I am planning on having my circulator pump running all the time (most new circulators have 3 speeds) since I will have a storage tank and a heat exchanger to my home pressurized propane boiler. I think the inside of the firebox (from firebrick to firebrick and top of combustion firebrick) is 27" wide by 26" deep by 22" high (to the top of the top firebrick).
I have been thinking about a secondary fuel source (ex. an oil boiler) heating the same set of rads as the wood boiler. I'm still go with the thermostat though. The reason is that the propane or oil boiler wouldn't be running all day and I'd just be circulating relatively cold water, wasting electricity and making noise.
