Saving on energy is common sense and responsible for today’s global warming problem.
Simply using your home thermostat by adjusting up when the AC is on and down when the heat is on will save. When not home you can raise up or lower down the temperature. Leaving it on all the time is like running your car when you are not using it. In Europe cars are made to shut off at traffic lights and auto restart when you lift off the brake.
You can operate your home without cost by just adjusting the thermostat when you go to bed at night , get up in morning, leave for work and when you come home at night.
Having a budget plan can keep your tank full and avoid running out. Running out can cause you to have issues with clogged nozzles and the boiler operating inefficiently. This will cause you to burn more oil and spend more money. Service fees can be avoided by not running out of oil.
