When choosing a heating thermostat, it is important to consider factors such as compatibility with your heating system, ease of use, energy efficiency features, and smart technology capabilities. Some popular options include programmable thermostats, smart thermostats like Nest or Ecobee, and zoned heating systems. Ultimately, the best heating thermostat for you will depend on your specific needs and preferences. **

Without further information or context, it is difficult to determine if the thermostat is broken. Common signs of a broken thermostat include the heating or cooling system not turning on or off at the desired temperature, inconsistent temperatures throughout the home, or the thermostat display not functioning properly. It is recommended to check for these signs and consider consulting a professional if necessary. **

One easy way to calculate 800 + 800 in your head is to recognize that 800 + 800 is the same as 8 x 100 + 8 x 100, which equals 16 x 100. So, you can simply multiply 16 by 100 to get the answer, which is 1600. Another method is to add the hundreds first (800 + 800 = 1600) and then add the remaining zeros to get the final answer. Both of these methods can help you quickly calculate 800 + 800 in your head. **
