I don't turn it on until someone calls to complain its too cold. My response is, "oh, it's not working? I'll be by to check it!" Saves me some money from not running and I can be the good "fixing" stuff landlord. --174.236.xxx.xxx

The law in NH is that as soon it drops below minimun average of 65* degrees. --66.87.xxx.xx

In NJ it is required when the daytime temperature drops below 68 degrees. As soon as I am cold and I turn mine on, I turn the heat on for tenants. Makes no sense to make people uncomfortable and decide to leave. --69.141.xxx.xxx

The best way is to automate the heating system by installing a electronic boiler controls. There is a sensor on the outside of the building then one sets the outside temperature the heat comes on. In the apartment building using a Tekmar electronic boiler control system which controls two high efficiency gas boilers and the temperature of the indirect hot water tank. Tonight if the temperature drops below 10 degrees Celsius the heating circulation pump comes on and boilers fire to maintain the indoor temperature to 21 degrees Celsius or 70 F under the imperial system which is required by the town bylaws. Most days during the spring and fall heat is not required during the day. So the cost of installing a electronic boiler control system is often paid for in less then heating season. One is saving natural gas, electricity along with less and tear on the heating equipment. Most town, city bylaws require a minimum temperature for the apartments so as long as the minimum temperature is maintained then one only needs the heating system when required. This week had some very warm days where one could have gone to the beach. Tonight it is likely the heat will come on. The high tomorrow may be only 12 to 14 degrees. --74.220.xxx.xxx
