostats with internal batteries, but I picked a digital one up at Menards for $15 that takes 1 AA battery and it works sweet.

The lowest setting is 45 degrees and it comes with a remote. It also has fan and cooling settings (not that you'd be interested). If I have to replace the battery once a year I'm OK with it.

The reason I wanted to stay away from a mercury therm is that going down the road it would constantly be switching on and off.

vman11, I never looked into the battery life of the digitals, but i guess i would be satisfied if one AA lasted a full year. I have plenty of them with me in the supply bag. I bought a round one that we mercury free, but took it back because it didn't have an off switch. Not much else out there, so I may just invest into an economically priced electronic one.
