I recently took advantage of the Mass Save HEAT loan and converted from oil to gas. I replaced my old Weil-McLain boiler and Amtrol indirect water heater with a Burnham Alpine 105 and Superstor Ultra indirect water heater. The one component of the system that wasn't replaced was the thermostat in the living space. My current Honeywell C***00A is about 9 years old and I would like to replace it. I asked my installer and he said programmable units are of limited value with high efficiency boilers since the outside sensor controls the flame size. I called Burnham and they recommended a non-programmable set to a comfortable setting and leave it. They thought this would be the most cost effective way to go. This seems like a totally new mind set since we've been told over and over to go programable with a 9 degree setback to save energy. I'm lost. Should I keep my old Honeywell and set it to 68 deg. all the time? Replace it with a some "smarter" unit that works well with the Alpine? Get a simple manual thermostat? I want to save money and utilize the technology of the Alpine!
