If you have a furnace for your home and it is getting older, it may start having problems. Knowing about these problems can help you get the furnace repaired quicker, which may extend its life. Below are two problems it can have.
Not Heating
If the furnace is not heating, this can be due to many things. One of the easiest is to check the thermostat. Make sure it is set to heat and that it is at the right temperature.
Steam boilers rely on both adequate water and pressure levels. The internal vessel on your boiler has both water and air inside. The air acts as expansion space, providing the steam somewhere to go as you heat the water. When your boiler turns on, the vapor displaces the air as it travels through the system to your radiators.
If you look at your boiler, you should see a tube filled with water somewhere outside the unit.
