A thermo-spat is a regular home quarrel over heating settings, particularly during the winter months. These disagreements frequently centre on what temperature the thermostat should be set to when to turn on the heating and which rooms should be heated. Different comfort levels among household members can cause dissatisfaction especially if one favours a warmer environment while another is more concerned with energy conservation. Such arguments are common during the winter as people try to strike a balance between comfort and cost.
