In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I currently have a Honeywell T451A thermostat (120 volt 2 wire on an oil hot water system. The house was built in the 50's and I am looking to replace it with a programable thermostat. Looking on line, I am getting confused, all hot water thermostats are listed as 24 volt. Do I curently have a 'Line Volt' thermostat? Can I use a programable electric baseboard 'Line Volt' thermostat as a replacement?
