Cold Start vs Hot Start ??

I have a natural gas 3 zone hydronic baseboard heat system. It is not used for hot water - I have a separate hot water tank. Question is that I noticed even on warm days that the boiler always fires to maintain a temp about 180 deg. even though there is no call for heat. Is it wise to change this so that the furnace fires only if there is a call for heat?

Converting to cold start

If the boiler has stayed hot for many years, you may create leaks by converting to cold start. It is a gamble. The upside is usually if reverted to staying hot, the leaks will stop. If the boiler is in a basement & subject to dampness, especially during the summer, you could get a lot of rust in the flueways.
