Thanks Harold, I spoke to the owner of the local plumbing store and he didn't say too much about the outdoor reset control. He said in my situation (with the tennant that controls the thermostat turning the heat high) he would advise a special tamper proof thermostat (it sounded like he was describing a unit with a independent thermometer inside) that unless an ice bag was placed on the top, you could not tamper with. However, when I told him I had a milivolt system he said it would not work. I looked on the web and could only find info on an outdoor reset control for large commercial boilers. Do you have any suggestions for a different thermostat? : An outdoor reset control could modulate the boiler water temperature with the outdoor temperature. The control can be set to permit the tenants to move their room temperature up a few degrees with their thermostat, but not drastically, so there would be far less waste of fuel. The control can be installed near the boiler in a lock box with remote sensors for the outdoor temperature and water temperature. It is far less expensive to install this control than replace boilers, so give it a try first.
