thermostats has 3 different types with 3 dead bands: 0.5 C. 1.0C and 2.C degree. The less dead band, the more often the furnace will start/stop. But your room temperature will keep more even and comfort. It means, if the temperature in your rooms changes 0.5 c degree, 0.5 degree difference from the setting temperature, the furnace will start or stops. But the 2.C degree dead band thermostat will not ask the furnace to start or stop.! K$ w# S0 ~3 E' q* \3 G9 J

The 2C degree dead band thermostat is only used in old house, with most mercury type, very simple. But you seldom can buy in the stores.: o6 Z6 A- M6 p% ^+ _

To check gas usage, the accurate way is to not the money as the rate is changing every month. You can check the number of the cubic meter you actually used in the gas bill. The gas bill shows the previous few monthes as well at the back side of the bill with bars in the graphic.
