I have the "bubble" type of thermostat which stays at one temperature.
I like to bring the heat up to 65°F in the early evening and just before
the kids wake; but otherwise I want it back down to 50°F while we're all
Is there an inexpensive alternative to the bubble that can easily be
substituted that will just do this time-based temperature program?

I knew programmable thermostats existed, but are they pin-for-pin
compatible with the simple bubble thermostats?
In other words, can I just remove the bubble thermostat from the wall
somehow and plug in the programmable thermostat in its place?

No, your old thermostat does not have batteries. The bubble completes the
circuit when the temp goes down and breaks the circuit when the temp goes
up. The programmable thermostats need batteries for their lcd displays and
It varies. Nowadays, most have such low power requirements, they
simply use a battery such as a 9v. I have a setback thermostat on
it's 3rd year on the same battery. Back in the 70's, my dad put in
one that recharged itself, but had a mechanical timer. It frequently
ran down and I ended up running an AC adapter to it to keep it charged.
