To avoid this problem and try to maintain some environmental responsibility while making our guests comfortable, we pre-set and LOCK our wi-if controlled thermostat for the whole house furnace to a maximum high of 70 degrees and a minimum low of 45 degrees (to keep our pipes from freezing). We also provide an electric oil filled radiator — a very effective, efficient and safe heater — in each bedroom and in the living room so guests can have additional, safe and energy efficient heating if they need it. The oil filled radiators will not overheat or cause a fire hazard, but they do add a nice warm, consistent and gentle heat that you can “cozy up to” and our guests seem to like them.
We keep one in the back of the closet in each room and guests can easily roll them out and plug them in if they need extra heat.
