Well, matters how cold you want to be....
If you don't want to freeze (literally) that would have to be 33 degrees.
It also matters if you have a temperature for your heater to go off at.
On my heater, it goes on it the temperature in the house goes below 67 degrees, but I live in CA.
This is up to personal preference, so adjust this if it doesn't work for you, but for maximum comfort and energy savings, i would recommend the following:
For a modern house with adequate insulation and a thermostat that maintains the temperature in the house very close to the setpoint: 69
For a modern house with less than adequate insulation, windows, etc: 71
For an older house with poor insulation, poor windows, etc: 72
72 degrees F.
Set it at 65 to 70 degrees Fahrenheit.
i dont know =D
As low as you can live with
I would set it at 73 degrees both for summer and winter.. if you constantly turning it up and down it will make your electric bill go up..
what should it be set at
TWO DEGREES
It is because your thermostat is taking time to warm up. It should eventually rise up to the temp. that you set it as.
personally, from experience, i set mine at 55 over the winter. if u have any pets, i would set it around 60-70...but it depends
21 cel
68-70f is adequate for most people.
Set thermostat to desired temperature; lets say, 70 degrees Fahrenheit, a few seconds will go by then the furnace should activate. Once the furnace heats the room to the set temperature the furnace should shut off.
I set the thermostat for 70 degrees.
As with any thermostat it is based on where the set point is on the temperature scale. On hot water tanks the thermostat opens the element circuit when the set point temperature is reached. For example the set point should be around 135 degrees F. When cold water enters the tank, the thermostat closes due to sensing a temperature lower than the set point is set at. When the water heats up to 135 degrees the thermostat open because the set point is reached.To test the thermostat shut the power off at the distribution panel for the hot water tank. To do this test the water in the tank should be up to temperature. Remove the wires from the thermostat that is to be tested. Make a diagram of how the wires were connected. Using a continuity tester (ohm meter works fine) place the leads across the terminals where the wires were connected. If there is no reading then the set point is satisfied and the circuit is open. Leaving the tester leads on the terminals, with a screw driver raise the set point to a higher value. The meter should now show continuity between the terminals. Turn the set point down and the terminal reading should open. If this is happening then that thermostat is operating fine. Reposition the thermostat to the original set point. If you are working on the top thermostat now do the same to the bottom thermostat to see if it is working also.See related link below.
