Correct temperature setting for hot water heat/furnace
I have a 2 zone Burham hot water heating system. It is currently set for 180 degrees F, but I notice there is a lot of short cycling. On very cold days the burner will turn on until the water heats up. After that, the zones will cycle the furnace off and on very rapidly- - usually on for a minute, then off, then on, then off, etc. etc.
What should I do to the furnace temperature gauge to stop this short cycling? Should I increase or decrease the furnace temperature gauge? Or is this just a "function" of the Burham system -- that it constantly tries to "top off" the temperature no matter what the temperature is.
I put all kinda of insulating pipe wrap on the exposed basement pipes, but I don't think this should make any difference.
The thermostats are ok -- typically I set them for 60 overnight, and it is asking the furnace to get each zone up to 65 or 66. The thermostats aren't cycling off and on.
