I heat my home with a gas-fired hot water boiler (Crown). My digital thermostat is dysfunctional and needs replacing. I've purchased a RiteTemp 7-day programable thermostat similar to the broken one that takes 2 AA batteries. There are 3 wires connected to the old thermostat. Do I need to shut down the electric power to my heater in order to replace the thermostat? If I don't, is there danger of electrical shock or damage to the equipment?

Ok Obviously none of these people has ever changed a thermostat....lol
You don't need to turn the power off to change the thing.A thermostat runs on the same amount of power as a telephone or doorbell.There is no danger of electricution here.However if you are still skeptical.Go to your furnace and find the switch that just shuts it off.It will be obvious It is just like a regular light switch.
Then just follow the directions that came with your thermostat for hooking up the wires bc it is important to get that part correct.

The thermostat is low voltage and does not pose
a shock hazard, but you should shut down the system
before working on the controls to avoid possible
damage to the system.

Have you ever change a light switch without shutting off the power? It's the same process, positive, negative and ground! Just be careful and then put the batteries in!

I just replaced mine without power shut off. The signal wires are very low power as indicated by the very small wire gage used. If you're worried about it shut it off, it only take a minute.
EDIT: erndog10, why make the comment that no one here changed one? I SAID I did and you basicly repeated MY answer. Get your own answer. And a big thumbs down back at you, richie.

Always turn off the power - or at least the trip - when changing electrical items.

If you don't shut the power off, you run the risk of shorting out the control transformer. If you do that, you will probably end up buying a new control transformer. For a step by step guide, check out my source.
